❄️ It’s freezing cold outside here in Germany, and this is an interesting explainer of why that is: a warming event in the polar region is leading to an early collapse of the polar vortex, so Europe and North America are flooded with cold air, while the North Pole is unusually warm. #weather #climate

TIL: DeHavilland Dash 8 aircraft have a much larger range than I thought. Just noticed an Air Canada Jazz flight from Vancouver to Winnipeg (JZA7110). That's about 1900km.
I look because turbo-props like the DH8 (aka Q400) are more fuel efficient and have lower CO2 emissions than jets. They also fly lower, generally around 20 - 25,000ft, so lessen the stratospheric pollution vs. 30-40,000ft.
