New NASA Data Blow Gaping Hole In Global Warming Alarmism 27 / 28 July 2011

The study, by the University of Alabama, based on Satellite Data claims that "Global Warming" caused by carbon trapping heat in the atmosphere is so minimal as to be negligible. The research, if noted by Carbon model proponents is sure to be hotly disputed.

As I reported recently, the Daily Mail, reported on a press release by the University of East Anglia, saying that most of the temperature DATA used to correlate with carbon levels in the polar ice, on which global warming claims are based, was destroyed by scientists in the 1980s, British media also reported on great inaccuracies in climate change claims involving the Himalayas, and other regions. The Daily Mail, and other media also recently reported that Earth is set to enter a mini-ice age, due to a temporary lack of Sun Spots (a phenomena discovered by Galileo centuries ago, which then lead to a 2 degrees centigrade reduction in temperatures). Media claiming climate science was in peril include: Daily Mail, the Times and Sunday Times, and the Telegraph in Britain, the first and last still claiming global warming as real.

The most recent discovery, that the computer models were wrong, would not surprise the  columnists of these papers, which have for years cited the completely inaccurate short and medium term climate forecasts of the British weather servide, since climate change variables were introduced.

The alternate view of climate change is that it is constant and consistent, and more recently caused by soil changes, urbanization and astronomical phenomena such as sun spots etc.

University of Alabama, USA has released the following statement to the Press, July 26th 2011, according to a source cited by the Yahoo News article (Forbes hosted on Yahoo)

"Climate models get energy balance wrong, make too hot forecasts of global warming

HUNTSVILLE, Ala. (July 26, 2011) — Data from NASA’s Terra satellite shows that when the climate warms, Earth’s atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to “believe.”

The result is climate forecasts that are warming substantially faster than the atmosphere, says Dr. Roy Spencer, a principal research scientist in the Earth System Science Center at The University of Alabama in Huntsville.

The previously unexplained differences between model-based forecasts of rapid global warming and meteorological data showing a slower rate of warming have been the source of often contentious debate and controversy for more than two decades.

In research published this week in the journal “Remote Sensing”, Spencer and UA Huntsville’s Dr. Danny Braswell compared what a half dozen climate models say the atmosphere should do to satellite data showing what the atmosphere actually did during the 18 months before and after warming events between 2000 and 2011.

“The satellite observations suggest there is much more energy lost to space during and after warming than the climate models show,” Spencer said. “There is a huge discrepancy between the data and the forecasts that is especially big over the oceans.”

Not only does the atmosphere release more energy than previously thought, it starts releasing it earlier in a warming cycle. The models forecast that the climate should continue to absorb solar energy until a warming event peaks. Instead, the satellite data shows the climate system starting to shed energy more than three months before the typical warming event reaches its peak.

“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.”

For this experiment, the UA Huntsville team used surface temperature data gathered by the Hadley Climate Research Unit in Great Britain. The radiant energy data was collected by the Clouds and Earth’s Radiant Energy System (CERES) instruments aboard NASA’s Terra satellite.

The six climate models were chosen from those used by the U.N.’s Intergovernmental Panel on Climate Change. The UA Huntsville team used the three models programmed using the greatest sensitivity to radiative forcing and the three that programmed in the least sensitivity."
