"Anthropogenic climate change at a rate that humans and/or natural systems can't cope with" just isn't as catchy.

Weather changes. Climate is the accumulated average across years. It’s “yesterday it rained here” vs “we got an average of x litters of water per square meter during this month in the last ten years”. Climate changes, but by its own nature it should change really gradually.

The point is that weather is changing so much that even climate is changing quickly now. Or, in a car metaphor: not only our velocity is increasing, our acceleration is also increasing m.

I think a stronger word like “climate emergency” would have been more appropriate.

Overall temperature increase is the part that is most directly caused by our activities, and which in turn causes all those other changes, so I think it's fair to emphasize that.

Weather changes. It's when enough weather changes that the overall climate changes where we begin to have issues.

Too subjective. Objectively climate has always been changing and will always be changing. Earth has seen much warmer climate and much colder climate and everything in between since formation. Your definition of issues don’t really make sense unless it’s subjective because objectively climate change is just is, not good not bad, just fact and consequence of complicated system. Even in the past many centuries, if you look at history, plenty of empires fell because of climate change(floods, droughts, etc). We are accelerating the change but it would still be changing even if we didn’t exist.

Well, the problem is that we are accelerating so much that adaptation from living beings is not possible.

Not a small problem,you know...

But 'drift' carries the idea that 2021 climate is already gone, and that we won't get it back anytime soon.

'change' doesn't carry this idea at all. Anyway, global warming was more descriptive, thus better to me.
