I see a 6° rise pushing the few survivors to the poles. There will be mass die off, most likely a lot of nasty fighting in the prelude. In that interim most infrastructure will be destroyed. The victors will have a hard time defending against the loosers who will want to take revenge and who will be desperate.
But even if dams and turbines survive who maintains such things? So presuming hydro power, unless you mean on a personal basis, is presuming a technological base that barely exists in the USA at this moment.
There will be no acient landfills in the habitable zone.
Of course none of us actually KNOW what will come, all mindless speculation.
That should be idle speculation not mindless.
Niagara falls and the La grand four on James bay would both be in or on the southern edge of the habitable zone. We could send maintenance teems to do major repairs in the winter months and house necessary staffing in air conditioned buildings. Landfills could also be mined in the winter or by robots. The boreal forest of Canada and Siberia would become deciduous and the growing degree days sufficient for many of our crops.
We can make do with whatever is left to the survivors. It is getting through the transition that will be the hard part.
