Global warming could stifle cleansing summer winds across parts of the northern United States over the next 50 years and worsen air pollution, U.S. researchers said on Saturday.
Further warming of the atmosphere, as is happening now, would block cold fronts bringing cooler, cleaner air from Canada and allow stagnant air and ozone pollution to build up over cities in the Northeast and Midwest, they predicted.
“The air just cooks,” said Loretta Mickley of Harvard University’s Division of Engineering and Applied Sciences. “The pollution accumulates, accumulates, accumulates, until a cold front comes in and the winds sweep it away.”
