Is Al Gore an altruistic prophet trying to keep us all from frying ourselves with our wasteful, global-warming inducing ways? Or is he just a snake-oil salesman pushing global warming alarmism because it’s going to line his pockets? I pick No. 2. Here’s Gore last month speaking in Monterey, Calif. (emphasis added):

There are a lot of great investments you can make. If you are investing in tar sands, or shale oil, then you have a portfolio that is crammed with sub-prime carbon assets. And it is based on an old model. Junkies find veins in their toes when the ones in their arms and their legs collapse. Developing tar sands and coal shale is the equivalent. Here are just a few of the investments I personally think make sense. I have a stake in these so I’ll have a disclaimer there. But geo-thermal concentrating solar, advanced photovoltaics, efficiency, and conservation.

I think most reasonable people would call that a conflict of interest.
