In this July 15, 2011 photo, atop roughly two miles of ice, technician Marie McLane launches a data-transmitting weather balloon at Summit Station, a remote research site operated by the U.S. National Science Foundation (NSF), and situated 10,500 feet above sea level, on top of the Greenland ice sheet. Climate scientists overwhelmingly agree that manmade greenhouse gases are warming the planet, accelerating the melt of Greenland's ice, and yet resistance to the idea appears to have hardened among many Americans. Why? "The desire to disbelieve deepens as the scale of the threat grows," concludes one scholar who has studied the phenomenon. Analysts now see climate as another battleground in America's left-right "culture wars." (AP Photo/Brennan Linsley) less
