john doug, why can't you just accept that humans are contributing to climate change? Do you really think that emitting hundreds of millions of tons of CO2 and other greenhouse gases on an annual basis wouldn't effect the Earth?
I don't necessarily discount that CO2 emissions do in some way affect the well being of the atmosphere, I just don't subscribe to the dire warnings of coming disasters, and in turn, the money grab of the federal and state governments. There are much larger variables in play that are conveniently ignored.
If governments around the world were serious about getting us off oil and other fossil fuels, they would put up a prize in the form of a world wide patent and royalties for the first true renewable fuel that is economically feasible to power vehicles and power plants. They would also give tax credits to those companies and individuals for any money spent during proven research and development until the winner is chosen. We just might get a car that runs on salt water.
