Camp Century, a U.S. military base built within the Greenland Ice Sheet in 1959, doubled as a top-secret site for testing the feasibility of deploying nuclear missiles from the Arctic during the Cold War. When the camp was ...

Scientists identify climate 'tipping points'

An international team of scientists have identified potential 'tipping points' where abrupt regional climate shifts could occur due to global warming,

Rising oceans - too late to turn the tide?

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean ...

Ice ages only thanks to feedback

Ice ages and warm periods have alternated fairly regularly in the Earth's history: the Earth's climate cools roughly every 100,000 years, with vast areas of North America, Europe and Asia being buried under thick ice sheets. ...

Trucks lose, ships win in warmer Arctic

Global warming will have a devastating effect on roads in the Arctic but open up tantalising routes for shipping, according to a study published on Sunday in the specialist journal Nature Climate Change.
