Paul Krugman joins the crowd who think that they can see the signal of greenhouse emissions in noisy, short-term data on food prices, and then construct a chain of causality to the ongoing unrest in the Middle East. Such tenuous claims of attribution have about as much scientific standing as Pat Robertson saying that Hurricane Katrina was the result of the vengeful wrath of God.
Here is what Krugman writes today:
“[T]he evidence does, in fact, suggest that what we’re getting now is a first taste of the disruption, economic and political, that we’ll face in a warming world. And given our failure to act on greenhouse gases, there will be much more, and much worse, to come.”
