Pretty disengenuious to come out with a study now justifying colder temperatures that were not projected in their original models that were used to justify the alarm of global warming. The fact that the study is being done by the people who are responsible for the temperature records we rely on for determining the validity of their alarm, is in itself alarming to say the least, as if James Hansen wasn't bad enough. Instead of trying to find out why the models are wrong they continue to prop up their failed hypothesis with more studies to explain away the failures of their original hypothesis, ain't science great.

Global warming not without cooler periods
U.S. scientists say people denying global warming due to short-term periods of cooling don't understand the statistical insignificance of such periods.
David Easterling of the National Climatic Data Center in Asheville, N.C., and Michael Wehner of the Lawrence Berkeley National Laboratory in Berkeley, Calif., said some Web sites and media articles have noted the average global temperature has not risen since 1998 and cite that as evidence against anthropogenic, or human-caused, global warming.
The researchers said although most climate scientists recognize the statistical insignificance of such short-term trends, some segments of the public pay attention to them. To quell such objections, they argue such short periods are not meaningful in the context of long-term climate change.
Easterling and Wehner said they have determined decade-long periods of cooling can occur even within a strong overall warming trend. The scientists said that due to natural variability, they expect some multi-year periods of cooling or stable temperatures to occur during the 21st century within longer-term periods of anthropogenic global warming.
The research appears in the journal Geophysical Research Letters.
