An evangelical friend of mine thinks Global Warming is a conspiracy of scientists to make a few bucks and control our lives. There may be some truth to that. Some people are angling to make money on carbon credits. Some bureaucrats like to use the power of government to act like a mini dictator.
But the flip side is that there's also money in global warming denial. Want to make a quick $10,000? Write articles undermining the IPCC report on global warming. Become a lobbyist for the fossil fuel industry.
Noam Chomsky claims in this speech (linked at the time stamp for those that don't want to watch it all) that the American Petroleum Institute has openly expressed that they are impressed with the health insurance lobbying efforts to screw over the American people and the success they had with that. They state openly that they plan to use the same model to undermine public opinion on global warming. These plans are being propagated by CEO's that know what scientifically minded people know. Global warming is occurring, it is likely the result of human activity, and there is significant risk that it could lead to massive death. But we have systemic constraints. They are obliged in the economic system we are in to maximize profits and this is how you go about doing it, even though that means potential catastrophe for our grandchildren.
