Nuclear winter is studied heavily, which could result in dramatic population decline. But then after a decade or longer the nuclear summer kicks in – which would thwart the capabilities of natural ecosystems to cope when exposed to high levels of UV-C radiation. This would also increase the time greenhouse gasses would prolong in the atmosphere. And then we have the large climate inertia and possibly a higher climate sensitivity than previously thought. Earth energy balance needs to be restored, either naturally over many millenia or by human intervention (reforestation, carbon sequestration and with the help of carbon negative technologies).
