Why a ‘runaway greenhouse effect’ isn’t possible
“Runaway greenhouse theories contradict energy balance equations,” states Miklos Zagoni, an atmospheric physicist with 30 years of experience and a former researcher with NASA’s Langley Research Center. Just as the theory of relativity sets an upper limit on velocity, his theory sets an upper limit on the greenhouse effect, a limit which prevents it from warming the Earth more than a certain amount. The conclusions are supported by research published in the Journal of Geophysical Research last year (2007) from Steven Schwartz of Brookhaven National Labs, who gave statistical evidence that the Earth’s response to carbon dioxide was grossly overstated. It also helps to explain why current global climate models continually predict more warming than actually measured.
The equations also answer thorny problems raised by current theory, which doesn’t explain why “runaway” greenhouse warming hasn’t happened in the Earth’s past. The new theory predicts that greenhouse gas increases should result in small, but very rapid temperature spikes, followed by much longer, slower periods of cooling — exactly what the paleoclimatic record demonstrates.
