It’s funny because here in Austria right now in August I need my sweater in the morning. Very much not normal. (Not that I mind it being cool, but it’s worrying.)
Due to climate change, the polar vortex is very unstable. It used to be that there was the Jetstream around the North Pole, keeping the cold air there, and only sometimes it would make a U-shape down towards europe (or other parts of the world) but due to global climate change it’s extremely unstable and squiggly at times, meaning that sometimes in summer the cold polar circle air extends towards Europe, as we have it right now.

I‘d like to post the studies as well but I can’t find them this quick.
