A new study from Stanford University suggests that the kind of hot, dry conditions that can shrink crop yields, destabilize food prices and lay the groundwork for devastating wildfires are increasingly striking multiple regions simultaneously as a result of a warming climate.
According to the researchers, climate change has doubled the odds that a region will suffer a year that is both warm and dry compared to the average for that place during the middle of the 20th century. It's also becoming more likely that dry and severely warm conditions will hit key agricultural regions in the same year, potentially making it harder for surpluses in one location to make up for low yields in another.
