News Roundup: the next IPCC report, alternative aerosol particles, and more
In a contentious meeting in late February, the IPCC agreed on outlines that include discussions of SRM for its 7th assessment report. For the first time in IPCC history, the US was notably absent, having been banned from participation by the Trump administration. Meanwhile, Raymond Pierrehumbert and Michael Mann, two prominent climate scientists and critics of SRM argue that the UK government should pull the plug on their Advanced Research and Invention Agency - or Aria - which was created by an act of Parliament and intends to commit £56.8 million or about $73 million to projects that evaluate the feasibility, scalability, and safety of solar geoengineering ideas. In this monthly news roundup, Pete Irvine discusses these and other recent SRM-relevant developments with experts Sandro Vattioni, Post Doctoral Researcher in Atmospheric Physics at ETH Zurich, Alfonso Fernández, Full Professor of Physical Geography at Universidad de Concepción in Chile, Daniele Visioni, Assistant Professor of Earth and Atmospheric Science at Cornell University, and Tyler Felgenhauer, Senior Research Scientist at Duke University and the Duke Center on Risk.Climate Reflections is a production of SRM360, a non-profit knowledge hub supporting an informed, evidence-based discussion of sunlight reflection methods.

SRM Governance with Cynthia Scharf
Cynthia Scharf has spoken with senior policy makers, UN officials, think tanks and NGOs across the world about climate change and sunlight reflection methods (SRM). Eight years ago, when she first began having these discussions, most people did not see SRM as a serious issue with implications for every country in the world. Now, they are interested. But as interest grows, the gap between the research community and policymakers' knowledge has also grown.Join our exclusive conversation with Cynthia Scharf, Senior Fellow at the Center for Future Generations, as she shares what policymakers are thinking about SRM and what information needs to be shared to enable transparency in this controversial space.Climate Reflections is a production of SRM360, a non-profit knowledge hub supporting an informed, evidence-based discussion of sunlight reflection methods.

News Roundup: James Hansen and SRM, Arctic Ice Project Shuts Down, New MCB Studies, and More
What we'll cover:At the end of January, the Arctic Ice Project - formerly Ice 911 - announced they were shutting down. Why? A new study came out this month that draws on focus groups and a survey across 22 countries asking the public who they trust when it comes to information about carbon dioxide removal and SRM. What were the findings?A new literature review identifies research gaps across the field of SRM.Thoughts on a recent paper about SRM transparency problems.A discussion of a recent study focused on how to govern Marine Cloud BrighteningFamous scientist James Hansen's new piece, and what it means for SRMTo discuss the latest SRM news, Climate Reflections Host Pete Irvine is joined by Viktor Jaakkola, Head of Scientific Collaboration at Operaatio Arktis; Michael Diamond, Assistant Professor of Meteorology and Environmental Science at Florida State University; and Rob Bellamy, Senior Lecturer in Climate and Society at the University of Manchester.Climate Reflections is a production of SRM360, a non-profit knowledge hub supporting an informed, evidence-based discussion of sunlight reflection methods.

The Geopolitics of SRM
Climate change will disrupt the geopolitical landscape. So will Sunlight Reflection Methods (SRM). But might SRM help reduce international tensions by reducing the impacts of climate change? Or will these methods cause more or worse disruptions? For this episode of Climate Reflections, host Pete Irvine speaks with geopolitical experts to explore the current geopolitical landscape and how SRM might interact with it to impact international relations.Guests: Olaf Corry, Professor of Global Security Challenges at the University of Leeds, Beth Chalecki, Associate Professor of International Relations in the Political Science Department at the University of Nebraska, Omaha, and Josh Horton, Senior Program Fellow at the John F. Kennedy School of Government at Harvard University.Climate Reflections is a production of SRM360, a non-profit knowledge hub supporting an informed, evidence-based discussion of sunlight reflection methods.

News Roundup: Hottest Year, SRM Under Trump, International SRM Discussions, And More
2024 was the hottest year on record. Could that change how policymakers think about SRM? How might the new administration in the US approach SRM? Do experts think countries will effectively develop international SRM regulations? We discuss a recent paper examining the topic, and find that the outlook is not optimistic. We also discuss another recent study which found that although SAI would cause some deaths, implementing SAI could still save hundreds of thousands of lives for every 1 degree C of cooling, thanks to its reduction in climate change-caused heat-related deaths. Finally, we explore a new book chapter on Cirrus cloud thinning, and answer a question from our listeners.To discuss the latest SRM news, Climate Reflections Host Pete Irvine is joined by Blaž Gasparini, a Senior Scientist at the University of Vienna in Austria, and an expert in Cirrus clouds, Claudia Wieners, an Assistant Professor in Climate Physics at Utrecht University in the Netherlands studying the impacts of Stratospheric Aerosol Injection (SAI) on Atlantic circulation, and Shuchi Talati, a climate technology governance expert and founder and Executive Director of the Alliance for Just Deliberation on Solar Geoengineering.Climate Reflections is a production of SRM360, a non-profit knowledge hub supporting an informed, evidence-based discussion of sunlight reflection methods.

Climate Reflections dives into the world of sunlight reflection methods, also known as solar geoengineering: a set of ideas to reflect a small amount of sunlight back to space to help counteract global warming. This may sound like science fiction, but it’s an idea that scientists really are studying. Join podcast host Peter Irvine, a sunlight reflection scientist, to explore what different ideas are being studied to reflect sunlight, what impact they might have, and what is going on in the world today related to sunlight reflection research.
