Underground volcanoes spur Antarctic glacier melt

Glaciers in Antarctica are being melted not only by warmer ocean waters but also by underwater volcanoes, a change in our basic understanding of what’s happening underneath West Antarctica’s ice sheet, scientists say. Geothermal heat from underneath is helping melt the region’s Thwaites Glacier, in the headlines recently for its rapid melt and retreat, researchersContinue reading “Underground volcanoes spur Antarctic glacier melt”

New map predicts timing of cities to avoid as sea levels rise

As the world warms, ice melts and water expands, sea level will rise – but faster in some places than others. These simulations, which assume warming in the middle of the range indicated by climate models, provide the best view yet of probable regional variation in sea level rise over the coming decades. Use theContinue reading “New map predicts timing of cities to avoid as sea levels rise”
