As record heatwaves strain European healthcare systems, experts warn that solar geoengineering could carry profound health risks and governance challenges.

Global heatwaves prompt discussions on solar radiation modification technologies. This approach involves significant logistical challenges and potential ecological risks. SRM does not address root cau...

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...

Geoengineering does little to defuse most of the risks that really matter for people – and it runs the risk of making some harms worse

Stratospheric aerosol injection, marine cloud brightening, and cirrus thinning are less effective in cooling the Arctic than the globe and may lead to increased risk of wildfires and permafrost thawin...

Our initiative stands against such emerging initiatives to explore planetary techno-fixes as a climate policy option.

La géo-ingénierie suscite de nombreux fantasmes auprès des complotistes et est une source régulière de fake news

Dans un monde qui se réchauffe et où les réductions d’émissions de GES restent insuffisantes, de nouvelles technologies proposent de refroidir la planète sans toucher pour autant à nos modes de vie. F...

Oceans are on the front line of new planned climate actions, but understanding of novel marine-climate intervention development and deployment remains low. Here a survey among intervention practitione...

Boosté par l’argent de Wall Street et de la Silicon Valley, le projet de refroidir artificiellement le climat sort des marges. Mais l’irruption d’intérêts privés dans ces technologies potentiellement catastrophiques suscite une levée de boucliers chez des scientifiques. 

Advocates of solar geoengineering are dismayed. But why are they surprised?

Editorial: Sun-dimming risks putting the planet’s thermostat under Donald Trump’s control. Better to adopt the precautionary principle with high-stakes science

Advocates of solar geoengineering are dismayed. But why are they surprised?

On September 9th, 2025, we published the article Safeguarding the polar regions from dangerous geoengineering: a critical assessment of proposed concepts and future prospects in the scientific journal...

Chukwumerije Okereke & Nnimmo Bassey warn that experimenting with speculative technologies on the continent is a grave act of climate injustice.

On 7 May 2025, the UK Advanced Research and Invention Agency (ARIA) announced the list of projects to be funded under its £60 million solar geoengineering research initiative. Readers of this blog wil...
