McCain differs with Bush on climate change
PORTLAND, Oregon: Senator John McCain sought to distance himself from President George W. Bush this week as he called for a mandatory limit on greenhouse gas emissions in the United States to combat climate change. McCain, in a speech on Monday at a wind power company, also pledged to work with the European Union to diplomatically engage China and India, two of the world's biggest polluters, if the nations refuse to participate in an international agreement to slow global warming.
