Podcasts about solar geoengineering

In this episode of Hardware to Save a Planet, host Dylan Garrett talks with Luke Iseman, founder of Make Sunsets, about tackling climate change through stratospheric aerosol injection. They explore the challenges of scaling hardware solutions, the urgency of immediate climate action, and the ethical debates around geoengineering. Luke shares his vision for using sulfur dioxide balloons to cool the planet, sparking a thought-provoking discussion on innovation and sustainability.

In an empty parking lot somewhere in northern California, Andrew Song and Luke Iseman inflate a balloon the size of a small car, full of sulfur dioxide. They will then launch the balloon high up into the stratosphere where it will pop, releasing its sulfur dioxide contents. Song and Iseman are the co-founders of Make Sunsets, a geoengineering startup that sells cooling credits. For a price, you can purchase a bit of the sulfur dioxide they're pumping into these balloons and launching into the stratosphere, with the belief it will offset the warming effects of CO2. Because if you send enough sulfur dioxide into the stratosphere --- we're talking a million tonnes a year --- it'll significantly cool our warming planet. But the idea raises scores of complicated scientific and moral dilemmas. In this documentary, John Chipman goes to California to learn about the potential risks and benefits of solar geoengineering. Reported and produced by John Chipman, with assistance from Joan Webber and Catherine Rolfsen. Mixed by Michelle Parise . It originally aired on What on Earth. Storylines is part of the CBC Audio Doc Unit

In the fight against climate change, a controversial new idea is gaining traction: solar geoengineering. Solar geoengineering, or solar radiation modification, is an emerging technology that aims to reflect sunlight back into space to cool planet Earth. In a world that is struggling to bring about the behavioral and political changes needed to reduce climate change, an innovative tech approach might seem like an alluring silver bullet. But the reality is not so simple. In this episode, Sophia sits down with Cynthia Scharf, a senior fellow at the International Center for Future Generations and former senior strategy director for the Carnegie Climate Governance Initiative. They discuss solar geoengineering's risks and promises, as well as its implications for geopolitics and conflict.

Today, we're bringing you a best-of from our archive of over 250 episodes. We're all aware that the consequences of climate change range from rising sea levels, to drought, wildfires, economic disruption and the displacement of populations. We're seeing and living through many of these effects, but is there hope for managing additional risk? A couple years ago we sat down with environmental scientist Chris Field to ask this question. He shared that it's still possible to pave the way to a sustainable future. Take another listen to this episode to hear more about how he thinks we can do this together.Have a question for Russ?

The Risks of Experimenting with the Sun" (from The New York Times). From the report: "This technology could never “restore” the climate but would further destabilize an already disturbed climate system… leading to unforeseen and irreversible ecological disasters, and severely affecting current and future generations". From ForeignAffairs.com: "The Battle Over Blocking the Sun, Why the World Needs Rules for Solar Geoengineering". The report then states: "policymakers have given little attention to the potential dangers of unilateral SAI" (stratospheric aerosol injection, AKA, jet aircraft sprayed aerosol dispersions in our skies). If we remain on the current course, our days are numbered.

Two experts discuss the geopolitical risks of solar geoengineering and the need for global governance frameworks to prevent conflict. --- Solar geoengineering, the deliberate modification of Earth's atmosphere to curb global warming, still seems like science fiction. However, research is progressing rapidly, and geoengineering's potential implementation has drawn the attention of the United States Congress, which has mandated a research plan to explore its human and societal impacts. On the podcast, two experts explore one of the least understood, but potentially weighty societal issues surrounding solar geoengineering, namely the potential for the technology to be the source of geopolitical tension and even war. Scott Moore, Practice Professor of Political Science at the University of Pennsylvania, and Craig Martin, a specialist in public international law at Washburn University, discuss their forthcoming research that considers the uneven distribution of benefits and risks that would result from geoengineering, and how this might lead to conflict between countries. They also explore governance frameworks to help manage geopolitical tensions, if and when solar geoengineering is implemented. Scott Moore is Practice Professor of Political Science, and Director of China Programs and Strategic Initiatives, at the University of Pennsylvania. Craig Martin is a professor of law at Washburn University who specializes in public international law, in particular law pertaining to armed conflict and climate change.

