MIT climate scientist Richard Lindzen slammed this week’s amendment introduced by Vermont socialist Sen. Bernie Sanders that would make it the official position of the Senate that man-made global warming is real and a threat.

Lindzen said Sanders’s amendment to a bill that approves the Keystone XL pipeline an “attempt to hijack science for political purposes.”

“Climate change is of course real; change being the normal state of affairs in climate,” Lindzen told Climate Depot. “Climate change has caused catastrophic problems on occasion throughout the earth’s history. While man may have contributed somewhat to climate change in recent years, his contribution to the above is highly questionable, and continues to be debated.”
