"With less than two weeks to go until the Opening Ceremonies of the Beijing Winter Olympics, the Chinese government said it is battling “extremely unfavorable” weather to clear the city’s skies of hazardous smog.
On Sunday, Beijing residents’ air pollution apps turned purple, the color indicating a “very unhealthy” level of tiny particulate matter. Forecasts for the next seven days suggest a midweek improvement, then another deterioration ahead of Jan. 31, Lunar New Year’s Eve, when authorities may have to contend with celebratory fireworks releasing plumes of smoke into the sky.
On Monday, the Ministry of Ecology and Environment said the Olympics are arriving just as seasonal weather creates “extremely unfavorable conditions” across northern China. Ministry officials promised to fix the situation ahead of the Opening Ceremonies on Feb. 4 and authorized local governments to take “necessary action” to improve air quality."
