Didn't you see that SUV thing that NASA sent to Mars to collect rocks and little animals? That thing drove all over the planet, polluting the air and causing Martian global warming. We should be ashamed.

No one really knows why Mars may be warming up, not even the experts at NASA. We can't even say for certain that it is warming as there isn't enough data yet to be sure.
It seems likely that some parts of the planet are warming whilst at the same time other parts are cooling. The south polar ice cap has been observed to be advancing whilst the north polar ice cap has been retreating.
Partly this is seasonal but it seems there are other factors involved and the most likely explanation are the duststorms that sweep across the entire surface of the planet for several days or weeks at a time. There was one such storm a couple of weeks ago. These duststorms whip up huge amounts of dust which act like clouds and trap heat close to the Martian surface, at the same time the actual surface of Mars becomes darker and so it absorbs more heat (dark surfaces absorb heat, light ones reflect heat).
One thing that we do know is that it's not the Sun. We have very accurate instruments that constantly monitor the Sun, both on Earth and from space and the amount of heat being produced by the sun has fallen very slightly in recent decades.
There are other planets and moons that are warming as well but in each case it's due to a unique set of circumstances. Many planets and moons show little, if any, change in temperature and there are several that are cooling.

TThe warming right now on Mars is believed to be related to dust storms that are going on right now. Mars has dust storms seasonally. the overall trend is cooling, and that will resume as soon as the dust storms end. This is all within Mars' normal seasonal cycle, which is much more complex than the earths'. This is the second time this has happened since the Viking landings. The only people who have ever suggested it is a form of global warming are the skeptics, or deniers if you prefer, and people speaking in jest. What distinguishes Global Warming is it does not fit our seasonal pattern, or our more long term pattern of glacier advance and retreat. We are already way outside of both patterns, which are even better known and understood than those of Mars.

Global Warming can be divided in to two sources, that is warming caused by human activity, and warmiing caused by factors other than human activity.
On the planet Earth the component of warming that is caused by human activity is rather large.
On the Planet Mars any causes of warming will be factors other than man.
Just because there are causes of Global Warming other than human activity, does not mean that human activity does not make a significant contribution to Global Warming.

Our sun is going through an increased output of solar activity, subsequently solar flairs and sunspots have increased. This increase is due to last for another 10 -15 years.
Thermal images of our solar system show that EVERY planet and moon is slightly warmer by about 3 degrees!
This is a natural event, it has happend before and will happen again.
It has nothing to do with the myth that is global warming.

You got your argument wrong. The argument isn't that the moon is warming up, it's that Mars is warming up.
Anyway, Mars is believed to be warming up due to an increase in Martin dust storms. It's not connected in anyway with the warming here on Earth.
http://news.nationalgeographic.com/news/2007/04/070404-mars-warming.html
In fact, the only way it =could= be related is through changes in solar activity. But since there has been no increase in solar output for at least forty years (and possibly seventy), when warming on Earth has been fastest, that seems astronomically unlikely.

The warming of small parts of Mars are not related to warming on Earth.
http://environment.newscientist.com/channel/earth/climate-change/dn11642
samIam: there are over 6 billion people on Earth, and each one of us burns a ton of fuel per year on average. Most of this fuel is in the powerplant that provides electricity to your house, some of it is gasoline for your car. As a result, 20 billion tons of carbon dioxide are released into the atmosphere each year (carbon dioxide is heavier than just carbon alone). The amount of excess carbon dioxide that is causing global warming is about 14 billion tons per year. So it is certainly possible that humans are causing global warming.

Climate fluctuations and solar intensity differences on the Earth are due to fluctuations in the our orbit known as the Milankovitch cycles. http://en.wikipedia.org/wiki/Milankovitch_cycles
These cycles theoretically have resulted in the glacial and interglacial periods. We are currently in a warming trend but unless Mars has an Orbit trend identicle to ours, I don't think it would matter much if it is warming or not. There are other cycles of the sun too but I personally don't need any percieved warming on Mars to make me doubt human caused "significant" global warming.

Mars has dust storms and wind. It is so windy on Mars that the dust storms trap heat which heats up the whole planet and melts the ice caps. This is not what happens on earth. On earth there is so much of the man made poison C02 that the heat from the sun gets trapped on the earth and this c02 demon won't let it go. So earth is slowly turning into a hell.

Most of the planets and moons are not warming. So it's not the Sun.
Mars may be warming a bit, likely due to giant dust storms, unique to Mars.
On Earth scientists have proven it's mostly humans. Here's a good picture, from the Source below:

Just in case you don't know "anthropogenic" means man made.
