Scare Tactics

(Fox News) - Former Astronaut Harrison Schmitt says scientists are being intimidated into not speaking out against man-made global warming theories.

"They've seen too many of their colleagues lose grant funding when they haven't gone along with the so-called political consensus that we're in a human-caused global warming."

Schmitt recently resigned from a non-profit space exploration organization known as the Planetary Society after the group blamed global warming on human activity. In his resignation letter he said the "global warming scare is being used as a political tool to increase government control over American lives, incomes and decision making."
