Melting ice sheets are often considered synonymous with climate change in the media, with evocative images of lone polar bears floating on ever-shrinking rafts of ice. While impacts such as sea level rise and salinity changes ...
A slow climate feedback loop may be bubbling beneath Antarctica's vast ice sheet. The continent, divided east to west by the Transantarctic Mountains, includes volcanic giants such as Mount Erebus and its iconic lava lake. ...