Listen to Future Now #61 I couldn’t believe it when I read about a geoengineering project changing the reflectivity of clouds in our home, the SF Bay Area, in Scientific American, a mainstream science publication! Maybe there is something to all the airplane trails we see these days that will be discussed to major forums. No such luck in looking at the bigger picture of chemtrails, but there is some light on the topic that is now being discussed in the open.  In our fiest hour we also look at Udio, an audio AI program that allows you to create songs on any topic instantly, Tesla Taxi plans, extra stellar sonification, a strange gamma ray burster, and a dead star that has mysteriously come to life!   The second hour is a delightful conversation with Dave Welch, aka ‘Nordic Dave’ at Santa Cruz Voice on his and Amy’s trip to see the total eclipse of the sun last week via his Cessna 182 aircraft. Dave shares with us what it is like to fly private these days, with over 3500 small airports in the US available, many with services, and close to where you want to go.  We ask about the weather, wifi, autopilot, noise, radar, maps, other planes. Dave compares flying private today to taking cross country road trips in the 1960’s and 70’s…very enjoyable!  Later in the show, Dave delves into his passion for incredible audio, building his own amps and speakers for the best sound experiences possible. We greatly enjoyed our time with him, as you will, I’m sure. Enjoy! Nordic Dave and his Cessna 182 and the 2024 Eclipse

Britain's High Court of Justice has ruled whether Julian Assange can appeal an extradition order that would send him to the U.S. Independent journalist Kevin Gozstola, author of Guilty of Journalism, explains the implications of the order and whether the U.S. might file new charges against the Wikileaks publisher, if it finally gets custody of him. They also discuss the significant consequences for press freedom should the case move forward. Then, Eleanor speaks with independent journalist Hilary Beaumont about her recent reporting on solar geoengineering and tribal consent. Hilary outlines how this technology, which involves dispersing sulfur dioxide at high altitudes with the intent of offsetting some of the impact of climate change, represents yet another example of green colonialism. They discuss the negative and positive potential and effects of such methods and the paltry attention corporate media give to issues such as the intersection of Indigenous rights and the climate crisis. GUESTS: Kevin Gosztola is an independent journalist and author. He has covered the Julian Assange legal proceedings in the UK from their beginning, as well as other press-freedom and whistleblower cases, and has been a frequent guest on the Project Censored Show. His book on the Assange case, Guilty of Journalism: The Political Case Against Julian Assange was published in 2023. Gosztola is also the editor of the Dissenter newsletter. Hilary Beaumont is a California-based independent investigative journalist who covers the climate crisis, indigenous rights, and immigration. Her work has been published by The Guardian, Al Jazeera, and High Country News.   The post Press Freedom and the Julian Assange Appeal / Green Colonialism, Tribal Consent, and Solar Geoengineering appeared first on KPFA.

Local opposition to clean energy projects slows the transition to a low carbon energy system. A legal expert explores how a national policy of “repurposed energy” could speed things up. --- Clean energy infrastructure projects often face opposition from communities where they would be built, a fact that stands in the way of efforts to rapidly lower energy-sector carbon emissions.  Alexandra Klass, a professor of law at the University of Michigan Law School, explores how “repurposed energy”, which directs clean energy projects to abandoned fossil fuel sites and marginal agricultural lands, can effectively counter local opposition and accelerate clean energy development.  She also discusses key provisions in the Inflation Reduction Act and Bipartisan Infrastructure Law that support the development of clean energy in legacy energy communities, and offers recommendations for policy to support repurposed energy nationwide. Alexandra Klass is the James G. Degnan professor of law at the University of Michigan Law School, and a visiting scholar at the Kleinman Center for Energy Policy.  Her recent work has focused on repurposed energy and policy recommendations to make it reality.  Related Content A New Era of Policy in Solar Geoengineering  https://kleinmanenergy.upenn.edu/research/publications/a-new-era-of-policy-in-solar-geoengineering/ Ammonia's Role in a Net-Zero Hydrogen Economy https://kleinmanenergy.upenn.edu/research/publications/ammonias-role-in-a-net-zero-hydrogen-economy/ The CO2 Transportation Challenge  https://kleinmanenergy.upenn.edu/podcast/the-co2-transportation-challenge/ Energy Policy Now is produced by The Kleinman Center for Energy Policy at the University of Pennsylvania.

