As the UK and Europe battles with extreme weather warnings, is it time for us to consider some more extreme tactics to tackle the heat? Tom Whipple is joined by Mark Maslin, Professor of Earth System Science at University College London, to explore if solar geoengineering can help.Also on the show, science journalist Lizzie Gibney discusses the "Salah effect", when exposure to celebrities from stigmatised groups can help increase tolerance. She also examines new research into how the atom nucleus contain energy which can be used for telling the time. Plus, how laughter in great apes may have paved the way for the evolution of complex human language.

Climate overshoot, technological acceleration and end-time fascism: Modernity is propelling the entire human race towards the brink of destruction. To deal with the crises at hand, Dipesh Chakratbarty argues, we need to find ways to go beyond the entrenched thought systems, structures of domination and material infrastructures that separate us from each other as well as from the web of life we belong to. Known for his contributions to decolonial thought, the historian later turned towards Earth System Science, arguing for the decentering of human agency and rethinking of politics from beyond the human vantage point. Dipesh Chakratbarty joins Dissens to talk about the project of provincializing humanity, degrowth for the uber rich and the indigineous experience as a source for planetary liberation.

Food security expert David Lobell is immersed in the data of agriculture. He uses satellite imagery, yield data, and advanced computational modeling to analyze the roughly 500 million farms worldwide to increase productivity and ensure global food security – now and in the future. Though food is often taken for granted, feeding a hungry world is our greatest environmental challenge, he says. Lobell goes on to explain how data can do much more than increase yields – it also cuts costs, prevents conflicts, reduces emissions and deforestation, and improves nutrition. Smart farming is key to food security and avoiding the problems that stem from hunger, Lobell tells host Russ Altman on this episode of Stanford Engineering's The Future of Everything podcast.

The consequences of climate change are everywhere. From record-breaking wildfires to catastrophic floods, climate disasters are killing hundreds of thousands and displacing millions. In the past decade alone, climate-related disasters have forced an estimated 250 million people from their homes.So why aren't we moving faster? What's holding back the systemic shifts needed to avoid disaster? Professor Tim Lenton is one of the world's leading climate scientists tackling exactly that question, but with a positive twist. Tim is a Professor of Climate Change and Earth System Science at the University of Exeter and founding Director of the Global Systems Institute. He is renowned for his pioneering work on climate “tipping points”; critical thresholds in the Earth system that, once crossed, can trigger dramatic and irreversible change.More recently, his research has focused on positive tipping points: how rapid, self-propelling shifts in technology, economics and social behaviour could accelerate climate action. His work shows that change does not always move slowly. Under the right conditions, it can cascade.Tim's research and latest book tell a more hopeful story, one in which shifting and adjusting our lifestyles can create a positive ripple of change and steer us away from the current trajectory of climate disaster. In the We Society, join acclaimed journalist and Academy president Will Hutton, as he invites guests from the world of social science to explore the stories behind the news and hear their solutions to society's most pressing problems.Don't want to miss an episode?

Misha Glenny and guests discuss the exchange of cultures and biology across the Atlantic and Pacific after 1492. That was when Columbus reached the Bahamas, a time when Europe had no potatoes, tomatoes, sunflowers or, arguably, syphilis in its most virulent form; the Americas had no cattle, bananas, sugar cane or smallpox. The lists of what was then exchanged are long and as these flora, fauna and diseases moved between continents, their impact ranged from transformation to devastation. In parts of the Americas, European viruses helped kill over 90 percent of the population. In parts of Europe, Africa and Asia populations boomed on the new American foods. Sheep from Europe grazed fertile land into deserts in some parts of the Americas, while the lowered populations in others led to local reforestation which, arguably, is linked to a particularly cold period in the Little Ice Age.WithRebecca Earle Professor of History at the University of WarwickJohn Lindo Associate Professor of Anthropology at Emory University AndMark Maslin Professor of Earth System Science at University College LondonProducer: Simon TillotsonReading listSteven R.

Road salt is a necessary evil during the winter. It is great for melting snow and ice but too much of it isn't great for the surrounding plants and animals. How much is too much and is there a happy balance between driver safety and environmental impact? That is what my guest in this episode has been studying for years and years. This episode my guest is Dr Sujay Kaushal, professor of Geology and Earth System Science at the University of Maryland as we talk about road chemicals and the surrounding environment.

