Europeans have already noticed a "big difference" in the influx of Syrian and Afghani refugees. That invigorated anti-immigration parties, but those parties also advocated for various policies that went beyond immigration. A few million people had a huge impact on politics overall.

Now imagine the turmoil and political ramifications that could spring, even in the short term, from the flooding of Bangladesh and the migratiom of its people towards the global north.

Bangladesh already suffers catastrophic floods and is already being exacerbated by human influences: https://en.wikipedia.org/wiki/Floods_in_Bangladesh#Coverage_...

Small changes that we'll see well before the end of this century will have huge consequences. Don't be surprised if the country doesn't exist at all by the end of the century.

Not sure what you're point is unless to say that this problem is on a long enough time horizon (where the survival rate for everyone drops to zero ...).
