Global warming on Mars (not caused by humans).
 

Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says

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 space research at 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.

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.

Are you questioning the opinions of the man who invented the internet?

I wouldn't dare :) :)

Of course it's not 100% man-made effects. However, we and other animals i.e. cows, are causing more damage. Also if you look back it seems to be on a twenty year cycle.

how come you don't post the whole article ? let me continue it for you


Abdussamatov's work, however, has not been well received by other climate scientists."

His views are completely at odds with the mainstream scientific opinion," said Colin Wilson, a planetary physicist at England's Oxford University.

"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].)

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.

"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."

Things like this crack me up

But on Earth it MUST be caused by a 84 Cutlass Capri...

The global warming is the biggest conspiracy in history...
It's used to stuff us with "green" taxes and shit..

There are two danish scientist who's been saying that it's all caused by the sun for YEARS!

Thread title cracked me up.

Don't ever blame the Cutless... it was the high hair and aqua net days in the 80's

Jesus - this is an adult webmaster board - what the fuck does everyone have a hard-on for proving or disproving global warming here for???

when it's too hot, people don't want to jerk off...it could mean the end of our industry!!!!!!!!!!!@####

First of all 3 years of data is nothing. We have 120 years of data for Earth and Bush says "The jury is still out".

Even if this theory is correct and humans are less responsible for global warming doesn't mean we don't try to reduce our part. I mean you don't get diagnosed with HIV then say "Fuck it, I might as well go contract syphillis".

"Habibullo Abdussamatov"

the guy from Borat? lol

Didnt you get banned?

Silly kids - tricks are for polititicans!


MAN MADE GLOBAL WARMING IS A TOTAL LIE!

To state anything else - is to prove uselessness - since THERE IS NO SCIENCE that proves it. PROPONANTS are either completely duped or in a position to profit from their remarks.

Just ask the guy who invented the internet how much his company stands to profit selling carbon offsets? Or, any of the so-called scientists who lie about global warming - how they get their funding? Or why the global warming hysteria is worth half a billion dollars a year and growing...

Furthermore...

If ANYONE with a brain capable of researching some simple facts on their own.. they may find as manny as twice the number of decensting scientists and those who say global warming is caused by man.

or... that the EARTH warms and cools itself at REGULAR intervals. There are HISTORICAL ACCOUNTS of WINE GRAPES being grown around the 5th century AD in ENGALND and vast farms on GREENLAND. And ICE SAMPLES from the Arctic have provided supporting eveidence to the theory that the Earth warms and cools on a 1500 year cycle.

or... that ALL of man's carbon production (industry and cars) only accounts for less than 5% of ALL carbon production.

FACT: the earth is warming.
FACT: the earth will cool.
FACT: there is NOTHING you can do to cause it or stop it.

Who cares about Mars...

mars will explode sooon do go to mars people :)))

FACT: NASA Rovers are found on both Earth and Mars.
CONCLUSION: NASA Rovers are causing global warming.

What he said

Fact is there are lots of different greenhouse gasses, CO2 being only one of them. Methane for example is a greenhouse gas 23 times more potent than CO2. The methane gas contained in and released by the siberian tundra/permafrost has a lot bigger effect on the weather/climate than CO2 released by humans will ever have.
