This whole debate would be hilarious if it wasn't so serious. The most famous global warming alarmist, James Hansen, is a fraud and a bit of a nutjob. He testified in the uK that the heads of major energy companies should be prosecuted as enemies of mankind or some such nonsense. That is the guy who basically invented this whole fraud, whch was them picked up by Al Gore who saw a convenient hobby horse to ride. Since the science is woefully inadequate to support Hansen's outlandish predictions, they hit on this notion of claiming a "consensus" of scientists support it and anyone who objects is the equivalent of a nazi. Of course, as outlined in this thread and elsewhere, many prominent scientists either dismiss Hansen's predictions out of hand or point out that his work does not support his conclusions.
This is a two point exercise. Point one is for govenrment to get control of a vast area of the economy, eg manufacturing, energy and utilities. That goal will soon be complete, and you will begin to notice the effect in your utility bills, as they double and triple. Watch for liberasl to angrily denounce greedy utility companies and insist on price controls. Point two is to bind us in international agreements regulating emission of greenhouse gases. This will transfer control of the US economy to the "international community" and is the endgame for the faile dNorth-South dialogue of some 30 years ago. The object then, as now, is to transfer money from taxpyers of the US to rich elites in third world countries, all of course unde th4e guise of fairness, equality, socialjustice, saving the planet and whatever other bromides they can find. This is a longtime gola of obama, who also backs legislation requiring a vast expansion of US foreign aid.
It's interesting that there has been a near total media blackout on the fact that the House is voting on this far-reaching bill Friday. Democrats know that voters will be apoplectic with anger when they realize what has happened, and they do not want to risk an uprising before the votes are safely in hand.
As for the science, consider that these are the same people who have objected for decades to missile defense on the grounds that it couldn't possibly work. Well, it does work and we're mighty lucky that Reagan blew them off.
