Thwaites: countdown to disintegration

Camille Lin

The Thwaites Glacier is living out its last years of stability: the disintegration of its floating shelf has begun. As spectators of a predicted collapse, we witness the countdown of a colossus whose melting could raise the oceans by 65 centimetres.

Ancient poppy seeds and willow wood offer clues to the Greenland ice sheet’s last meltdown and a glimpse into a warmer future

Close inspections of the soil beneath the Greenland Ice Sheet show that less than one million years ago it was almost entirely gone.

As Greenland melts and rises

Mirjana Binggeli

With the rapid melting of the ice masses covering Greenland, the island has risen by 20 cm in 10 years. A situation that will pose certain problems for Greenland.

A preserved landscape discovered beneath the Antarctic ice cap

Mirjana Binggeli

A preserved landscape has recently been discovered beneath the East Antarctic ice sheet. A discovery that could help us understand how the ice sheet was formed and how it could evolve under conditions of global warming.

Greenland - A winter flood under the ice cap

Camille Lin

An event in the life of glaciers that had never been observed before has just surprised glaciologists.

Heat in Canada as a benefit for Greenland's ice sheet

Dr. Michael Wenger

The heat wave that has kept much of Canada and the U.S. on edge for weeks has led to mass growth of the Greenland ice sheet.

Glaciers and ice sheets and their contribution to sea level rise

Dr. Michael Wenger

A comprehensive study with ETH / WSL participation shows how large the contributions of glaciers and ice sheets to future sea level rise will be.

Record melt in 2012 affects ice sheet today

Dr. Michael Wenger

The record melt of the Greenland ice sheet in 2012 continues to have an impact on the stability of the ice sheet today.

Lack of ice in the Arctic causes methane to escape

Dr. Michael Wenger

The lack of ice from glaciers used to cause methane gas to rise from the sea floor, which can happen again today.

Fossil plant remains reveal sensitive Greenland ice sheet

Dr. Michael Wenger

Well-preserved plant remains from ice cores at Camp Century show that the Greenland ice sheet is much more sensitive to warming than previously thought.