In the final episode of the year, Anna speaks to Professor Tim Lenton (Chair in Climate Change and Earth System Science at the University of Exeter) about climate tipping points – the thresholds where a tiny change could lead to large and often irreversible transformations in the Earth system, with potentially disastrous consequences. Examples of such 'negative' tipping points include the dieback of the Amazon rainforest, the melting of the Greenland icesheet, and the collapse of the Atlantic Meridional Overturning Circulation (AMOC). But not all tipping points are bad. In the interview, Anna and Tim also discuss how the triggering of 'positive tipping points' within human societies could lead to rapid decarbonization.   For further reading, please see: Tim Lenton's book 'Positive Tipping Points: How to Fix the Climate Crisis'. Tim Lenton's article 'Why some tipping points may be positive for the planet' in Chatham House's magazine 'The World Today'.

Mark Maslin is a leading scientist with expertise in climate change and the major challenges facing humanity in the 21st century. He has published over 230 papers in journals, is a Professor of Earth System Science at UCL and the Lead for Climate, Health and Security at the United Nations University. In this podcast, Mark talks about the ways in which we can make a difference to changing the impacts of climate change.

Hear from Prof. Tim Lenton OBE, as we explore the potential of positive tipping points in accelerating the transition to a net-zero economy. What happens when the conversation about climate change shifts from avoiding disaster to unlocking positive change? Suddenly, it's not just about risk - it's about momentum. Because while some systems may be close to dangerous tipping points, others – like clean energy, electric transport, and sustainable food – are tipping in the right direction. That's why in this episode, we explore how to accelerate those positive shifts, including: · How smart policies can trigger widespread, self-reinforcing change across economies and societies; · Why leveraging social norms and human behavior is just as critical as investing in technology; · And what it takes to create the tipping points that move us toward a stable climate, not away from one.

He has more than 25 years research experience, focused on modelling of the biosphere, climate, biogeochemical cycles, and associated tipping points. Tim is renowned for his work identifying climate tipping points, which informed the setting of the 1.5C climate target, associated net zero targets, and nationally determined contributions. Tim works with policymakers and businesses helping them assess the risks of climate change and nature loss and highlighting the opportunities for 'positive tipping points' that can accelerate change towards net zero. In 2023, Professor Lenton led a team of more than 200 people from over 90 organisations in 26 countries to produce an authoritative assessment of the risks and opportunities of both negative and positive tipping points in the Earth system and society. The 'Global Tipping Points Report' produced in partnership with Bezos Earth Fund was published at COP28.

As fall arrives, many regions experience dramatic weather shifts—think early frosts, storms, or unusual temperature swings. Last year, we sat down with Noah Diffenbaugh, an expert on climate change. We discussed the fact that extreme weather is becoming more frequent. Noah pointed out that there are still things we can do to mitigate the impacts of severe weather. We hope you'll take another listen to this episode to learn about the solutions that are within reach. Have a question for Russ?

When it comes to climate change, we often think of tipping points as having a huge negative effect. Be it the loss of ice sheets in the Arctic, the deforestation of the Amazon rain forest or the alteration of ocean currents, scientists have identified several key systems on the Earth that will be impossible to reverse if they cross a critical threshold. But if we look at the situation from the opposite side, there are also several positive tipping points that, given the correct momentum, can potentially halt the crisis the planet is facing. In this episode, we're joined by Prof Tim Lenton, chair in Climate Change and Earth System Science at the University of Exeter, to talk about his latest book Positive Tipping Points – How to Fix the Climate Crisis. He tells us how the pop group A-ha helped Norway to lead the way in the adoption of electric vehicles, how government mandates can act as powerful amplifiers to get us closer to these vital climate tipping points, and how each positive tipping point can feed into another to push us closer to a greener future.

