What actually happened there is a funny story. Scientists had been using both “global warming” and “climate change” since the 1970s, and a Republican strategist proposed changing the language from “global warming” to “climate change” because he thought they could get an advantage from that. He was rightly ridiculed for this, so the Republicans spent the next decade pretending that Democrats had changed their language in order to scare people.
