Two different planets with two different weather and climate patterns. As I said in an earlier post, and let me add, with the atmosphere being as thick as it is on Earth, I believe the waste matter from the fossil fuels used to power new machinery and create electricity helped trap heat in Earth's atmosphere, which adds to global warming. Also in regards to the southern polar cap on Mars melting, this can't happen with a Martian temperature and thin atmosphere. It's surface would have to be warmed in order for this to happen.

That doesn't make sense. Is the sun pointed more directly at Mars? I'm no astrophysicist, but your explanation sounds like a load of crap. If there's planetary warming on one planet due to the sun, it's going to at least happen on planets which are closer to the sun.
It seems like you're trying to jam the square peg of human activity causing global warming into a round hole.
Another explanation for GW is that in '79, we switched the paint used on monitoring stations. See the following transcript:

Also, the linked blog, presents a general study of temperature monitoring stations. It shows (quite convincingly) that when many were originally placed, they were nowhere near human activity. Now, those same stations are located in parking lots, near air conditioning units and other sources of heat which interfere with their accurate readings. Here are quite a few documented cases.
