The Us Supreme Court To Hear Case On Global Warming

The U.S. Supreme Court has agreed to hear a case on global warming. It's the second case in 4 years, and this one starts on Tuesday. In one corner, the Obama administration and several power companies, the other, the Environmental Protection Agency. At issue is whether or not the EPA has the authority to make rules about how much greenhouse gases are emitted, supposedly affecting climate change. The president's team argues the decision lies with the federal court, not the EPA. In a 5-4 vote in 2007, the Supreme Cout ruled the EPA had the right to regulate emissions from cars and trucks-- but now, they want to extend that right to power plants, and the cost has some plants frustrated.
