Globally, glaciers and the large ice sheets of Antarctica and Greenland are particularly vulnerable to climate change, risking a significant future contribution to changes in sea levels. At present, there are significant uncertainties, e.g. relating to their stability, which prevent an accurate assessment of their vulnerability. The ‘Arctic amplification’ of global warming is putting pressure on the ecosystems and communities of the region and having an impact at global level as well. The Arctic’s fragile natural ecosystems and societies are under serious threat, and additional human activities, linked to the new economic opportunities that are made possible by climate change, are putting additional pressure on them (Specific challenge, Topic Description).
