Greenland’s glaciers have retreated so far that they can no longer support the ice sheet that feeds them. The ice sheet system has reached a new normal of consistent annual ice loss.

For the first time, scientists have been able to quantify how much climate change contributed to glacial melt, using more than 40 years of data from New Zealand’s retreating glaciers.

Auckland’s extreme drought and the rapid retreat of glaciers in the Southern Alps both highlight how important long-term observations are for water management policy and planning.
Since the last ice age, the ice sheet retreated over a thousand kilometres in the Ross Sea region, more than any other region on the continent.

New research shows that ocean and air temperatures both contributed to the melting of Antarctica’s Ross Ice Shelf in the past, but melting from below by a warming ocean became more important over time.
