Heroes of Antarctic exploration have played a crucial role in research that suggests the area of sea ice around Antarctica has barely changed in size in 100 years.
Freakishly high temperatures in the Arctic driven by heat-packed oceans and northward winds have been reinforced by a "vicious circle" of climate change, scientists said Thursday.
Antarctic winter sea ice has once again broken the record for maximum extent. On September 12, the coverage measured 19.619 million square kilometres, the highest since satellite records began.
Recently NASA reported that this year's maximum wintertime extent of Antarctic sea ice was the largest on record, even greater than the previous year's record.
Two key climate change indicators—global surface temperatures and Arctic sea ice extent—have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite ...
Polar bear numbers could drop a third by mid-century, according to the first systematic assessment, released on Wednesday, of how dwindling Arctic sea ice affects the world's largest bear.
The melting of sea ice will significantly increase Arctic precipitation, creating a climate feedback comparable to doubling global carbon dioxide, a Dartmouth College-led study finds.
Last year, the Earth sweltered under the hottest temperatures in modern times for the third year in a row, US scientists said Wednesday, raising new concerns about the quickening pace of climate change.
Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder have reported. Analysis of satellite ...
The melting of sea ice in the Arctic is well on its way toward its annual "minimum," that time when the floating ice cap covers less of the Arctic Ocean than at any other period during the year. While the ice will continue ...
