Surface lakes cause Antarctic ice shelves to 'flex'
The filling and draining of meltwater lakes has been found to cause a floating Antarctic ice shelf to flex, potentially threatening its stability.

Ice volume calculated anew
Researchers have provided a new estimate for the glacier ice volume all around the world, excluding the Greenland and Antarctic ice sheets. Their conclusion: previous calculations overestimated the volume of the glaciers ...
Sand from glacial melt could be Greenland's economic salvation
As climate change melts Greenland's glaciers and deposits more river sediment on its shores, an international group of researchers has identified one unforeseen economic opportunity for the Arctic nation: exporting excess ...
Ice melt in Greenland and Antarctica predicted to bring more frequent extreme weather
Last week, rivers froze over in Chicago when it got colder than at the North Pole. At the same time, temperatures hit 47℃ in Adelaide during the peak of a heatwave.
Melting ice sheets may cause 'climate chaos' according to new modelling
The weather these days is wild and will be wilder still within a century. In part, because the water from melting ice sheets off Greenland and in the Antarctic will cause extreme weather and unpredictable temperatures around ...
Cracks herald the calving of a large iceberg from Petermann Glacier
Cracks in the floating ice tongue of Petermann Glacier in the far northwest reaches of Greenland indicate the pending loss of another large iceberg. As glaciologists from the Alfred Wegener Institute, Helmholtz Centre for ...
Ocean expedition to West Antarctic Ice Sheet seeks to reveal climate history
The West Antarctic Ice Sheet in the Amundsen Sea off Antarctica could play a pivotal role in future sea level rise, but many questions remain unanswered, scientists say.
Novel hypothesis goes underground to predict future of Greenland ice sheet
The Greenland ice sheet melted a little more easily in the past than it does today because of geological changes, and most of Greenland's ice can be saved from melting if warming is controlled, says a team of Penn State researchers.
Near-term ocean warming around Antarctica affects long-term rate of sea level rise
In the West Antarctic Ice Sheet, which is particularly susceptible to influencing sea levels, rates of mass loss are especially sensitive near the point at which a glacier or ice shelf transitions into a regime of self-sustained ...
Ancient asteroid impacts played a role in creation of Earth's continents
The heavy bombardment of terrestrial planets by asteroids from space has contributed to the formation of the early evolved crust on Earth.
