In no particular order, there are the Leftist economists for whom global
warming represents a supreme example of market failure (as well as a wonderful opportunity to suggest correctives), UN apparatchiks for whom global
warming is the route to global governance, Third world dictators who see guilt over global
warming as providing a convenient claim on aid (ie, the transfer of wealth from the poor in rich countries to the wealthy in poor countries), Environmental
activists who
love any issue that has the capacity to frighten the gullible into making hefty contributions to their numerous NGOs, Crony capitalists who see the immense sums being made available for «sustainable» energy, Government regulators for whom the control of a natural product of breathing is a dream come true, Newly minted billionaires who find the issue of «saving the planet» appropriately suitable to their grandiose pretensions, Politicians who can fasten on to CAGW as a signature issue where they can act as demagogues without fear of contradiction from reality or complaint from the purported beneficiaries of their actions.
