Re: Gas Prices Would Double Without Ethanol, Ken Field, May 28. Ken Field dispelled three myths surrounding ethanol. I would like to do the same for carbon dioxide.
Myth 1 Man-made CO 2 causes global warming.
Fact 1 Compared to water, CO 2 d
Fact 1 Compared to water, CO 2 does not absorb enough heat energy to be a significant greenhouse gas. There is approximately 40 times more water vapour than CO in the atmosphere.
2 Myth 2 Reducing our carbon footprint will save the Earth from global warming.
Fact 2 Man-made CO 2 is a relatively small amount to the total carbon dioxide in the atmosphere.
Myth 3 CO 2 is a pollutant.
Fact 3 Oxides of nitrogen and sulphur are pollutants. CO 2 is not. It is
a colourless, odourless gas that does not create smog and is essential for life on Earth.
