Carl Sagan and the Suppression of Uncomfortable Ideas

Seminal astrophysicist Carl Sagan explains why uncomfortable ideas may be banned in religion, they must not be shunned in science.

This is an important concept in American life today, as conspiracy theorists are convinced that climate change denial cannot be considered in scientific circles.

I happened to bring this up in my interview with Dr. V. Ramanathan of the Scripps Institution, who has been amassing data on global warming since the 1970s.  He laughed, and explained, “If I could prove that human activity was not causing temperatures to rise, I’d be be one of the wealthiest and most famous scientists in world history.”
