I think this is why we want to reduce emissions. As I have said, if we threw garbage on our front lawns all our lives, eventually the yard gets full.
This is not just Beijing, we saw the same kind of thing in Cairo, Bangkok, Mumbai. and even back in the 80's in LA.
I remember we worked in the center of two mountain ranges
east of LA back in the late 80's, my friend had been out there 3 years.
One day the Santa Ana winds came through and it was the first time he said he could see both mountain ranges.
One was 5 miles away, the other 7. Really drove the issue home for me.
