extreme heat sets in.
In July 2012, when the extreme heat hit the island, ice started melting. At one scientific research station, flags planted in the once-frozen snow fell over. Supply planes couldn’t land on the ice runway because it was melting, too. Satellite images of the island show that 97 percent of the island’s surface ice melted for a short time this summer. That’s a new record, says Earth scientist Marco Tedesco of the City University of New York. He uses satellite data to study changes in the Earth’s climate. He said that this year’s melt in Greenland was greater than in any other year since satellites started observing seasonal changes in the island’s ice. He worries that with global warming, such melts may occur more frequently. He is afraid that a warmer world will lead to a greener Greenland.
