Climate models had until recently not been performing very well predicting variation in the spring rainfall over northeast China, home to some of the country’s main cereal production. This uncertainty potentially puts the food security of the country—and even the world—at risk. Researchers have however now identified the problem: a previously unidentified major shift that occurred in the mid-1980s in atmospheric flows from the North Atlantic as a result of a weakening jet stream.
