A nuclear winter might be arguably better for the long term survival of the human species than an uncontrolled thermal runaway from global warming. Previous ELEs either ejected seeds-of-life into LEO or were Ice Ages, not hot ages. The oncoming arctic methane positive-feedback loop looks "interesting".

I find it very unlikely that a total collapse of modern civilization in addition to poor, irradiated harvests due to nuclear winter is easier to survive than poor harvests and extreme weather while having access to modern technology.

Survival is that of the Earth, not people. Nuclear winter could stop uncontrolled thermal runaway, which would have a worse outcome than nuclear war.
