Irvine, Calif. Future climate change will cause a regionally uneven shifting of the tropical rain belt - a narrow band of heavy precipitation near the equator - according to researchers at the University of California, Irvine and other institutions. This development may threaten food security for billions of people.
In a study published today in
Nature Climate Change, the interdisciplinary team of environmental engineers, Earth system scientists and data science experts stressed that not all parts of the tropics will be affected equally. For instance, the rain belt will move north in parts of the Eastern Hemisphere but will move south in areas in the Western Hemisphere.
