A group with ties to the fossil fuel industry launched a new ad campaign today [1] pushing the idea that carbon dioxide isn't an environmental pollutant. The organization "C02 is Green" funded a half-page advertisement in The Washington Post urging people to call their senators and seek a vote against "the president's cap-and-trade bill that will increase your cost of living and not change the climate. "The bill is based on the false premise that man-made CO2 is a major cause of climate change," the ad says. "Real, empirical evidence indicates it is not."
