Nuacht Mhall. Príomhscéalta na seachtaine, léite go mall.*Inniu an t-ochtú lá de mhí Feabhra. Is mise Barra Mac Giolla Aoláin.Rinne Uachtarán na Stát Aontaithe, Donald Trump, ráiteas neamhghnáth maidir le "togáil" Gaza, nuair a bhuail sé le Príomh-Aire Iosrael, Benjamin Netanyahu, le labhairt faoi chúrsaí síochána le Hamas. Dúirt Trump go dtógfadh Meiriceá smacht ar Gaza agus go gcabhrófaí leis an limistéar le fostaíocht agus tithíocht a chruthú. Mhínigh sé freisin gur chóir do na Palaistínigh imeacht go tíortha eile, amhail an Éigipt agus an Iordáin, rud a diúltaíodh go láidir sna tíortha seo. Ba mhaith le Trump go mbeadh Gaza ina "Riviera an Mheán-Oirthir," ach dhiúltaigh na Palaistínigh agus oifigigh Hamas go léir an plean go géar. Dúirt an Tánaiste go bhfuil réiteach dhá stáit riachtanach do mhuintir na Palaistíne agus Iosrael, agus d'aithin sé a imní faoi mholadh Uachtarán na Stát Aontaithe, Donald Trump, Gaza a "thógail". Ba é Eanáir na bliana seo, an mhí seo caite, an mhí Eanáir is teo riamh ar an domhan, a deir eolaithe, rud a chuireann ceisteanna faoi luas an athraithe aeráide. Ceapadh go mbeadh Eanáir 2025 níos fuaire ná Eanáir 2024 mar gheall ar El Niño, ach bhris an mhí seo caite taifead Eanáir 2024. Tá téamh na cruinne ag tarlú mar gheall ar astaíochtaí gásanna ó ghníomhaíochtaí daonna, ach níl eolaithe cinnte céard a rinne an mhí seo caite chomh te. Leanann sé seo sraith de thaifid teochta níos airde ó lár 2023. "Táimid ag briseadh taifid toisc go bhfuil níos mó gásanna ceaptha teasa san atmaisféar," a dúirt Gavin Schmidt, stiúrthóir Institiúid Goddard de chuid NASA. "Táimid ag iarraidh tuiscint a fháil ar na cúiseanna beaga atá ann." Faoi láthair, tá an chuid is mó taighdeoirí fós ag súil go mbeidh 2025 beagán níos fuaire ná 2023 agus 2024.Tá Túr Grenfell i Londain, a scriosadh i dtine chraosach sa bhliain 2017, le bheith briste anuas. Maraíodh 72 duine sa tine, a scaip go gasta tríd an fhoirgneamh mar gheall ar chumhdach so-lasta. Tháinig fiosrúchán chun críche an mhí Mheán Fómhair seo caite, agus dúradh gur tháinig an tragóid as laigí ón rialtas. Dúirt an Leas-Phríomh-Aire Angela Rayner le hoidhreachtaí agus le teaghlaigh na n-iarrthóirí go bhfuil an cinneadh déanta ag an rialtas an foirgneamh a leagan chun talaimh. Beidh freagraí measctha ag an chinneadh seo. Tá roinnt daoine sa phobal sásta go mbeadh sé á bhaint síos. Ach tá daoine eile ag iarraidh go mairfeadh Túr Grenfell mar chuimhne ar an tragóid.*Léirithe ag Conradh na Gaeilge i Londain.

In this episode of the ESG Insider podcast we explore climate change and its implications for property insurance through the lens of the wildfires in Los Angeles. The fires that broke out in LA in January killed at least 29 people and destroyed or damaged thousands of structures. Early estimates from AccuWeather put the total damage and economic losses at more than $250 billion. “Climate change is not the only culprit here, but it is an accentuating factor that made this event and other events more severe than they would have been otherwise,” says Terry Thompson, Chief Scientist in the Climate Center of Excellence at S&P Global. We also talk to Gavin Schmidt, Director of NASA's Goddard Institute for Space Studies, about why extreme weather events like wildfires are becoming more frequent and severe as the world warms. "We can prevent the situation getting worse by reducing, in the end to zero, carbon dioxide emissions," Gavin says. "There's really no practical other way to even stabilize the situation, let alone reverse it.” And we hear how the insurance landscape is changing in an interview with former California Insurance Commissioner Dave Jones, who is now Director of the Climate Risk Initiative at UC Berkeley's Center for Law, Energy and the Environment. Dave explains that some property insurers are raising prices and declining to write or renew insurance in places that face rising losses from disasters like the LA wildfires. “The increase in price of insurance and the increased unavailability of insurance has significant economic consequences for households and businesses,” Dave says. “Insurance is the climate crisis canary in the coal mine, and the canary is starting to expire.” Listen to our episode about Canadian wildfires: https://www.spglobal.com/esg/podcasts/how-the-canadian-wildfires-impact-business-net-zero-health Want to get in touch?

Episode 287 Chinese AI company DeepSeek unexpectedly stormed onto the scene just a few days ago - a move that has shaken the big US AI companies. The new large language model is similar to ChatGPT, but was developed for a fraction of the cost. How have they achieved this? We dig into the key technological innovations behind DeepSeek. We also discuss the potential climate gains of a more efficient AI model, whether this is the beginning of an AI-fuelled arms race between China and the US and perhaps most importantly - is it safe for you to use? All of this and a chat about the future of AGI - artificial general intelligence. Global ocean temperatures hit record highs for 450 days straight in 2023 and early 2024. This appears to be because the world's oceans are absorbing heat from the sun at an accelerated rate. As warming hits the highest rates predicted by climate models, what is causing this sudden jump? Amazon river dolphins have been caught shooting pee into their friends' snouts. A series of amazing images capture these dolphins, or botos, rolling upside-down and shooting a stream of pee into the air in a never-before-seen display. The team discuss why they're doing it. Hosted by Rowan Hooper and Madeleine Cuff, with guests Alex Wilkins, Jeremy Hsu, Chris Merchant, Gavin Schmidt and Patty Brennan.

