Une carte interactive du monde , développée par ETC Group et la Fondation Heinrich Böll, a mis en lumière l'ampleur des expériences de géo-ingénierie visant à modifier le climat. La carte identifie plus de 1 700 projets dans le monde, notamment la capture du carbone, la gestion du rayonnement solaire, la modification du temps et d'autres méthodes.

Firms are flocking to invest in geoengineering projects. Could such startups turn a profit by preventing climate peril? Luke Iseman is emboldened by all the criticism, personal attacks and negative press he has received. This article is guilty of feeding into that feedback loop — of lending some legitimacy to what he’s done. Many of the world’s atmospheric scientists will say this is dangerous, and they’re probably right.

Techniques such as solar radiation management may have unintended consequences, scientists say

During the past decades, the idea of acting to counteract the damage done to the ecosystem by humankind's activities has moved along at least two planning stages.

Pie-in-the-sky fantasies of carbon capture and geoengineering are a way for decision-makers to delay taking real action

Mexico announced this Tuesday a set of measures to ban solar geoengineering experiments in the country, after a US startup began releasing sulfur particles into the atmosphere in the northern state of Baja California.

The federal effort could set the stage for more studies into the feasibility, benefits and risks of one of the more controversial means of combating climate change.

More climate scientists say emissions cuts are not enough and we face imminent catastrophe unless deliberately altering the climate. What are the options and challenges? Jem Bendell interviewed Dr Ye Tao who is proposing we use massive amounts of mirrors to reduce harm in the short term.

Around the world, dozens of ingenious projects are trying to ‘trick’ the ocean into absorbing more CO2. But critics warn of unforeseen consequences

The United States and Saudi Arabia have hamstrung global efforts to scrutinise climate geoengineering in order to benefit their fossil fuel industries, according to multiple sources at the United Nations environment assembly, taking place this week in Nairobi.
