Des projets de géo-ingénierie émergent pour tenter de sauver la glace polaire : rideaux sous-marins, pompes à neige, fertilisation des océans… Mais une nouvelle étude montre que ces solutions ne sont que des mirages.

The plans could also unintentionally harm fragile polar ecosystems.
Biosecurity policies may seem onerous and expensive – but they are working to prevent new species from pushing native species out in the Antarctic.
A billion-year-old ‘hydrogen economy’ in the frozen soil of Antarctica provides bacteria with energy, water, and the carbon that makes up their bodies.
Protecting the continent’s remaining pristine wilderness areas is urgent, but achievable.
What will Antarctica look like in 2070? Will the icy wilderness we know today survive, or will it succumb to climate change and human pressure? Our choices over the coming decade will seal its fate.
As well as thousands of deaths and huge destruction, Japan’s 2011 tsunami carried potentially invasive species en masse across an entire ocean.
