An international team of researchers has quantified the biggest problems with Earth’s food. In a nutshell, it’s getting harder to grow enough to feed everyone.
Droughts, heat waves and floods likely brought on by climate change are getting more frequent, as is their suppressive effect on the global food supply.
Researchers with the U.K. Global Food Security program found food shortages caused by extreme weather will be three times more likely over the next few decades.
The researchers stress their numbers are predictions based on limited data but nonetheless suggest “the risk of a 1-in-100 year production shock is likely to increase to 1-in-30 or more by 2040.”
Their models suggest by 2070, such shocks could be happening in seven out of every 10 years. The changing climate is one of three major stress points on food reserves.