Gavin Schmidt, climatologue en chef de la NASA, a admis que 2023 a surpris les experts avec des températures exceptionnellement élevées, parfois impossibles à expliquer. "2023 nous a rendus plus humbles, mais surtout, beaucoup plus inquiets. Cette année a défié toutes nos prévisions," confie-t-il. Selon Schmidt, les températures ont dépassé les estimations de 0,2 °C – un écart considérable dans le domaine climatique. Les causes principales du réchauffement sont bien connues : les émissions de gaz à effet de serre d'origine humaine, le phénomène El Niño (actif entre juin 2023 et mai 2024), la pollution émise par les navires, l'augmentation de la vapeur d'eau due à l'éruption du volcan Hunga Tonga, et l'intensification du cycle solaire. Pourtant, selon Schmidt, ces éléments n'expliquent pas entièrement ce pic de réchauffement.Alors que le rôle des émissions humaines reste central, les autres facteurs comme la pollution des navires et l'éruption du volcan Tonga ne contribuent qu'à une faible part du réchauffement observé. Les dernières études montrent même que l'impact refroidissant du volcan aurait surpassé son effet réchauffant. Schmidt souligne que la situation actuelle pourrait s'expliquer par deux hypothèses : soit les scientifiques ont sous-estimé la vitesse du réchauffement climatique, soit un phénomène inconnu agit en parallèle. Une étude récente dans le journal *Science* révèle que l'effet réchauffant d'El Niño a été bien plus intense que prévu, rappelant un bond similaire des températures en 1977.Avec une franchise saisissante, Schmidt reconnaît que l'évolution du climat devient de plus en plus imprévisible. "Les choses sont plus erratiques que ce que nous pensions, et cela signifie que nos prévisions futures pourraient être largement erronées," conclut-il. Une incertitude qui pousse à repenser nos modèles climatiques pour mieux anticiper les défis à venir. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.
Hello Interactors,Flying provides a great opportunity to catch up on books and podcasts, but it also brings feelings of guilt. My recent trip likely contributed about 136 hot air balloons' worth of CO2 to the atmosphere. Should I feel guilty, or should the responsibility lie with airlines, manufacturers, and oil companies? We all contribute to global warming, but at least our destination was experiencing an unusually cool July. However, globally, the situation is very different and worsening faster than expected. What's to be done? Let's dig in.CLIMATE CONUNDRUMS CONFOUND CALCULATIONSThere are two spots on the planet that are not affected by climate change, and I recently flew over one of them. It's a patch in the ocean just off the coast of Greenland that our plane happened to fly over on a family vacation to Scotland. The other is a small band around the Southern Ocean near Antarctica. I likely won't be visiting that one.I learned this on the plane listening to a podcast interview by the physicist Sean Carroll with climate scientist and Director of NASA's Goddard Institute for Space Studies, Gavin Schmidt. Gavin has been at the forefront of climate science, spearheading efforts to quantify Earth's climatic fluctuations, develop sophisticated models for projecting future climate scenarios, and effectively communicate these findings to the public and policymakers.In this discussion, they talked about the methods currently employed in climate research, while also offering insights into the anticipated climatic shifts and their potential impacts in the coming decades. Gavin is known for bridging gaps between complex science and accessible information. I'm writing this piece to bridge some of my own gaps.For example, there's often mention that climate change has created more extreme swings in temperature — that the weather is increasingly varying from extreme heat to extreme cold. In statistics, this is called variance. Some argue this variance may be hard for us to detect because temperatures have been shifting — a phenomenon known as shifting baseline syndrome.Gavin says there's more to this question than people realize. He notes that it is relatively straightforward to detect changes in the mean temperature because of the law of large numbers. Temperature varies across three dimensions - latitude, longitude, and altitude. We can calculate an average temperature for any two-dimensional slice of this 3D space, resulting in a single representative value for that area.This video is a conceptual simulation showing a 3D volume of temperature readings (warmer toward the ground and cool toward the sky). The 2D plane ‘slices' the cube averaging the values as it encounters them and colors itself accordingly. Source: Author using P5.js with much help from OpenAI.With enough data, it's clear that there has been a significant warming trend almost everywhere on Earth since the 1970s. Approximately 98% of the planet has experienced detectable warming, with a couple exceptions like the ones I mentioned.But determining changes in the variance or spread of temperatures is more complex. Calculating variance requires a comprehensive understanding of the entire distribution of data, which requires a larger dataset to achieve statistical confidence. Schmidt points out that while we have enough data to confirm that the distribution of temperatures has shifted (indicating a change in the mean), we do not yet have sufficient data to conclusively state that the variance has increased.Recent temperature spikes tell this story well. For the last decade or more, many climate scientists have been confident in predicting increased global mean temperatures by looking at past temperatures. The global mean has been predictably increasing within known variances. But in 2023 their confidence was shaken. He said,“Perhaps we get a little bit complacent. Perhaps we then say, 'Okay, well, you know, we know everything.' And for the last 10 years or so, [that's been] on the back of both those long-term trends, which we understand…”He goes on to explain that they've been able to adjust temperature predictions based on past trends and the cyclical variances of El Nino and La Nina. Scientists have boldly claimed,“'Okay, well, it's gonna be a little bit cooler. It's gonna be a little warmer, but the trends are gonna be up. You know, here's the chance of a new record temperature.' And for 10 years that worked out nicely until last year. Last year, it was a total bust, total bust like way outside any of the uncertainties that you would add into such a prediction.”How far outside of known uncertainties? He said,“…we were way off. And we still don't know why. And that's a little disquieting.” He added, “…we ended up with records at the end of last year, August, September, October, November, that were, like they were off the charts, but then they were off the charts in how much they were off the charts. So, they were breaking the records where they were breaking the records by a record-breaking amount as well. So that's record breaking squared, if you like, the second order record breaking. And we don't really have a good answer for that yet.”There is ongoing research into why and some have speculated, but none of them add up.For example, we're currently nearing a solar maximum in the sun's 11-year cycle which increases solar irradiance, but that small increase doesn't fully explain the observed changes. Other factors may be at play. For instance, there have been significant shifts in pollution levels in China, and the shipping industry has transitioned to cleaner fuels, which, as hoped, could be influencing climate patterns.However, Schmidt notes that the quantitative analysis of these factors hasn't yet matched the observed changes. Identifying potential contributors to climate variations is one thing, but precisely quantifying their impacts remains a challenge. Schmidt said climate and planetary scientists hope to convene in December to share and learn more, but the extreme shift remains concerning.CALCULATING CLIMATE'S COUNTLESS COMPONENTSThe amount of data required to model the climate is daunting. In a separate TED talk, Schmidt reveals that understanding climate change requires considering variables that span 14 orders of magnitude, from the microscopic level (e.g., aerosols) to the planetary scale (e.g., atmospheric circulation). These accordingly have their own orders of magnitude on a time scale, from milliseconds of chemical reactions to weather events over days or weeks to long term changes over millennia, like ice ages or long-term carbon cycles.Climate models must integrate processes across these scales to accurately simulate climate dynamics. Early models could only handle a few orders of magnitude, but modern models have significantly expanded this range, incorporating more detailed processes and interactions.Schmidt highlights that climate models reveal emergent properties—patterns that arise from the interactions of smaller-scale processes. For instance, no specific code dictates the formation of cyclones or the wiggles in ocean currents; these phenomena emerge naturally from the model's equations.But there is a staggering amount of data to model. And it all starts with the sun.The sun provides 99% of the Earth's energy, primarily in the visible spectrum, with components in the near-infrared and UV. This energy interacts with the atmosphere, which contains water vapor, greenhouse gases, ozone, clouds, and particles that absorb, reflect, or scatter light.The energy undergoes photolytic reactions. Photolytic reactions are chemical reactions that are initiated or driven by the absorption of light energy which breakdown molecules into smaller units. We couldn't breathe without it. The earth's ozone is decomposed into oxygen in the atmosphere through these reactions, which is initiated by sunlight — especially in the stratosphere. This too must be tracked as the Earth rotates, affecting sunlight exposure.Upon reaching the ground, some sunlight is reflected, by snow for example, or absorbed by oceans and land. This influences temperatures which is then radiated back as infrared energy. This process involves complex interactions with clouds, particles, and greenhouse gases, creating temperature gradients that drive winds and atmospheric motion. These dynamics further affect surface fluxes, water vapor, cloud formation, and associated chemistry, making the entire system highly intricate. And this doesn't even remotely begin to approach the complexity of it all.To simplify Schmidt says they capture what they can in a column roughly 25 kilometers high and wide to study the inherent physics. Most of which he says,“…is just vertical. So, the radiation you can think of as just being a vertical process, to very good order. Convection is also just a vertical process. So, there's a lot of things that you can do in the column that allows you to be quite efficient about how you solve the equations.” Schmidt adds that “each column [can] sit on a different processor, and so you can do lots of things at the same time, and then they interact via the winds and the waves and those kinds of things.”He said most of the calculations come down to these two sets of equations: Euler and Navier-Stokes. Euler equations are a set of partial differential equations in fluid dynamics that describe the flow of non-viscous and fluids, absent heat exchange. Named after the Swiss mathematician and physicist Leonhard Euler in the 18th century, these simplify the analysis of fluid flow by neglecting viscosity and thermal conductivity, focusing instead on the conservation of mass, momentum, and energy.Navier-Stokes, named after the 19th century French civil engineer Claude-Louis Navier and the Irish physicist George Gabriel Stokes, is based on Euler's work but adds viscosity back into the equation. Schmidt says these equations are sometimes used to measure flows closer to the surface of the earth.This video is a conceptual simulation showing a 3D volume of vectors (randomly changing direction and magnitude) with particles entering the field of vectors. Each particle (e.g. dust, rain, aerosol) gets pushed in the direction of the vector each encounters. You can clearly see the emergent swarming behavior complex adaptive systems, like our atmosphere, can yield. Also present are the apparent challenges that come with measuring and predicting these outcomes. Source: Author using P5.js with much help from OpenAI.These complex computational models are inherently approximations. They are validated against observations but remain simplifications of reality. This inherent uncertainty is a critical aspect of climate science, emphasizing the need for continuous refinement and validation of models.And while human-induce climate change denialists like to say the climate models are wrong and not worth considering, Schmidt has a clever retort,“Models are not right or wrong; they are always wrong, but they are useful.”NAVIGATING NATURE'S NEW NORMALMany wish climate change predictions had the kind of certainty that comes with basic laws of physics. While there are indeed efforts in complexity science to identify such laws, we're still in the foothills of discovery on a steep climb to certainty.For example, to even achieve the current level of climate prediction took approximately 30 years of research, involving multiple methods, replication, and more sophisticated physical modeling. This led to accurate calibration techniques for the paleothermometers that measure ice cores which reveal temperatures from around the planet dating back three million years.While there is some empirical certainty in this — derived from the periodic table, fundamental laws of physics, or observed correlations from spatially dispersed ice core samples — recent extreme variations in global temperatures give reason to question this certainty. These relationships were based on spatial variations observable today, but failed to account for change over time, which behave very differently.Schmidt says, “…it turns out that the things that cause things to change in time are not the same things that cause them to change in space. And so empirical relationships that are derived from data that's available rather than the data that you need can indeed lead you astray.”It begs the question: how far astray are we?We know over the last one hundred years or so the planet has warmed roughly an average of 1.5 degrees Celsius. This is a number that has been contorted in the media to mean some kind of threshold after which “something” “might” happen. But Schmidt cautions there is no way to know when we hit this number, exactly, and it's not going to be obvious. Perhaps it already pushed passed this threshold, or it may not for another decade.He says, “we are going to continue to warm on the aggregates because we are continuing to put carbon dioxide and other greenhouse gases into the atmosphere. Until we get effectively to net zero, so no more addition of carbon dioxide to the atmosphere, temperatures will continue to climb. The less we put in, the slower that will be. But effectively, our best estimate of when global warming will stop is when we get to net zero.”Getting to net zero involves significant and radical changes in energy production, industrial processes, and consumption patterns. Moreover, it will require an unprecedented comprehensive and coordinated worldwide effort across all sectors of the economy, institutions, and governments.This is true even for hypothetical and speculative climate engineering solutions like injecting sulfates into the atmosphere in attempts to cool the planet. According to Schmidt, not only would this require cooperation across borders, so long as we keep spewing emissions into the atmosphere, we'd be forever trying to cool the planet…for eternity or at least until we've exhausted all the planet's fossil fuels.It's hard to imagine this happening in my lifetime, if ever. After all, climate change is already disrupting and displacing entire populations and we're seeing governments, and their citizens, becoming increasingly selfish and isolationist, not collaborative.As Schmidt admits, “We're not on the optimum path. We're not on the path that will prevent further damage and prevent the need for further adaptation. So, we're going to have to be building climate resilience, we're going to have to be adapting, we're going to have to be mitigating, and you have to do all three. You can't adapt to an ever-getting-worse situation, it has to at some point stabilize.”Schmidt says he derives no joy in telling people “that the next decade is going to be warmer than the last decade and it was warmer than the decade before that.” He says, “It gives me no joy to tell people that, oh yeah, we're going to have another record-breaking year this year, next year, whenever. Because I'm not a sociopath. I'm a scientist, yes, but I'm also a person.”Schmidt's words resonate deeply, reminding us that behind the data and predictions are real people—scientists, citizens, and future generations—all grappling with the weight of our changing world. As we stand at this critical juncture, we're not just passive observers but active participants in Earth's unfolding story, a story that's leaving its mark on nearly every corner of our planet.The butterfly effect, as meteorologist Edward Lorenz proposed, isn't just about tornados in Texas being set off by a chain of events from the flap of a butterfly's wings in Brazil; it's a powerful metaphor for our collective impact. Each of us, in our daily choices and actions, creates ripples that extend far beyond our immediate sphere. In a world where only two small patches—one off Greenland's coast and another near Antarctica—remain untouched by climate change, our individual actions carry profound significance.The path to net zero isn't just about grand gestures or technological breakthroughs. It's about millions of small, intentional actions coalescing into a force powerful enough to alter our trajectory. As we face the challenges ahead, let's remember that our individual agency, when combined, has the potential to create tsunamis of change, even in places we may never visit ourselves.In the end, it's not just about preserving a habitable planet — it's about preserving our humanity, our connection to each other and to the Earth that sustains us. As we navigate this critical decade and beyond, let's carry with us the knowledge that every action, no matter how small, contributes to the larger narrative of our planet's future. We are all butterflies, and in a world where climate change-free zones are becoming as rare as a family vacation to Antarctica, our wings have never mattered more. This is a public episode.

