The March Edition of Scientific American is on-line. It includes an article, "Defusing the Global Warming Time Bomb" by James Hansen which looks interesting enought to schedule a trip down to the local library in the next couple of weeks. Especially in the light of the fifth of the twenty theses that Andrew Bolt nailed to the door of the Sydney Institute last Wednesday, viz:

No, man-made global warming is not a proven or "agreed" scientific fact.

Looks like the leftist liars who infest the Australian media have taken over at Scientific American as well. Or at least their American counterparts have.
