Climate change denial reminds me of Lysenkoism. The facts must serve the ideology, and if they don't then it is the facts that are in error. The obvious solution, then, is to ban talking about the facts.
On the one hand it worked. The Senate, this year, happily passed a resolution that "climate change is real and not a hoax", but of course Republican reps gleefully pointed out that, of course the climate changes, no one is disputing that...
But now that "Climate Change" is, to the public, basically just "Global Warming", Florida is now working to ban the very term their political wing invented.
The schadenfreude is strong in this one.
I doubt the American right wing influenced Mr Charney in his naming conventions.

The use of the term "climate change" as part of the public discourse (as opposed to scientific discourse) is as a result of a right wing PR campaign in the 1980s.
