Reality Not Conforming to Computer Models
So the title of this article is a little sensationalist and, well, alarmist, but it does point to some very interesting research. Bottom line is that reality does not conform to the climate change computer models. We might want to consider attempts to radically alter how we live bases on the assumption that human sources of CO2 are harmful to the global climate.

New NASA Data Blow Gaping Hole In Global Warming AlarmismYou can read the PDF of the research in question here.
NASA satellite data from the years 2000 through 2011 show the Earth's atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed.
Study co-author Dr. Roy Spencer, a principal research scientist at the University of Alabama in Huntsville and U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer flying on NASA's Aqua satellite, reports that real-world data from NASA's Terra satellite contradict multiple assumptions fed into alarmist computer models.

New Paper “On the Misdiagnosis Of Surface Temperature Feedbacks From Variations In Earth’s Radiant Energy Balance” By Spencer and Braswell 2011I wonder how long it will take for this information to penetrate society to the same extent that angst about CO2 has?
“At the peak, satellites show energy being lost while climate models show energy still being gained,” Spencer said.
This is the first time scientists have looked at radiative balances during the months before and after these transient temperature peaks.
Applied to long-term climate change, the research might indicate that the climate is less sensitive to warming due to increased carbon dioxide concentrations in the atmosphere than climate modelers have theorized. A major underpinning of global warming theory is that the slight warming caused by enhanced greenhouse gases should change cloud cover in ways that cause additional warming, which would be a positive feedback cycle.
Instead, the natural ebb and flow of clouds, solar radiation, heat rising from the oceans and a myriad of other factors added to the different time lags in which they impact the atmosphere might make it impossible to isolate or accurately identify which piece of Earth’s changing climate is feedback from manmade greenhouse gases.
“There are simply too many variables to reliably gauge the right number for that,” Spencer said. “The main finding from this research is that there is no solution to the problem of measuring atmospheric feedback, due mostly to our inability to distinguish between radiative forcing and radiative feedback in our observations."
