Here in the United States, the Washington Post is reporting government scientists who specialize in climate research are complaining the Bush administration has imposed difficulties on allowing them to speak publicly on global warming. Researchers at the National Oceanic and Atmospheric Administration said administration officials have berated them for speaking on policy questions; removed references to global warming from their works; investigated news leaks; and sometimes urged them to stop speaking to the media altogether. In one case of White House censorship, several key words were removed from a press release, including “global warming,” “warming climate” and “climate change.” Earlier this year, the top climate scientist at NASA accused the Bush administration of trying to stop him from speaking out about the links between greenhouse gases and global warming.
