But new research offers some hope if we are able to keep climate change under control.

The Earth has had at least five major ice ages, and humans showed up in time for the most recent one. In fact, we’re still in it.

A newly discovered city-size lake might contain a history of the world's largest ice sheet in East Antarctica since its earliest beginnings.

Liquid water below the ice determines how fast an ice stream flows. As the ice sheet gets thinner, more of that salty groundwater could rise.

Melting lakes on ice shelves can widen cracks within them - new research shows how these lakes change across the world’s largest sheet.

Sea ice is thinning at an alarming rate. Snow is shifting to rain. And humans worldwide are increasingly feeling the impact of what happens in the seemingly distant Arctic.
