It’s warming Mars too. The polar ice caps are melting there.
And there seems to be warming on Pluto.
That George Bush is just too darn dangerous!
Okay...here’s a follow up to that. One idea about how to make Mars habitable is to melt the ice caps, thereby freeing CO2 and H2O into the atmosphere. This would cause a runaway greenhouse effect freeing more CO2 from the regolith. This would in effect raise Mars’ atmospheric pressure to something that we could reasonably work in in a shirt-sleeve environment, except with breathing masks/air tanks. If the ice caps melt, with this process start?
