don’t let the grass grow under your feet!

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

A new study looking ahead to 2070 found that climate change was occurring thousands of times faster than the ability of wild grasses to adapt. While the research cannot predict what might happen to world food supplies as a result, the authors warn of “troubling implications”.

“We show that past rates of climatic niche change in grasses are much slower than rates of future projected climate change, suggesting that extinctions might occur in many species and/or local populations,” wrote the researchers, led by John Wiens, from the University of Arizona in the US.

“This has several troubling implications, for both global biodiversity and human welfare.”
