Global Warming - Eliminating all U.S. gasoline powered vehicles would reduce...

What were the temperatures before 1880? You're telling us a 120 year snapshot of a planet thats been around for a few billion years is a good way of judging changes?
Use of a misleading graph post-industrialisation is poor form.

And speaking of climate change...
So the world temperature has gone up one point two degrees centigrade on average in the last 120 years?

.8.
And the % rise is completely irrelevant if you don't know how much of an % is dangerous.
If a 1% increase is catastrophic, it suddenly makes a big difference

The meat industry is the number one environmental pollutant upon this world, which includes it also being the number 1 destructor of the Amazon rain forest, the keeping of Live stock on a mass scale (CO2), the transportation of meat goods and live stock etc, add all of these up and you have the number one polluter and cause of global warming.
This debate isn't going to end well.

Oh and that graph is a terrible thing to use for any global warming debate 
It's over SUCH a short time scale, it shows nothing:
And no, I'm not an anti global warming theorist, I'm an Environmental Sciences student so just like to get it right

From Wikipedia
(Just as a note, something to watch with carbon emissions is whether they're talking tonnes of carbon, or tonnes of CO2)

Not exaclt about car emissions, but it does make the OP's 0.18% seem pretty low when you look at this... Wiki CO2 Emissions

No, I didn't say that. My actual words were "And speaking of climate change..." That's all I said.
What's misleading about it?

I think this is an interesting graph, it shows the temperatures (Blue) over the last 650,000 years and also the CO2 concentration (Red) along the same time scale,
You see how they match up, you'll also see that recently the concentration of CO2 has risen immeasurably, now I'm no scientist but the way I see it the would runs on a balance, and atm we are messing that balance up, now how this increased CO2 concentration is going to effect temperatures only time will tell but I can't see it having no ill effect at all, I realise that the worlds temperature rises and falls naturally, you can see that for yourselves, but for the first time ever we are riding an arc that is accompanied by an extra large rise in CO2 caused by us, a modern industrialised world that didn't exist during the last temperature peak/s.

Some great posts by mr jack and lowrider on the GW subject...
Global Warming as far as we see in the news,etc. is a myth... mostly for political ends... but like many things theres a kernel of truth beneath it... if we do leave our CO2 and so on emissions unchecked then eventually we are going to have to face some issues due to it.

I guess my issue is taxes are being raised in effect to try and force us out of our cars. If the figure I quoted in the OP is correct the outcome of this will be sooooo small you have to wonder how justified is it?
Yes, we all want a cleaner planet with electric cars charged via solar or fusion, but my question still stands.

The figure is true but misleading for the reason I explained in my last post. And, in any case, if you look at any particular contribution to the problem it won't be large enough to make a difference; what is needed is a large number of small contributions.

I don't know about overall pollution, but China is certainly the world's largest CO2 polluter.
And speaking of climate change...
Dont you just love how this graph gets rolled out. It quite convieniently starts at 1880 because the temperature before then was higher, so to show it from then makes out it wasnt so hot before the industrial revolution. Thats why it is misleading.

Id just like them to have to pay what we do for their fuel. Cars that do less than 10 mpg would bankrupt the average working class man over here yet they seem to be quite viable over there.

Goes to show, global warming or climate change is a bunch of crap.

It's a convincing graph but doesn't on it's own support the view that rising CO2 increases world temperatures.
It is just as plausible that rising world temperature caused elevated CO2 (due to rotting matter and increased animal and plant growth).
I'd be more concerned about acidification of the oceans personally, that's assuming there isn't a buffer effect and assuming ocean life cannot adapt.
Ignoring any environmental effect, oil should be kept for it's many other uses (building materials, plastics, fertilizer and animal feed).
Nuclear fission can provide all the energy the world is ever going to need, if it had started out as a power source instead of a bomb we'd have reactors in our cars by now (or trucks/ trains at least).
