But the most significant way in which humans contribute to global warming is in the production of greenhouse gases.

That may not be the case.

Research has shown that the focus on just carbon dioxide as the dominate human climate forcing is too narrow. We have found that natural variations are still quite important, and moreover, the human influence is significant, but it involves a diverse range of first-order climate forcings, including, but not limited to the human input of CO2 (e.g. see NRC, 2005 and Kabat et al, 2004). These other forcings, such as land use change and from atmospheric pollution aerosols, may have a greater effect on our climate than the effects that have been claimed for CO2

If that view is correct, we may incurring huge costs for limited benefits.

For a sample of the peer reviewed research on forcings other that CO2 (273 posts so far) see:
