Not sure why you are getting downvoted. Frank Luntz was the republican PR pollster that advised the Bush administration to replace "global warming" with "climate change" in all White house documents and speeches.

The idea was to make it sound less severe, to please the Oil&Gas lobby. For the most part it worked as you now have environmentalist on the other side of the fence using it too.

I agree with the argument that climate change is maybe not accurate as some regions might cool as well. I would prefer "climate emergency" if I was in charge of the PR.
