See the ice fields before they melt in Greenland

With global warming breathing down our necks it's time to start thinking ahead, so act quickly as this may be your one chance to see the ice sheet before they're gone. Two miles thick & broad enough to blanket an area the size of Mexico, Greenland's ice fields shape the world weather. Snow that fell a quarter of a million years ago is still preserved, if the ice sheet melts as its predicted to do in the future sea levels could rise as much as 21 feet. One of the best ways to see the ice fields of Greenland is to take a helicopter tour from the more temperate coast.
