AB 1058, which would give the California Air Resources Board power to regulate CO2 as a pollutant is facing stiff opposition. So if you live in California, you might want to write in support of it. The final vote is this Thursday.

I support AB 1058.
I believe humanity is having a large effect on the global climate, and unfortunately the changes are subtle enough that people can try to ignore them. Even though the 1990's were the warmest decade on record and many regions are experiencing more extreme weather patterns. Some regions are getting noticeably more rain in some areas, and others much less, not to mention the increasingly severe floods, tornados, and hurricanes. Yet given all that people still desperately want to cling to their inefficient SUVs which are only exacerbating the problem.
However I was talking with an opponent to AB 1058 and they didn't like the idea of the CARB having the power to add additional taxes to gasoline.
My counter suggestion is to use the idea of feebates. Require that monies collected by the CARB be redistributed back to the population.
For instance an extra fee attached to automobiles that get less than 15 mpg could then be given as a rebate to autos that get more than 40 mpg. Or even better, subsidize mass transit, or perhaps they could even pay people to bicycle or walk to work instead of driving.
Also I suspect it would be a good idea for the CARB to start some education campaign to actually explain the link between burning gas and global warming.
