To some degree, I believe it is. But then the rain comes along and washes it all back to earth. That's how acid rain is created.Isn't Diesel exhaust too heavy to remain suspended in the air ? Same with coal emmisions who's particulates settle to earth. I would think the great number of jets and their exhaust remains suspended in the upper atmosphere, notwithstanding the vapor trails expelled ? Has to be a enormous smog exhaust slick encircling the earth.
The thing with all these new expensive environmental regulations is that nobody can tell us in plain English what these measures will do for us. In the Cleveland area, we are plagued with E-check. You have to take your car in and have it checked out before you can get license plates. Before they came up with this nonsense, they measured the air quality on the worst possible hot humid day, and stated our air was at dangerous levels. They instituted the E-check, and ten years later, measured the air again, and nothing changed. So what did they do? They decided to continue E-check. And these are the very same people that want to run our healthcare.
Millions of dollars washed right down the drain. Those millions could have been better used by being circulated in this area instead of being sucked down that environmental well that never seems to get filled. The funny thing is that even if you fail E-check, all you have to do is invest a couple hundred dollars towards repairs of the vehicle, and they will let you drive away smoking up the street with anything that shoots out of the exhaust.
I don't worry about energy companies making five or six percent profit. I get something for the money I spend. Not so with environmental costs--many of them hidden away so we can't see them. Last year, Sears came out to repair my snowblower. While the technician was here, I told him that I can't get full power out of the engine because when I totally close off the choke, it loses power and at times even shuts down. He told me that's the way they are made now. You can't close off the choke for full power because it causes too much pollution. Yes, they even attacked our lawnmowers and snowblowers.
