Lets see in the last 20000 years the earth has been warmer. Back in the late 70's these same scientists were telling us another ice age was coming. Curbing all vehicle emissions or going zero emissions vehicles in the US will have no effect on global warming( see R&T article from winter issues from 2007) And conserving gas just means we will be playing this game of rising fuel costs and having traders effect the price rather than supply and demand. Using as much gas as quickly as possible will force someone to develop viable alternative forms of energy sonner not later. I don't conserve fuel and see no reason to. We can drill for oil off both coasts and if necessary use the Monroe Doctrine to seize oil fields in Canada, Mexico, Cuba(offshore), and Venezuela. What kind of forum is this Paul? One for followers of the Goracle? Paul do own a gas powered lawn mower? Trimmer? Use it maybe 2 times a month during the Spring, Fall and Summer? Then you are throwing out more pollution than any 02 with a 3% Co does in month of driving. Get over yourself.
