Cool times ahead for the upper atmosphere
Not all parts of the atmosphere will warm as carbon dioxide and other greenhouse gases accumulate above Earth. A new computer modeling of the upper atmosphere shows that the thin air high above the planet's surface should cool substantially -- an effect that may help some satellites stay in orbit longer.
Most climate projections for the next century have focused on how accumulating greenhouse gases will affect the troposphere and the stratosphere, the two layers closest to Earth. This is the first time researchers have used complex computer models to predict the effect on the two highest regions, the mesosphere ...
