Sentinels of climate change

Pictures say a thousand words, right? Sometimes images say more about climate change than any story can. So In that vein, we've just launched a new interactive "Global Ice Viewer" that lets you explore what's been happening to Earth's ice cover lately.

We feature stunning time-lapse movies and dramatic before and after images of glaciers, sea ice and continental ice sheets around the globe. Take a look for yourself here.
