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.

Ask Galileo.