Solar geoengineering. It's not just a question of whether or not to do it, but of how it might be done and why. This week we are joined by Shuchi Talati, founder of The Alliance for Just Deliberation on Solar Geoengineering, to talk about who is making decisions about solar geoengineering and whether or not populations most vulnerable to climate change have a seat at the table. Solar geoengineering or “Solar Radiation Modification/Management (SRM)” is the large-scale and intentional intervention to increase the amount of sunlight reflected back into space. The purpose is to temporarily limit temperature increase. Shuchi walks us through why the Alliance is not for or against SRM, why refusing to discuss or research RSM is potentially an inherently privileged standpoint, and why she believes we should center voices from regions already experiencing horrific climate impacts. Listen in to find out who is currently researching SRM, what the potential risks and benefits are, and how the Alliance plans to make such a controversial topic more open and accessible.

There are several ambitious, "pie-in-the-sky" ideas that have been proposed as potential solutions to climate change. However, these are generally considered speculative and should be approached with caution, as they might have unintended side effects. The scientific community generally agrees that the most effective approach to combating climate change is through reducing greenhouse gas emissions, increasing energy efficiency, and transitioning to renewable energy sources. Here are some speculative, innovative, and ambitious solutions:Geoengineering: This involves large-scale intervention in the Earth's natural systems to counteract climate change. For example, Solar Radiation Management (SRM) techniques, such as injecting aerosols into the stratosphere, aim to reflect a small proportion of the Sun's light back into space.Carbon Capture and Storage (CCS): While already in use to some extent, the idea of deploying CCS at a global scale to remove large amounts of CO2 from the atmosphere is still largely theoretical due to economic and logistic constraints.Space-based Solar Power: Collecting solar power in space, where the sun always shines, and beaming it back to Earth could provide a virtually unlimited supply of clean energy. However, the costs and technological challenges of deploying and maintaining such a system are considerable.Building with Biochar: Biochar is a carbon-rich form of charcoal that, when mixed with soil, can sequester carbon for hundreds or even thousands of years.Direct Air Capture: High-tech machines that act like trees, absorbing carbon dioxide directly from the atmosphere, could be a solution if they can be made economically viable and powered by renewable energy.Nuclear Fusion: If we can make it work, fusion could provide a virtually unlimited supply of power with minimal environmental impact. The challenge is, it's been a few decades away for many decades.These ideas are ambitious and could have significant effects on climate change if they were implemented and effective. However, each of them comes with significant challenges and potential drawbacks, and many are still unproven at the necessary scale. It is likely that a combination of many different approaches will be needed to effectively combat climate change.

Consultation and engagement with civil society in the Global South is essential for inclusive governance of solar radiation modification (SRM), says Dr. Shuchi Talati, the founder of the Alliance for Just Deliberation on Solar Geoengineering in this  C2GTalk. This will not be easy, and requires building trust and knowledge over time, but as international attention to SRM increases, it will be increasingly important to empower vulnerable communities. Talati is an emerging climate technology governance expert co-chair of the Independent Advisory Committee to oversee SCoPEx, an effort to provide oversight for the potential outdoor solar geoengineering experiment proposed by Harvard University. She most recently served as a presidential appointee in the Biden-Harris administration as chief of staff of the Office of Fossil Energy & Carbon Management at the U.S. Department of Energy where she was focused on creating just and sustainable frameworks for carbon dioxide removal.

