I dont understand the republican train of thought to just do nothing until we are in an event that could possibly wipe us out because they "dont believe it". Best case scenario is that we are not causing climate change. That doesnt mean we are not effecting it by pouring more Co2 into the atmosphere. Cons remind me of the people in the Dust Bowl times that didnt want to believe their farming habits were effecting the soil until it was too late.
So many things to spend 6 or $8Trill on -- I guess you'd have to decide whether 1 or 2 degC by 2100 is a true enough crisis to hobble economies and cut-back discretionary spending. The ORIGINAL estimates were for 6 or even 8 degC by 2100 -- since revised way the hell down. In that sense -- skeptics have already prevailed.
And you better be DAMNED certain that 1 or 2 deg per century is TRUELY unprecedented in the record of climate history. Which honestly can't be assessed from what we ACTUALLY know since before the time of thermometers.
RIGHT NOW TODAY -- The US has kicked in some $30Bill into a GLOBAL redistribution scam to the poorer nations run by the UN. All with the premise that Global Warming has ALREADY harmed them. With Obama bucking for MUCH MORE --- that's gonna put a real crimp in the ability to support the needs of OUR debt-filled country to make all the other promises that leftists like for free stuff to the people of this country.
