After seeing portions of Greenland's glaciers break off into the North Atlantic, Nancy Pelosi opined: "It wasn't caused by the people of Greenland -- it was caused by the behavior of the rest of the world."  Maybe, just maybe, it was caused by the repeated natural warming and cooling of the earth.  And maybe Greenland isn't melting at all, says Investor's Business Daily (IBD):

  • Richard S. Lindzen, professor of atmospheric science at the Massachusetts Institute of Technology (MIT), says "the evidence so far suggests that the Greenland ice sheet is actually growing on average" and that a "likely result of all this is that increased pressure is pushing ice off the coastal perimeter of that country."
  • As Patrick J. Michaels, senior fellow in environmental studies at the Cato Institute, points out, satellite data published in the November 2005 issue of the journal Science showed Greenland was losing about 25 cubic miles of ice per year; dividing that by Greenland's 630,000 miles of ice, the island was losing ice at the rate of 0.4 percent per century.


  • Ian Howat of the University of Washington published another paper in the February 2007 issue of Science reporting that the rate of melting of two of the largest glaciers had slowed "to near zero, with some apparent thickening in areas on the main trunk."
  • Howat notes that Greenland was about as warm or warmer in the 1930s and '40s, before the SUV, and many of Greenland's glaciers were smaller than they are now; this was a period of rapid glacier melting worldwide followed by an expansion during a colder period from the 1950s to the 1980s.