This has been a year of record temperatures across the globe. According to the US National Oceanic and Atmospheric Administration (NOAA), June 2024 was the warmest June on record and the 13th consecutive month of record-high temperatures. This follows news from the Copernicus Climate Change Service that we recently experienced a 12-month period in which every month was at least 1.5 degrees Celsius higher than pre-industrial temperatures. That's significant not just because it felt a little hotter for all of us, but because climate scientists have identified 1.5 degrees Celsius as a critical global warming threshold to avoid the worst impacts of climate change. To be clear, this doesn't mean the fight against climate change is lost. But the extreme heat impacting billions of people this summer is providing a preview of what might lie ahead if we don't take aggressive action. Today's episode features a conversation with Dr. Stephanie Roe, WWF's Global Climate and Energy Lead Scientist. Stephanie explains the role that climate change plays in driving heat waves (2:02), what key indicators she's following to determine just how bad heat-related climate impacts have gotten (5:18), and what we can all do in our daily lives to address climate change and adapt to extreme heat (14:05).

Prospect contributing editor Isabel Hilton is joined by Margot Wallström, a former Swedish foreign affairs minister and head of the High-Level Working Group on the Environmental Consequences of the War in Ukraine. They discuss the environmental damage Russia's war has caused in Chernobyl and across the country. Also on the podcast, climate scientist Gavin Schmidt discusses the worrying news that climate models can't explain 2023's historic temperature high. Hosted on Acast. See acast.com/privacy for more information.
Gavin Schmidt is Director of the NASA Goddard Institute for Space Studies. He tells us “Climate models can't explain 2023's huge heat anomaly – we could be in uncharted territory.” Meanwhile, so much ice is melting at the Poles, Earth's rotation is changing. …
As the saying goes, history often repeats itself. Could that also hold true when looking at the current state of the climate and where we may be heading? On this episode, the team talks with Dr. Michael Mann, the director of the University of Pennsylvania Center for Science, Sustainability, and the Media and one of the world's leading experts on climate change.

