MARTIAN KYOTO? 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."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....Abdussamatov's work, however, has not been well received by other climate scientists. -- Kate Ravilious, nationalgeographic.com, 02/28/07
