Greenland http://kunc.org en Greenland, Antarctic Ice Is Melting Faster http://kunc.org/post/greenland-antarctic-ice-melting-faster Superstorm Sandy sparked a lot of interest in rising sea levels when it swept across the Northeast last month and flooded parts of the coast. Over the next century, more water — and higher sea levels — could come from melting ice in Greenland and Antarctica. How much has been unclear.<p>But now scientists have developed a much clearer view of how quickly that ice has been melting over the past two decades.

The second photo, taken on July 12, shows nearly the entire land mass — 97 percent — blotched in a red hue.<p>In a typical year, only about half of the Greenland ice sheet undergoes this kind of melting before it later refreezes.
