Outdoor field trials which could include injecting aerosols into the atmosphere, or brightening clouds to reflect sunshine, are being considered by scientists as a way to prevent runaway climate change. Aria, the Government’s advanced research and invention funding agency, has set aside £50 million for projects, which will be announced in the coming weeks.

Injecting pollutants into the atmosphere to reflect the sun would be extremely dangerous, but the UK is funding field trials

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.
