that most cars today put out cleaner air than they take in
 
That is probably limited to PZEV cars and depending what part of So CA you live in. I imagine a diesel truck cleans the air it breaths in San Bernardino... Though we were up there a couple weeks ago and could see the mountains. That was a real treat you rarely see in that smog trap of a city.

Actually the Pollen in Phoenix is a result of major crop growers. It was a very healthy climate until they started planting stuff out there. It is a CO2 sink. That should be worth something.

The Israeli's have also done desert conversion to intense verdant farming. I wonder if they have the same issues? (that we are currently discussing)
 
While I do not think they are related to farming but on my last visit to GC, AZ, I noticed signs that cautioned one against the wild animals as CAN carry Hunta Virus and the plain old PLAGUE vectors. (aka the same plague that wiped out 1/3 of Europe.

but to some elect they're natural "allergens" and they freak out those people's immuno-allergen-response systems so much that they soon have the "elephant on their chest" feeling. It ain't no fun that's for sure. Really scary! Some choice beta-agonist drugs work well in helping alleviate symptoms, and a MDI called Advair works wonders. It works well because it not only reduces inflammation in the bronchial tubes but it also has a 2nd agent in it that opens up the bronchial tubes wider while the inflammation is being reduced (no, I'm not being paid by it's producer to say this). It is an expensive drug, but, if it's properly used, no "rescue" inhaler such as Albuterol needs to be used. It is truly a maintenance drug, this Advair Diskus. And a very effective one.

",,,Hopefully asthma rates will go down too..."
 
Beware those with an agenda, they will get you every time.
 
Let me ask this question. If asthma rates are linked to auto and factory pollution how come they weren't worse back in the 60's when autos and trucks put out 50 times more pollution? Also, where are these factories that the article speaks of? We have killed off any real industry in this country. You can't tell me there are more smokestack industries today than 40 years ago.
 
A few years ago a company was trying to sell ultra-clean diesel engines to all the local school districts. Their sales pitch sounded an awful lot like that article. They even threw in "the children" getting asthma from sitting on the school bus for an hour. Our local leftie newspaper plastered their claims on the front page without checking any of the facts.
 
I wrote to the paper asking one question. If the children are getting asthma from sitting on the bus for one hour, why don't all the bus drivers who spend as much as 15 hours a day on those buses have asthma too?
 
Evidently someone started to use their brain for something other than a paperweight because no one bought those new diesels.

Some of it is probably reporting - lots more epidemiologists are out there now I suspect. But you don't have to go back to the 60's - the rates have been increasing since the 80's up to the late '90s per one study. MedicineNet. But rates appear to be dropping in the US while increasing in Latin America. Sydney Morning Herald.. Pick your study and run with it.
 
In other GW news:
 
"Transportation accounts for almost a third of the country's greenhouse-gas emissions, noted Margo Oge, an auto-emissions expert at the U.S. Environmental Protection Agency. That's a problem of such scope, she said, that even the sweeping legislation aimed at reducing emissions 80 percent by 2050 that failed in the Senate this year wouldn't have made much of a dent."

And, not really related, but you gotta love the street sweeper photo accompanying the story:

I saw this in passing but 40% of all emissions is done by buildings..... So is the ultimate goal "home less ness"?

That is not what the consensus of the scientific UN report said. If memory serves me, it claimed transportation was 15% of all GHG. All the hand wringing over something they know mortal man has no control over is mind boggling. They want more taxes and try every scheme they can think of to stick it to the working man. We will get EVs and plug-in hybrids as soon as the technology is perfected. Raising gas taxes will not rush the technology. It will only hurt the little guy at the bottom of the food chain.

There may be some better worldwide links/stats out there than this one:
 
"In the USA, the rise in transport related emissions is officially projected to be as much as 46% within the next 20 years . In the emerging economies of China and India, the growth in transport related pollution has only just begun."
 
Deutsche Welle
 
Passenger cars account for 17% of U.S. emissions. WSJ

I'm open for an EV. I don't believe the EPA will give approval for a practical EV. They are in bed with the oil companies and will tack on so much crap that we will not be able to afford one. IF Mitsubishi is able to get the i-MIEV approved and to market in the $24,000 range it should be a decent seller, with the Feds $7500 tax credit. That is the only way we can cut emissions, if that is the goal. I think the goal is to keep using fossil fuel and get more taxes from it.
