Today NASA's Jet Propulsion Laboratory has a story from the Mars Global Surveyor. Among new impact craters and new gullies formed in Martian sand dunes, the Surveyor has also found that:
...for three Mars summers in a row, deposits of frozen carbon dioxide near Mars' south pole have shrunk from the previous year's size, suggesting a climate change in progress.
Let's stop and think about this for a second. The most logical and accepted explanation for global warming besides being caused by human activities is that it is caused by natural and periodic changes in the output of the sun's radiation (a logical assumption, considering that global climate change has been going on for billions of years, i.e. the numerous worldwide 'ice ages' and the resulting warming that ended them). This theory that the sun has periodic changes in its output that would cause climate change could be most easily tested by evaluating the climate of other planets in the solar system. If Mars is warming up slowly, too...
But let's also not forget that the global average temperature on Earth has only risen 1.1 degrees F over the past 140 years. Don't forget...
Oh, and I'm sure that once hurricane Rita strikes the US the mainstream media, the occasionally uninformed average person, and the occasional European government will scream and howl about how global warming is causing hurricanes to grow in number and intensity. I have already thoroughly debunked this obvious untruth here. And if you want to see for yourself, check out NOAA's site directly.
