i don't think there's any shortage of people willing to debate global warming, so i have to wonder how hard jp has tried to interview them. if you listen to jim and john, they cherrypick any scientific evidence they can find, and as far as they are concerned, the case is already closed. it doesn't matter to them that the northwest passage is open. if the arctic polar cap keeps melting, it will become much more efficient for shipping from europe to asia, as the northwest passage will be a much shorter route than the panama canal. but you can bet jp won't ever mention that.

for all the good information that jp provides, whenever he strays from economics and finance into science or politics, he sees what he wants to see. it's his show, and he can say what he wants, but he has a number of blind spots where he often gets things wrong.
