Mars warmup implies solar, not human, cause for global warming
It appears that the dire things Al Gore has been warning about Earth warming up, which he says are caused by mankind, have been happening on Mars too. Which humans have been causing the Maritan warming, Al? It looks just as "severe" as the warming on Earth.
If nothing else, this gives weight to the idea that Al Gore might not be from this planet at all.
Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says

Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes have a natural—and not a human- induced—cause, according to one scientist's controversial theory.
Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere.
Mars, too, appears to be enjoying more mild and balmy temperatures.
In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row.
Habibullo Abdussamatov, head of the St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun.
"The long-term increase in solar irradiance is heating both Earth and Mars," he said.
Solar Cycles
Abdussamatov believes that changes in the sun's heat output can account for almost all the climate changes we see on both planets.
Mars and Earth, for instance, have experienced periodic ice ages throughout their histories.
"Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance," Abdussamatov said.
By studying fluctuations in the warmth of the sun, Abdussamatov believes he can see a pattern that fits with the ups and downs in climate we see on Earth and Mars.
Abdussamatov's work, however, has not been well received by other climate scientists.
Re: Mars warmup implies solar, not human, cause for global warming
Yes,we know that global warming is being caused by the sun.
Yes, we know that global warming has human causes.
Long story short, it's not one or the other, it's both. Global warming can be directly correlated with increased industrial activity, and thus the increased produciton of greenhouse gases. Furthermore, we know the effects of greenhouse gases on the trapping of radiation within the planet. Causation + correlation= solid hypothesis. I don't see why anyone want's to disporve global warming. No harm can come from more environmentally friendly policies.

That depends entirely on the policies.
Many, if not most, environmentalists are 'watermellons' -- green on the outside, red on the inside. "Global Warming" is their excuse to do whatever they can to reduce economic activity -- a notion supported by their 'solutions' to the 'crisis', which deal almost exclusively with 'reducing' Western (and especially US) emissions while ignoring the same from the developing world, especially China and India.

Response to the thread starter.
What does mars have to do with what's going on on Earth? Two completely un-related planetary systems. Mars had been cooling does that mean Earth should also be cooling. If mars warms does that mean earth must warm? What's the cause and effect of mars to earth?
Oh the common denominator, the sun of course, only there has been no increase in solar output in the last 40 years. Hence clearly whatever is happening is strictly independent of the sun and is a "local" phenomena limited to that planetary system.
So unless you are drawing a cause and effect between these two planets, your entire thread premise is moot.

Planets' Wobbles
The conventional theory is that climate changes on Mars can be explained primarily by small alterations in the planet's orbit and tilt, not by changes in the sun.
"Wobbles in the orbit of Mars are the main cause of its climate change in the current era," Oxford's Wilson explained. (Related: "Don't Blame Sun for Global Warming, Study Says" [September 13, 2006].)
All planets experience a few wobbles as they make their journey around the sun. Earth's wobbles are known as Milankovitch cycles and occur on time scales of between 20,000 and 100,000 years.
These fluctuations change the tilt of Earth's axis and its distance from the sun and are thought to be responsible for the waxing and waning of ice ages on Earth.
Mars and Earth wobble in different ways, and most scientists think it is pure coincidence that both planets are between ice ages right now.
"Mars has no [large] moon, which makes its wobbles much larger, and hence the swings in climate are greater too," Wilson said. No Greenhouse
Perhaps the biggest stumbling block in Abdussamatov's theory is his dismissal of the greenhouse effect, in which atmospheric gases such as carbon dioxide help keep heat trapped near the planet's surface.
He claims that carbon dioxide has only a small influence on Earth's climate and virtually no influence on Mars.
But "without the greenhouse effect there would be very little, if any, life on Earth, since our planet would pretty much be a big ball of ice," said Evan, of the University of Wisconsin.
Most scientists now fear that the massive amount of carbon dioxide humans are pumping into the air will lead to a catastrophic rise in Earth's temperatures, dramatically raising sea levels as glaciers melt and leading to extreme weather worldwide.
Abdussamatov remains contrarian, however, suggesting that the sun holds something quite different in store.
"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."
I commend you though for finally using a credible source.

You know, I was thinking the same thing, and I came across this video this morning.

I wonder what the implications of this supposed phenomena would be on Global Warming. It makes it seem almost inevitable.

I always find it amusing when people make such a claim. First of all, the warming on Mars is REGIONAL not global and it happens every year due to the fact that Mars has longer and more intense seasons than Earth. Not to mention the fact that 95.72% of the atmosphere on Mars is Carbon Dioxide. But hey, why check up on the facts when you can take a cheap shot at Al Gore instead.
