Why Bad Air in Philadelphia and Denver Today..Climate Change...

[Stuart G]

I looked at this site:
Click on it..it is ok...U.S Government site with info provided by state pollution agencies..

http://www.airnow.gov/index.cfm?action=airnow.main

And clicked on Current Air Quality Index.{Current AQI ]
Now. 7am .....in Philadelphia PA...air is bad..

also..today in Denver it is predicted that the air will be kinda bad..
New Brunswick N.J. bad air....but then. I clicked on the weather in those places..
...not the air pollution ..This morning in Philadelphia Pa...7am

no wind....0 wind

Denver..no wind.. 0 wind..

what does it mean in simple terms.. the pollution from l yesterday has not had a chance to blow away.
so..it piles up and stays put, that is called an "air inversion" .. you can see it at that first map predicting pollution in Denver..
kinda a large circle almost like a ball....brown color..so no wind, equals air inversion...bad air. the Jetstream has been altered...
why?..well... I am saying climate change altered the jet stream. . providing us strange weather.. no wind....often extreme..
fast changing weather..in extremes..that is climate change...more and more of it. no wind at all..more inversions, more pollution
and more people having trouble breathing which is what this is about... humans, breathing dirty air.

1. I don't think this new for Denver

Back in 1964 I lived south of there and the smog was bad. There were newspaper pictures of Denver that resembled LA on a bad day.

I moved away and now 49 years later make trips back. It doesn't seem to me to be as bad and I wondered what changed.

At least you can see the front range now. Maybe I just hit it on good days.

3. Sometimes...it can be something else too...in addition to the wind...

If the humidity is lower, it isn't as bad as if it is high. So there are a number of factors that affect breathing. Even the construction of the building may retain humidity. Yesterday I was in a building with a lot of exposed wood construction. Very beautiful but I could feel the humidity inside of me. When I got up the stairs and went into an air conditioned room, I felt much better even though the wood was still everywhere in the building.
