I guess the point is 1) Snowguy (and his ilk, like his useful idiot Torie) don't know what they are talking about when it comes to climate change, and they are as wrong and clueless as Palin was about, well - most everything, and 2) if we don't embrace the Green Revolution right this instant, and throw trillions at it, we are all going to die, or suffer grievously..
I know this is an old thread and you are being polemical here, but the idea that doing something about climate change is going to be extremely costly is plain wrong. Seen in a long term perspective the costs will be relatively limited. Not doing anything will be far more costly.
The changes related to creating a sustainable economy will create business opportunities in new industries (and is already doing so) and avoid economic loss related to loss of agricultural land, flooding, desert spread etc. in the future. Its economically prudent and vital for long term growth to do something about climate change.
The whole "this is just doomsday preaching" line is tiresome.
Climate change will increase the over all conflict level in the world and make living conditions worse for large parts of the world, but we are obviously not all going to die
. This demonising of concern for climate change as alarmist and Armageddon prophecies is plain wrong. We are talking about a rational estimation of a problem and its potentially very serious consequences, not doomsday preaching.
