Isn't the rate of increase slowing, though?
Depends what (only official UN prognosis or ones by independent experts) and when you compare it to, and projections reaching more than one generation into the future are all highly speculative anyway.
It's true that it's now projected to decline faster than it generally was in the 2010s (apart from Jørgen Randers' technology optimistic one from 2012), but it wasn't that long ago (2004) that the global population was projected to stabilize just shy of 8 billion in the mid 2070s, now it's sometime in the 2080s and at nearly 10.5 billion and it's very uncertain that population growth will decline fast enough in the Islamic world and sub-Saharan Africa to reach that. What seems certain is that it won't start actually dropping fast enough to stop climate change and the budding resource crisis from getting a lot worse since resource consumption and emissions per capita keep rising. It's not really enough to stop the global population from rising you'd need it to actually start declining and ideally a couple of generations before it's likely to do so, so we're still ed. Unless some major and highly virulent pandemic start to cull the herd.
