Record air pollution in Beijing 30 times safety limits.

Guardian: “The Beijing Municipal Environmental Monitoring Centre said levels of PM2.5, tiny particulate matter, had reached more than 600 micrograms per square metre in many areas, and Reuters said it may even have hit 900 – its worst-ever reading.” “The World Health Organisation considers a safe daily level to be 25. ….Breakneck economic growth, reliance on coal, dramatic expansion of car ownership and the widespread flouting of environmental laws have all contributed to China‘s air pollution problems. But the intensity of the current problem appears to be weather-related. The monitoring centre said the heavy pollution had been trapped by an area of low pressure and warned that the problem was likely to continue until Tuesday.”
JL: I stood in that square in 1984 and all I could hear was bicycle bells. How quickly we humans fog things up.
