Haze doesn't just block the solar radiation. It is also infamous for acid rain and respiratory diseases.

The haze may have masked the effects of global warming across large parts of China, particularly in the central and eastern regions, where daily high temperatures have actually been decreasing. This may seem like good news, but any success China has in curbing emissions will accelerate the effects of global warming in those areas when the cooling mask is lifted.

It just makes everyone feel sunnier.

Three days later, they're still on cloud nine.
