How science kicks the crap out of Global Warming

Richard Lindzen of MIT has released a new paper disproving a central tenet of Global Warming. According to fear mongers, radiation from the Earth into space should decrease as the surface temperature increases (see the eleven predictive models in Lindzen's paper). This is a non-feedback system (i.e. no feedback mechanism--small deviations in input result in this case in larger deviations in output. In this case a small increase in surface temperature would result in a larger increase in surface temperature later presumably due to the excess CO2 in the atmosphere trapping that radiated heat. . .runaway temp increase! Sound the alarm! Manbearpig!).
Lindzen's paper, however, using data compiled for over 20 years from the Earth Radiation Budget Satellites (ERBE(xperiment)) shows that as surface temperature increases, radiation from Earth to space. . .wait for it. . .INCREASES!
Yes, that's right sports fans. As the Earth gets hotter, it radiates more heat into space, which in turn cools it down towards the norm again. That's negative feedback at work. Makes sense doesn't it?
So much for the dreaded hockey stick, drowning polar bears, swampy Manhattan, single digit (or multi for that matter) temp increases over the next hundred years due to human activity, and other such nonsense. It's going to take a lot more water vapor and methane (oh yeah and I suppose CO2) for the system to heat up like the global warming scaredy pants imagine. And even then it won't "run away." The system is stable! Deviations from the norm result in negative deviations back in the direction of the norm. We're not at a tipping point. Not even close. It ain't built like that.
It will be interesting to see which scientists will look at this in detail and which will continue to suckle at the IPCC.
It is a good day to be B-A.
