North American crops highly affected by climate change

na-cropsGlobal food production is increasingly likely to be disrupted by extreme weather driven by climate change, say researchers behind a new analysis published on Wednesday in the journal Nature. And, paradoxically, the impact could be greatest in places where farming practices are the most technically advanced, including Canada.

The study is the first to quantify the relationship between weather-related disasters and crop yields in different parts of the globe.

The study’s authors say their work throws a spotlight on the growing vulnerability of the world’s food supply to climate change. Their results could help guide agricultural policies as the atmosphere shifts to a more volatile state because of climate change, even as population growth puts more demands on the planet’s capacity to generate food.
