sl149q writes: Whether you believe in Climate Change or Climategate the problem is that no one in the first or third world is really willing to actually pay enough to change things fast enough to make much difference. The bigger question is whether it is better to spend money to mitigate one problem (CO2) or solve other problems.
This from an article by Nigel Lawson in the WSJ article (http://online.wsj.com/article/SB10001424052748704107604574607793378860698.html) : "The reasons for the complete and utter failure of Copenhagen are both fundamental and irresolvable. The first is that the economic cost of decarbonizing the world's economies is massive, and of at least the same order of magnitude as any benefits it may conceivably bring in terms of a cooler world in the next century."
And: "The reason we use carbon-based energy is not the political power of the oil lobby or the coal industry. It is because it is far and away the cheapest source of energy at the present time and is likely to remain so, not forever, but for the foreseeable future."
And if we do need a conspiracy theory it is helpful to remember that 27 out of 50 of the worlds largest oil companies are state owned or controlled (http://www.energyintel.com/DocumentDetail.asp?document_id=245527).
