Climate change will hit food security, study finds

Extreme temperatures during crop-growing seasons will become the norm by the end of the century and will devastate yields and food security, say US scientists. But choice of crop varieties could mitigate temperature rises, a UK study has found.

Europe’s exceptionally hot summer of 2003 is likely to be the norm by the end of the century, according to new climate research.1 Current extreme temperatures are likely to be exceeded in most years across Asia, Africa, the Middle East and Central America.
