I'm going to quote this in it's entirety, courtesy of the National Review (audio can be found here)...
"Some people think that our planet is suffering from a fever. Now scientists are telling us that Mars is experiencing its own planetary warming: Martian warming. It seems scientists have noticed recently that quite a few planets in our solar system seem to be heating up a bit, including Pluto.
NASA says the Martian South Pole's ice cap has been shrinking for three summers in a row. Maybe Mars got its fever from earth. If so, I guess Jupiter's caught the same cold, because it's warming up too, like Pluto.
This has led some people, not necessarily scientists, to wonder if Mars and Jupiter, non-signatories to the Kyoto Treaty, are actually inhabited by alien SUV-driving industrialists who run their air-conditioning at 60 degrees and refuse to recycle.
Silly, I know, but I wonder what all those planets, dwarf planets and moons in our SOLAR system have in common. Hmmmm. SOLAR system. Hmmmm. Solar? I wonder. Nah, I guess we shouldn't even be talking about this. The science is absolutely decided. There's a consensus.
Now, before people get in a big huff about this, Thompson's point is simple...there is a lot of evidence that global warming trends are taking place elsewhere in our solar system, but the Al Gores of the world will tell you that NOBODY believes in this science...even though it is fact that these warming trends on other planets is absolutely happening.
As I said before, we need to have a lot of discussion and comparison of data before we can say that "there is a consensus" that global warming on Earth is humanity's fault and we are solely to blame for it. Too many scientists are finding other reasons for global warming, and we shouldn't deny them just because we'd rather stick our heads in the sand.
