The Most Terrifying Video You'll Ever See http://www.youtube.com/watch?v=bDsIFspVzfI
(as the reference I saw said, "the title is a come-on".)

and the follow-up (you can just watch the latter, it is essentially a re-do of the original which has companion videos that explore the issues in much more detail):

How It All Ends: http://www.youtube.com/watch?v=mF_anaVcCXg

I haven't watched the companion videos yet. One potential hole that I can spot with the reasoning--which he may have covered--is that it's possible that we could take decisive action and _still_ get completely screwed by climate change. It's even possible that taking decisive action could cause things to get worse than they would have otherwise. I personally consider these to be low-probability possibilities...but they should be explicitly acknowledged.

The other possibility that's worth mentioning is that taking action can help us to solve other problems than "just" the consequences of climate change (e.g., unfortunate dependencies on unstable countries). Then again, he did say he was simplifying to the worst case.

Anyway, it's worth at least checking out the first link.

I personally don't have very much of an opinion about global warming. If pressed, I will assume that it's happening and if left unchecked that its consequences may be disastrous...but I haven't done anything like the kind of meta-analysis that would be necessary in order for me to have an _informed_ opinion.

(For the record, I assume it's happening at least in part because the consequences of that assumption should lead us, in large part, to take actions that I consider to be a good idea anyway, e.g., slowing our consumption of nonrenewable resources and increased efficiency in a variety of contexts.)

Anyway, these are two essays on somewhat-opposed sides of the debate. Dyson's essay is particularly interesting because he spends a fair bit of it talking about the value of scientific heretics and heresies. He may have fallen a bit in love with being a gadfly, but I think that his basic point is sound. Worth reading, and quite readable.

It's the New Scientist so it's not exactly high-quality science journalism...but it's not bad, and it's reasonably accessible.
