Ocean warming primary cause of Antarctic Peninsula glacier retreat
A new study has found for the first time that ocean warming is the primary cause of retreat of glaciers on the western Antarctic Peninsula. The Peninsula is one of the largest current contributors to sea-level rise and this ...

Climate tipping points: What do they mean for society?
The phrase "tipping point" passed its own tipping point and caught fire after author Malcolm Gladwell's so-named 2000 book. It's now frequently used in discussions about climate change, but what are "climate tipping points"? ...

Expanding Antarctic sea ice linked to natural variability
The recent trend of increasing Antarctic sea ice extent—seemingly at odds with climate model projections—can largely be explained by a natural climate fluctuation, according to a new study led by the National Center for ...

Study helps explain sea ice differences at Earth's poles
Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? A new NASA-led study finds the geology of Antarctica and the Southern ...

Improved modelling of ice-ocean processes
Pine Island Glacier in West Antarctica is currently one of the single biggest contributors to sea-level rise with an estimated volume loss of 1.2mm sea-level equivalent per decade. The loss is caused, at least partly, by ...

A look at melting ice sheets and the threat to sea levels
The predictions only get worse. In 2007, a United Nations panel of scientists studying the rise of sea level related to climate change predicted that, if nothing was done to reduce greenhouse gas emissions, seas could rise ...
