The City of Regina has cancelled its invitation for climate skeptic and Greenpeace co-founder Patrick Moore to deliver a keynote speech at an upcoming conference.

The city caved to pressure from climate activists and academics who don’t believe there’s room to question man-made climate change.

“Keynote speaker Patrick Moore no longer on the Reimagine Conference agenda. This decision aims to refocus discussion back to the gathering’s true intent – to foster meaningful dialogue on how to make the City’s facilities/operations 100% renewable by 2050,” announced the official City of Regina Twitter account.
