Bush's Science Advisor, Senator Clash Over Computer Models: "Representative Henry Waxman accused the administration of invoking scientific uncertainty to discredit evidence counter to its policies.

John Marburger, science advisor to the president, responded that the computer models used to make predictions about climate change and public health were both ambiguous and prone to group-think errors by scientists.

The clash came during addresses to science journalists in a meeting preceding a large scientific conference sponsored by the Association for the Advancement of Science in Washington, D.C."