I'm, meteorologist Sean Sublette, and welcome to Across the Sky, our national Lee Enterprises weather podcast. Lee Enterprises has print and digital operations in more than 70 locations across the country, including in my home base in Richmond, Virginia. I'm joined by my colleagues from across the sky, Matt Holiner in Chicago, and Joe Martucci at the Jersey Shore. Kirsten Lang is out this week. Our very special guest this week is Dr. Michael Mann, director of the University of Pennsylvania Center for Science, Sustainability, and the Media, and the Presidential Distinguished Professor of Earth and Environmental Science. His latest book came out a couple of weeks ago called Our Fragile Moment. It goes through Earth's climate history to illustrate how we know what the current warming climate is without precedent in Earth's history. There is so much good stuff in this book. I could go on and on, but I really like the way he goes into paleo climate and helping us understand why we are at this moment in time and why he calls it Our Fragile Moment. And as a quick aside, in the book, he kind of alludes to, the police, the band The Police, and the, extinction of the dinosaurs and walking in your footsteps. So those of us of a certain age who remember that a good part of, you know, sting was the lead man of the police, and, Fragile was another song that Sting wrote. So this all kind of ties back into me. Here I am showing my age. but, guys, this is such a great conversation. What did you kind of take out of this? Joe Martucci: I think, you know, and just take a step back. I mean, Mike Mann is, I would say, one of the people who really put climate science on the map to the general public. So this is really a big interview that we have here. And, when you're listening, sometimes we're getting into the weeds, sometimes it's big philosophical questions. In fact, at the end, we talk about his thoughts on where our position as the human race is in the universe just by writing this book. So, it was a nice interview, and good to be with, Mike here. Matt Holiner: Yes, there are few people that are a bigger expert on climate change than Mike Mann. And so, yeah, we're honored to have him on the podcast. And what I like is how he talks about paleo climate, which is something that's starting to get a little bit of buzz now. I think everybody's accepted that, okay, the climate is changing now, but hasn't it changed in the past? And he does dive into that. Yes, it has changed, but what he points out is the change that we're undergoing right now is unique, and he. Joe Martucci: Points out why that is. Matt Holiner: And I really liked his discussion of that. Sean Sublette: Yeah, there is so much good stuff. So let's get right to it and start up with our interview with Dr. Michael Mann. Mike Mann, it is so good to have you on the across the sky podcast. Dr. Michael Mann writes a new book about climate change called ‘Our Fragile Moment' Sean Sublette: I want to jump right into this on this book, Our Fragile Moment. This is the 6th book. What I loved about this one is that it goes a lot deeper into understanding paleo climatology. For us real science geeks out there, it really gets into depth about how we know how we got to this fragile moment. So I wanted to start on the big picture. What motivated you to write this book now? Dr. Michael Mann: Yeah. Thanks, Sean. It's great to be with all of you. All three of you know, it's interesting, this is sort of where I got my start as, a climate scientist, Paleo Climate, the hockey stick curve that my co authors and I published. it's hard to believe now, but it's, two and a half decades ago, that graph became sort of this iconic symbol, in the climate change debate. And that's really how I sort of entered the fray. And so now, two and a half decades later, I decided, well, let's do a deeper dive, because the hockey stick only went back a thousand years. That's really shallow time, as we say in Paleo climate. We've got four plus billion years of Earth history to look at and let's see what we can learn from it. And so it's sort of a return to my roots, in a sense. I hadn't really written a book about paleo climate, even though it's where I started as a scientist. And there's another sort of driving force here as well, which, relates to my last book, The New Climate War, which is about sort of the challenges we face now as climate denial becomes almost untenable, because we can all sort of see the impacts of climate change playing out. Bad actors are using misinformation to delay transition off fossil fuels Dr. Michael Mann: But there are other tactics that bad actors are using to sort of delay the transition off fossil fuels. and one of them, ironically, is doom mongering. If they can convince us that it's too late to do anything about the problem, then why bother? And so I was seeing Paleo Climate, something that I hold dear. I was seeing paleo climate science. Weaponized. Now in the same way that climate deniers used to weaponize misinformation. I was seeing climate doomers weaponizing misinformation about paleo climate to convince us it's too late, that we're experiencing runaway warming. We are going to it's yet, another mass, extinction that we've set off that's unstoppable and we will all be gone in less than ten years. There were players out there, serious protagonists who have pretty large followings, who have been spreading that sort of misinformation. So I decided, let's reclaim paleo climate. Let's look at what the science actually says. And that was the purpose of the book initially, was to address some of those misconceptions that have been used to feed climate doomism. But in the process, I realized, well, no, there's a whole lot more to talk about. there are all sorts of lessons in 4 billion plus years of Earth history. Let's see what we can learn from it for sure. Sean Sublette: Before I turn it over to the other guys for questions, I want to talk a little bit more about that doomism concept. It's important to walk a line between urgency and agency, as you like to talk about, but get away from doomism. I'd like to point out I was actually talking to a Rotary Club earlier today, that there has been progress. Right. clearly there needs to be more, but I like to point out we're starting to phase out coal globally. So there are things going how do you walk that line in terms of this is important, we need to stay on it, showing that there's progress and not succumbing to doomism for folks who are kind of depressed about it. Dr. Michael Mann: Yeah, no, absolutely. And there's sort of two pieces to it. First of all, there is just the science. Like, does the science say that we've triggered unstoppable warming and nothing we do to reduce carbon emissions is going to make a difference? No, it doesn't. And I wanted to make that very clear. And no, the paleo climate record doesn't support that. the best available science, in fact, tells us now that the planet stops warming up when we stop adding carbon pollution to the atmosphere. So there's this direct and immediate impact, on the climate of our efforts to act here. There's another piece to it, though, which is sort of there's another sort of component to doismism, which is like, we're not going to get our act together. And you could argue that remains to be seen, that's at least Arguable, the science doesn't support runaway warming. It doesn't support that sort of side of doomism. But will we garner the will to tackle this problem? Only the, future will tell. But it's interesting because you mentioned Rotary Club. There are lots of reasons for optimism. Lots of reasons. Things that we can look at, where we can say we're making real progress, rotarians have really taken a leadership role on this issue. I've spoken to some Rotary Clubs, groups in the past, and the Youth Climate movement, right. I mean, just, there is all of this energy. I see. know I teach at the University Of Pennsylvania. Climate is probably the number one issue to these students today, to these gen zers. Now, some of them fall victim to climate anxiety and climate doomism. So it's really important for them to understand the agency part of that urgency and agency duality. But yeah, the science certainly doesn't support the notion that we can't do something about the climate crisis. And the paleo climate record certainly doesn't support that either. Joe Martucci: Hey, this is Joe and just want to thank you so much for coming on again. We really appreciate it. And best of luck to you and your, book here, Our Fragile Moment. More journalists are reporting on extreme weather events linked to climate change Joe Martucci: My question does partially relate to what you said about gen zers. And some people do have climate anxiety. And if you're young, you're impressionable you're getting content from a variety of different sources, right? More than ever before, when we talk about extreme weather events and parlaying this into climate change. Right. I feel like in the past five years, maybe three years, we've seen a lot of this recently. And I think, personally, from my perspective, it's good. It's always a good teaching moment to talk about the facts and to forecast the climate science. How do you feel, though, about journalists reporting on this, as opposed to meteorologists who are experts in their field? There's many great journalists all across the country. We know that. But just like I don't know everything about maybe astronomy, right. Journals may not be completely in sync with what's happening with some of these events. Dr. Michael Mann: I don't know if you could kind. Joe Martucci: Of give us where you fall on this and how you would like to see these extreme weather events being parlayed into coverage as we go forward. Dr. Michael Mann: Thanks, Joe. It's a great question. And, you were talking about young folks, and, I used to think of myself as a young person, and then today I realized that David Lee Roth is 69 years old. I finally forced to accept the fact that I am now old. But you're right, there is this, energy and passion, among young folks. And another part of what's going on is we're seeing the impacts of climate change now play out in a profound way in the form of these extreme weather events. And there's always sort of this delicate balance in the way we cover those events. You'll often hear people say, well, you can never blame any one, weather event, on climate change. and the thinking there has evolved quite a bit. We have detection and attribution. We can characterize how likely an event was to occur in the absence of climate change and how likely it was to occur. When we consider climate change and when we see that there's a huge increase when an event is a thousand year event without climate change, and it's suddenly a ten year event when we include climate change, then we can say, hey, the fact that we saw this is probably because we've warmed up the planet and we've made these sorts of events, these extreme heat waves, heat domes that we've been reading about, wildfires floods, superstorms. So there's this scientific machinery now that allows us to sort of characterize the impact that climate change is having on these events. But you're right. When you have trained meteorologists and climate experts who are familiar with that science, they're able to sort of frame it that way. When you have just sort of say, political journalists, journalists from other fields covering, the science, it's a quandary. It's very complicated because they're hearing conflicting things. They're hearing this. You can never blame any one event on climate change, but now they know that there is a way to try to characterize the impact that climate change is having. So I think there's some confusion among in the journalistic community right now. you also sometimes see it overplayed, right, where, like, every extreme event was caused by climate change. We can't say that it's like a loading of the dice. Sixes are going to come up anyways. The fact that they're coming up so often is because we've loaded those dice, by the warming of the planet. So it is a complicated topic, and it's difficult to even trained climate and meteorology, specialists, even for us, it can be sort of challenging to explain the science and how we're able to quantify the impact climate change is having on these events. And that means that it often gets very confused in the public discourse. And at the same time, I would say that we are seeing the signal of climate change now emerge from the noise in the form of these extreme weather events. And it's a lost opportunity for certain if we don't explain that to the public. And so I personally think that there has been sort of a shift towards journalists in general, recognizing that there is a relationship and mentioning that when they talk about these events, not as often as we might like them to do, but we do see much more of that now. Climate change is part of the conversation here. And that's a real game changer, because that's where the rubber hits the road. When people realize, oh, man, it's these devastating fires. I have a friend who lost a house, or I have people, I know who got flooded, by that storm. When people start to know people who have been impacted or who have been impacted themselves, when people have their own climate story to tell, it really changes the whole conversation. And I think we're seeing that shift. Matt Holiner: Hey, Mike, it's Matt, and I think you're right about the climate change just becoming a term that everyone is familiar with now. But I think the term that people aren't as familiar with that. Matt Holiner: You mentioned your book is Paleo climate. So when you're talking about paleo climate, how far back are you looking and what are you looking at to determine what the climate was thousands or millions of years ago? Dr. Michael Mann: So it's a matter of perspective, right? If you ask my daughter what's paleo climate LBO is like, those winters when you were growing up, that's paleo climate, to me, those 1970s winters. so it's always a matter of perspective. One person's paleo climate is another person's sort of recent, climate history. I focused a lot of my early work on the last thousand years where we could pull together all sorts of types of information to try to reconstruct in some detail how the climate had changed. but there are ways to go much further back. There are sediment cores. We can look at ancient, oxygen isotopes and reconstruct what ocean temperatures were and what, sea, levels were. so there's all of this wealth of information. And so what paleo climate really means, technically, it's anything that predates the historical era of the last couple of centuries where we actually have thermometer measurements or rain gauges measurements or what have you. Anything farther back than that, where we have to turn to indirect measures of climate like tree rings or corals or ice that becomes paleo climate. And so 1000 years that's paleoclimate. But a million years is paleoclimate and a billion years is paleoclimate. And the stories are so different on these different timescales. And the puzzles are all different. And each of these intervals, there are all of these events in Earth's climate history that I talk about in the book, and we can learn something from each of them. Snowball Earth. Yes, the Earth was once entirely covered in ice and unpacking. That tells us a lot about the dynamics of the climate system. the faint early sun. The great Carl Sagan recognized that the Earth should have been frozen 4 billion years ago, when life first emerged in the oceans. And we know it wasn't because there was liquid water, there was life. And he realized because the sun was only about 70% as bright back then, the Earth should have been frozen, but it wasn't. What, what's the explanation? How come there was an even stronger greenhouse effect? And it turns out that, gets us into sort of the Gaia hypothesis because there's this remarkable story where as the sun gradually gets brighter and the Earth should have got hotter and hotter, but it didn't because the greenhouse effect got weaker over time. And in just such a way that the planet's climate, with some exceptions, like snowball Earth, stayed within habitable bounds, within bounds, that are habitable for life. Why is that? that's a really interesting puzzle. And it turns out life itself plays a role in stabilizing the climate, the global carbon cycle, the oxygenation of the atmosphere. There are all of these things that life itself did to change the composition of our atmosphere and to change the dynamics of the planet. And amazingly, life works in such a way as to help keep the climate, Earth's climate, habitable for life. And so that's an interesting puzzle. There's a lot to learn from that as well. And that's a good thing, right? There are stabilizing factors within the climate system that helps us. There is a certain amount of resilience. And that's one of the arguments against doomism that we're getting some help from the behavior of Earth's climate. There's a m safety margin. There's a margin, where we can perturb the climate, and it will stay within habitable bounds. The problem and what makes this such a fragile moment is we're now sort of at the edge of that envelope of stability. And if we continue with business as usual, we continue to pollute the atmosphere with carbon pollution, we will leave that moment behind. We, will depart from the sort of climate upon which all of this societal infrastructure was built to support now a global population of more than 8 billion people. And that's the real threat today. Sean Sublette: All right, so we're going to take a quick break. We'll come back with a couple more key questions with Michael Mann on the across the sky podcast. Stay with us. Michael Mann talks about the chemistry that helps us reconstruct past climate Sean Sublette: And we're back with Dr. Michael Mann on the across the sky podcast. The new book is our fragile moment. It is a very deep dive, as they say, into paleo climatology, and why this particular moment in time is so crucial in the climate going forward. Mike, your expertise, obviously, is in paleo climates and all these things that we use geologically to reconstruct climate. A lot of us are familiar with the ice cores. also, these oxygen isotopes, those for the weather folks, are not quite as complicated. But, what I'd like to talk about a little bit, explain some of the chemistry that's involved, that help us tell us what the climate was like. When we look at ocean sediment cores, these are things that aren't classic atmospheric proxies, right? These are much more in the rocks, geological proxies, those stalagmites, stalactites, those kinds of things. Can you talk about what are we doing with these things in terms of chemistry that tell us what we need to know? Dr. Michael Mann: Yeah, so it's amazing. There are these paleothermometers, we sometimes, call them, and you think about ice, right? Ice is frozen water. That's h 20. And so there's an O in there. There's oxygen, atoms, in that ice. And it turns out that the ratio of heavy to light isotopes of oxygen there are two main stable isotopes of oxygen oxygen 16 and oxygen 18. And the ratio, of them is a function of, the temperature. And when you form precipitation, when you condense water vapor into a droplet, there is what we call fractionation, where the heavy and the light isotopes behave differently during that process. That's true for evaporation, it's true for