cyberdude611 -> NASA confirms global warming on Mars (4/30/2007 11:53:19 AM)
According to NASA, Mars is warming just as fast as Earth. Since there is no life on Mars, it proves the fact that planetary warming at the speed we see on Earth CAN be a naturally occuring phenomenon. -------------------- Climate change hits Mars 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 planet’s temperature. Fenton’s team unearthed heat maps of the Martian surface from Nasa’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. http://www.timesonline.co.uk/tol/news/uk/article1720024.ece

hehe, and the comments are great! I liked this one: with the fate of our solar system hanging in the balance, al gore should spearhead an expedition to set the ignorant martians straight before they ruin everything: 1. no cars 2. no lightbulbs 3. no toiletpaper 4. no farting 5. build more shade i agree with all of the above, this is clearly george bush's fault. let's impeach him. [:D][:D] FirmKY

What's unbelievable is how so many global-warming alarmists are climbing all over themselves trying to create new theories to try to explain this away. "It CAN'T have anything to do with the reason that the Earth is warming up - it just CAN'T!!!"

Damnit KY ... the Democrats voted to send the Mars lander too ...

"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." I have no idea whether our presence is influencing climate changes or not....But since you all seem capable of reading and I have, up to this point been willing to usually concede that you might even possibly understand the material.....Since this is a quote from the article why would any one of intelligence equate what is happening on Mars and then compare it to Earth?

Because the global warming crowd (and Al Gore) claimed that warming cannot occur naturally at the speed we are seeing it happen on earth right now. Therefore, humans are playing a role in causing increases in temperature. Yet, we are seeing global warming naturally occuring on Mars at the same speed.

Such an observation is not saying there is a direct link between warming trends on earth and mars. It is certainly an interseting finding and may* have relevance but the neither article nor the report it refers to is "proof" that earthly warming has the same cause as warming on mars, as you so desperately want it to be. To the contrary, as this thread has brought repeatedly to your attention, the article itself says - " The mechanism at work on Mars appears, however, to be different from that on Earth." Z.

o.o just some food for thought; ice core samples* have shown extremely turbulent weather patterns in the past few thousand years. to keep this short and sweet, basically the consistant weather we are having right now is a freak occurance. id find an article on it, but im a bit strapped for time. * for those of you who dont know what these are, they are samples of ice taken from polar caps. in these samples scientists are able to see weather patterns, and determine what compounds were in the atmosphere in the past(for example, they can clearly see when the industrial revolution occured, based on the change in what was floating around the atmosphere and eventually landed in the poles. neto, yes?) through these they can also see patterns of cooling/heating based on how much melted or frozen snow there is. melted snow is clear, and usually occurs when there are long periods of heating, and frozen snow had many bubbles in it(whitish color) which indicates that it was very cold at the time. its all pretty cool stuff, worth looking up

Yes but for entirely different reasons...By your logic if a planet is devoured when it's sun supernovas then that period of extreme quick "warm up"...lol.... the planet would endure is natural and can show that planets have the capability of warming up "naturally."...Which again is in no way related to what the earth is currently experiencing....Both you and Firmy are pretty sharp dudes and I would think you would realize how this article does not support nor condemn the theory of global warming. Again I will state it is difficult if not impossible to positively pinpoint our pollutants as the cause of the warming trend seen ....I think it is a distinct possibility....Seems not to be a totally whacked theory...I wonder if you just despise the messenger so much that you can't even begin to think about the possbilities that there might be some credible evidence backing this position. But as far as making and conducting an argument this is not the material that would further your cause....Lame at best.

You are correct in that it proves or disproves nothing in and of itself, I'll grant you. But to state that it has - no - relevance I think is a bit premature, and seems to be making a judgment without a clear understanding of the mechanisms involved. Prejudgement either way is always a dangerous thing in science. FirmKY

meatcleaver -> RE: NASA confirms global warming on Mars (4/30/2007 2:25:03 PM)
This is not news. Since Mars is not earth and has a different atomosphere and no biological life, at least what we know of, the two can't be compared. Everyone knew the planets are warming because the sun is at the height of one of its cycles. It wouldn't be revelatory news to hear Mars was warming faster than earth because the atomospheric chemistry is different. Until enough studies be done on the climate of Mars and enough models made in comparison with earth, comparison is rather meaningless.

NASA scientists also point to the fact that their satillites have registered zero temperature change in the Earth's atmosphere over the past 30 years. The only increase is being experienced on the surface. They have also pointed to the fact that the sun is going through a magentic polar shift and a hotter cycle, which is generating an increased amount of radiation and heat. In fact NASA scientists say this the most violent they have ever seen the sun. There are temperature increases throughout the solar system on every planet. It only makes sense that the Earth would also be victim of some increased heat and radiation. The sun will reach the peak of this cycle in 2012 but will take 20-30 years to cool back down to its previous level. So I don't see how you are going to prevent the earth from warming some. In fact, Im surprised we arn't warming up faster.

Thank God we don't live on the surface of the planet.
