Climate models full of hot air
A paper recently published in the journal Remote Sensing has found that observations made by NASA’s Terra satellite in fact contradict a number of assumptions fed into alarmist computer models, including those of the United Nation’s IPCC. Dr. Roy Spencer used data from between 2000 through to 2011 to show that the Earth’s atmosphere is far more efficient at releasing energy to space than models have been programmed to believe.
If 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 modellers have theorised. Although it is generally agreed that emissions of carbon dioxide do not directly trap ‘much’ heat, 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.
What the data has shown is that atmospheric humidity and cirrus clouds are not increasing in the manner predicted by alarmist computer models – the result is climate forecasts that are warming substantially faster than the atmosphere. “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,” Spencer said in a press release.
