That added to the global cooling that would occur (especially in the northern hemisphere) causing massive crop failure and potentially ports to freeze over the UK would be very hard hit. Hence my suggestion of current civilisation changing and lots dying.
Ice Brakers could be built pretty quickly if the goverment wanted to, along with more aircraft, I think there would some wars going on over food and fuel with the western countrys coming out on top,
