As scientific terms go, "climate change" is lame.
It sounds like something created by committee. And it's hard to understand as a crisis when we also hear scientists talking about ice ages and other natural changes to the climate happening throughout earth's history. "Global warming" is something people have worried about for years, though. It's essentially another term for the same thing, but conveys a planet-wide danger.
There's good evidence that global warming is exacerbating the wildfires raging in southern Australia, but when we call it "climate change," nonscientists may well wonder what the connection is and how it could have been averted.
