"... to the extent it is sensible to speak of a mean temperature for Mars, the evidence is for significant cooling from the 1970's, when Viking made measurements, compared to current temperatures. However, this is essentially due to large scale dust storms that were common back then, compared to a lower level of storminess now. The mean temperature on Mars, averaged over the Martian year can change by many degrees from year to year, depending on how active large scale dust storms are."

Mars used to be a warmer, wetter place, but due to its small mass and the "skimming effect" of 2 moons, it has lost most of its atmosphere, resulting in a drop in temperature (Mercury is much closer to the sun than Venus, but because it has virtually no atmosphere, it is colder, on average, than Venus). However, the sun is warming all the planets more than it did billions of years ago, so that would also include Mars. It also appears to go through cycles of energy output, as well as sunspot activity, and we may be experiencing a high point at present, so that could explain it.

I have, in that the polar icecaps appear to have been larger in the past... to me, the indication of warming on two planets seem to point to the fact that the output of the sun has increased in the last 1000 years.

It's another "Inconvenient Truth" that Al ('I invented the Internet') Gore and his pack of rabid sycophants would like you not to know since it points out that 'Global Warming' isn't something that's man-made. And that little fact will cost him and his financial buddies billions (that's Billions, with a 'B') of dollars in lost investment revinue if it causes the industrialized west to abandon the Kyoto Accords..

Yep, the sun is going through a normal 1,500 cycle thats warming up every planet in our solar system and beyond.
Don't believe the lies!!!
