Re: [APML] Dark Sky article

Tony,

There's no doubt some of the occasional sky degradation is coming from
dust in China. The milky white skies (at least out here) are often
caused by upper level lows that lift moisture and particulates high
up. We had one of these just last week and we may have a repeat for
the next few days. Without the lifting action of the lows, that suff
quickly settles in the valleys and leaves the higher elevtions clear.

Dale,
 
   It gets worse...
 
   I just read an article yesterday about all the air pollution coming
across the Pacific from China... air pollution and dust. They burn mostly
coal over there, the soil is being turned into "desert-like" terrain by
excessive clearing of land, they produce 40,000,000 TONS of sulfur dioxide a
year and other numerous pollutants on a scale that is hard to imagine... and
it all blows over here, especially in the Spring.
     I live in a fairly pristine area but I have always wondered why the sky
sometimes has this high altitude scrim to it... sometimes white, sometimes a
pale yellow... now I know what it is.
    Since almost everything in the world is now being made in China, I have
decided that all I can do as an individual is stop buying anything that is
made there... at least until they cut back on their pollution, which is not
going to happen any time soon.
