I don't buy this particular flavor of thermonuclear war scare tactics because the math doesn't add up. World's entire nuclear arsenal adds up to a couple of gigatons, while the Mt. Tambora eruption in the 19th century alone was estimated to release 30 gigatons equivalent of energy.

The havoc a nuclear war would wreak on civilization is already bad enough merely through destroying infrastructure.

The mere energy wasn't the fear; the fear was nuking cities in particular would create the kind of dust that would get stuck at high altitudes, and put it at those high altitudes.

I think this is… no longer a widely held fear. Though I don't know if that change is for good reasons or bad reasons.
