The hazardous air underscores the challenge facing the government
as it battles pollution caused by the coal-burning power industry
and will raise questions about its ability to clean up its economy
at the talks in Paris.

COP21 Paris climate talks: Beijing and New Delhi choke on smog
China has ordered thousands of factories to shut as it grapples
with swathes of choking smog that were nearly 24 times safe levels
on Tuesday, casting a shadow over the country's participation in
Paris climate talks.
The heavy smog erased the capital's skylines with a monotonous gray
and left buildings just a block or two away hardly discernable.
Neon signs barely punctured the gloom, and many Beijingers wore
masks of various kinds while walking the streets.
The pollution spike is a reminder of China's severe environmental
challenges as President Xi Jinping joins other world leaders at the
Paris climate conference.
If there's a silver lining to the thick layer of smog, it has given
birth to a host of creative gimmicks, from a bicycle with a filters
to canned fresh air.
