> Betting on sunspots to reverse a century of adding carbon to the atmosphere via fossil fuels is a bit of a long shot bet. What possible basis could you have for making this judgment? I dearly hope that folks aren't going to accept only the science that agrees with their previous public policy goals. In the face of new evidence, one's opinions are required to change. For my part, an ice age is more scary to me than a hot age. I can't quite tell if that's just because I personally hate cold weather or if my observation that humans seem to thrive more easily in warmer weather is a fact. Incidentally, that global warming happens is a sure thing. The magnitude and effects of global warming aren't any more of a sure thing than predicting sun spot activity.