We look at Positive Tipping Points How to Fix the Climate Crisis by Tim Lenton OBE, Chair in Climate Change and Earth System Science, University of Exeter. See more about the book here. Positive Tipping Points How to Fix the Climate Crisis, reviewed We are that point where the interventions and the solutions need to be more drastic, more timely and are much more pressing. Arguably we have already passed many, too many, indicators that suggest humanity has triggered unavoidable changes to our climate and the planet we live on. While climate deniers, suitably funded by vested financial interests aim to negate, cloud and confuse the dialogue by flooding the debate with bad actors and bad science, the data is there, and this is not a time for giving all opinions equal weight. Already even at an anecdotal level, everyone can see that European summers are just getting hotter and hotter, and hotter. When tour guides in Rome die from heat exhaustion, surely the canary in the coalmine is singing loud and clear now, before it expires too. Tim Lenton aims to make the case for why we are in the dire straits that we currently face, with well written and accurate explanations of various tipping points the climate has endured. The first half of the book is occupied with this aspect. Naturally, for us at least, we were most interested in Lenton getting his teeth into what he believes are potential positive tipping points. His logic is plausible, systems can change far quickly than people realise, both negatively but also positively too. A key aspect of this is the difficulty of people to understand the impact of exponential change. Lenton demonstrates that solar power, and renewables in general are surging ahead, aided by the double whammy of falling costs allied with wider adoption. Both of which, combined, bring crossover benefits, and create a virtuous cycle of further growth and price falls. Regardless of fossil fuel lobbyists, the price per unit of renewables continues to tumble, with the positive consequences that subsidies are no longer even needed for it to be a cheaper option than fossil fuel. This is regardless of the trillions of subsidies now paid, counter intuitively to the fossil fuel industry. Soon it will make more sense to simply leave it in the ground. Naturally those countries whose revenue More about the book We can all play a part in triggering positive tipping points that accelerate us out of the climate crisis. How do we get out of a climate crisis of our own making? As global change escalates, we are already starting to experience damaging tipping points in the social, ecological and climate systems that we depend upon - and much worse is to come. These shocks tell us we have left it too late for incremental change to save us: we need to change course fast to avoid the worst, yet we are acting far too slowly. Our supposed leaders appear paralysed by the complexity of the situation or, worse still, determined to maintain the status quo. This is leading to increasing despair, especially among young people. At the same time, hopeful signs of change are also growing fast. The climate movement, the spread of electric vehicles, and the rise of renewable energy are all examples of change accelerating in the right direction. They have all passed tipping points where their uptake becomes self-propelling, taking the status quo by surprise - and they are spreading worldwide. To get ourselves out of trouble in time, we need more of these positive tipping points towards global sustainability, which eliminate greenhouse gas emissions, reverse the destruction of nature, and promote social justice.

His research focuses on understanding how life has transformed the Earth system over the past 4 billion years, and how humans are transforming it now. He uses computer models to simulate the climate and biogeochemical cycles. Tim is renowned for his work in identifying climate tipping points, which informed the setting of the 'well below 2°C' climate target. He is passionate about the opportunities for positive tipping points in human activities to accelerate action towards global sustainability.

As a new warning is released by scientists that trying to offset our carbon emissions by planting trees alone won't work, we investigate the role the Earth's forests are playing in the fight against climate change.Marnie Chesterton is joined by Mark Maslin, Professor of Earth System Science at University College London, to help answer our top five questions about trees and CO2. We also speak to science writer and New York Times columnist Carl Zimmer about his new book ‘Air-Borne: The Hidden History of the Life We Breathe', and what it tells us about what we're breathing into our lungs each day. After we reported on the plight of some of our UK wild bird species earlier this year, many listeners got in touch wanting to know more about one species in particular: house sparrows. To look at why their numbers have been declining so sharply, and what we might be able to do about it, we hear from Imperial College London's Dr Julia Schroeder, who has been studying the birds for 15 years.And Marnie is joined in the studio by Lizzie Gibney, Senior Reporter at Nature, to explore some of the fascinating research from around the world in this week's science journals.Presenter: Marnie Chesterton Producers: Clare Salisbury, Dan Welsh and Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

