How does this have any bearing on current *global* warming?

Stephen, I hope my A level students will rationalise that warming in
Scandinavia might just be more than a localised event, mirrored
perhaps in the UK, so certainly of continental proportions, long
before fossil fuel burning became an issue.

Let them think it through themselves - it is a debate after all, isn't
it? There are no certainties in this argument, and it may take
hundreds of years to resolve this issue.

I will pose your question to them however!
