Richard Lindzen, a Professor of Atmospheric Science at Massachusetts Institute of Technology who appeared on the documentary The Great Global Warming Swindle claimed:
Scientists who dissent from the alarmism have seen their funds disappear, their work derided, and themselves labelled as industry stooges… Consequently, lies about climate change gain credence even when they fly in the face of the science.
In that same documentary, Timothy Ball, a Former climatology professor at the University of Winnipeg in Canada, has received five deaths threats by email after expressing his views on GlobalWarming Awareness2007 as shown in the documentary video The Great Global Warming Swindle. In one email mentions if he continued to speak out, he would not live to see further global warming.
I can tolerate being called a skeptic because all scientists should be skeptics, but then they started calling us deniers, with all the connotations of the Holocaust. That is an obscenity. It has got really nasty and personal.
As expressed in the documentary, several scientists claimed the theory of man-made global warming had become a “religion”, forcing alternative explanations to be ignored.
