Timelapse video shot from a Beijing bank on Monday shows a thick cloud of yellow smog swallowing buildings as it rolls into the city. The footage was taken by Chas Pope, a British engineering consultant, and was shot over just 20 minutes. Many cities in China have been placed on ‘red alert’ due to soaring air pollution levels in the first days of 2017. Clouds of smog have forced flights to be cancelled and roads to be closed and have effectively left some people trapped in their homes. Pope told the Guardian that smog was one of the main drawbacks of life in Beijing. “It gets you down especially in recent winters when it seems to have been getting worse,” he said.
