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

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. (Get an overview: "Global Warming Fast Facts".)

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.

Burn the witch.

Scientists have suspected in recent years that Mars might be undergoing some sort of global warming. New data points to the possibility it is emerging from an ice age.

NASA's Mars Odyssey orbiter has been surveying the planet for nearly a full Martian year now, and it has spotted seasonal changes like the advance and retreat of polar ice. It's also gathering data of a possible longer trend.

There appears to be too much frozen water at low-latitude regions -- away from the frigid poles -- given the current climate of Mars. The situation is not in equilibrium, said William Feldman of the Los Alamos National Laboratory.

"One explanation could be that Mars is just coming out of an ice age," Feldman said. "In some low-latitude areas, the ice has already dissipated. In others, that process is slower and hasn't reached an equilibrium yet. Those areas are like the patches of snow you sometimes see persisting in protected spots long after the last snowfall of the winter."

Climate change is a much, much bigger issue than the public, politicians, and even the most alarmed environmentalists realize. Global warming extends to Mars, where the polar ice cap is shrinking, where deep gullies in the landscape are now laid bare, and where the climate is the warmest it has been in decades or centuries.

"One explanation could be that Mars is just coming out of an ice age," NASA scientist William Feldman speculated after the agency's Mars Odyssey completed its first Martian year of data collection. "In some low-latitude areas, the ice has already dissipated." With each passing year more and more evidence arises of the dramatic changes occurring on the only planet on the solar system, apart from Earth, to give up its climate secrets.

The orbiter was designed to carry out observations for one Martian year (nearly two Earth years), but it has lasted much longer than its designers anticipated. Its mission was extended in 2001, and scientists have been able to use it to track seasonal changes on the red planet, as well as to pick up changes like the appearance of new boulder tracks.

The surveyor has also picked up new impact craters formed since the 1970s, which may mean age-estimating models need to be revisited. In addition, scientists have watched carbon dioxide deposits at Mars' south pole shrink for three consecutive Martian summers. They suggest there may be a climate change in progress.

Mars and Pluto are undergoing their own periods of global warming, according to multiple scientific studies. This has important implications for our own planet, and for Al Gore and liberal environmentalists as well.

On Mars, NASA and the California Institute of Technology's Jet Propulsion Laboratory report a prolonged period of surface warming, and the Martian icecap is steadily receding. According to scientists, "the fact that it is changing suggests that Mars may have major, global climate changes that are occurring on the same time scales as Earth's most recent climate shifts, including the last Ice Age." (emphasis added)

Pluto is undergoing a similar period of global warming, scientists report. According to a Massachusetts Institute of Technology release, "Pluto is undergoing global warming, as evidenced by a three-fold increase in the planet's atmospheric pressure during the past 14 years, a team of astronomers from the Massachusetts Institute of Technology (MIT), Williams College, the University of Hawaii, Lowell Observatory and Cornell University announced."

MKPD,Why are you posting in multiples,before anyone has time to respond?

Posting so much info will only discourage lesser intelligent mortals to take you up on what you say or believe.

Just wanted to give you multiple different angles from multiple sources. A consensus if you will.
