A nine-year record of slush on the Greenland Ice Sheet
Abstract. Surface melt on the Greenland Ice Sheet (GrIS) has intensified in recent decades, accelerating GrIS mass loss. Slush (i.e., water-saturated firn or snow) is a key component of this system, y...

Even in total darkness, the Arctic is getting warmer — and clouds are part of the reason why.
A new study analyzed 26 years of winter data from Alaska’s North Slope, and revealed that increasing cloud opacity — clouds becoming thicker and denser — is trapping more heat near the surface.
