If there is one thing we know about 'global warming' it is this: The science behind the global warming theory is neither conclusive nor definitive. While scientific dispute about the causes of recent global warming continues, attempts to proclaim a scientific consensus are self-debilitating. There is none. More and more scientists, on the contrary, dare to speak out about it.

Still the true believers march onward peddling their product, forced to rebrand their item of choice because those little things called "facts" remain stubborn things...

Clearly when he penned Federalist 63 James Madison was not contemplating "global warming." However when one reads the document these words seems rather apropos:
“There are particular moments in public affairs when the people, stimulated by some irregular passion, or some illicit advantage, or misled by the artful misrepresentations of interested men, may call for measures which they themselves will afterwards be the most ready to lament and condemn. In these critical moments, how salutary will be the interference of some temperate and respectable body of citizens, in order to check the misguided career, and to suspend the blow meditated by the people against themselves, until reason, justice, and truth can regain their authority over the public mind?"

In this post, Nick Loris from the Heritage Foundation puts the global warming alarmism in proper perspective: there is no scientific consensus on climate change and implementing an extremely costly policy that may have little or no effect on temperature would would be ill-advised and dangerous.

Let us not march blindly into the era of environmentalism in which environment (or perhaps the irrational claims of environmentalists) is placed ahead of men and their freedom.

As my father used to remind me time and again... think before you act.
