Dirty Birds



“The soot on these birds’ feathers allowed us to trace the amount of black carbon in the air over time, and we found that the air at the turn of the century was even more polluted than scientists previously thought,” says Shane DuBay, a graduate student at The Field Museum and the University of Chicago and one of the authors of the study. He and co-author Carl Fuldner, also a graduate student at UChicago, analyzed over a thousand birds collected over the last 135 years to determine and quantify the effects of soot in the air over cities in the Rust Belt.

I love real science.

Youngens have no idea how bad pollution was. So Cal has improved a lot but piling more people in doesn't help.

Interesting article on ZH toady about accidentally finding enriched uranium in the air over Alaska.

When I was a kid lookin in Birmingham in '63, there were 260 days a year that the air was dangerous to breathe. We lived there a year while my Dad finished college, and I don't remember seeing the sun that entire year. I was quite young...

I spent the 6th grade in Balwin Park in the late 1940's. I can remember walking home from the movies and watching fingers of soot floating down like snow. At that time there were a lot of citrus groves in the area and the farmers would burn discarded crankcase oil in what were called smudge pots. At home, I could look in the bath mirror and see black rings around each nostril. Good Times!!!
Cinco-x up remembered not seeing the sun that year. I went to Detroit in 1960 to witness a cold weather test. I met our company rep for diner and he talked about being depressed in Detroit and didn't know why until the sun came out in the spring.

The worst place I ever lived was Upland and the air was horrid. Kaiser steel plant in Fontana polluted the air and it would back up to the hills. Lived there six months and had a sinus infection till we moved to Santa Monica.

I remember the smug pots as well back in the days of the orange groves. Simple life back then.

I lived in Western Pennsylvania when I was a kid in the 1940's and early 50's. I remember the night sky was lit up red due to the blast furnaces at the steel mils around Pittsburgh. Quite a bit of pollution going into the air I imagine.

As far as soot is concerned, at one time in the mid 40's, we lived about 100 yards from the railroad track. When a train came along (steam locomotives), my mom would have to run out and take down any wash that was drying on the clothes lines before the soot landed. People had to put up with a lot more back then. We live in the lap of luxury for the most part these days.

In Balto, the air was bad, but not that bad.

Lawyerliz said...

There were some tracks, a few blocks away and I loved to hear the trains rumbling by.

Lawyerliz said...

Soot, as you know, is not carbon dioxide.

Cinco-X said...

Ya... Not a huge fan of regulation, but I do like clean air and clean water

I used to hate visiting Panama City. The St John's paper mill let a horrid stench drift across half the city. Even when the wind was blowing it away, the trees and buildings still stuck

Cinco-X said...

Faaaaak you're old!!!!!!!!!

EngineerJim said...

Ever visit Cedar Rapids Iowa -- city of five smells ?
Quaker Oats and a slaughter house were a couple of them. Not sure what the others were.

Lawyerliz said...

Nope. Why would oats smell? Why would anybody visit Cedar Rapids?

EngineerJim said...

>Why would anybody visit Cedar Rapids?

Rockwell Collins.

Lawyerliz said...

They smell?

EngineerJim said...

Actually the factory does have a distinct smell.
Not unpleasant though.

Lawyerliz said...

It smells of flowers and sometimes of fireplaces here.

Lawyerliz said...

The smell of paper factories has got to be the worst smell in the world. Worse than. Cat Pee and armpits.

Lawyerliz said...

If you get close to the ocean, it smells like ocean.

Lawyerliz said...

A clean cat smells devine.

LBD said...

We got that new dog smell! Chihuahua mix, we think hair color is brown and black like a dachshund. Maybe the Vet can tell as the shelter wasn't sure of much. They think she is 5 years old. Cute and happy to be home. Our little dog Suzie is now the big dog. LOL!

Any guesses as to what she is?

Lawyerliz said...

A dog!

LBD said...

Amazing! LOL!

Goldman is saying that fiscal matters were entering uncharted territory. People said that a lot on calculated risk and I agreed. A lot of people got kicked out of their houses, quickly rather than slowly. Nothing particularly uncharted happened.

LBD said...

Good Morning!

Here we go again! giving money to people marginally able to pay it back, to cheaply has a track record. I wish it would hit 6-7% and houses start to be affordable.

My last rental is under contract at a small reduction in rent. Empty for 5 months. Recession in full swing.

Lawyerliz said...

Where are you, I forget. I don't see it, anywhere in Florida.

Lawyerliz said...

Of course we are getting all that space related business.

LBD said...

Central Nebraska, out side North Platte a rail road town with truck stops and a great hospital. Part of the problem is low wage earners can go to Calirado and get a higher minimum wages and smoke pot with out being arrested. For being a large Nebraska city (22K) it never grows and the middle class has been leaving. Weekly wages are about $250 less the Omaha and $400 less then national. IMO

Lawyerliz said...

Wow. Your rentals are there?

Here is the Goldman quote that enraged me:
“ In the past, as the economy strengthens and the debt burden increases, Congress has responded by raising taxes and cutting spending. ”.

Where were they $7 trillion dollars ago? That’s when thevtecivery supposedly began.

Lawyerliz said...

Keysian repose during a recovery is to save some money to have it on the next recession. This is why it's wrong. Politicians can't bear to do that and never will.

Lawyerliz said...

Response dyac.

Lawyerliz said...

What they should probably do is nothing. The best we can expect from politicians as to finance.

Lawyerliz said...

Most people can't do that. Most people can't save a dollar a week.

LBD said...

Yes North Platte. Small towns are pretty much section 8 welfare queens.

Most people are educated into illiteracy. Remember your safety net is your home equity. Oppp's we took it out for a vacation!. There's your savings.

Rob Dawg said...

Keynesian Repose has a certain poetry to it. Nevertheless there is a new post.

Lawyerliz said...

I include the govt in the can't save column. Some times a state govt manages to
