Rising temperatures are fueled, in part, by declining cloud cover — which could be a potential climate feedback loop.

The cloud cover isn't what it used to be, and scientists say it is helping fuel Earth's hottest temperatures on record.

The key finding: Earth's albedo was the lowest since 1940, and that contributed about 0.2 degrees Celsius to record heat in ...

Greenland's ice sheet currently spans over 1.7 million square kilometers and is the largest freshwater reservoir in the ...

Arctic glaciers are leaking significant amounts of methane, a potent greenhouse gas. Glacial melt rivers and groundwater springs are transporting large volumes of methane from beneath the ice to the ...
