World's most important crops hit by global warming effects

By Steve Connor, Science Editor
Published: 19 March 2007

 Global warming over the past quarter century has led to a fall in the
yield of some of the most important food crops in the world, according
to one of the first scientific studies of how climate change has
affected cereal crops.

 Rising temperatures between 1981 and 2002 caused aloss in production
of wheat, corn and barley that amounted in effect to some 40 million
tons a year - equivalent to annual losses of some £2.6bn.

The paper in question is Global scale climate–crop yield relationships
and the impacts of recent warming by David B Lobell and Christopher B
Field and can be read online:
