The Arctic has changed at a faster rate than the rest of the planet. Clouds impact the surface energy budget and, thus, the melting or growth of land- and ocean-based ice. Many Arctic clouds are "mixed phase," consisting ...

Clouds play a role in warming the Arctic and coinciding decreases in sea ice, but it is a complicated story. Using data from three Arctic sites, scientists studied the relationships among temperature, water vapor, and how ...
