Here in Lithuania we had one day below -20c this winter. Usually we have at least one or two weeks like that. Now the snow has melted and it's spring, feels around 6 weeks too early.
That applies in both directions and that was a response to someone saying it was warm in Copenhagen. I definitely do not doubt climate change but a warn winter in Copenhagen or a cold one in Oslo/Stockholm isn't climate, that is weather.
Same for Romania, or close to the record, anyway. I don't remember any month of February where we had 20 degrees Celsius in mid-February, and I'm in my 40s.
Depends on your definition of summer: if you apply your expectations from an August holiday in southern France to August in the UK, that is your fault!
