Does EPA Have the Wrong Gas?

Over at MasterResource.org is an article looking at EPA’s Proposed Endangerment and Cause or Contribute Findings for Greenhouse Gases Under Sections 202(a) of the Clean Air Act, and wonders whether or not the EPA has set its sight on the correct gas. The EPA’s focus seems to be on carbon dioxide, but a very strong case can be made that the net effect of increasing atmospheric carbon dioxide concentrations may not be so bad (in fact, it may be quite good). So instead of risking the possibility that if they consider the climate impacts of CO2 alone they very well may not be able to build a case for an “endangerment to public health or welfare,” the EPA has lumped CO2 together with five other greenhouse gases thus watering down the positive aspects of CO2 with the potential negative ones from the other gases.

The MasterResource piece argues that to make a fair assessment of its effect on climate, CO2 should be unlumped and considered on its own.
