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.

This article argues that resource and logistical constraints weighing on low-carbon energy and CO2 capture technologies are likely to pave the way for geo-engineering solutions such as Stratospheric Aerosol Injection (SAI), which demand negligible land, material, and energy inputs. This “climate transition without carbon transition”, though technically feasible, is far from being that simple, raising a whole new set of environmental risks as well as geopolitical, institutional, and ethical issues.
