Is There a Non Zero Chance That Global Warming Will Spin Out of Control?

There's two ways you can think about cost benefit analises showing that climate impacts are th doing. One is to say there might be a tiny risk, but it's not greater than zero. And then the argument would be, well, if there's one % chance of an infinite epocalypse, it's worth any donation of resources to stave it off. I surly think you can make your argument even stronger by saying poverty breeds terrorism and willingness to yo do a lot of bad things.