condensation. And so if you think about what's going on an ice core, you're drilling down in the ice, and that ice got there because it snowed at some point. And that snow was condensation of water vapor in the atmosphere. And that water vapor originally came from the evaporation from the ocean surface. And so at each stage, we have what's called a fractionation, where you're getting some sort of separation between the behavior of oxygen 16 and oxygen 18. The bottom line is, because of that, we can say things about ancient sea level from oxygen isotopes in sediment cores. We can say something about temperature from oxygen isotopes in sediment cores. We can say something about temperature from ice in ice cores on land. And it isn't just oxygen. We can look at carbon isotopes because there's carbon twelve and carbon 13, two different stable isotopes of carbon. And that allows us, for example, to figure out, what happened with carbon dioxide, and what happened with ocean acidification, how much CO2 there was, dissolved in the ocean. In fact, if you really want to get into it, we can estimate the PH of the ocean from other isotopes, boron isotopes. And I'm not going to get into the chemistry of that. But the bottom line is there are all of these amazing we call them proxy data. It's almost like nature provided us a way to sort of solve this puzzle of what happened in distant past. Almost like we were given, clues. It's like, well, I'm going to give you these isotopes, and if you're smart, and if you figure out the chemistry and the physics, you will be able to figure out what happened to sea level, what happened to ocean temperatures, what happened to the amount of ice, what happened to the acidity of the ocean. All of these things that are very relevant to how carbon pollution is impacting our environment today. Matt Holiner: And Mike, I think we've reached a point now where everybody acknowledges that the climate is changing. It took us a long time to get here, but I think we've reached that point. But what people are pointing out now is that, as you're talking about with paleo climate, the Earth's climate has changed many times over the years, warming and cooling. So what makes the climate change that we're experiencing now unique compared to the past? Dr. Michael Mann: Yeah, it's a great question, because we can certainly find times in the distant past when carbon dioxide levels, greenhouse gas levels, carbon dioxide being the main sort of greenhouse, gas that varies over time. They were higher than they are today, and global temperatures were warmer than they are today. During the Early Cretaceous Period, dinosaurs were wandering the polar regions of the planet. There was no ice on, the face of the Earth. We've seen Earth go from ice covered to ice free. So we know there are times when it's been much colder than today. And there are times when it's been considerably warmer than today. So then the question is, all right, well, then what makes climate change such a problem? Because even if we warm the planet, with carbon pollution, we're not going to get up to those Early Cretaceous levels. Well, actually, if we tried really hard, we could. If we extracted every bit of fossil fuels we could find, we could do that. Why? Because all of that carbon that was in the atmosphere slowly got deposited beneath the surface of the Earth in what we today call fossil fuels, ancient carbon, organic carbon that got buried in soils or shells that fell to the bottom of the ocean. Carbon that was in the atmosphere, got buried beneath the surface of the planet and came down from those very high early Cretaceous levels, over 100 million years. Due to those natural processes, carbon dioxide levels came down. Well, what we're doing now is we're taking all that carbon that got buried over 100 million years beneath the surface and we're putting it back into the atmosphere, but we're doing it a million times faster. We're taking carbon that was buried over 100 million years and we're putting it back up in the atmosphere over 100 years. And so I sometimes say if I was going to write a slogan for this, it would be, it's the rate, stupid. We all remember, it's the economy, stupid. I think we're old enough some of us are old enough to remember that was sort of a political sort of logo. Well, it's the rate, stupid. Which is to say it's not so much how warm the planet is or, what the CO2 levels are. It's what climate are you adapted to and how rapidly are you moving away from that climate. Because we have developed this massive societal infrastructure over a 6000 year period. Civilization, I talk about sort of the origins of civilization in Mesopotamia, 6000 years was the first true civilization. And it turns out global temperatures were remarkably stable for six, seven, 8000 years during which we developed all of this infrastructure that supports eight plus billion people. And we are dependent on the stability of that climate and its ability to continue to support that infrastructure which we've created. And if we're rapidly changing the climate and moving out of that window of variability during which we created civilization, that's a real threat. If the warming exceeds our adaptive capacity and it exceeds the adaptive capacity of other living things, life has learned to adapt to, climate changes that take place over tens of millions of years. That's pretty easy. Adapting to climate changes of similar magnitude that take place over tens of years, that's much more difficult. And again, what makes it so fragile, such a fragile moment for us is that we have leveraged the number of people who can live on this planet, what we call the carrying capacity of the planet. We've probably leveraged it by a factor of ten. Through our technology, through our infrastructure. We can support eight plus billion people because we have all of this infrastructure, agricultural infrastructure, engineering. But it's fragile, right? Because if the planet warms dramatically and that infrastructure no longer remains viable, then we can no longer support that elevated carrying capacity. Then we revert to the natural carrying capacity of the planet, which is maybe a billion people. And you think about that. The planet without our infrastructure, without our technology, probably can't support more than a billion people. We've got more than 8 billion people. That's why we can't afford to destabilize the infrastructure that supports human civilization today. And that's what dramatic warming, that's what unmitigated climate change will do. How does studying Paleo climatology make you see our place in the universe? Joe Martucci: John said, I had the last question here, so I'll wrap up with this. how does studying Paleo climatology and maybe even writing this book make you see our space or our race as humans in this universe? Because a lot of what you're talking about, you said Fragile Rights, the name of the book. How do you see our place in the universe, given what you've studied over the decade? Dr. Michael Mann: Thanks. It's a great question. and it's something I get into a little bit. Have some fun. At one point, we do some thought experiments. Some thought experiments, like, what if in one of the chapters, which is on, an episode of rapid warming, and by rapid warming, we mean, like, over 10,000 or 20,000 years rapid on geological timescales. Nothing like what we're doing today. But there was this period of relatively rapid warming, about 56 million years ago. We call it the PETM. Stands for the Paleocene eocene thermal maximum. It just rolls right off the tongue. And it was this period during which there was a massive injection of carbon dioxide into the system. Obviously, there weren't SUVs, and there weren't coal fired power plants. This was a natural input of volcanism through unusually intense volcanic eruptions, centered in Iceland, that tapped into a very carbon rich reservoir and put a very large amount of carbon dioxide into the atmosphere over a relatively short period of time. And so it turns out that you can ask the question, can we rule out the possibility that there was an intelligent civilization back then that went on this massive fossil fuel burning spree and basically extinguished themselves? And my good friend Gavin Schmidt, who's the director of the NASA Goddard Institute for Space Studies, has written a paper and has written some popular, essays about this idea because of the Silurian hypothesis. and it's basically imagine lizard people who existed 56 million. How can we rule out that that's what happened? And I grew up watching the land of the lost. And, Gavin, around the same time he was in Britain, and I think it was Dr who had a similar that's where the Silurian there were, like, these reptile beings, that basically destroyed their environment. And so it's a really interesting question. Can we rule that out? And in the process of trying to rule that out, it actually raises some really interesting questions about, what are the conditions for life? Do intelligent civilizations extinguish themselves naturally? this is sometimes called the Fermi paradox. it was something that Carl Sagan thought about if the universe is teeming. With life? How come we're not hearing from them? How come we're not getting radio signals? And it turns out you can look at all of the different how many planetary systems are there in the universe? You can sort of try to do the math and figure out how many intelligent civilizations you might expect there to be in the universe based on various assumptions. And it turns out the defining problem, all the uncertainty comes down to when intelligent civilizations emerge, how long do they persist for? Do they extinguish themselves? And that would be one explanation of Fermi's paradox. Obviously, it's very personal to us. We don't want to think that, we are on our own way to self caused extinction. So there's some deep questions there. When you look at Paleo Climate and you look at some of these past episodes, you can start to ask some larger questions that tap into these deeper philosophical questions about our place in the universe. is there life elsewhere in the universe? The thinking that you go through turns out to be very relevant to the thinking that you need to go through for, Know. And the punchline is, Adam. I'm going to draw a blank on his, so, he's a well known astrophysicist, and writes about the search for extraterrestrial life. Adam and I'm drawing a blank on his last name, which is very embarrassing. I'm, sure he'll watch this and be very upset at me. but, he actually came to Gavin because he was interested in the search for extraterrestrial life and asking some questions about climate change and climate change on other planets. and could that explain why we're not hearing from other civilizations? Because they cause climate change and they extinguish themselves. And, Adam Frank is his name, and he's a well known sort of, science communicator, astrophysics search for extraterrestrial, sort of continuing the legacy of Carl Sagan and the Planetary Society and the sorts of questions that they were asking. So he came to Gavin, who's a climate modeler, and know, I want to work on, know, figuring out if climate change could have been what caused these other potential civilizations elsewhere in the universe to extinguish themselves. And then Gavin says, how do we know that that didn't happen on Earth? And they go through this amazing sort of thought experiment, and it turns out it's hard at first blush to rule out that that's what happened. For example, the PETM. It takes quite a bit of work to convince yourself that it couldn't have been ancient lizard people that burned, fossil fuels. and so, yeah, so there's a lot you can learn from what are seemingly silly thought experiments that actually start to get at some pretty deep questions about us and our place in the universe. Sean Sublette: We know not all questions are silly. What plate tectonics has only been around for about 100 years or so. And everybody kind of thought, well, that was silly at the time. Dr. Michael Mann: Mike, we're going to stickers stop plate tectonics bumper stickers. Sean Sublette: Yeah, we're going to let you go. But, again, the book is our fragile moment. Social media is a mess nowadays, but where's the best place people can find you digitally and online? Dr. Michael Mann: Well, they can still find me on, what are we calling it this day? X. that's what it's called this week. But, I've sort of diversified. You can find me pretty much on all of the major social media platforms now. I'm still on Twitter. X, and, Instagram and mastodon and Blue, sky, and I'm forgetting threads. It's like, now we've got to be so diversified because we're no longer confident we can rely on the one that we were all relying on for so long. But, yeah, I'm out there and people can find me at WW Michaelman Net. So, yeah, it was great talking with you guys and I, hope to do so again. Sean Sublette: Mike, appreciate it so much. Take care. travel safely. Good luck promoting the book. and it's great. I mean, I've read it. It's just wonderful. And also, I will say this publicly. Thanks for the little shout out at the back, my friend. Dr. Michael Mann: Thank you, my friend. It was great talking with you guys. Sean Sublette: Those are some very deep answers, guys. where is our place in the universe and this concept of lizard people from 50 OD million years ago. and the things you will go down the road you will go down when you start doing these thought experiments. But for me, the importance here, I think what Mike said is the pace of the warming is without precedent. What we're doing is happening so fast, it is going to be difficult to adapt. Some things are going to adapt more easily than others. And that's why this moment in time is so particular. Yeah, it's been warmer in the past, but our civilization, which is increasingly global over these last 2000, 3000 years in particular, last couple of hundred years, where the population has just blossomed, really kind of dependent on the climate that we have out there now. Guys, what do you think? Joe, what did you kind of take away from? Joe Martucci: Well, you know, anytime we talk about our place in the really, I don't know, just really focused on the topic because it does make you think about in some ways, how small we are relative to everything. And not just even planet Earth and the spec of the universe, but also human life in the span of the Earth's long, long history. And like he also said a few minutes before that question, it's the rate of change of the warming that's unique. I say this a lot of times when I do public talks. I said, listen, yeah, we've been warmer than we've been before, we've been colder than we've been before. But barring like an asteroid or some cataclysmic event, this is the only time we're really changing at such a rate. and there's facts and forecasts, and then there's what to do or not to do about it. And that's where your beliefs come in. But there's no denying that the rate of change, a lot of this is significant and something we haven't seen really in the scope of human history. And beyond that, the Earth's history, again, minus the early millions, billion, two or four years, when the Earth was really trying to just get itself together, for lack of a better word. And in some of these asteroid or supervolcano events, it happened as well. Matt Holiner: I would say this was a humbling conversation, because also at the end, when he was talking about why haven't we encountered other intelligent life? And then the comment that stood out to me is like, maybe it has existed, but because of their actions, resulted in their own extinction, and are we headed down that path? And is that why we haven't encountered intelligent life? And then, the other comment that he made is when he was talking about carrying capacity, and now the Earth has a population of 8 billion. But you take out our technology, and what we could see if we continue on this path, if the climate continues. To the rate the change that it's. Matt Holiner: Experiencing now, that carrying capacity could drop to a billion. And then you think, you think about going from a population of 8 billion people to 1 billion, 7 billion people disappearing. That makes the hair stand your, arms and to think about could we result in our own extinction by our actions? And when you hear that, you want to say, let's not make that mistake, let's do something about this. Because again, the other comment was it's the rate stupid? And he talks about, yes, climate has changed in the past. And that's what some people keep coming out. It's like, well, what's the big deal if the climate has changed the past? We're just going through another cycle, but it's never changed at this pace and. Joe Martucci: We can't keep up. Matt Holiner: He also talked about the planet has taken care of itself. When the sun became stronger, the greenhouse effect decreased. And so there has been that the Earth has all these protections in place to kind of keep the climate in balance. But we're breaking that. We're breaking these natural protections. That's why he calls it our fragile moment. Because if we continue at this pace, the Earth isn't going to be able to heal itself. And so we have to take action to make sure we don't lose 7 billion people. So, again, we don't want to talk about the doomism. So it's a fine balance, though, because we absolutely have to take action, but know that we can take action. This is not hopeless. We still have time to fix this. Problem, so let's get on it. Sean Sublette: Yeah, as he says, there is urgency, but there is also agency. So I think that that's the quote that I like from him, most of all. So as we look to some other episodes coming down the pike, a little bit less heady. coming up next week, we've got Paul James of HGTV. We're going to look at the science of changing leaves. We are thick into, the fall right now, the leaves changing from north to south across the country, and we're also working in the background to bring you a broader winter forecast. We're still turning a couple of knobs on that, but we're working on that. I'll be talking to Neil degrasse Tyson in a few weeks. We'll bring that to the podcast. also I've talked to a couple of colleagues, the fifth national climate assessments coming out, and we're going to say, well, what does that mean and why should we care? We'll answer those questions. we've got one more, Joe. you've got somebody coming in from Ohio State, right? Joe Martucci: Yeah, we do. That's coming up in a couple of weeks. That's for your, November 6 episode. We're speaking with Dr. Lawrence Sutherland, and it's tips prepare older loved ones in case of natural disasters or extreme weather. I've covered this topic a, number of times for the press of Atlantic City, where I'm based out of shout out to everybody listening Jersey, but talking about, some of the challenges our senior citizens are having when there are these kind of extreme weather events. so that should be really good. I'm looking forward to that one, too. And that one comes out on November. Sean Sublette: So we have got a lot of good stuff in the pipeline in the weeks ahead, but for now, we're going to close up shop. So for Joe Martucci at the Jersey Shore. Matt Hollner in Chicagoland. I'm meteorologist Sean Subletz at the Richmond Times dispatch. We'll talk with you next time. Thanks for listening to the across the sky podcast.See omnystudio.com/listener for privacy information.

