Extreme weather fuels food price rise, study finds

A new study by the Barcelona Supercomputing Center in Spain has pointed an accusing finger — for short-term food price rises around the world and the subsequent impact on inflation — at climate change, with the warning that this could fuel health problems and even social unrest.

The research has been published ahead of the United Nations' Food Systems Summit Stocktake next weekend, when world leaders will gather in Ethiopia to discuss threats to global food supply.

It looks at dozens of examples of climate impact globally, many of those affecting dietary staples. Previous studies had looked at the longer-term impact, but this latest one focuses on immediate effects.
