Greenland Ice Melt, Measured By NASA Satellites, Reaches Unprecedented Level

But the data from three independent satellites this July, analyzed by NASA and university scientists, showed that in less than a week, the amount of thawed ice sheet surface skyrocketed from 40 percent to 97 percent. ...
... When Son Nghiem of NASA's Jet Propulsion Laboratory observed the recent melting phenomenon, he said in the NASA press release, "This was so extraordinary that at first I questioned the result: Was this real or was it due to a data error?"
