"More than two-thirds of the recent rapid melting of the world's glaciers can be blamed on humans, a new study finds.
Scientists looking at glacier melt since 1851 didn't see a human fingerprint until about the middle of the 20th century. Even then only one-quarter of the warming wasn't from natural causes.
But since 1991, about 69 percent of the rapidly increasing melt was man-made, said Ben Marzeion, a climate scientist at the University of Innsbruck in Austria."