Welcome to the Harvard Center for International Development's Road to GEM23 Climate & Development podcast. CID's Road to GEM23 series precedes and helps launch CID's Global Empowerment Meeting 2023 (GEM23), Growing in a Green World on May 10th and 11th. At CID, we work across a global network of researchers and practitioners to build, convene, and deploy talent to address the world's most pressing challenges. On our Road to GEM23, we strive to elevate and learn from voices from the countries on the frontlines of the climate crisis and will feature learnings from leading researchers and practitioners working to combat climate change. In this episode, we are joined by Gavin Schmidt, Climatologist and Director of NASA Goddard Institute for Space Studies who will describe the biggest challenges with modeling and predicting climate change effects across the world. CID Student Ambassador and Harvard Graduate Student Yan Liang interviewed Gavin Schmidt to learn more about his insights on the complex mechanisms that drive climate change and identifying and mitigating effects of climate change on society in the coming years.
Dr. Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, discusses current global temperatures, levels of greenhouse gasses and where 2022 ranks in the climate record. Then, Brenda Mann, program director of the University of Utah science and engineering fair, shares fascinating school science and engineering projects.

Science agencies in the US and Europe this week released their temperature data for 2022, revealing what has become an annual headline: Last year was one of the hottest on record. 2022 tied for fifth hottest, according to NASA. The US National Ocean and Atmospheric Administration, which uses slightly different data, said it came in sixth.That's even though La Niña cooled the equatorial Pacific, which typically turns down global temperatures. “This was, in fact, the warmest La Niña year in the whole record,” said Gavin Schmidt, director of NASA's Goddard Institute for Space Studies.Earlier this week, Europe's Copernicus Climate Change Service revealed 2022 was that continent's second-hottest year ever, and hottest summer.Last year was about 2 degrees Fahrenheit hotter than the preindustrial average, or 1.1 or 1.2 degrees Celsius, depending on whose data you use. That's edging closer and closer to 1.5 degrees Celsius, a limit most countries in the world have pledged not to exceed. That goal is written into the 2015 Paris climate change agreement, alongside a less-ambitious target of limiting warming to “well below” 2 degrees Celsius. But it's the lower target that has taken hold in recent years as both a goal and a rallying cry for aggressive climate action. Keeping 1.5 “alive” became the mantra of Alok Sharma, the UK politician who served as president of the COP26 climate summit in Glasgow in late 2021. UN Secretary General António Guterres also frequently references the figure, among many others. A coalition galvanized by low-lying island nations lobbied to get the more-ambitious target written into the Paris climate deal, arguing that exceeding that threshold represented an existential threat for their counties."It means we are dead. Just simply dead," former Maldives President Mohamed Nasheed told The World in 2021. “A whole country gone. A whole people gone. A whole society gone. A whole community gone. And this is the case with many, many low-lying islands.”That target has always been wildly ambitious. But in the last seven years, as carbon emissions have continued to rise, it has gotten even more so. Global greenhouse gas emissions would need to be slashed 45% by the end of this decade to meet it, and a UN report published in October said there was no “credible” pathway to 1.5 in place.Many climate scientists say that they don't believe the target will be met. “I'm pessimistic for the 1.5,” said Thomas Stocker, a climate scientist at the University of Bern who co-led an Intergovernmental Panel on Climate Change report on the physical basis of climate change in the years leading up to the Paris agreement's creation. “We're not on the pathway to actually keep the warming at 1.5 degrees Celsius,” he said. “We [would] be extremely lucky to hold the temperature warming below 2 degrees.”Three scientists involved in tracking the global temperature data that was released this week also said they saw limiting warming to 1.5 degrees Celsius as unlikely. “I think it's very challenging to stay below 1.5,” said Schmidt, saying he was speaking only for himself, not NASA. “My expectation is that we will hit 1.5 degrees sometime in the 2030s,” said Samanath Burgess, deputy director of Europe's Copernicus Climate Change Service.“I think it's very unlikely that we avoid overshooting that level of warming,” said Zeke Hausfather, with Berkeley Earth, an independent research group that also released its 2022 temperature data on Thursday.It's technically still possible to keep warming at 1.5 degrees, according to the science of atmospheric warming. But a recent IPCC report shows it would require a massive shift away from coal, oil and gas at a speed that's hard to imagine. And it almost certainly would require overshooting the 1.5 limit for a time, then removing carbon from the atmosphere again before the end of the century to bring the globe's average temperature back down.Still, Hausfather said he thinks that the goal itself has been useful.“Even if it's a target we don't hit, I feel like the fact that we are trying means we'll probably end up in a better place than if we were aiming higher,” he said.Hausfather points out countries responsible for around 80% of emissions now have targets to reach net-zero emissions by midcentury. Whether they meet them, of course, is an entirely different question, but the goal itself is based on the science behind the 1.5-degree goal. The target being written into an international agreement “holds political leaders accountable,” Burgess said. Even as 1.5 continues to be held up as the goal by political leaders and activists, scientists aren't exactly shouting from the rooftops how much of a stretch it really is.Swiss scientist Thomas Stocker said there's a concern that doing so would stymie ambition.“I disagree,” he said, arguing it should instead galvanize even faster action.“The consequence should be that under no circumstances will we lose the second target and make the same mistakes again.” Some scientists worry that the 1.5-limit has been framed as a kind of tipping point, a make-or-break goal.“The reality is that every single fraction of a degree matters; 1.5 isn't a cliff edge where bad things will happen. Bad things are already happening,” Burgess said.Keeping warming below 1.7 degrees, say, would be better than 1.8 — 1.9 would be better than 2. Each 10th of a degree could cause more extreme rainfall, like the kind flooding California right now, and worsen heat waves, droughts and hurricanes, and further push up sea levels imperiling low-lying island nations. Leaders and activists in those vulnerable countries largely are not ready to talk about a post 1.5-world, at least to reporters. "I can't afford to think that 1.5 degrees is not attainable," former Maldives President Mohamed Nasheed said in 2021. “That would be a death sentence on our countries, and many low lying islands and coastal regions.”With current pledges made under the Paris agreement, the UN Environment Program estimates the world is on track for 2.4 to 2.6 degrees Celsius of warming by century's end.

