Extreme blasts of freezing weather hitting Europe and the USA in recent years aren’t caused by a warming Arctic changing the jet stream, as previously thought.
Research by the University of Exeter disputes earlier studies suggesting a warming Arctic was creating a ‘wavier’ jet stream and linked to climate change.
They found it’s more likely the other way around with random fluctuations in the jet stream warming up the Arctic over decades.
This is a classic case of Occam’s Razor. It has always been blindingly obvious that a wavy jet stream will push warm air into the Arctic, thus raising temperatures there. So why on earth is there a need for scientists to prove the opposite relationship?
Perhaps instead they could do something useful, such as finding out what causes these changes to the jet stream in the first place.
