Rep. Lamar Smith (R-TX) is set to take over as Chair of the House Committee on Science, Space and Technology, and it's causing some dismay on the left, because Smith has questioned the scientific consensus on climate change.
Smith has referred to climate scientists as "global warming alarmists," and in 2009 he accused the mainstream media of "bias" for failure to cover "any dissenting opinions about global warming...The networks should tell Americans the truth, rather than hide the facts." However, Smith's website refers explicitly to the fact that the climate is changing - it just doesn't mention that humans have played a role.
Some science insiders are more pleased than concerned by Smith's appointment. A piece on the American Association for the Advancement of Science website reports that "many Washington-based lobbyists for universities and science organizations privately said that they hoped Smith would win the job. They see him as a pragmatic lawmaker who is most likely to revive the science committee."
