It probably mentioned the 60 million or so Bangladeshis that will be looking for dry land to live on.
When this really kicks off there will likely be war between India and China over water in the Himalayas if not Taiwan to distract the Chinese general population.
They have already lost a lot of their crops this year due to flooding
Massive movements of millions of people seeking habitable land. ( Do you know anywhere near Asia with lots of empty space?)
Agricultural collapse, water wars and disruption worldwide…
It will make the boat people nonsense of the past 2 decades look like a nice walk in the park.
So nothing to see here really.
