Ranking minority member of the Senate Environment and Public Works Committee, Sen. Inhofe is one of the most outspoken skeptics in Congress. In speeches on the Senate floor, he has called the threat of what he characterizes as "catastrophic climate change" the "greatest hoax ever perpetrated on the American people." He has challenged the existence of a scientific consensus and attacked scientists whose research is prominently cited in the IPCC reports, and in 2006 directed his ire at Al Gore's "An Inconvenient Truth" and accused news media of hyping "alarmism." Much of his material is written by his communications director, Marc Morano, former staff writer for conservative CNSNews, and former reporter and producer for Rush Limbaugh's television show as well as the syndicated TV newsmagazine "American Investigator." Sourcewatch, a project of the Center for Media and Democracy, says CNS and Morano were the first source in May 2004 of the Swift Boat Veterans for Truth  claims against John Kerry  in the 2004 presidential election  and in January 2006 of similar attacks against Vietnam war veteran John Murtha.  Morano squared off with reporters and NASA Goddard's James Hansen at SEJ's 2006 conference,  and he publishes a blog on the Senate E&PW Committee website. Phone: 202-224-6176.
