Pollution in China
The Chinese government warns residents in Northern China to prepare for a wave of choking smog arriving over the weekend and lasting through Tuesday, with Beijing affected hardest. The capital city issues its second-ever "red alert" -- the first was announced on December 7, 2015. This alert triggers the odd-even license plate system to halve cars on the road, and recommends schools close. China's National Meteorological Center reports the pollution will stretch from Xi'an, across part of Central China, through Beijing and up into Shenyang and Harbin in China's frigid northeast.
