Global warming on Mars.

Earth is not the only planet experiencing warmer temperatures, reported a February 28 National Geographic News online article entitled "Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says."

"Mars, too, appears to be enjoying more mild and balmy temperatures," the article noted. "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."

What is causing this warming? National Geographic quoted Habibullo Abdussamatov, head of space research at Pulkovo Astronomical Observatory in Russia, as saying that a "long-term increase in solar irradiance is heating both Earth and Mars." But the article also quoted Oxford University planetary physicist Colin Wilson as saying that "[Abdussamatov's] views are completely at odds with the mainstream scientific opinion."

Though the effect of changing solar intensity on planetary temperatures may be considered controversial, surely no one would quibble with the fact that carbon-dioxide emissions on Earth cannot be causing global warming on Mars.
