Antarctica's Thwaites glacier at risk of collapse and may lead to sea levels rising by two feet

Antarctica's Thwaites glacier has warm water from three directions well under it threatening to destroy the ice sheet and raise global sea levels by up to two feet. A team of scientists from Oregon State University made the most of ice free waters in West Antarctica to look under the glacier - which is about the size of Great Britain. Warm water from the deep ocean is welling up under the glacier from three different directions and mixing under the ice, the researchers discovered. If it collapses it could take other parts of the ice shelf with it and lead to the single largest driver of sea-level rise this century, lead researcher Erin Pettit told Nature. The £39million study involving UK and US scientists was launched after concerns the increasingly unstable glacier may have already started to collapse.
