text: This very question was the focus of an article in Popular Mechanics about 6 months ago. The glacier in Greenland has been melting twice as fast as it was, only two years ago. The magazine predicted if all the glaciers of the world melted, the result would be a loss of a 100 miles of  coastline in from its present location, all over the world. Small islands would disappear altogether. The increase of water has resulted in a slower jet stream and cooler temperatures despite the claim of global warming. In fact, it's the greenhouse gases that are causing the glaciers to melt in the first place.