Buy Hexen 2.0 Tarot and the forthcoming Hexen 5.0 Tarot: https://cosmogenesis.worldPreview Hexen 5.0's: new images: https://www.suzannetreister.net/HEXEN_5/HEXEN5.htmlLars Bang Larson's Essay: https://www.suzannetreister.net/HEXEN2/HEXEN_2_LBLessay.htmlNote: if you were watching the tarot deck flip through on YouTube, you are seeing the Hexen 2.0 deck.About the new deck:HEXEN 5.0, an update of HEXEN 2.0 (2011), presents a critical, historical and mystical exploration of new global developments in terrestrial and interplanetary technologies, science and communications, corporate and governmental forces, the ecosystem and climate crisis, recent and traditional fields of knowledge and spirituality, new branches of bio/socio/political theory, contemporary countercultural and futuristic movements, new directions in science-fiction, and proposed possible solutions for an ethical survival of the human race.The visual structure of the works is largely based on alchemical drawings of the 13th - 18th centuries, entwining these subjects into a holistic mystical space where they become differently animated and resonant. In alchemical drawings, science, art and religion/spirituality co-exist, echoing the recently converging fields illuminated in some of the cards, such as Spiritual Ecology, Nexus thinking and Earth System Science, fields which may lead to better solutions for the climate crisis and to returning the planet towards a self-regulating system.Where HEXEN 2.0 analysed the legacy of cybernetics as embodied in Web 2.0 and systems of control, showing how Web 2.0 works as a societal controlling system, HEXEN 5.0 traces cybernetics' relevance to whole earth systems and how the cybernetic self-regulating feedback loops of the planetary ecosystem, which we have sent out of whack, need to be addressed through an understanding of the workings of the total global ecosystem. This is embodied in the aims of Earth System Science and potentially in an even more holistic system incorporating traditional knowledges and spirituality.The published deck of tarot cards is intended to be used as a tool for groups to discuss and envision positive alternative futures and may be used in conjunction with HEXEN 2.0 Tarot deck.Support the showSupport the podcast:https://www.acidhorizonpodcast.com/Linktree: https://linktr.ee/acidhorizonAcid Horizon on Patreon: https://www.patreon.com/acidhorizonpodcastJoin The Schizoanalysis Project: https://discord.gg/4WtaXG3QxnSubscribe to us on your favorite podcast: https://pod.link/1512615438Merch: http://www.crit-drip.comSubscribe to us on your favorite podcast: https://pod.link/1512615438 LEPHT HAND: https://www.patreon.com/LEPHTHANDHappy Hour at Hippel's (Adam's blog): https://happyhourathippels.wordpress.com​Revolting Bodies (Will's Blog): https://revoltingbodies.com​Split Infinities (Craig's Substack): https://splitinfinities.substack.com/​Music: https://sereptie.bandcamp.com/ and https://thecominginsurrection.bandcamp.com/

His scientific work examines the study of species interactions in tropical ecosystems from California, Latin America, and other tropical areas of the world. Recent research highlights the decline of animal life (“defaunation”), and how this affects ecosystem processes/services (e.g. disease regulation).   In this episode, we first talk about species interactions, and the role they play in evolution. We also talk about hybrid networks, and how they can be disrupted by human activity. We discuss why biodiversity conservation is so important, and how climate change impacts animal populations. We then talk about mass extinctions, and we focus on the ongoing sixth mass extinction. Finally, we discuss the signs that the sixth mass extinction is the result of human activity, and how it can impact humans. -- A HUGE THANK YOU TO MY PATRONS/SUPPORTERS: PER HELGE LARSEN, JERRY MULLER, HANS FREDRIK SUNDE, BERNARDO SEIXAS, OLAF ALEX, ADAM KESSEL, MATTHEW WHITINGBIRD, ARNAUD WOLFF, TIM HOLLOSY, HENRIK AHLENIUS, JOHN CONNORS, FILIP FORS CONNOLLY, DAN DEMETRIOU, ROBERT WINDHAGER, RUI INACIO, ZOOP, MARCO NEVES, COLIN HOLBROOK, PHIL KAVANAGH, SAMUEL ANDREEFF, FRANCIS FORDE, TIAGO NUNES, FERGAL CUSSEN, HAL HERZOG, NUNO MACHADO, JONATHAN LEIBRANT, JOÃO LINHARES, STANTON T, SAMUEL CORREA, ERIK HAINES, MARK SMITH, JOÃO EIRA, TOM HUMMEL, SARDUS FRANCE, DAVID SLOAN WILSON, YACILA DEZA-ARAUJO, ROMAIN ROCH, DIEGO LONDOÑO CORREA, YANICK PUNTER, ADANER USMANI, CHARLOTTE BLEASE, NICOLE BARBARO, ADAM HUNT, PAWEL OSTASZEWSKI, NELLEKE BAK, GUY MADISON, GARY G HELLMANN, SAIMA AFZAL, ADRIAN JAEGGI, PAULO TOLENTINO, JOÃO BARBOSA, JULIAN PRICE, EDWARD HALL, HEDIN BRØNNER, DOUGLAS FRY, FRANCA BORTOLOTTI, GABRIEL PONS CORTÈS, URSULA LITZCKE, SCOTT, ZACHARY FISH, TIM DUFFY, SUNNY SMITH, JON WISMAN, DANIEL FRIEDMAN, WILLIAM BUCKNER, PAUL-GEORGE ARNAUD, LUKE GLOWACKI, GEORGIOS THEOPHANOUS, CHRIS WILLIAMSON, PETER WOLOSZYN, DAVID WILLIAMS, DIOGO COSTA, ANTON ERIKSSON, CHARLES MOREY, ALEX CHAU, AMAURI MARTÍNEZ, CORALIE CHEVALLIER, BANGALORE ATHEISTS, LARRY D.

