Warming Greenland Ice Sheet Passes Point of No Return

Nearly 40 years of satellite data from Greenland shows that glaciers on the island have shrunk so much that even if global warming were to stop today, the ice sheet would continue ...

Sea-Level Rise Could Make Rivers More Likely to Jump Course

River avulsions -- catastrophic floods triggered when a river charts a new path to the sea -- could occur more frequently on rivers as sea levels ...

Warming Threat to Tropical Forests Risks Release of Carbon from Soil

Billions of tons of carbon dioxide risk being lost into the atmosphere due to tropical forest soils being significantly more sensitive to climate change than previously ...

Digital Content on Track to Equal Half 'Earth's Mass' by 2245
