NASA: Quiet Sun Cooling Earth’s Upper Atmosphere

2009-12-18

Richard Moore

For the first time, researchers can show a timely link between the Sun and the climate of Earth’s thermosphere, the region above 100 km, an essential step in making accurate predictions of climate change in the high atmosphere.

While this warming has no implications for climate change in the troposphere, a fundamental prediction of climate change theory is that the upper atmosphere will cool in response to increasing carbon dioxide

The climate model argument would say that since Co2 reflects more heat back to Earth, less is radiating out to the upper atmosphere, and hence it would cool. That has nothing to do with upper-atmosphere cooling from reduced Sun activity. This new result means that climate modelers should subtract out the Sun’s contribution to upper-atmosphere cooling, and not try to claim that portion as a confirmation of their presumed Co2-effect.
