Another one bites the dust: ------------------- Climate Models Fail at Antarctic Warming Predictions Note: this is a NASA illustration for the purpose of this story, it is not from the peer reviewed paper. There is a a peer-reviewed study in the April 5th issue of the journal Geophysical Research Letters. It is by Andrew Monaghan of the National Center for Atmospheric Research in Boulder, CO. “This is a really important exercise for these climate models,” he said. Monaghan and his team found that while climate models projected temperature increases of 1.4 degrees Fahrenheit (0.75 degrees Celsius) over the past century, temperatures were observed to have risen by only 0.4 F (0.2 C). ”This is showing us that, over the past century, most of Antarctica has not undergone the fairly dramatic warming that has affected the rest of the globe,” Monaghan said. The gap between prediction and reality seemed to be caused by the models overestimating the amount of water vapor in the Antarctic atmosphere. “ ”The research clearly shows that you can actually slow down sea-level rise when you increase temperatures over Antarctica because snowfall increases, but warmer temperatures also have the potential to speed up sea-level rise due to enhanced melting along the edges of Antarctica,” Monaghan said.The gap between prediction and reality seemed to be caused by the models overestimating the amount of water vapor in the Antarctic atmosphere. The cold air over the southernmost continent handles moisture differently than the atmosphere over warmer regions. But they fail to recognize that there may be a volcanic heat source as well such as the volcanic mounatin range comprising much of the Antarctic Peninsula, including volcanoes such as the Seal Nunataks around the Larsen Ice shelf and under the Ross Ice Shelf here.
