Smithsonian Accused of Altering Exhibit

A graphic on a Smithsonian website is displayed in an internet browser April 27, 2007. A Smithsonian exhibit on climate change in the Arctic included a subtle change to one graphic, the "Climate Rollercoaster." The graphic shows fluctuations in the Arctic climate over the past 20,000 years. But at the end of the "rollercoaster," three small arrows (top right of graphic) were added to indicate that it is unclear how much the Arctic will continue to warm, according to exhibit curators. One former administrator says the Smithsonian was self-censoring the exhibit to avoid any political conflicts with Congress or the Bush administration. (AP Photo/The Smithsonian)

(AP) -- The Smithsonian Institution toned down an exhibit on climate change in the Arctic for fear of angering Congress and the Bush administration, says a former administrator at the museum.
