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.Imagine that. The sun is heating both Mars and Earth. That isn't to say we shouldn't try to conserve and that we shouldn't try to be good stewards of our earth's resources, but the fact that the sun warms the Earth, along with Mars, is certainly an Inconvenient Truth.
"The long-term increase in solar irradiance is heating both Earth and Mars," he said.
