📊 Their study identifies eight recurring rationales for rejecting the development and potential future use of these technologies and shows how this opposition is increasingly coalescing around the language of “non-use”.

They find that across governments, civil society organisations, and academic networks, opposition to solar geoengineering is growing and is grounded in legal, political, ethical, and scientific concerns.

Who opposes solar geoengineering – and why? - Solar Geoengineering Non-Use Agreement Solar geoengineering is attracting growing attention as a possible response to climate change. Yet as interest in these speculative technologies grows, so too does opposition. Critics are often portra...

Who opposes solar geoengineering – and why?

In a new blog post, Heleen M. Bruggink, Aarti Gupta, Rakhyun E. Kim and Frank Biermann explore this question based on their recent study.

🚨New investigations have revealed the extent to which billionaire philanthropists and governments of wealthy countries are driving research into a range of solar geoengineering technologies.

🚨Geoengineering isn’t the climate “magic bullet” it’s often sold as
❗️Schemes like Stratospheric Aerosol Injection (SAI) include spraying particles to cool the atmosphere but don’t address the root cause of #climatecrisis like greenhouse gas emissions.

There are problems with a geoengineering techno-fix for the climate crisis | Mike Hulme Geoengineering does little to defuse most of the risks that really matter for people – and it runs the risk of making some harms worse

Injecting particulates into the atmosphere isn’t a magical fix for the climate crisis (Mike Hulme) www.theguardian.com/commentisfre...

The conversation features Prof. Stacy D. VanDeveer, Professor of Human Security and Global Governance at the Global Policy School at UMASS Boston, and one of the co-initiators of the initiative calling for an International Non-Use Agreement on Solar Geoengineering

Changes in surface air temperature (°C, left column) and precipitation (mm/day, right column) for 1pctCO2 (red line) and G2 (blue line) simulations relative to the piControl condition for the globe (top row, JJA mean), tropics (middle row, JJA mean), and Indian monsoon region (bottom row, JJAS mean). Lines show the multi-model mean and the shadings show the intermodel standard deviation. The dashed vertical line shows the time of termination of geoengineering in the G2 simulations.

"Upon the termination of the geoengineering, the climatic conditions—temperature, precipitation, winds and moisture would abruptly change to what it would have been under the global warming scenario." (Bhowmick et al. 2021) www.nature.com/articles/s41...

Stardust says it’s important to pursue the possibility of solar geoengineering because the dangers of climate change are accelerating faster than the world’s ability to respond to it, requiring a new “class of solution … that buys us time and protects us from overheating.”

Also: I constantly see this line about "buying time" (KSR says in the pod too).

As if we haven't known about the exact nature of this problem since before I was born??? This is transparently not about 'more time', because they're talking down mitigation

www.technologyreview.com/2025/12/10/1...

So, in this episode of @the-breakdown.bsky.social, Kim Stanley Robinson says 'no one is proposing geoengineering as a replacement for mitigation'. Lots to agree w/ KSR in this ep but this isn't right. A nice example:
