so, what's causing the warming on Mars...probably us...

Mars is being hit by rapid climate change and it is happening so fast that the red planet could lose its southern ice cap, writes Jonathan Leake.
Scientists from Nasa say that Mars has warmed by about 0.5C since the 1970s. This is similar to the warming experienced on Earth over approximately the same period.
Since there is no known life on Mars it suggests rapid changes in planetary climates could be natural phenomena.
The mechanism at work on Mars appears, however, to be different from that on Earth. One of the researchers, Lori Fenton, believes variations in radiation and temperature across the surface of the Red Planet are generating strong winds.
In a paper published in the journal Nature, she suggests that such winds can stir up giant dust storms, trapping heat and raising the planetâ??s temperature.
Fentonâ??s team unearthed heat maps of the Martian surface from Nasaâ??s Viking mission in the 1970s and compared them with maps gathered more than two decades later by Mars Global Surveyor. They found there had been widespread changes, with some areas becoming darker.
When a surface darkens it absorbs more heat, eventually radiating that heat back to warm the thin Martian atmosphere: lighter surfaces have the opposite effect. The temperature differences between the two are thought to be stirring up more winds, and dust, creating a cycle that is warming the planet.

Come on, you know it's those damn martians poluting their planet, didn't you see "war of the worlds".

I hear Al Gore has a private Shuttle Craft now.........lol

Have a good one!:s4:

Comparing the red planet to earth is like comparing apples to oranges.We are causing global warming and whats happening on mars is something totally differant.

It doesn't matter if global warming is man made or a natural phenomenon. Fact is that it's happening and we have too much population on our coast lines to ignore it. It wouldn't matter back in the day cause we'd just move. :P

true hardcore so we have to do something about it and cleaning the enviroment is nothing but a good thing for us and our kids

I'd say it does matter because we need to know where to focus our efforts to curb it, if possible. Either way though, I'd be glad if we stopped putting poisonous shit into the air; I mean global warming or no, nobody can tell me that's a good idea.

Mars finally got news that Bush made plans to have a manned mission there and is trying to off itself first.

I told my bio teacher about how al gore has zinc mines on his property that he collects royalties from, and like most global warming lunatics he basically just said "hah, well were all not perfect"

god, global warming is the biggest scam to ever be invented because its so easy to manipulate it to look "scientific" when its not. this will distract the activists from protesting about the real issues

What if your wrong?what if we didnt do anything about global warming and 100 years down the road we cant even live on this planet what then?Were fucked.This is the only home we have and to play russian roulette with the earth is very dangerous to us.It wont effect me but my kids kids will wonder why we didnt try to do something the worse that can happen is we clean up the earth and whats wrong with that?
