Global Warming: 1,600 Years of Ice in Andes Melted in 25 Years

Evidence in a "spike in global temperatures" was recently proven from a "remarkable find at the margins of the Quelccaya ice cap in Peru," home of the world's largest tropical ice sheet. Reportedly, despite the glaciers being 1,600 years old, it has only taken the last 25 years to melt it.

Of greater immediate interest, Dr. Thompson and his team have expanded on previous research involving long-dead plants emerging from the melting ice at the edge of Quelccaya, a huge, flat ice cap sitting on a volcanic plain 18,000 feet above sea level.

Several years ago, the team reported on plants that had been exposed near a meltwater lake. Chemical analysis showed them to be about 4,700 years old, proving that the ice cap had reached its smallest extent in nearly five millenniums.

In the new research, a thousand feet of additional melting has exposed plants that laboratory analysis shows to be about 6,300 years old. The simplest interpretation, Dr. Thompson said, is that ice that accumulated over approximately 1,600 years melted back in no more than 25 years.