The Los Angeles area continues to be devastated by horrific January wildfires, which have killed at least five people and destroyed an unknown number of homes. The fires have been fueled by a dry rainy season in the Southland and fierce Santa Ana winds, topping out at 100 miles an hour. There's been only about a third of an inch of rain in downtown LA since the rain season began in October, and none at all since the start of winter, far below the normal amount of precipitation the southland usually receives. That combined with this historic wind event made conditions ripe for just the kind of devastation we are seeing. For more, KCBS Radio News anchors Patti Reising and Bret Burkhart and KCBS political reporter Doug Sovern spoke with Stanford climate scientist Noah Diffenbaugh, professor in the Department of Earth System Science and Senior Fellow at the Woods Institute for the Environment at Stanford University.

Climate change authority Noah Diffenbaugh says that the effects of climate change are no longer theoretical but apparent in everyday, tangible ways. Still, he says, it is not too late to better understand the effects of climate change, to mitigate them through reductions in greenhouse gas emissions and other measures, and to adapt how we live in the face of a warmer planet. Society is falling behind in its ability to deal with increasingly extreme climate events but solutions are not out of reach, Diffenbaugh tells host Russ Altman on this episode of Stanford Engineering's The Future of Everything podcast.Have a question for Russ?

Climate 'tipping points' are the dangerous phenomena that could suddenly make climate change even worse than it is already: melting ice sheets that could change ocean currents, thawing permafrost that releases vast amounts of methane, or rainforests turning into dry savannah - events that could completely destabilise the global environment and would be hard or impossible to reverse. But, according to a growing number of climate scientists, there is also the prospect of ‘positive tipping points'. Things that can happen to speed up the reduction in greenhouse gas emissions in ways that humanity has so far failed to achieve. One of those is Tim Lenton, Professor of Climate Change and Earth System Science at the University of Exeter. As you will hear in the interview, other climate experts use terms such as 'social tipping points' or 'sensitive intervention points' - Professor Lenton says these are similar concepts that altogether should dispel the notion that we are doomed by climate change.

This week, the team talk positive tipping points, grapple with the comms coming out of the pre-COP meets and send our tributes to dearly loved colleagues who have recently passed.  With pre COP 28 meetings currently taking place, the host team discuss the mixed messaging that is currently making headlines and anticipate what this might mean for how the future of fossil fuels will appear in the final text at COP 28.  Tim Lenton, the founding Director of the Global Systems Institute at the University of Exeter and Chair in Climate Change and Earth System Science is our guest this week, and with Tom unable to make the interview, our brilliant colleague from Global Optimism, Freya Newman, joins Christiana and Paul to interview her former professor. With negative tipping points racing along their own ‘S curve', the team ask Tim Lenton whether there are signs that the positive tipping points can win this race and avert the worst impacts of the climate crisis (pssst, the answer is it looks very, very possible).  Music this week comes from Jemima Coulter with their beautiful song ‘[flowers]'.

