Report: Food crops unable to adapt to pace of climate change

Global warming could rapidly threaten grasses including staple foods such as wheat and rice that provide half of all the calories consumed by humans, say scientists.

A study looking ahead to 2070 found that climate change was occurring thousands of times faster than the ability of grasses to adapt.

While the research cannot predict what might happen to world food supplies as a result, the authors warn of “troubling implications”.
