global warming and game theory

You have got to watch this video. It's a simplified explanation of why we have to take action on climate change. The risks of not acting are so much worse than the risks of acting. I've been saying this for a long time: how can we compare the risk of an economic downturn with the risk of global catastrophe and possible extinction? They're not even in the same playing field. As this science teacher says, we have to eliminate the latter as a possibility. It's just too dangerous to play around with.

And if you're thinking about stewardship, it's not just stewardship of the planet we're talking about here: it's stewardship of ourselves, of the whole human race, of every resource we've ever been given. We could lose a little money, or we could lose everything. It's hardly a choice.
