My younger, but not youngest, Brother sent along this item regarding climate change.
From The New Repbulic, we have "Why the Decision to Tackle Climate Change Isn’t as Simple as Al Gore Says", by a Mr Jim Manzi.
It is about the calculation of risk and comparing risk. It is just a lick and a promise, but it does help put the arguments in some sort of relationship.
Longish but interesting.
