I honestly don't know who to believe in this highly politicized matter.

I think since this is ultimately about protecting the environment, there are probably more pressing issues we could address since global warming isn't as well understood as we would like it to be.

We should look at how China is terribly polluted, or how other emerging industries an bursting populations will effect our society and prepare for that. We also have a massive fishing crisis that needs to be addressed, land use that is killing our ecosystem, deforestation and massive erosion in the middle east and elsewhere, big issues that could effect us much faster than an excess of Co2. Let's think about our air and water quality. If that means reducing emissions, so be it, but there are other things we should be focusing on than the Co2 content of our emissions.