In this episode, Associate Professor of Climate Change and Sustainability Dr. Francesca Hopkins talks with students from the UC Riverside School of Public Policy about comprehensive solutions to climate change, as well as the importance of local change amid global warming.   About Francesca Hopkins: Francesca Hopkins earned her B.A. in Environmental Studies and Spanish from the University of California, Berkeley. She also completed her M.S. and Ph.D. in Earth System Science from the University of California, Irvine. Before joining the University of California, Riverside Department of Environmental Studies as an Assistant Professor of Climate Change and Sustainability, Francesca was a NASA Postdoctoral Fellow at NASA's Jet Propulsion Laboratory. Currently, Francesca runs the UCR Greenhouse Gas Emissions Lab, which studies emissions that affect the climate and air quality with the goal of developing the science to reduce these emissions.  Learn more about Francesca Hopkins via https://www.linkedin.com/in/francesca-hopkins-a904822/  Podcast Highlights:   “There's so many other ways we contribute to climate change... So I think we always need to think about what are these solutions that are going to give us a 'win-win'. Not just reduce emissions, but increase our joy and help us feel good. I think those are the best ones.” -       Francesca Hopkins on the topic of how solutions to climate change can better other aspects of our lives, such as mental health and well-being.  “Cities have a really unique power and role in reducing transportation emissions, because they're often in control of what gets built, how it gets built. And really, we need to think about changing the form of our cities in California, so they're not so spread out [to promote reduced emissions by walking more]. And that's going to solve other problems, hopefully, including housing affordability issues that we have, and building houses in wildfire prone areas.” -       Francesca Hopkins on the topic of the power of city planning to reduce emissions.  “Because right now, we have a chance to redesign our future. We can actually create the world we want. And we definitely need to think about how the climate is impacting that. But we can do that without knowing how tropical storm tracks might change slightly in the next decades, I would argue.” -       Francesca Hopkins on the topic of how slight uncertainties as to the exact effects of climate change don't need to be resolved to take effective action.   Guest: Francesca Hopkins (Associate Professor of Climate Change and Sustainability)  Interviewer: Rachel Strausman (UCR Public Policy Major, Dean's Vice Chief Ambassador)  Episode image designed by Freepik (www.freepik.co) Commercial Links:https://spp.ucr.edu/ba-mpphttps://spp.ucr.edu/mpp  This is a production of the UCR School of Public Policy: https://spp.ucr.edu/  Subscribe to this podcast so you don't miss an episode.

In this episode of the Speaking Out of Place podcast, Professor David Palumbo-Liu speaks with June Choi, Yannai Kashtan, and Belinda Ramírez from the Coalition for a True School of Sustainability. Amidst great fanfare, Stanford University created the Doerr School for Sustainability, which immediately said that it would accept funding from the fossil fuel industry. June, Yannai, and Belinda are helping lead the movement of students pushing back to dissociate from such funds. David asks what drives them and sustains them in building a True School of Sustainability.www.truesustainabilityschool.comwww.ejstanford.comJune Choi is a PhD candidate in Earth System Science at the Doerr School of Sustainability. Her research focuses on quantifying the impacts of climate change to inform adaptation strategies. Her previous work involved tracking global climate finance flows, setting standards for green bonds and sustainable finance integrity. She holds an MA in International Relations from John Hopkins University and BA in Sociology from Amherst College.Yannai Kashtan is a PhD candidate in Earth System Science at the Doerr School of Sustainability, where he studies health-related hazards of residential fossil-fueled appliances. His most recent project quantified benzene emissions from gas and propane stoves. He earned a BA from Pomona College, where he majored in physics and chemistry and studied organic semiconductors.Belinda Ramírez (they/them) teaches introductory liberal education courses at Stanford as a COLLEGE Fellow, including courses on environmental sustainability, food and culture, and climate/environmental/food justice. They also organize with Stanford's Environmental Justice Working Group and the Coalition for a True School of Sustainability. Trained in cultural anthropology, their research deals with the social, racial/ethnic, political, and economic dimensions of urban agriculture and other food movements situated within the modern industrialized and corporatized global food system. In researching these topics, Belinda has come to recognize the fulfillment found in experiential learning and working firsthand to change their local food system, receiving agricultural training through local farms and community gardens in southern San Diego. They have also engaged in statewide political advocacy for young farmers through the National Young Farmers Coalition, served as both Board and Food Justice Co-Chair for Slow Food Urban San Diego, and worked as a Soil Farmer for Food2Soil. They consider themselves a farmer-scholar, bridging the worlds between praxis and theory, academia and tangible, on-the-ground work.www.palumbo-liu.com https://speakingoutofplace.comhttps://twitter.com/palumboliu?s=20

In this episode of the Speaking Out of Place podcast, Professor David Palumbo-Liu speaks with June Choi, Yannai Kashtan, and Belinda Ramírez from the Coalition for a True School of Sustainability. Amidst great fanfare, Stanford University created the Doerr School for Sustainability, which immediately said that it would accept funding from the fossil fuel industry. June, Yannai, and Belinda are helping lead the movement of students pushing back to dissociate from such funds. David asks what drives them and sustains them in building a True School of Sustainability.www.truesustainabilityschool.comwww.ejstanford.comJune Choi is a PhD candidate in Earth System Science at the Doerr School of Sustainability.

