ENVIRONMENT -- BOEHNER CITES COW FARTS IN ORDER TO DOWNPLAY GLOBAL WARMING: Yesterday on ABC's This Week, host George Stephanopoulos asked House Minority Leader John Boehner (R-OH) to describe the GOP "plan" for dealing with global warming. Boehner downplayed the risk of carbon dioxide and global warming, claiming carbon dioxide is simply a natural compound that is present even in cow flatulence. "George, the idea that carbon dioxide is a carcinogen that is harmful to our environment is almost comical. Every time we exhale, we exhale carbon dioxide. Every cow in the world, you know, when they do what they do, you've got more carbon dioxide," he said. While humans and animals exhale carbon dioxide naturally, no one is arguing that CO2 itself is harmful. But excessive carbon dioxide in the air is harming the planet and human health. In fact, the Environmental Protection Agency recently ruled in a landmark decision that carbon dioxide emissions are "a danger to human health and welfare." Furthermore, it is methane, not carbon dioxide, that is the primary chemical in cow flatulence that contributes to global warming. Boehner also expressed skepticism about the degree that global warming is caused by man. "The question is how much does man have to do with it, and what is the proper way to deal with this?" he asked. Boehner isn't the only Republican to downplay the risk of greenhouse emissions recently. Rep. John Shimkus (R-IL) said last month that capping carbon dioxide would take away "plant food" from the atmosphere.
