Nuclear Winter (2)

Editor’s Note: Please refer to previous post for a correction as noted in the Editor’s Note.  Last week’s post reviewed the basic science of nuclear winter – the short version is that the explosions themselves will put many tons of dust into the atmosphere, and the fires that are started by the nuclear explosions will […]
