UPDATE: I've updated this story in a new blog post here.

For the first time in its history the new edition of The Times Comprehensive Atlas of the World was forced to redraw its map of Greenland, reflecting the fact that 15 percent of the island's permanent ice cover—about 115,830 square miles/300,000 square kilometers, or an area the size of Ohio—has melted in the past 12 years. (So did they draw the North Atlantic a little bigger?)

Other anthropogenic changes reflected in the Times Atlas:

  • The breaking up of the Antarctica ice shelves: The atlas's new Antarctica image shows the breaking up of the Larsen B ice shelf and Wilkins ice shelf, along with the ice bridge that once joined it to Charcot Island.
  • The shrinking of seas and lakes: The level of the Dead Sea has dropped 40 feet/12 meters in the last 12 years, mainly due to draining water from the Sea of Galilee and diverting it to the Jordan River.
  • The Aral Sea, which has shrunk by 75 percent since 1967.
  • The drying of rivers. Most years the Colorado River never reaches the Gulf of California due to damming, irrigation, evaporation, and water diversion to Salt Lake City and Los Angeles. In Mongolia, the Ongyin Gol river is diverted for gold mining. These and other rivers shown as 'intermittent' on the latest atlas could dry up entirely by the next edition in 2015.
