You're confusing sharlatans with scientific fact and pretending their the same thing. This may be the worst strawman you've ever written. Mann said nothing which is not verifiable scientific fact. Climategate never happened (your sources are lying to you) - the only scandal there was the crime of stealing private citizens emails and then using out of context quotes to lie about what was in them.

But I can see why you would dislike this reality - it's not gaia punishing America -it's the inevitable consequences of fossil fuel burning. And you fear admitting that, because if you do - you have nothing in your libertarian arsenal to argue against the obvious conclusion: that teh fossil fuel companies should be liable for the cost of rescue and repair operations.

It's pretty much needed to, governments can't afford it anymore. The US uses a mandatory insurance program to fund flood relief- it's bankrupt. The floods are worse than can be planned for - even by actuarialists.
