We are warming up MARS!!!

More like, intergalactic planetary warming!!!

And this is new information? Someone would be dumb to say that there is no way the sun can heat things up. What is equally dumb is for others to sit on their hands and deny any responsibility for what humans are putting into the air that does contribute to gloabal warming.

This couldn't go in either of the other 2 threads discussing this subject matter?

3/3/2007 10:03:51 AM

Of course not. It's more fun to start new threads about topics that need more sensationalizing by both sides.

greenhouse effect on mars would be a good thing

I am pretty sure this is caused by John Edwards being such a faggot.

"The solar irradiance began to drop in the 1990s, and a minimum will be reached by approximately 2040," Abdussamatov said. "It will cause a steep cooling of the climate on Earth in 15 to 20 years."

Guess we'll know pretty soon, relatively speaking.

Imagine sports on Mars with one third the graviational pull. 30 foot dunks. 90 foot long jumps, 24 foot high jumps, 1200 yard golf drives.

P.S. I want to climb Olympus Mons.

Global warming on Mars is being caused by this guy.

I mean look how huge he is. Just imagine the size of his SUV!!!!

Wait, I thought the latest climate denialist theory was the cosmic ray flux is increasing. I'm not sure how this would make Mars warmer since the composition of the two atmospheres are different.

It's funny how every scientific outlier in the climate debate is amplified through the echo chamber of the internets. I'm sure I could at least make Fox News if I wrote a crazy bullshit paper and submitted it to some obscure shitty journal.

"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 (from the SUN, perhaps?) 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 (more like unmarsed) 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."

"Dust blamed for warming on Mars 18:00 04 April 2007 NewScientist.com news service David L Chandler Scientists have been puzzling over the cause of dramatic global warming on Mars, which has made parts of the south polar ice cap disappear in recent years. The answer, it seems, is blowing in the wind: the planet's famous reddish dust. Using global circulation models similar to those used to analyse Earth's changing climate, a team led by Lori Fenton of NASA's Ames Research Center in California, US, found that Mars seems to have warmed by about 0.65° Celsius in the three decades since the Viking mission first provided detailed mapping of the whole planet. That warming can be explained entirely by the scouring away of light-coloured dust from darker areas of the surface, causing an increase in the absorption of solar radiation. This effect is greatly amplified by positive feedback: The warmer ground causes stronger winds, which in turn scour away more of the light dust and lead to greater warming. Team member Paul Geissler, a planetary geologist at the US Geological Survey in Flagstaff, Arizona, says the mechanism can account for the rapid warming that has been seen in the disappearing polar caps, which are turning directly from solid to vapour at a rapid rate (watch an animation showing Mars's south polar cap change from 1999 to 2005). Global dust stormThe overall distribution of dark and light areas on Mars has clearly changed since Viking (watch an animation of the surface reflectivity changes over the entire planet). The new modelling shows that the heating produced by those changes is "the same order of magnitude" as that required for the rapid removal of the polar ice, Geissler says. At some point, the model predicts the winds will build up so much they will trigger a global dust storm, redistributing the light dust over most of the surface and starting the process over again. While the dust redistribution may be unique to Mars, Earth may have analogous feedback processes that can amplify changes in surface reflectivity – in this case, mostly based on changes in sea ice and snow cover. But although some scientists argue that the global warming on Mars shows there must be some external cause to Earth's warming – such as a change in solar output rather than human-caused increases in greenhouse gases – Geissler says the new research undercuts that argument. "What our work shows is that the warming on Mars that we know has been going on for some time has a local cause [on Mars]," he told New Scientist. The new work could have a significant impact on understanding past changes in the Martian climate. "This is the first attempt to quantify the impact of these surface changes," Geissler said. From now on, "when we study Mars' climate, we need to keep track of the surface [reflectivity] and its interaction with climate.""

Oh, and if it is the sun that is the cause for GW, then why hasn't there been an increase in measured radiation flux over the past 30 years?
