You seem to assume that the temperature will slowly increase, giving us time to adapt, without descending into another global war due to all the shufling of agricultural areas and mass migrations.

But there's a scarier scenario, where temperatures change much more rapidly due to a positive feedback loop: https://en.wikipedia.org/wiki/Runaway_climate_change

The even more scary thing is our models are so bad that we have no idea of how likely a positive feedback loop is. We are basically driving down the freeway at 100 miles per hour with our eyes shut with the hope the road stays straight.
