On Friday, the City of Regina announced they were cancelling a keynote presentation by climate skeptic Patrick Moore, effectively caving to pressure from climate activists who don’t believe there’s room to question anthropogenic climate change.

The de-platforming of Moore is not a total outlier – environmental writers and researchers who do not parrot the usual climate change talking points have been cancelled a handful of times in the recent past. 

Patrick Moore, a founding member of Greenpeace, has a PhD in Ecology and brands himself a “Sensible Environmentalist.” He denies that climate change is primarily caused by human activity, and maintains that carbon dioxide is not a toxic pollutant, but a “life-giving substance” that should be celebrated.
