"When House Speaker John Boehner told a group of reporters on Thursday that he would not discuss climate change on the grounds that he, himself, was not a scientist, he joined the ranks of other prominent Republican politicians who have refused to talk about the issue on the same grounds.
“I’m not a scientist,” said Florida Governor Rick Scott last week, when asked if he thought man-made climate change was affecting the weather. “I’m not a scientist,” said Sen. Marco Rubio (R-FL) in 2009, his first in a long line of statement denying climate change. “I’m not sure, I’m not a scientist,” said Rep. Michael Grimm (R-NY) said of climate change in 2010 (Grimm changed his mind on the issue this past April).

But actual climate scientists say the tactic is irresponsible, dangerous, and ignores the fact that credible scientific information is readily available. "