With a potentially split legislature on the horizon, passing climate policy could become a lot more difficult. We revisit a recent show on one piece of policy President Biden was able to get passed: the Inflation Reduction Act. Andy speaks with public policy expert Leah Stokes, who helped craft The IRA's climate provisions. She explains how the law will transition the economy from fossil fuels to clean energy and get us closer to cutting pollution in half. NASA climatologist Gavin Schmidt tells Andy what actions are needed to prevent further global warming, and how the law could achieve that. Note: This interview was recorded before the Inflation Reduction Act was passed. Keep up with Andy on Twitter @ASlavitt.

The United States is on the brink of passing a climate bill that could get us closer to making real progress against climate change than we've ever been before. Gavin Schmidt, climatologist and director of the NASA Goddard Institute for Space Studies, talks with Andy about the seemingly insurmountable number of climate catastrophes we're currently experiencing and how the the Inflation Reduction Act may help finally rein in climate change. We also hear from Leah Stokes, a political scientist and environmental expert who helped craft some of the bill's climate provisions. She explains how the bill would transition large parts of the economy from fossil fuels to clean energy and get us closer to cutting pollution in half. Keep up with Andy on Twitter @ASlavitt.

We speak with Dr. Gavin Schmidt, climate scientist, director of the Goddard Institute for Space Studies and co-founder of the RealClimate climate science blog. Gavin's research focuses on understanding the past, present and future of the climate system and the impacts of the various drivers of climate change. In this episode we take a deep dive on the science of climate change covering how it is observed, detected and attributed. Along the way Gavin debunks several climate skeptic talking points and discusses the changing challenges of climate communication.Links:Gavin's profile at NASA GISS.The RealClimate blog.The IPCC on humanity's unequivocal influence on the climate.The Oridivician (Not Oligocene) was the geological age that Gavin was referring to.The Smithsonian project to document 500 million years of global-mean temperature (Science).Gavin giving the Stephen Schneider Lecture in 2013: What should a climate scientist advocate for?

The concept of a low-key podcast is strained when Rollie gets on the phone with Dr. Gavin Schmidt, NASA's Senior Climate Advisor to the President. Luckily, Gavin was calling in from an active turkey farm which helped restore the podcast to a calming center. They talk about what an average day is like, the general state of NASA's climate department, the difficulties of juggling, and more. Throughout the episode, Dr. Gavin Schmidt sticks the landing on so many perfect metaphors it almost feels scripted, but if this episode was scripted, don't you think Rollie would have had better jokes? Please enjoy this Sweatpants episode unless you need something high key in which case, keep on walking.
What's the difference between climate and weather? How does NASA monitor changing sea levels, melting glaciers, and other effects of climate change? Gavin Schmidt, NASA's acting senior climate advisor, explains how rising temperatures lead to many complex changes both in the oceans and on land.

