Sure, only 80% of say the maldives by the time my kids are my age.
I wonder what Americans would do if other countries worked together to put every single state apart from Alaska and half of Texas underwater in the next generation.
2050 is a 10cm rise from today. I expect most of the Maldives is already "uninhabitable" (and always was) by whatever standard is being used there.
You could literally dredge up land 100x faster than sea levels rise for the Maldives.
There are many nasty consequences of global climate change, sea level rise is an irrelevant distraction from things like India heating up and ocean acidification.