The topic of climate change ignites impassioned debate worldwide - a topic that has made its way into mainstream dialogue, from wall street to mainstreet, and achieved an extraordinary amount of global investment. The ecosystemic implications of this are fascinating. A global issue - with implications for society, industry, economy and policy. A long-standing debate. Yet clear consensus and paths forward remain elusive, suggesting potential misalignment in systems of information, and incentive. A leading concern is the belief that even the most aggressive reductions of greenhouse gas emissions are unlikely to prevent their harmful impacts - especially to those people, organisms and ecosystems that are already vulnerable. While many believe solar geoengineering shows great potential to manage some components of climate change - it also poses environmental risks and governance challenges of its own. As we consider the global level of discourse, investment in research and development, and regulatory activity - it's imperative we In this episode, our hosts Chris Potter and Marco Annunziata sit down with International Environmental Policy expert Jesse Reynolds to discuss the capabilities and limitations of solar geoengineering, and where we go from here. Show Highlights: “Cutting emissions is a collective action problem where everybody kind of wants to drag their feet and hope that the rest of the world does a good job. And then the benefits of costly emissions cuts go to the future, whereas the costs are born by the present.” –Jesse Reynolds “Climate change economics often quickly gets into the trillions of dollars when you're talking about impacts or very aggressive emissions cuts. In fact, if anything, solar geoengineering looks too cheap, right? We don't need to reduce the cost. That's not a barrier here. So the question in terms of is it effective?It's yes … but. It can be thought of best as a palliative or an analgesic, a type of a medicine that temporary suppresses some of the worst symptoms while a cure is being researched and implemented.” –Jesse Reynolds “It turns out that the opponents of solar geoengineering have managed to stop these field experiments saying it crosses a rubicon, that this will legitimize something that we first need a global dialogue about. And you can see how it's the extremes feeding off of each other with the loser in this process being the generation of knowledge and trust that will be essential if solar geoengineering might be able to reduce climate change risks in the future, especially to the most vulnerable populations in the world.” –Jesse Reynolds Guest: Jesse Reynolds, Environmental Policy Expert Co-hosts: Marco Annunziata, Co-Founder, Annunziata + Desai Partners Christopher Potter, Senior Research Scientist, Ecosystem Science & Technology Branch, NASA Ames Research Center

Does this sound straight out of a science-fiction novel? That's because it is.In "Termination Shock", Neil Stephenson described a near-future earth where climate change has significantly altered human society and follows the attempts of a businessman using solar geoengineering to cool the planet.Luke Iseman, a hardware entrepreneur and solarpunk, read the book and dug into Stephenson's research on solar geoengineering.To his amazement, he found that it was possible and nobody is trying it out!Luke founded make sunsets to experiment with balloons sending sulfur dioxide particles that reflect sunlight into the stratosphere, effectively replicating the process that volcanoes have done for millions of years to cool the planet.In this episode, we're joined by regulatory hacker Eli Dourado to better understand this powerful technology that could help humanity achieve climate mastery.Major innovations often start with hobbyists, tinkerers, and true believers, as Clayton Christenson's "The Innovator's Dilemma" found out. They are not taken seriously by the mainstream for a long time. While starting on a small scale, Luke's experiments have nevertheless engendered controversy in the scientific community.We talk about why science is disconnected from promoting real-world innovation by focusing too much on analysis instead of action and real-world experimentation.The episode is a fascinating journey that helps us better understand the challenges faced by entrepreneurs on the frontiers of science and technology.They are not hailed while they are doing the work, they instead face skepticism often from powerful groups - partly for good reasons as new technology never comes in a mature form, but also partly because incumbents fear for their status.As a result, we learn that entrepreneurs need to build a community of true believers around them on a mission against a hostile mainstream culture.If you are an entrepreneur and seek a community of techno-optimists, join us for upcoming conferences in Prospera, the startup city:Supercharging Health 2023 - A Próspera Builders' Summit, April 21-23 on Roatan.Decentralizing Finance 2023 - A Próspera Builders' Summit, May 5-7 on Roatan.

Tom Neenan and Tiff Stevenson join host Alice Fraser for episode 86 of The Gargle, the weekly topical comedy podcast from The Bugle - with no politics!

