As we debate global warming, here's one piece of evidence that climate change may be coming from the Sun, not (entirely?) from man's activity on Earth: climate change is apparently happening on other planets.
Mars has seen a half-degree C increase in the last 40 years. And now, apparently, the iconic big red spot on Jupiter has gained two buddies; the first in 2006 and the second only more recently. Apparently this is due to
climate change on Jupiter.
