Pat Sajak: “global warming alarmists are unpatriotic racists”

Here’s one puzzle from Wheel of Fortune’s Pat Sajak I doubt anyone can solve: Why in the world he said this:

I now believe global warming alarmists are unpatriotic racists knowingly misleading for their own ends. Good night.

Sajak voices strongly held views about weather and climate on Twitter frequently, reports Huffington Post Green

Very hot weather: ″We’re all going to die!” Very cold weather: ″There’s a difference between climate & weather, moron!”

He obviously missed my post calling for more constructive climate change discussions:

But a plea: let’s debate this issue constructively and avoid name-calling.

Deep-six the term “denier” and abandon “alarmist”. Let’s get “warmist” out of the way, too.
