If both Mars and Earth are experiencing global warming, then maybe there is a larger phenomenon going on in the Solar System that is causing their gl… - Anthony Watts

The emphasis this week seems to be on the sun, and the fact that maybe its really the sun which has been driving climate change after all. That's what I've been saying for years, because its just unrealistic to ignore the largest and single most important contributor to our planets energy balance and to only focus on made-made CO2 and nothing else.

"Global warming" suggests a steady linear increase in temperature, but since that isn't happening, proponents have shifted to the more universal term "climate change," which can be liberally applied to just about anything observable in the atmosphere.

I have to think that because NASA chose to co-author this paper [LaDochy et al., 2007] with researchers at California State University, that some of the statewide "global warming as man-made problem bias" crept into the thinking for the purpose of this paper, i.e. "we need another study to show that its getting hotter so action is justified".
