Watch China Disappear And Reappear Amid Heavy Smog

Images capture the ebb and flow of China's climate crisis.

Beijing's air pollution got so bad this week that officials issued the first ever "red alert" on Monday, closing schools and imposing traffic restrictions because of heavy smog. 

The images below capture the ebb and flow of China's smog crisis and show blue skies overtaken by gray, only to be blown away again to reveal the famous landmarks and buildings beneath. 

These images of the Beijing skyline were taken between Oct. 27 and Nov. 28, 2015 and show just how low visibility can get when smog reaches dangerous levels.
