How long will a nuclear winter last?

These models predict that global temperatures would drop to an average of just above freezing year-round, lasting for around 10 years. Limited effects would linger on for many decades past the initial nuclear winter, potentially disrupting food production for a whole generation.

These thick black clouds could block out all but a fraction of the Sun’s light for a period as long as several weeks. Surface temperatures would plunge for a few weeks as a consequence, perhaps by as much as 11° to 22° C (20° to 40° F).

What US cities are most likely to be nuked?

What is the kill radius of a nuclear bomb?

Death is highly likely and radiation poisoning is almost certain if one is caught in the open with no terrain or building masking effects within a radius of 0–3 km from a 1 megaton airburst, and the 50% chance of death from the blast extends out to ~8 km from the same 1 megaton atmospheric explosion.
