Greenland's ice sheet covers an area of about 1.7 million square kilometers (656,000 square miles). In recent decades, higher temperatures and warmer seawater have caused the sheet to melt more rapidly during the summer. Though snowfall can help to counteract this ice loss, melting is still happening at a faster rate than snow is being added. We've collected some awesome videos on this topic. Watch them now to learn more.
