Surprise!  Climate change is affecting Mars, as well… last time I checked there wasn’t any life there, so this is a shocking development (well, not really) that implies that human beings might not be the bane of the Earth after all.

Scientists from Nasa say that Mars has warmed by about 0.5C since the 1970s. This is similar to the warming experienced on Earth over approximately the same period.

Since there is no known life on Mars it suggests rapid changes in planetary climates could be natural phenomena.

The mechanism at work on Mars appears, however, to be different from that on Earth. One of the researchers, Lori Fenton, believes variations in radiation and temperature across the surface of the Red Planet are generating strong winds. [Emphasis mine]

Maybe Al Gore can fly there and give a speech about global warming… and not return.
