The risks of harvest failures in multiple global breadbaskets have been underestimated, according to a study Tuesday that researchers said should be a “wake up call” about the threat\u00a0climate change<\/a>\u00a0poses to our food systems.<\/p>\n

Food production is both a key source of planet-warming emissions and highly exposed to the effects of climate change, with climate and crop models used to figure out just what the impacts could be as the world warms.<\/p>\n

In the new research published in\u00a0Nature Communications<\/em><\/a>, researchers in the United States and Germany looked at the likelihood that several major food producing regions could simultaneously suffer low yields.<\/p>\n

These events can lead to price spikes, food insecurity and even civil unrest, said lead author Kai Kornhuber, a researcher at Columbia University and the German Council on Foreign Relations.<\/p>\n

By “increasing the concentration of greenhouse gases, we are entering this uncharted water where we are struggling to really have an accurate idea of what type of extremes we’re going to face,” he told AFP.<\/p>\n

“We show that these types of concurring events are really largely underestimated.”<\/p>\n

The study looked at observational and climate model data between 1960 and 2014, and then at projections for 2045 to 2099.<\/p>\n

Researchers first looked at the impact of the jet stream \u2013 the air currents that drive weather patterns in many of the world’s most important crop producing regions.<\/p>\n

They found that a “strong meandering” of the jet stream, flowing in big wave shapes, has particularly significant impacts on key agricultural regions in North America, Eastern Europe and East Asia, with a reduction in harvests of up to seven percent.<\/p>\n

The researchers also found that this had been linked to simultaneous crop failures in the past.<\/p>\n
