But a government can grow, grow, grow while pretending to solve the problem, failing, and "correcting" for the problem that caused them to fail.
The moral counterargument is that people should be allowed to decide for themselves and for their own government what is and is not a problem. If, under those basic conditions, no policy can work, then those policies are still immoral.
And the moral hazard counterargument is that "qui bono" often fits both sides. In this problem, there is certainly merit to the argument that the IPCC, politicians and scientists involved, the governments, and ... stand to benefit as well. Increased budgets, more people, bigger organisations, more experiments, more things to manage, more power to tell others what to do. Worse, this money and power will come at the expense of the "bootstraps" folk.
Bottom line: usually people on both sides of an argument believe what they want to believe. Exceptions exist, but not nearly as much as I thought when I was 16 years old.
This is why science should work in the hard, provable only, way. That any result can be duplicated by anyone who wants to do so, and anyone should be given the tools to convince themselves any given theory works. Climate science is a bit lacking on this front, to put it mildly.
