Martian Meltdown
Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist SaysHints ? Hints ?
No, it must be all the huge amounts of greenhouse gases we're pumping into the Martian atmosphere.
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.Again, suggests ? Controversial theory ? Now why would it be a controversial theory ? Huh.
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.Rapid warming ? I guess that would explain that Ice Storm we had here last month. You know, the one that knocked out power and heat for a week ? The vast majority of climate scientists ? Since when did science work on concensious ? Oh right, when the Enviromentalist Whackos, Communists, Dumbocrats and misc other Liberal nut-jobs decided so.
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.
Well that's a shocker. Without the Global Warming Boogy-man, they're out of funding and a job.
"His views are completely at odds with the mainstream scientific opinion," said Colin Wilson, a planetary physicist at England's Oxford University.
You'll notice he said "His views are completely at odds with the mainstream scientific opinion. Opinion is not fact. Opinion is not science.
"And they contradict the extensive evidence presented in the most recent IPCC [Intergovernmental Panel on Climate Change] report." (Related: "Global Warming 'Very Likely' Caused by Humans, World Climate Experts Say" [February 2, 2007].)
Evidence ? The title of the reference they use says 'Very Likely', as in not proven, not factual, in other words an opinion.
Amato Evan, a climate scientist at the University of Wisconsin, Madison, added that "the idea just isn't supported by the theory or by the observations."
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.
Planets' wobble but they don't fall down.
"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.
Most scientists think it is pure coincidence. Again an opinion. Not science.
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."
Oh crap ! So either way we're screwed !
Either the planet boils or the planet freezes !
Everybody Panic !