This week, Columbia Energy Exchange brings you an episode of another podcast called Catalyst.  It's a weekly show hosted by climate tech veteran Shayle Kann about the future of decarbonization. Each week, different experts, researchers, and executives come on to unpack the latest hurdles to decarbonization and advancing new climate tech solutions.  This episode is all about weighing the risks and rewards of solar geoengineering.  In it, Shayle speaks with a climate modeler named Dan Visioni who conducts research on solar geoengineering at Cornell University's Sibley School of Mechanical and Aerospace Engineering.  They explore key questions, including: What do we know about the potential effects on ozone, precipitation and ecosystems? What do we need to research, and what could we learn by testing? Which could scale faster: carbon dioxide removal or solar geoengineering?   Solar geoengineering could cost a tiny fraction of the amount required to scale up carbon dioxide removal. Does that mean it could buy us time to draw down emissions in a less expensive manner? Or would its relative affordability enable a rogue actor to deploy it without international collaboration? And who gets to make the final decision on whether the world should deploy solar geoengineering? Whose hand is on the thermostat, so to speak? Episodes of Catalyst drop every Thursday. The show is a co-production of Post Script Media and Canary Media.

David Keith has spent his career studying ways to reflect sunlight away from the earth. It could reduce the risks of climate change — but it won't save us.

Shuchi Talati, former chief of staff of the Department of Energy's Office of Fossil Energy & Carbon Management, discusses the need for strong governance to balance the potential benefits of carbon dioxide removal technologies with environmental and social risks. --- This episode is the first in a three-part series that will explore governance challenges surrounding the transition to clean energy.  In early April, the Intergovernmental Panel on Climate Change released its latest assessment report, which warned that the global carbon budget to keep climate warming below 1.5 degrees Celsius is quickly being exhausted, and that the use of technologies to remove carbon dioxide from the atmosphere has become “unavoidable” if climate damages are to be limited. The report has been followed by announcements from leading technology companies of more than $2 billion dollars in commitments to commercialize carbon dioxide removal (CDR) technologies.  The IPCC report, and financing commitments, point to increasing acceptance of emerging climate technologies that were once viewed as options of last resort to address climate change. In the podcast Shuchi Talati, scholar in residence with the Forum for Climate Engineering Assessment at American University, discusses the governance of these emerging climate technologies which, despite their promise, raise concerns around their potential impacts on ecosystems, economies and issues of social equity, and even over the pace of decarbonization itself.  Shuchi Talati is scholar in residence with the Forum for Climate Engineering Assessment at American University, and former chief of staff for the Office of Fossil Energy & Carbon Management at the Department of Energy.

The impacts of climate change continue to grow clearer and more dire, while countries backslide on plans to wean off fossil fuels and cut greenhouse gas emissions to prevent the worst effects of warming. All that has raised the profile of solar geoengineering: the controversial, and still theoretical, method of cooling the planet by injecting tiny aerosol particles into the stratosphere to reflect more of the sun's energy back into space. Climate reporter for Grid News, Dave Levitan joins Thom Hartmann to discuss how solar geoengineering is in drastic need of rebranding.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

One way of fixing this is to make sure that more of that energy is reflected and never even penetrates the lower atmosphere. Solar geoengineering proposes to put particles into the upper atmosphere to increase its reflectivity and thereby reduce the temperature. In the episode I talk with Harvard's David Keith about some of the technical aspects, which role this technique can play in the overall fight against climate change, some of the political challenges as well as current avenues of research.

More than 60 experts, including several past guests on The Sweaty Penguin, made headlines last week for signing a letter that encourages the international community to adopt a non-use agreement for solar geoengineering—a set of technologies that aim to reflect or block out a fraction of the sunlight hitting the Earth in order to artificially cool the climate. But given the urgency of climate change, why do these experts want to take a potential solution off the table? Today, we explore what solar geoengineering could accomplish at its best, what some of solar geoengineering's (arguably insurmountable) challenges would be, and what comes next for this technology.

