...and what if the modelling on climate proves to be too conservative?
Because that's how it's panning out right now. We're in a feedback loop and the only thing I agree with you on is that it's very difficult indeed to control long term climate trends.
If what I'm saying is true (and obviously I think it is), we're in a lot more difficulty than you can imagine.
The problem is ignorance. Yes, it is. You cannot have an uninformed debate because that's just a competition in shouting.
The oversimplifications on this issue are astonishing. Try to at least understand what the oceanographers are saying about the irreversibility of the change so far, particularly in relation to the melting of the polar caps. And I'm not speaking about surface ice, I'm talking about deep ice which is melting because of the warmer ocean currents.
The claim that climate has always changed misses a key point: that the speed and the rate of change is unprecedented. Other change happened much more slowly, centuries more slowly in fact. The issue is whether this threatens human life. Here we're on a vastly speeded up scenario and we've been gambling with our futures. The planet will survive, no problem there.
