Beijing smog time lapse

posted by Jason Kottke   Jan 05, 2017

Covering an actual time of 20 minutes, you can watch this time lapse of smog rolling into Beijing in a matter of a few seconds. The NY Times has a short piece on the video, which was filmed on January 2.

Residents have come to expect such dense air pollution in the late fall and winter, as people burn coal to heat their homes. Recently, the problem has been particularly bad, and the city has been enveloped in smog for extended periods starting in October.

Mr. Pope, writing on Twitter, pegged the air quality index, a measure of the pollution, above 400 around the time of the video. The United States government rates readings of 301 to 500 as “hazardous.”

What a disaster…and the air wasn’t that clear before the smog rolled in. I’ve been to Beijing once, back in 1995, and even though I’d love to see how the city has changed over the past 20 years, I have no interest in returning until they get their air quality under control.

Update: And it’s not just Beijing; cities around the world are struggling with pollution. Parts of London have blown through their annual 2017 emissions limits in just 5 days.

By law, hourly levels of toxic nitrogen dioxide must not be more than 200 micrograms per cubic metre (µg/m3) more than 18 times in a whole year, but late on Thursday this limit was broken on Brixton Road in Lambeth.

Many other sites across the capital will go on to break the annual limit and Putney High Street exceeded the hourly limit over 1,200 times in 2016. Oxford Street, Kings Road in Chelsea and the Strand are other known pollution hotspots.
