JOB OPPORTUNITIES
UCL Earth Sciences PhD Scholarship | Deadline: 05 February 2024
“If you're from an under-represented group and would like to work on an under-represented field, you could apply to do a PhD on Solar Geoengineering & various other topics.”
Postdoctoral scholar or researcher on climate intervention by seeding polar mixed-phase clouds at University of California | Los Angeles
“The Aerosol-Climate Interactions Group – UCLA are seeking a talented and driven postdoctoral scholar or researcher to join our multidisciplinary team seeking to determine whether seeding wintertime polar mixedphase clouds could be a viable climate intervention technique. This recently proposed technique, termed mixed-phase cloud thinning (MCT), could potentially produce substantial wintertime cooling of the polar regions, thereby mitigating the impacts of global warming on these sensitive regions. Moreover, MCT could have fewer negative side effects than more established climate intervention techniques.”

Blocking the Sun Is NOT a Climate Solution! | Organic Consumer Association
“[W]hen you start to reflect light away from the planet, you can easily imagine a chain of events that would extinguish life on earth.”
That’s what David Keith, one of the world’s top solar engineering scientists, told the New Yorker about his own life’s work.
With a warning like that, it’s easy to see why Mexico is banning solar geoengineering. That, and the fact that a start-up called “Make Sunsets” was caught trying to block the sun in Baja California Sur—without permission from, or even notifying, the government!
Moving in the other direction, the Biden Administration is officially exploring ways to stop sunlight from reaching the Earth, while the European Union has recently floated “a potential international framework” for going forward with research into this misguided and ineffective attempt to address the global climate crisis.
Few policy makers in the U.S. have tried to wrap their heads around this issue, but a group of Rhode Island state legislators have drafted a bill, the Atmosphere Protection Act that’s a great introduction.”
C2GTalk: Why does the world now need to consider solar radiation modification? with Kim Stanley Robinson | Carnegie Climate Governance Initiative (C2G)
“Many objections to solar radiation modification (SRM)--such as the fear it could undermine other forms of climate action--have been overtaken by events, says The Ministry of the Future author Kim Stanley Robinson in this C2GTalk. The world is in a growing crisis, and cutting and removing emissions is taking too long. It’s time to learn whether SRM can help, and how to govern it.
Kim Stanley Robinson is an American science fiction writer. His books include the best-selling Mars trilogy, Red Moon, New York 2140, and The Ministry for the Future. He was part of the U.S. National Science Foundation’s Antarctic Artists and Writers’ Program in 1995 and 2016, and a featured speaker at COP-26 in Glasgow, as a guest of the UK government and the UN.”
David Keith on Climate Systems Engineering | Challenging Climate
“David Keith is a Professor in the Department of Geophysical Sciences at the University of Chicago and the Founding Faculty Director of the Climate Systems Engineering initiative. Keith previously led the development of Harvard’s Solar Geoengineering Research Program.
In this episode, we discuss Keith’s Climate Systems Engineering initiatives, carbon dioxide removal (CDR) and geoengineering techniques. Drawing on David’s decades of expertise, we dive deep into topics such as CDR, solar geoengineering, ice sheet geoengineering.”

Leon Simons: "Aerosol Demasking and Global Heating" | The Great Simplification #105 | Nate Hagens
“On this episode, Nate is joined by climate researcher Leon Simons to unpack recent trends in global heating during 2023 and potential explanations and subsequent projections for the coming year. While the connection between human emitted greenhouse gasses and global warming is scientifically agreed upon, the other complexities and feedbacks of our climate system are still just beginning to be understood. Today, Leon theorizes on the intensity of aerosol masking from particulates such as sulfur, based on the connection between recent changes in marine fuel sulfur requirements and corresponding climate data. How will the global trend towards aerosol reductions affect near and long term global heating? What does this catch-22 mean for potential future climate action and policy? How should we be thinking about creating a more simplified global system in response to the unknown unknowns of our potential future climate?”

Can solar geoengineering help undo climate change? | The State of Knowledge
“One of the more controversial solutions to the effects of the climate crisis is geoengineering, that is according to Harvard’s geoengineering research program, ‘a set of emerging technologies that could manipulate the environment and partially offset some of the impacts of climate change’. But what is the field's current state?”
Geoengineering: Who Should Control Our Atmosphere? | Climate One
“According to the latest IPCC Assessment Report, we’re currently on course for at least 3°C (5.4°F) of warming by 2100 even if all of the voluntary Paris Agreement emissions pledges are fulfilled. Clearly the world needs to do more to reduce emissions. But what if that’s still not enough?”
No 1.5 Without Intervention | Climate Emergency Forum
“The Centre for Climate Repair at the University of Cambridge (CCRC) and the Climate Emergency Forum (CEF) present a panel discussion at COP28 in Dubai, UAE on the topic of "No 1.5 Without Intervention."
This video was recorded on December 10th, 2023 at COP28 in Dubai, UAE, and published on January 11th, 2024.
Charles Gregoire who is co-producer of the Climate Emergency Forum along with Heidi Brault, introduces the event. He emphasizes that limiting global temperature rise to 1.5 degrees Celsius requires interventions beyond emissions reduction.
Professor Hugh Hunt discusses the SPICE project, investigating stratospheric aerosol injection for solar radiation management (SRM) as well as marine cloud brightening. He emphasizes the importance of research in understanding the risks and benefits of these interventions to address the urgent challenges posed by climate change.
Dr. James Hansen, via video recording, highlights the urgency of addressing climate change, emphasizing the need for intervention due to the already surpassed 1.5-degree threshold.
Anni Pokela, a project manager at Operaatio Arktis, emphasizes the severity of the Arctic climate catastrophe and the irreversible damage, even with rapid emissions cuts. She introduces the concept of climate repair, advocating for additional interventions beyond emissions reduction, acknowledging potential risks but stressing the need for research.”
COP28 Debrief to Healthy Planet Action Coalition | Robbie Tulip
“Viktor Jaakkola of Operaatio Arktis and Hugh Hunt of the Cambridge Centre for Climate Repair discussing their experiences and impressions of COP28.
Viktor Jaakkola has been working full-time in Operaatio Arktis for the last year and a half. Operaatio Arktis is a youth-led science communication project based in Helsinki, with a special focus on Arctic sea ice preservation and climate interventions that could help stabilize the climate situation in the Arctic.
Education-wise Viktor has a couple of years of Environmental Economics studies under his belt, but those studies are on break for now.
Professor Hugh Hunt is Deputy Director of the Centre for Climate Repair. He is Professor of Dynamics and Vibrations in the Department of Engineering at the University of Cambridge. He has been a lecturer here since 1989, shortly after obtaining his PhD in Engineering from Cambridge. He is also a College Lecturer and Director of Studies in Engineering at Trinity College. His principal research interest is in albedo enhancement for climate intervention - "how can we refreeze the Arctic?" Within the Centre for Climate Repair he is most interested in the engineering aspects of Marine Cloud Brightening (MCB) and Stratospheric Aerosol Injection (SAI). Other interests include railway noise and vibration, gyroscopes and boomerangs, wave power, renewable energy, tower clocks and the vibration of bell towers.”
