The other big factor is the reflectance of snow, known as albedo. Albedo is defined as the ratio between how much light a material reflects -- to the amount of incoming light. We give different ...

The last few years have seen some of the smallest sea ice coverage, plus a look into the continued spring melt on the ...

Snow-covered area in March across the western United States was 8 percent below average, ranking seventeenth in the 25-year satellite record. Snow cover duration was just above the twenty-fifth ...

Dartmouth researcher Gabriel Lewis measures reflectivity on Greenland's ice sheet during a 2016 research expedition. According to a Dartmouth research paper, a reduction in fresh snowfall has ...

The disappearance of sea ice changes the surface albedo, i.e. the reflectivity of the Arctic Ocean, but also removes the insulation between the atmosphere and the ocean surface and affects ...

When they hit land, they release their water in the form of heavy rain or snow. In Greenland, extreme rainfall from these rivers can accelerate the ice sheet’s melting. But when temperatures are ...

As climate change effects become more pronounced, a new report from NASA and the National Snow and Ice Data Center (NSIDC) highlights a chilling reality: Arctic winter sea ice has ...
