It’s not really a problem that he gave a speech at a Kentucky University on a matter of public concern, and it doesnt matter much who invited him.
The problem would depend on WHAT HE SAID.
So, what did he say anyway?
Here are the undisputed facts:
1. Grayson gave the keynote address at a conference convened to address the grave problem of global warming.
2. Grayson’s speech was billed thusly: “Secretary Grayson will discuss how Kentucky can respond to the challenge of global warming and climate change. Event is sponsored by EKU’s Committee on Responsible Environmental Stewardship as part of the national “Focus the Nation” event.”
Absent the actual speech, everyone has to decide for him/herself how to interpret these facts. Personally, I have never seen a keynote speaker who opposes the premise of the conference he/she is keynoting. Coupled with the description, I reasonably infer that Grayson is a warmist.
To what degree (pardon the pun), I don’t know.
