What is actually going to happen is displacement. The hundreds of millions of people most vulnerable to the consequences of climate change don't have much choice but to start walking. The 2015 refugee crisis in Europe was nothing compared to that, never mind the tiny trivial inconvenience that is current illegal immigration across the Mexico–US border.

Agreed. Europe struggled to relocate 2.5M of refugees over several years.

What happens when people from India, the middle east, ... are forced to relocate? I expect some kind of conflict/war of expansion and probably famine since a lot of the land will be abandoned and hence become unproductive.

I'd expect the land to become unproductive first. A huge amount of agricultural land is threatened by the climate change, accelerated by other anthoropogenic effects such as soil erosion due to deforestation. Besides drought, heat, wind, and excess rainfall, there's flash floods caused by melting glaciers in the Alps, Himalayas, …

True. And at that point I really believe unrest will be widespread. The saying "We are 3 meals away from anarchy" will prove its veracity.

I think Bangladesh is also scheduled for certain crisis.

And let's be real, no wall (or frontex and the like) will ever keep out billions of people. If the world doesn't get its shit together and respond globally and collaboratively now, this will get ugly beyond imagination and no one, no matter the edgy coldness of their x-first attitude, will come out of this recognizable. People won't just die politely, much less when informed about who's to blame for all this hell.

I think there may be even possible consequences beyond everyone's worst nightmares when we see massive ecosystem collapses. What is it gonna be like, if you have unimaginable fields of mold and bacterial overgrowth? The winds bring Sahara's heavy mineral dust to Europe now, I am sure spores and toxic particles fly much better tomorrow...