A climate economist discusses why efforts to cool earth's climate through solar geoengineering appear all but inevitable, and considers the policy questions and political battles to come.---There is no overarching, national debate into the merits of solar geoengineering, which is process to artificially cool the Earth by reflecting sunlight back into space. The technology sounds fanciful, the stuff of science fiction. Yet earlier this year the National Academies of Sciences issued an urgent request to Washington to begin a federal research program into geoengineering. That request has, so far, largely fallen on deaf ears.Climate economist Gernot Wagner believes solar geoengineering is inevitable despite the relative lack of attention the technology has attracted to date. In a recently published book he makes the case for this inevitability, and also presents a compelling argument for why much more research into geoengineering's risks must be completed if is to be put into practice. In the podcast, he explores why solar geoengineering is fundamentally different from other strategies that address climate change, and why research programs into the technology must be tightly governed. He also discusses concern that solar geoengineering's implementation, if inevitable, is likely to stoke fierce policy debate and, quite possibly, geopolitical tensions.Gernot Wagner is a climate economist at New York University and author of the recently published book Geoengineering: the Gamble. He is also co-author of Climate Shock, which was chosen by the Financial Times as a best book in economics in 2015.Related Content Can We Measure Successful Climate Adaptation? https://kleinmanenergy.upenn.edu/news-insights/can-we-measure-successful-climate-adaptation/ Guidelines for Successful, Sustainable, Nature-Based Solutionshttps://kleinmanenergy.upenn.edu/research/publications/guidelines-for-successful-sustainable-nature-based-solutions/ Harvesting the Sun: On-Farm Opportunities and Challenges for Solar Development https://kleinmanenergy.upenn.edu/research/publications/harvesting-the-sun-on-farm-opportunities-and-challenges-for-solar-development/ 

Wir könnten bereits heute die Stratosphäre der Erde künstlich so verändern, dass weniger Sonnenlicht einfällt und die Erde abkühlt. Klingt erstmal nach einer ziemlich dummen Idee. Tatsächlich könnte es das letzte Mittel sein, um die größten Schäden der Klima-Erwärmung doch noch abzuwenden, falls alles andere scheitert. Das sogenannte Solar Geoengineering ist hochriskant, geben sogar dessen Befürworter zu. Ob es trotzdem erforscht werden sollte und welche Rolle technologische Innovation bei der Bewältigung der Klimakrise spielen kann, erfahrt ihr in dieser Folge.

About the “Systems Failure” Series:To kick off the fall 2021 season, we're launching a mini-series of episodes built around a theme we're calling “Systems Failure.” Our conversations will focus on how the economic, technological, and other systems that play a vital role in determining how we live our lives can not only treat individuals and groups of people unequally, but can also exacerbate inequality more generally in society. We'll also talk about strategies to change those systems to make them more equitable.Episode Notes:David Keith has worked near the interface between climate science, energy technology, and public policy for twenty five years. He took first prize in Canada's national physics prize exam, won MIT's prize for excellence in experimental physics, and was one of TIME magazine's Heroes of the Environment. Best known for work on solar geoengineering, David's analytical work has ranged from the climatic impacts of large-scale wind power to an early critique of the prospects for hydrogen fuel. David is Professor of Applied Physics in the School of Engineering and Applied Sciences and Professor of Public Policy in the Harvard Kennedy School. He spends about a third of his time in Calgary, Canada where he helps lead Carbon Engineering, a company developing technology to capture CO2 from ambient air.PolicyCast is a production of Harvard Kennedy School and is hosted by Staff Writer and Producer Ralph RanalliPolicyCast is co-produced by Susan Hughes.For more information please visit our web page or contact us at PolicyCast@hks.harvard.edu.

Wenn die Sonne weniger scheinen würde, könnten wir den Klimawandel aufhalten. Forscherinnen und Forscher denken darüber schon länger nach – Solar Geoengineering heißt das Fachgebiet. Eine der Idee: Einen Vulkanausbruch imitieren, der die Sonne verdunkelt und so den Planeten kühlt. Eine Andere: Spiegel im All aufstellen und mit ihnen die Sonneneinstrahlung reflektieren. Sollen wir solche tiefgreifenden Eingriffe in die Natur wagen? Das diskutieren wir in dieser Woche im »Klimabericht«, unserem Podcast zur Klimakrise. Unsere Gäste sind Ulrike Niemeier vom Max-Planck-Institut für Meteorologie und Johannes Quaas, Professor für theoretische Meteorologie an der Uni Leipzig.

