“Deployment of geoengineering, including solar radiation management and carbon dioxide removal, would jeopardise not only ecosystems and livelihoods but also human rights, sustainable development goals and international security,” said Barbara Unmüßig, President of the Heinrich Böll Foundation.

Radical proposal to artificially cool Earth’s climate could be safe, new study claims

Experts worry that injecting sulphur dioxide into the atmosphere could put some regions at risk — A new study contradicts fears that using solar geoengineering to fight climate change could dangerously alter rainfall and storm patterns in some parts of the world. Published in the peer-reviewed journal Nature Climate Change, the analysis finds that cooling …

It could worsen the climate, be weaponized and exacerbate geopolitical imbalances, said Silvia Ribeiro, Latin America director at ETC Group, an organisation that looks at socioeconomic and ecological issues around new technologies. “Investments in geoengineering are already providing justifications for high greenhouse gas emitters to continue emitting and postpone real reductions.”

Geoengineering may be used to combat global warming, experts say

IPCC authors suggest there is high agreement that injection of chemicals into stratosphere could help limit rises — The world may increasingly look to geoengineering in the wake of the latest UN climate report, which says it could be adopted as a temporary “remedial measure” if the world heads towards dangerous levels of warming. The …
