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.
