This is the nub of my argument - who says we have plenty of time? based on what? based on "simply do not have enough information to predict"? The permafrost specifically is an unknown. We know that it can happen, we know that it will happen if left unchecked, but we don't know if we can stop it, or how much it will take to stop. It's starting to happen already - it's melting and venting now - and it's a positive feedback system. And again, even if I agreed with you about how long we've got, 10-15 years is an eternity in politics and doubly-so if any action is going to come from public pressure. You saw the pressure for and lack of result of Copenhagen, didn't you? The bungling of every other irreversible issue such as managing fish stocks, biodiversity, etc.
