Those who say climate change is a threat to the planet continue to call for actions against climate skeptics.

On May 19, PBS’ “Moyers & Company” played a clip of scientist, David Suzuki, calling for politicians skeptical of man-made climate change to “be thrown in the slammer.” On day later, a tweet by well-known alarmist Michael Mann suggested that skepticism could be a “crime against humanity.” As least far back as 2006, and as recently as March 2014, liberal journalists and radical scientists have advocated punishing people who doubt catastrophic, man-made climate change.
