Arctic Melting, Greenland Ice Sheet, Global Warming

Excellent information from "wagmc" on MSNBC "Environment" discussion group.......thanks.

"We find that the current Greenland warming is not unprecedented in recent Greenland history. Temperature increases in the two warming periods are of a similar magnitude, however, the rate of warming in 1920-1930 was about 50% higher than that in 1995 - 2005."

Johannessen, et al. Recent Ice-Sheet Growth in the Interior of Greenland. Science DOI: 10.1126/science.1115356

These two very recent studies both support over 30 studies in the last 4 years that indicate clearly that:

current warming is neither catastrophic nor unprecedented
Greenland ice sheets are growing
Arctic temperatures are tied to major ocean temperature oscillations, which in turn are closely correlated with changes in solar output
