I wasn't refering to the warming of Mars. But you may want to look here.. There is no 'global' warming on Mars, but just on the southern pole. Mars has a much more elliptic orbit than the earth, which contributes significantly to its seasons, which are caused by the tilt of the rotational axis on the earth. Also, so far the warming has been observed for only three seasons on Mars.
1) After looking at here the answer should be clear.
2) Look here.
3) Look here. The CO2 level is increasing dramatically. Burning fossil fuels releases CO2. Pretty much clear, eh?
Now, if you put all these facts together: global temperatures are increasing (1), it is increasing abnormally (2), we do emit carbon dioxide into the atmosphere (3), CO2 does cause a greenhouse effect, what else is needed to convince anybody that humans cause global warming?
Pretending that there are other causes, or that is not happening at all is just wishful thinking.
When you look here you will see that the temperature increased since 1910, but stagnated between the 1940s and 1980, but then rised again. This seems to fit the storm count data very well.
