The author's attempt to distinguish himself from the right and from the left on this issue is sadly unimpressive.
The only relevant issue in regards to "An Inconvenient Truth" is whether or not the science behind it is solid. Unfortunately, the actual inconvenient truth of global warming is that there is absolutely no way to prove that mankind has a global, and significant impact on climate. The fact that human technology is not going to sit still while we continue to collect observations, the variables of the hypothetical human contribution to climate change are going to continue to change, thus making a scientific analysis of actual cause and effect impossible.
And while the author was correct about there being other reasons besides possible human impacts on climate to regulate emissions, the differences between what global warming proponents propose and what rationally conservative environmental policies propose are radically different. The liberal environmentalists envision a world where there are far fewer humans and very little industry. The rational and conservative environmentalists envision a world where technology and science offset human impact on the environment allowing for growth and development.
When you get right down to it - the liberal solution won't work without a central world government, and genocide of the world's poor. While the genocide might be unintentional - it would be inevitable because the wealthier nations would be unable to afford the expense of aiding the poorer nations. For the most part, the wealthier nations would be only steps away from poverty themselves. And the conservative solution would work either way - if humans are behind global warming, science will probably overcome the problems, but such science takes money to develop into practical technologies. Money that otherwise would be unavailable or misspent under the liberal plan. Or if global warming is not man made, then the conservative plan would help prepare mankind to deal with the consequences of natural climate change.
Liberals have proposed a lose-lose solution. Conservatives have a win-win solution.