Does A Vaccine Help You If You’ve Already Had COVID-19? Vaccines doses have started to rollout and are getting into the arms of people. We know that if you already had COVID-19, you build up antibodies against the virus. So do the vaccines affect you if you’ve already had COVID-19? Science writer Roxanne Khamsi talks about recent studies showing that a single dose of vaccine could boost immunity for former COVID-19 patients. She also discusses a study that found over 140,000 viral species in the human gut and Elizabeth Ann, the first cloned black-footed ferret. The Aftermath Of Texas’ Winter Storm While power has been mostly restored, journalists report Texans are now facing water shortages, housing damage, and crop losses. Texas grocery store shelves have begun filling out again. But for the state’s agriculture industry, recovering from the winter storm will take time, and consumers are likely to feel it in their pockets. The historic freeze and power outages brought agriculture across the state to a halt. Dairy farmers were forced to dump gallons of unpasteurized milk for days as processing plants were left without power. Packing houses also shut down with machinery cut off from electricity and employees unable to make their shifts, said Texas Agriculture Commissioner Sid Miller. Meanwhile, the products on the market were quickly bought up by panicked Texans just before and after the storm. By Monday, Miller said he had seen the price of hamburgers go up to $8.50 a pound, and he expects prices to remain elevated as the food supply chain stabilizes. “It’s not going to be back to normal for at least six to eight weeks,” Miller said. “You’ll still see shortages of some stuff, and even though the shelves may be full, the prices will be high.” Read and listen to the full story in the State of Science series. Keeping An Eye On The Climate, From Space The climate is changing, and so is the U.S. government’s approach to it. The Biden White House has made the climate crisis a high priority, and has created several new positions focused on climate science. One of those new climate posts can be found at the space agency NASA. While rockets and Mars rovers may seem far removed from climate issues, NASA is actually the lead federal agency in climate observations, with a fleet of satellites tracking everything from sea temperature to CO2 levels to chlorophyll. Ira talks with Gavin Schmidt, who has recently been named in an acting role to be the senior climate advisor for NASA. He’s also director of NASA’s Goddard Institute for Space Studies in New York. They discuss upcoming climate-focused NASA programs, last week’s cold weather in Texas, and the challenge of making better decisions in an uncertain climate future.
On an Instagram Live broadcast Monday night, Alexandria Ocasio-Cortez told the world in detail about her harrowing experiences during the Capitol insurrection. 11 House Republicans join all House Democrats in stripping QAnon Representative Marjorie Taylor Green of committee roles. Senate Democrats pass a budget bill in the wee hours this morning paving the way for passing Biden’s $1.9 trillion coronavirus relief package through reconciliation. The bill was passed only after Vice President Kamala Harris cast a tie-breaking vote. Joe Biden fired all 10 members of the Federal Services Impasse Panel this week. The FSIP is a labor panel that settles federal labor disputes between public unions and the different federal agencies, but under Trump, the Panel was stacked with Koch operatives and used to break federal sector unions. Congressional Democrats are pushing Biden to cancel $50,000 in student loan debt. During the campaign Biden says he would support canceling $10,000 in student loan debt, but pressure led by Chuck Schumer, Elizabeth Warren, Ilhan Omar, Ayana Pressley, Alma Adams, and Mondaire Jones seems to be having an effect. White House Press Secretary Jen Psaki tweeted “Our team is reviewing whether there are any steps he can take through executive action and he would welcome the opportunity to sign a bill sent to him by Congress.” The good folks at the American Prospect have an “Executive Action Tracker” on their website as part of their #DayOneAgenda project. Over 1,100 Columbia University students have pledged to go on a tuition strike, saying they refuse to pay full tuition for all on-line classes. This Super Bowl Sunday General Motors will unveil their electrical vehicle line. GM has said they will eliminate all their combustion engine vehicles by 2035. Governor Tom Wolf released his annual budget address on Wednesday. The Governor called for an increase in the personal income tax and a tax credit program that will reduce taxes for 70% of working Pennsylvania families. He also called for the legalization of recreational cannabis use and an increase in the $15 minimum wage. Nikil Saval released a response to Gov. Wolf’s budget proposal, saying that his budget “does much to move funding swiftly, and equitably, to those who need it most.” But, Saval wrote that the absence of vigorous environmental protection to respond to the climate crisis and the budget’s silence on dealing with the housing crisis, especially during the pandemic, represents “two missed opportunities.” Former Montgomery County District Attorney Bruce Castor has gone from political irrelevance to defending Donald Trump during the upcoming impeachment trial. Castor managed to burn every bridge possible while serving as the Montgomery County District Attorney and as the Acting Attorney General of Pennsylvania. Congratulations, Bruce? Kathy Boockvar steps down after a major screw up that set back the fight for a Constitutional Amendment allow abuse survivors access to justice. Scott Perry’s faculty instructor at the Army War College pens an op-ed to the York Daily Record saying that he finds Perry’s behavior “troubling” and calls on Perry to “remove his name from any website that infers, in any way, that the Army War College considers him to be of the same stature” of some of the celebrated graduates of the college. White House Press Secretary Jen Psaki could not say what the future of the Space Force will be under the Biden Administration. She promised to get together with the point of contact with the Space Force for more information. The Space Force flag was waving during the inauguration we should say. On Super Bowl Sunday, SpaceX is launching a commercial for what it’s billing as the “first ‘all-civilian’ spaceflight” as part of their Inspiration4 project with billionaire Jared Isaacman. The commercial tells viewers they’ll have a chance to climb aboard. According to Space.com, there are three non-billionaire seats available: “One seat is up for grabs in a contest to anyone who makes a donation to St. Jude's Children Research Hospital. Another seat will go to a St. Jude's healthcare worker, and the third will go to the winner of an entrepreneur contest run by Isaacman's Shift4Shop.” And in a major shift away from the Trump organization, Biden created a new role at NASA to prioritize Earth sciences to combat the climate crisis. The new Senior Climate Advisor position will report directly to NASA’s administrator. The head of NASA’s Goddard Institute for Space Studies, Gavin Schmidt, will be the acting senior advisor until they fill the role permanently. Sean got shipments of pots this week. That’s pots, plural. Free Will Releases Juice Money - Sour Ale with Plum, Black Currant, Cinnamon, Cardamom, Vanilla, and Milk Sugar.

Cool Science Radio's guest in this episode is Director Gavin Schmidt, of NASA's Goddard Institute for Space Studies . Each year, NASA and NOAA undertake the huge task of measuring the average temperature of the Earth, using an impressive fleet of satellites in orbit, interrogating hundreds of buoys as well as scientists making local measurements all around the globe. Understanding these long-term changes is vital to how we interact with our environment, from planting different crops to managing water resources to predicting the strength of hurricanes.
America faced an inflection point in the climate crisis in 2020. Record-setting fires and environmental devastation were inescapable sights on the news, as the tragic consequences of a warming planet were on display at home and abroad. Meanwhile, the COVID-19 pandemic showed us the reality of living under multiple ecological disasters and the murder of George Floyd and ongoing police and environmental violence further demonstrated the importance of an intersectional approach to environmental justice. And finally, how would American respond? With a historic presidential election and sharp contrasts between President Donald Trump and former Vice President Joe Biden, it was clear much was at stake with the result. This week, host Ty Benefiel takes you through this year in climate change with excerpts from 2020 guests like Dr. Michael Mann, Dr. Robert Bullard, Jamie Margolin, Bill Nye, Julian Brave Noisecat, Tamara Toles O'Laughlin, Rainn Wilson, Rep.

Since 2014, Gavin Schmidt has been director of the influential NASA Goddard Institute for Space Studies, located in New York's Columbia University. One of the institute's key objectives is predicting atmospheric and climate changes in the 21st Century - and Schmidt is one of the world's most trusted guides to the latest data on the impact of rising temperatures and advocate for urgent action to limit climate change and its adverse impacts. Driving Change began our conversation by asking him about how, if at all, the pandemic has shifted his thinking about climate change.
Guest: Dr. Gavin Schmidt, Director of NASA GISSIntroduction:NASA scientists aren’t just focused on OUTER space. They’re also focused on the INNER workings of our atmosphere, oceans, and how each has evolved over time. As past discussions on our show have confirmed, one aspect of our world we know is changing is our climate. Today we’re joined by Dr. Gavin Schmidt, Director of NASA Goddard’s Institute for Space Studies. He’s been at the forefront of climate research, using models to see how our planet has changed over centuries and how it may keep changing for centuries to come. To model a more accurate picture of our planet’s future, we must take a look at the past and understand the impacts that both internal & external forces have had. What kinds of forces, you ask? Well, let’s find out...

The earth's climate is dynamic and complex. Large changes in climate are recorded in ice cores, ocean mud and over the last two centuries, instrumental records. However, to understand the large scale patterns in climate and their changes and drivers, climate models are not only useful, but increasingly necessary to make skillful predictions for the future. Though critically important, understanding the role of climate models is often misunderstood or distorted. Climate scientist Gavin Schmidt discusses how climate models are not only useful, but increasingly necessary. Series: "Bren School of Environmental Science & Management" [Science] [Show ID: 33355]

In Episode 26 of Hidden Forces, host Demetri Kofinas speaks with NASA's Chief Climate Scientist and Head of the Goddard Institute for Space Studies, Gavin Schmidt. The two cut through the controversy surrounding climate change and dive right into the heart of climate science. They parse through the data, explore the climate models, and consider the impact that further warming could have on humanity in the decades to come. What is driving the warming of our planet? What is causing the acidification of the oceans? What is shrinking the ice sheets? What is causing the rise in sea levels, the decrease in snow cover, and the melting glaciers? Is there a causal connection between human activity and the prolonged droughts, intense heat waves, and raging wildfires we have seen in recent years? What are the feedback mechanisms of climate change? How do we measure the impact of losing reflective layers of ice, exposing permafrost, or releasing vapor into the atmosphere? What does the cooling of the upper atmosphere tell us about the cause of global warming? Could changes in solar activity, sunspots and cosmic rays, and their effects on clouds be to blame for climate change? How will humanity respond to more extreme weather events – hurricanes, droughts, floods, and forest fires – as our populations grow and the density of our coastal regions increases? And is there anything we can do, to prepare? Producer & Host: Demetri Kofinas Editor & Engineer: Stylianos Nicolaou Join the conversation on Facebook, Instagram, and Twitter at @hiddenforcespod