If a negative climate tipping point refers to a critical threshold that triggers irreversible damage, then it stands to reason that a positive tipping point is the exact opposite - a beneficial axis that, when reached, staves off the worst planetary outcomes. Our guest today, Dr. Tim Lenton, is the Chair in Climate Change and Earth System Science at the University of Exeter and is the Founder of the Global Systems Institute, an organization that uses a whole systems approach to solve global challenges and build a flourishing future. In this interview, we look at some examples of positive tipping points, discuss the social movements that are having real impact, and the individual actions we can all take to lower our carbon footprint. Show NotesProfessor Tim Lenton, University of ExeterGlobal Systems InstituteEarth System Science: A Very Short Introduction by Tim LentonRevolutions That Made the Earth by Tim Lenton and Andrew WatsonGaia: A New Look at Life on Earth by Jim Lovelock Positive Tipping Points Could Save the Climate - This Man is Showing Us How (Positive.News)

Getting Curious is going spelunking! Caves are full of evidence about our Earth's past: they can tell us about monsoons in Laos and sea surface temperatures in Mexico over tens of thousands of years ago. They can also help predict our climate future. This week, Professor Kathleen R. Johnson takes us through the incredible world of caves and shares what it's like to scale 200-foot ladders, kayak all day in the dark, and encounter pythons, big ass spiders, and other creatures along the way—all in the name of science! Kathleen Johnson is a Professor in the Department of Earth System Science at the University of California, Irvine (UCI). She is a geochemist and a paleoclimatologist who specializes in reconstructing past climate changes using stalagmites from tropical and monsoon regions, with current projects in Laos, Vietnam, and Mexico. In addition, she directs the new UCI CLIMATE Justice initiative which aims to culturally transform the geosciences through training postbaccalaureate and PhD Fellows in community-engaged research practices and environmental justice.

Can we imagine a world where we leave half the earth to the natural environment and use the other half for ourselves? Can we change history and protect the Indigenous, the vulnerable, and the very poorest in society?Mark Maslin is a Professor of Earth System Science at University College London. Maslin is a leading expert in understanding the anthropocene and how it relates to the major challenges facing humanity in the 21st century. He has written a number of books on the issue of climate change, his most book is How to Save Our Planet: The Facts."I think the most important thing is realizing how much impact humans have had on the planet. For example, did you know that we move more rock and sediment than all the natural processes put together? We also have created enough concrete already to cover the whole world in a layer that's two millimeters thick, and that includes the oceans. We have also created and make something like 300 million tons of plastic every single year, which we know ends up in our rivers. It ends up in our oceans. And we've also found that microplastics have been found in human blood. So this is the impact we're having all around the world. We've also cut down 3 trillion trees, that's half the trees on the planet. We have doubled carbon dioxide in the atmosphere. We've increased methane by about 150%, which has led to a warming of the planet of about 1.2 degrees Celsius. And If you weigh the land mammals, 30% of that weight is us humans. There are 8 billion of us, and I have to say a few of us could lose a few pounds, but 67% of that weight is our livestock. And just 3% is those wild animals. So in less than 5,000 years, we've gone from 99% being wild animals to less than 3%. That's how much impact we humans have had on the planet."www.geog.ucl.ac.uk/people/academic-staff/mark-maslinwww.penguin.co.uk/books/320155/how-to-save-our-planet-by-maslin-mark/9780241472521www.creativeprocess.info www.oneplanetpodcast.org IG www.instagram.com/creativeprocesspodcastAll images courtesy of Mark Maslin

A star in the nearby Pinwheel Galaxy has exploded spectacularly into a supernova, dubbed SN 2023ixf. It is the brightest in a decade and it has got astronomers around the world into a frenzy. Science in Action hears from both amateur and professional astronomers alike as they scramble to collect exciting new images and data. Back on the ground, we hear from the Professor of Climate Change and Earth System Science at the University of Exeter, Tim Lenton about his new paper highlighting how rising global temperatures could push human populations from their homes.

