Sentinels of climate change
Chip off the old (ice) block

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.
