Greenland’s warming trend

Sen. James Imhoff (R-fantasyland) has claimed

Greenland has COOLED since the 1940’s!

In fact, current temperatures in Greenland — a poster boy for climate alarmists – are COOLER than the temperatures there in the 1930s and 1940s, according to multiple peer-reviewed studies.

Yes, you heard me correctly. Greenland has COOLED since the 1940s! A fact the media and global warming activists conceal.

Greenland reached its highest temperatures in 1941, according to a peer-reviewed study published in the June 2006 issue of the Journal of Geophysical Research. And, keep in mind that 80% of man-made CO2 came AFTER these high temperatures.


Well, Sen. Imhoff’s statement flies in the face of what we can see with our own eyes: Greenlanders are now growing broccoli and the native population can no longer use their dogsleds for transportation.

The study Imhoff cites actually showed that the apparent cooling was reported from 2 weather stations in southern Greenland. This is explained by a local weather phenomenon called North Atlantic Oscillation. One part of Greenland which is not included in the NAO has shown marked warming. A scientist from the University of Colorado has shown that, after a warm spell in the 20’s and 30’s, Greenland has now been warming for the past 20 years, and the ice is certainly melting:

For each of the past 17 years, Steffen has spent one month at a remote research site called Swiss Camp, located 300 miles north of the Arctic Circle in Greenland. He monitors the changing ice sheet through a network of global positioning systems and weather stations, which have recorded a dramatic rise in temperatures since the mid-1990s.

“When we came here in 1990, the first two, three years were actually colder than normal. Then in 1994, 1995, it started to warm steadily and since then, we’ve had a temperature increase during the winter months of 4.5 degrees centigrade, 8.1 degrees Fahrenheit, which is very large, the largest temperature increase on earth,” he said.

The rising temperatures feed what scientists call a “positive feedback loop.” As the air warms, it melts ice on the sea and snow on land. This exposes more water and land to the sun. Those surfaces in turn absorb more of the sun’s heat, leading to more snow melt and ice melt.

“When you look at our satellite analysis, we can see the melt area of Greenland over 30 years has increased by 30 percent,” Steffen said.


Last year, satellite data collected by NASA scientists revealed Greenland is losing 100 billion tons of ice each year, more than it is gaining from snowfall in the interior. Steffen and others have also detected a new, faster movement of the ice sheet, causing the glaciers to dump more ice into the ocean, where it melts and contributes to sea-level rise.
