Bee-covered sodomising asteroid: is the use of the term “nuclear winter” here because

i) this has become a real actual science name for any long-term post-explosive atmospheric temperature drop.

ii) this has become a lazy shorthand for any etc etc.

iii) the BBC want to hint that our humble pollinating friends could survive a nuclear war and become masters of the Earth.

iv) the BBC know something we don’t* about the fate of the dinosaurs!

*(unless we have been diligently reading our 2000ADs that is.)
