Paul Krugman on the global food crisis:
World food prices hit a record in January, driven by huge increases in the prices of wheat, corn, sugar and oils. These soaring prices have had only a modest effect on U.S. inflation, which is still low by historical standards, but they’re having a brutal impact on the world’s poor, who spend much if not most of their income on basic foodstuffs. …
While several factors have contributed to soaring food prices, what really stands out is the extent to which severe weather events have disrupted agricultural production. And these severe weather events are exactly the kind of thing we’d expect to see as rising concentrations of greenhouse gases change our climate — which means that the current food price surge may be just the beginning.
We shall be winnow’d with so rough a wind
That even our corn shall seem as light as chaff
And good from bad find no partition.
–Henry IV, part 2
