The upper levels of the ocean have never been this hot. Blame the end of La Niña and the ever-present heating effect of climate change.

The UN's final IPCC report warns that drastic action must be taken immediately, but staving off disaster is within humanity's grasp.

Researchers have isolated viable microbes from melting permafrost after tens of thousands of years. But don't worry; they infect only amoebas.

Antarctica's sea ice recently shrank to its lowest extent since satellite records began more than 40 years ago.

Thwaites Glacier in West Antarctica, known as the Doomsday Glacier for the role its melt could play in global sea level rise, is melting more slowly than previously estimated, new research finds. But the glacier is still in trouble.

What animal species will survive projected future droughts, rising temperatures and habitat loss?

Earth's climate is warming dramatically, and the signs are all around us, from vanishing glaciers to zombie viruses awakening in melting permafrost.

Scientists are getting a better handle on how fast Greenland's ice is flowing out to sea. Old models that used Antarctica as a baseline were way off the mark.

Although models accurately predicted the evolution of the Arctic storm, scientists were surprised to see just how much sea ice thickness decreased in the storm's aftermath.
