Journal It doesn't come easy's Journal: Sun's role in global warming may be underestimated
An announcement on EurekAlert says that at least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities. This has been claimed before. This is not to say that greenhouse gasses are off the hook, but it means that climate change models need to be adjusted accordingly. I would say another piece of evidence for increased solar output may have been found by the Mars Orbiter, where surveys show for three Mars summers in a row, deposits of frozen carbon dioxide near Mars' south pole have shrunk from the previous year's size, suggesting a climate change in progress (the Mars Orbiter report was also featured in this Slashdot submission).
