The rate of Arctic surface warming has reached 2 to 4 times the global average—a phenomenon known as "Arctic amplification." Traditional theories suggest that snow and ice melt reduce surface albedo, ...

The first color that comes to mind when thinking about Antarctica is a stark white, which makes sense, given the southernmost continent is generally buried in ice and snow. It has earned its ...

As summer wanes in the Northern Hemisphere, scientists are sounding the alarm over what could be one of the most extreme Arctic melt seasons in recorded history — a shift with potentially far-reaching ...

Proxy reconstructions indicate that sea level responded more sensitively to CO₂ radiative forcing in the late Pleistocene than in the early Pleistocene, a transition that was proposed to arise from ...

A Sandia National Laboratories study used previously unpublished data from GPS monitors to learn more about what’s decreasing the sun’s reflectivity in the Arctic. ALBUQUERQUE, N.M. — The Arctic, ...

The Arctic is warming at three to four times the global average. However, new research suggests the slowing of a key ocean current could reduce projected Arctic warming by up to 2 degrees Celsius by ...
