Come on. You've seen the charts. You know the science. GW lobby is pretty much every expert who studies the climate, and they're in agreement that the evidence clearly suggests human culpability. As for the second argument, surely it conflicts with the first. If climate change is a good thing, why try and deny human involvement? That's like Neo-Nazis who deny the holocaust, then rant about how the Jews should be wiped out. Not that I'm comparing you to Neo-Nazis. lol
I think climate change will be very disruptive to hundreds of millions of people worldwide. It's easy to sit here in the comfort of the developed world and talk about the opportunity presented by change (I even sometimes have the same impulse). But then one has to think of all of those Bangladeshis whose homes will be flooded and who will have no where to go. We should really be thinking about how to mitigate and manage the disruption.
