Global warming will even affect satellites - speeding them up, of all things

Because CO2 in the uppermost reaches of the atmosphere acts as a coolant, and because gas contracts when it cools, the greenhouse gas that is baking us on the ground will be slightly shrinking the total volume of our the atmosphere and thus reducing drag on some satellites.

As a result, those satellites will speed up a little bit (or, rather, slow down a little less), which will screw up calculations based on their orbits.

Interesting, eh? Nature just loves those unintended consequences.
