What’s Happening to the Greenland Ice Sheet? (October 2017)

The Greenland ice sheet is one of the largest contributors to global sea level rise, and if completely melted, could add ~7 meters to sea level. In recent years, the imbalance of the ice sheet has increased with warmer atmospheric conditions. In this talk, Visiting Assistant Professor Samiah Moustafa describes the field’s current knowledge on…

Largest Glacier East Antarctic may add to Sea Level Rise (Totten Glacier)

Totten Glacier, the largest glacier in East Antarctica, is being melted from below by warm water that reaches the ice when winds over the ocean are strong — a cause for concern because the glacier holds more than 11 feet of sea level rise and acts as a plug that helps lock in the ice…

The Sciences of the Anthropocene explained

In this opening lecture of the Environmental Change Institute’s MSc in Environmental Change and Management, Professor Yadvinder Malhi discusses the emerging concept of the Anthropocene.
