Why would governments support the theory of potentially disastrous man-made climate change? It was a combination of the success of the environmental Left — in particular activist non-governmental organizations — in stoking the concerns of the electorate, and of the desire of bureaucrats and policy-makers to stay relevant, busy and in power. This in turn gave them an interest in supporting the NGOs’ radical message, which was amplified by government funding, and by allowing them into the policy-making process. The policy process became self-feeding.

The environmental movement has also been astonishingly successful in co-opting education systems, and highly skillful at exploiting universal psychological tendencies to social conformity and deference to “authority”. The suggestion that climate change is primarily a “moral” problem has been a masterstroke, of which the masterstroker is Al Gore.
Invoking morality is a powerful weapon in shutting off debate. It employs the so-called “psychology of taboo” to place some claims — for example, that climate change may be natural, beneficial, or practically unstoppable — beyond the pale. Those who promote such notions must therefore be evil, or psychologically unbalanced, or in the pay of powerful corporations.
