For more than a century it has been known that increasing the atmospheric concentration of carbon dioxide will eventually lead to a warming of surface temperatures, concentrated more in winter than summer, and more in mid and high-latitudes over land.

However it's also known that the integrated warming of southern Greenland was much greater for several decades in the early and mid-20th century than in the last decade.

With the exception of one year (2003) Greenland's recent temperatures aren't particularly unusual, nor are its rate of ice loss.

Global warning is not in a runaway. Satellite photographs published in Science magazine show that Greenland is losing .0004 percent of its ice per year, or 0.4 percent per century.

All modern computer models require nearly 1,000 years of carbon concentrations three times what they are today to melt the majority of Greenland's ice.
