The amount of sea level rise that most of us will experience in our lifetimes may be more than double what was previously anticipated, unless we sharply curtail greenhouse gas emissions, according to a new study that factors in emerging, unsettling research on the tenuous stability of the Antarctic Ice Sheet.

Importantly, the study highlights that cuts we could still make to greenhouse gas emissions during the next several years would significantly reduce the possibility of a sea level rise calamity after 2050.

Published Wednesday in the open access journal Earth's Future, the study is the first to pair recently discovered mechanisms that would lead to the sudden collapse of parts of the Antarctic Ice Sheet, such as the disintegration of floating ice shelves and mechanical failure of tall ice cliffs facing the sea. The study also goes a step further by showing how the new projections could play out city by city around the world. Read more...
