Given the current trajectory of whale populations, 'we' probably won't be seeing that. Maybe in many generations of humans.
Well, the population growth probably isn't linear, so maybe?
Warming will kill off most of the systems these animals depend on within 30 years.

And will give way to many which thrive or evolve to thrive in hotter climates?
It's gonna take a minute (on a geological timescale) for the ecosystems to be able to reliably sustain megafauna again.

#25I hope we create whalegemma (similar to dolphingemma) so we can explain to them how to co-exist better with humans (e.g. avoid this area during their whale hunting season, travel to this area if you get sick or tangled in rope).
There is a group that is attempting to communicate with whales by training a transformer based model on whale sounds. https://www.projectceti.org/

Given that we support megafauna today, could you explain why? Legitimately asking, since I don't see a reason they couldn't adapt just as well.

Because evolution is slow and the climate change is going fast.

#28holy units batman > Bursting from their enormous lungs at over 300mph (483km/h), a humpback whale's blow can rise up to 7m (23ft) into the air. Pick a lane BBC. But this is great news. Also the fact that whales "transport huge amounts of nutrients across the globe" (linking to [1]) is fascinating. The role of whales in sucking up critters in one place and pooping them out elsewhere being a fundamental dynamic that dr…
Apparently they also measurably affect the vertical water mixing. Fish need dissolved oxygen to breathe, so they don't normally venture past the thermocline. And their fins are also vertical, so they don't cause a lot of vertical water movement.
But whales routinely dive deep, and their tail fin is _horizontal_ and it creates powerful updrafts.
Another organism that affects mixing is apparently jellyfish.
