A new study has shown that decreasing carbon dioxide levels in the atmosphere led to a phenomenon of increased global cooling one million years ago.

Climate change means ice, where polar bears are most at home, is melting earlier in the year and so polar bears have to spend longer on land, scientists say.

LOS ANGELES: NASA has developed a new forecasting tool that can predict which cities will be affected as different portions of ice sheets melt due to global warming

Bonn - As climate change drives up temperatures, Earth comes ever closer to dangerous 'tipping points' that could accelerate global warming beyond our capacity to reign it in, scientists warned at

A geothermal heat source called mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet, a NASA study has found.

Aparna Pande, director of Hudson's India Initiative, said that weak states and contested sovereignties across the Himalayas have induced a number of regional actors to seek deeper physical and econ

Up to four times more coastal glaciers in Greenland are at risk of accelerated melting than previously thought, say scientists who have mapped the region's coastal seafloor and bedrock beneath its

CALGARY, Alberta (Reuters) - Arctic sea ice may be thinning faster than predicted because salty snow on the surface of the ice skews the accuracy of satellite measurements, a new study from the Uni

Melting ice is causing coastal waters in Greenland to become less saline, which may in turn affect marine life as well as the global ocean currents that keep Europe warm, a study warns.
