loss of 97% of its surface ice cover.
"Five days later, an estimated 97 percent of the surface area was thawing. Nearly the entire surface of the ice sheet, from the very edges to the very center, saw some thawing."
"Ice cores from Summit show that melting events of this type occur about once every 150 years on average. With the last one happening in 1889, this event is right on time," says Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data. "But if we continue to observe melting events like this in upcoming years, it will be worrisome."
The last such melt event occurred in 1889, according to data from ice cores, and scientists say they would expect such an event about every 150 years
While Greenland's ice isn't going to be melting completely and catastrophically flooding low-lying areas of the earth in the next few decades (sea level is only rising about 3 mm per year or 1.2 inches per decade at present), the risk later this century needs to be taken seriously.
