Associated Press: Warmer air, less frigid water and gravity may combine to make parts of Antarctica's western ice sheet melt far faster than scientists had thought, raising sea levels much more than expected by the end of the century, according to a new study.
New physics-based computer simulations forecast dramatic increases in melting in the vulnerable western edge of the continent. In a worst case scenario, that could raise sea level in 2100 by 18 to 34 inches (46 to 86 centimeters) more than an international...
