Alaska’s top-heavy glaciers approach irreversible tipping point

Enlarge / The Taku Glacier is one of many glaciers that originate in the Juneau Icefield. The melting of one of North America’s largest ice fields has accelerated and could soon reach an irreversible tipping point. That’s the conclusion of new research colleagues and I who have published on the Juneau Icefield, which straddles the … Read more

The Antarctic ice sheet is melting in a new, worrying way that scientific models used to project future sea level rise have not taken into account. This suggests that current projections could significantly underestimate the problem, according to a new study. Scientists from the British Antarctic Survey found that warm ocean water seeps under the … Read more
