Climate change-caused droughts take toll on global crops

Drought and extreme heat slashed global cereal harvests between 1964 and 2007 – and the impact of these weather disasters was greatest in North America, Europe and Australasia, according to a new study published in Nature led by UBC and McGill University researchers.

At a time when global warming is projected to produce more extreme weather, the study provides the most comprehensive look yet at the influence of such events on crop area, yields and production around the world.
