Short Rations: Combined Climate Change and Air Pollution Could Cut Harvests

Food production MIT Newsoffice Graphic Illustration: Christine Daniloff/MIT Interactions between rising temperatures and air pollution could significantly reduce food production around the world, according to an article by Professor Colette Heald, former postdoc Amos Tai, and Maria van Martin (Colorado State University) in the journal Nature Climate Change. While it is known that both higher temperatures and ozone pollution can lower crop yields, “nobody has looked at these together,” said Heald. They investigated global production of rice, wheat, corn and soy, and predicted that damage could be substantial but will vary considerably depending on the crop and the region. Any yield reductions would exacerbate the problems of feeding a growing population with higher dietary expectations. Read the full MIT News Office story:
