Possible 1,000-kilometer-long river running deep below Greenland’s ice sheet
Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern coast of the island. Updating ice sheet models with this open valley could provide additional insight for future climate change predictions.

Energy at risk: the impact of climate change on supply and costs
The energy sector is the biggest source of greenhouse gas emissions and therefore the main responsible of the observed human-caused changes in the climate system, but it is also vulnerable to the changing climate. To understand the future climate impacts…
Ice loss due to warming leads to warming due to ice loss: a vicious circle
The loss of huge ice masses can contribute to the warming that is causing this loss and further risks. A new study now quantifies this feedback by exploring long-term if-then-scenarios. If the Arctic summer sea-ice were to melt completely, a…
Cold vibrations: Researchers to study the movement of thawing Arctic permafrost
With rising temperatures in the Arctic, communities in Alaska’s North Slope Borough are seeing the ground beneath their feet melt away. “Climate change is thawing the frozen soil,” said Ming Xiao, associate professor of civil and environmental engineering at Penn…
Seabird response to abrupt climate change 5,000 years ago transformed Falklands ecosystems
Orono, Maine — The Falkland Islands are a South Atlantic refuge for some of the world’s most important seabird species, including five species of penguins, Great Shearwaters, and White-chinned Petrels. In recent years, their breeding grounds in the coastal tussac…
Coastal permafrost more susceptible to climate change than previously thought
