After Gore's movie I felt satisfied that I drive an '04 Prius for these last 3 1/2 yrs but everyday I see countless semi's belching out diesil fumes that leave me wondering why "they" get away with such excessive pollution. Also I'm a retired locomotive engineer wondering why so many commercial trucks when a train is 20 times more efficient.

Whether you believe in autos being a major contributor or not, it looks like those 1+ billion people in China are continuing to consume more and more oil and coal for their industry, and their desire to drive. I guess competition for gasoline and price increases will be worse.

The only realistic way to cut GHG is use diesel engines instead of gas. You get 1/3 less CO2 right off the bat.
 
It does not sound like the decision was a slam dunk on anything but giving the EPA the authority to decide on how to handle GHG. Same people at the EPA that have fought against CA making rules that were not in line with the EPA. Ahnold is still asking the EPA to grant authority to CARB. So what was really won with that decision?

"Any new rules about tailpipe emissions are likely to be years away."
 
Supreme Court Decision Sets Stage for Tighter Regulation of Tailpipe Emissions
 
The fight does remind me a bit of the Freon battle; DuPont made a lot of money switching over to other refrigerants. Some say DuPont backed the Montreal Protocol just because their R-12 patent was expiring - in any event the company made money and came out of the battle looking a bit greener. And green is selling right now.
 
The smart automakers (Honda?) will embrace the latest trend too, instead of waiting on the regulators.

I'm not a real Honda fan, but they do keep ahead of the curve on emissions. I think they should have the Green banner way ahead of Toyota.
 
As far as GM and Ford, I think they have already side stepped the GHG issue with offering E85 equipped vehicles. They are touted as practically carbon neutral by some folks. Now it is up to the farmers and ethanol producers to supply this elusive fuel. Buy a Ford or GM truck that is Nature Friendly. Not some gas guzzling Tundra or Titan. Who cares that 99% of those big trucks will never smell E85.

Careful or I'll be plugging stuff on the site all day.
 
"GM has made a commitment to producing E85 FFV’s, with more than 2 million of these vehicles on the road in all 50 states."

The sky is falling. Sound familiar?
 
Now I agree that man has made mistakes and treated this world poorly, but they have found that Mars and Saturn's temps are raising comparably to Earth's and as far as I know, we haven't been to either one yet.
 
35 years ago, they were one a tangent about how the hole in the ozone would cause the polar ice caps to melt in 25 years and raise seal levels and all that. Well, 10 years past that point and there hasn't been much change.
 
A person can argue this subject for a hundred years, cite thousands of articles which contradict each other over and over and we would all end up in the same spot.
 
If you were to look at fossil data showing the temps of the earth during certain period and CO levels during those periods, you would find data that shows that in some instances, the CO levels were 3 times what they are now.
Sadly, man wasn't around during those times.
The earth has gone through some pretty severe climate changes in the past and not one of them were related to man.
 
The bottom line is to take a look at the history of the earth, the data available from those times and the current data and sift through the garbage and draw your own conclusion.
 
The thing that bothers me is the folks who say that people are wrong for believing one thing or another. When you have half the scientist saying one thing and the other half saying the opposite, no wonder things are messed up.
 
Understand that Al Gore is NOT a scientist. He is a politician. And as was once said of politicians, they are like diapers. They should both be changed regularly and for the same reasons.

Well, it not only gave the EPA the right to regulate greenhouse gas emissions, it mandated that they either do so or provide very compelling evidence why they should not.
 
And either way, it basically leaves them without grounds for denying California a waiver to do its own thing, which is all that California was asking of the EPA anyway. Which is why that one should go ahead fairly quickly, hopefully this year (to take effect for the 2009 model year).
 
That then leaves the possibility of an injunction by the court over the lawsuit launched by the automakers, not too likely, and the possibility the automakers will win the lawsuit, which is more likely than an injunction but less likely after today's Supreme Court verdict.

What does CA really think they can do to curb GHG. It is all political BS. The only thing that can possibly happen is for them to further erode an economy that is on the verge of recession. I buy foreclosures. I cannot keep up with the rate of defaults currently going on in San Diego. And we are doing better than most areas of the state.
 
What I see Ahnold and his Hollywood buddies trying to pull off will cripple this state. It will make Gray Davis look competent. That is not easy to do.

Cities and states all around the country are signing on to their own version of Kyoto because the federal government has not led the way on this one. All California is doing is joining that movement and the rest of the countries in the world that have been abiding by Kyoto for some years now.
 
It is easy to forget how much we depend on natural systems for the wealth of resources we find ourselves with. If humanity damages global ecosystems to the point where the fragile balance that exists is gone, it won't matter how much the cost of Kyoto will have been in dollars, for the people just trying to survive. Whether we are the victims or the cause of other peoples' suffering, it won't be a good feeling.
 
We are very very dollar-oriented in the U.S., but there are other things that matter as well. And it's not like California has outlawed the car or something. They have just recognized its crucial role (and no it's not the only contributor) in increasing global warming.
