>scientists who study Earth's climate call themselves meteorologists
This is just incorrect. Meteorologists don't study Earth's climate, they study weather. Meteorologists don't use ice cores or tree rings for their research, they study much shorter-term fluid dynamics. Climate scientists do study climate, and not weather. The disciplines are related (specifically, they're under atmospheric sciences), but to dismiss either one as being less scientific is picking favorites despite all evidence to the contrary. I suppose you could use the synonym "climatology" if you want a word without "science" in it, but it seems like a pretty silly heuristic regardless.