Die Idee klingt verlockend: Wenn die Menschheit mit dem Klimaschutz nicht vorankommt, warum verpassen wir dem Planeten nicht einfach einen Sonnenschutz? Von Vulkanausbrüchen weiß man, dass kleine Partikel in der Atmosphäre die Erde beträchtlich kühlen können. Sollen wir einen solchen Eingriff wirklich wagen?Mit Sophie Stigler und Tomma SchröderHören bis: 19. Januar 2038, 04:14Direkter Link zur Audiodatei

The most recent report from the UN Intergovernmental Panel on Climate change includes discussion of a number of extreme and untested solutions to the climate crisis.  Among these are solar geoengineering – modifying clouds or spraying tiny reflective particles into the upper atmosphere in order to block some of the sun's light and thereby cool […]

In this episode, student Gideon Futerman welcomes researcher Daniele Visioni to discuss the event Solar Geoengineering: Warnings from Scientists, Indigenous Peoples, Youth, and Climate Activists that happened on the 9th june 2021. You can check the recording of the event here: https://youtu.be/Sqlt5lqDpY8 Daniele Visioni is currently a Postdoctoral Researcher at Cornell University, Sibley School of Mechanical and Aerospace Engineering, working with prof. Douglas MacMartin on the newly funded Geoengineering Assessment across Uncertainties, Scenarios, and Strategies GAUSS project. His research is currently focused on studying Sulfate Geoengineering, a form of climate engineering that aims to partially, temporarily, offset the effects of climate change by means of injecting sulfate precursors in the stratosphere in order to reflect a small part of the incoming solar radiation and thus reduce global temperatures.

Tyler Feldgenhaur discusses his exciting paper on the politics of solar geoengineeering research specifically in relation to the U.S policy agenda. A must listen. Felgenhauer, T., Horton, J., & Keith, D. (2021). Solar geoengineering research on the U.S. policy agenda: when might its time come? Environmental Politics, 1-21. doi:10.1080/09644016.2021.1933763 Finally, on your podcast page I didn't see much in terms of participant bios. Are you still looking for that? If so, here is a brief one: Tyler Felgenhauer is Director of Climate Research at the Duke Center on Risk, and a Research Scientist with the Modeling Environmental Risks and Decisions Group (MERDG), at Duke University. His research examines the climate-society system and options for responding to climate change risk in an integrated way, drawing on approaches from systems analysis, modeling, decision analysis, and other analytical methods from public policy, economics, and political science.

There is growing concern that greenhouse gas emissions are not falling quickly enough to avoid dangerous levels of global warming.  As a result, there is the impetus to examine other options.  Among these are geoengineering, which is one of the most contentious issues in climate policy.  Geoengineering embodies many risks that make even seriously considering […]

For decades, the climate conversation has been very predictable. Scientists warn we must cut carbon emissions or the planet will keep warming. But politicians — and voters — are reluctant to make big changes. This is true even though the bad consequences of climate change are already with us — huge wildfires; typhoons becoming stronger. There's still no taste for change. Twenty years from now, that's likely to stay the same. Some people will push for change, but many will deny the need for change or say it isn't a top priority. In the end, humanity will only have last-ditch solutions. One last-ditch solution is solar engineering. Basically, we load airplanes with particles like calcium carbonate to spray into the atmosphere. The particles dim the sun's rays, cooling the Earth. The advantage is that it would be fast. We know this because it has happened before: When Mount Pinatubo erupted in 1991, it spewed about 17 megatons of sun-dimming particles into the sky, cooling the global temperature by about 0.5 Celsius for around 18 months. Now, a group of Harvard scientists wants to start a solar geoengineering program. They plan to launch a test balloon into the sky around June as a first step. “There is a real potential, maybe a significant potential, to reduce the risks of climate change this century — by a lot,” David Keith, one of the lead scientists of the Harvard effort, told the journal Science last December. Of course, there are disadvantages. Dimming the sun could reduce the amount of food farmers can grow and make solar panels less effective. But if we leave things too long, then the only options left for us will be desperate ones. (T) This article was provided by The Japan Times Alpha.
