In the new research published in Nature Communications, researchers in the United States and Germany looked at the likelihood that several major food-producing regions could simultaneously suffer low yields
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.

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 climate change poses to our food systems.
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.
In the new research published in Nature Communications, researchers in the United States and Germany looked at the likelihood that several major food producing regions could simultaneously suffer low yields.
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.
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.
