Thinks it can be explained through solar means because both Earth and Mars are warming right now. He also thinks that in 15-20 years the Earth will cool significantly.

Just goes to show the long reaching ramifications of George Bush's evniornmental policies....he is even screwing up Mars

I think that I actually remember seeing this on a Discovery Channel program a few years ago. Not sure if it's exactly the same thing, they seem very similar.

Well, I'm confused. If solar irradiance has been dropping since the 90s, then why is Mars supposedly warming? And is the whole planet warming? Or just part of it? This would imply that the sun is not the cause of either Earth or Mars warming.

This confuses me as well.

I think one thing is clear though. There is clearly not consensus in the scientific community regarding global warming.

That's true. It's such a complex topic scientifically that I'm not sure we'll ever have a consensus though. Especially when politics is interwined in it. I think most scientists believe that the earth is warming, we just don't know if humans are contributing significantly.

I'm not sure anybody has actually measured a drop in solar irradiance so I don't know why he says that. The article is too short on details.

Everyone knows that Manbearpig's magical flatulence is causing global warming. Geez people.
