It’s the proper term for what people “loosely” refer to as “Global Warming”. Just global warming is not the right term to use — because — “global warming” is true. It’s Anthropogenic Global Warming which is not true (which is “man-made” global warming).
That’s why you should distinguish between the two in order to “firm up” your arguments — otherwise, they are all muddied-up...
Ah, I totally understand. Thanks. :)