COVID-19's Lingering Toll On The Heart As new omicron-specific boosters against COVID-19 unroll in cities around the US, research is revealing more about the longterm consequences of even one infection with the SARS-CoV2 virus. Writing this week in Nature Medicine, a team of researchers from Germany describe finding long-lasting signs of heart disorders in the majority of recovered patients in their study group–even up to nearly a year later. FiveThirtyEight's Maggie Koerth joins Ira to describe the research and how it fits into what we're learning about the scope of Long Covid. Plus taking the temperature of the melting Thwaites Glacier, new insights into the genes of both immortal jellyfish and human astronauts, and a post-mortem of the world's first known amputation. Why Are Dead Fish Piling Up Across The San Francisco Bay? Thousands of dead fish are piling up across the Bay Area. From the concrete outer edges of Oakland's Lake Merritt to the sandy beaches of San Francisco's Fort Funston and the pebbled banks of Oyster Point in San Mateo County, the carcasses of fish likely poisoned by a harmful algal bloom — more commonly known as a red tide — are washing ashore. It's a mass-death event the San Francisco Bay hasn't seen the likes of in years, says Jon Rosenfield, senior scientist with environmental group San Francisco Baykeeper. “From a fish's point of view, this is a wildfire in the water,” he said. By SF Baykeeper's count, the number of fish dying off in the San Francisco Bay could easily exceed hundreds of thousands, and that, Rosenfield said, might even be a “low” estimate. His field investigator confirmed “easily tens of thousands of fish dead” in Lake Merritt alone. But Rosenfield cautioned, “What you see is just the hint of what's actually happening further beneath the water's surface and in places you're not getting to on the shoreline. So it's really an uncountable number.” It may be harmful to humans, too. An algal bloom of this size can cause skin irritation and respiratory problems, and the San Francisco Bay Regional Water Quality Control Board is advising people to avoid swimming, kayaking or other activities on the water until the bloom subsides. Read the full story at sciencefriday.com. As Temperatures Get Warmer, Fish Are At Risk Climate change is expected to have a big effect on a sensitive group of creatures: fish. A new study out of the University of Arkansas predicts that there is likely to be a six-fold increase in large fish mortality events between now and 2100, specifically in freshwater lakes in Minnesota and Wisconsin. Known as “summerkills” and “winterkills”, seasonal die-offs are a part of fishy nature, but have been happening at a greater frequency as temperatures increase. That's due to climate change-related factors like algal blooms, infectious disease, and oxygen deprivation. Joining Ira to talk about the future for freshwater fish is Simon Tye, PhD candidate in biology at the University of Arkansas in Fayetteville.  As The World Decarbonizes, Sulfuric Acid May Be In Short Supply A move towards more alternative energy sources and away from fossil fuel production is a net positive for the world. But there's an unanticipated side effect—a possible global sulfuric acid supply shortage. Eighty percent of the world's sulfuric acid is the byproduct of fossil fuel production. Cutting back on coal, oil, and natural gas means producing less sulfur acid. That's important as sulfuric acid is critical to making fertilizer, as well as green technology like solar panels and batteries. Ira talks with Mark Maslin, professor of Earth System Science at University College London, about his latest research, which points to a looming sulfur shortage. The New G.O.A.T Of Park Systems Is An Actual Goat If you walk into a park, the odds are pretty high that you'll find an invasive plant species, like buckthorn, giant hogweed, or multiflora rose. These resilient plants can often grow uncontrollably and out-compete native species for resources, which has consequences for native wildlife that depend on other native plants. They can also be incredibly difficult to remove. That's why a growing number of parks across the United States are turning to unlikely helpers: goats. Conservation grazing is a practice in which livestock are used to maintain biodiversity. Because goats eat almost everything, they chow down on invasive plants and make them much easier to remove. Radio producer Rasha Aridi speaks with Hillary Steffes, the chief goat herder at Allegheny GoatScape in Pittsburgh, Pennsylvania, about using goats as a conservation tool. Then, Rasha takes a trip to Riverside Park in NYC to meet some goats, and talk with Marcus Caceres, a field supervisor at the Riverside Park Conservancy. Transcripts for each segment will be available the week after the show airs on sciencefriday.com.        

Melvyn Bragg and guests discuss one of our ancestors, Homo erectus, who thrived on Earth for around two million years whereas we, Homo sapiens, emerged only in the last three hundred thousand years. Homo erectus, or Upright Man, spread from Africa to Asia and it was on the Island of Java that fossilised remains were found in 1891 in an expedition led by Dutch scientist Eugène Dubois. Homo erectus people adapted to different habitats, ate varied food, lived in groups, had stamina to outrun their prey; and discoveries have prompted many theories on the relationship between their diet and the size of their brains, on their ability as seafarers, on their creativity and on their ability to speak and otherwise communicate.
