eurojosh Posted June 30, 2016 Share Posted June 30, 2016 Came across this story today - no idea whether it is (a) unusual or (b ) significant to see this kind of transequatorial jet stream. Can someone explain and chime in? http://www.rawstory.com/2016/06/unprecedented-scientists-declare-global-climate-emergency-after-jet-stream-crosses-equator/ ‘Unprecedented’: Scientists declare ‘global climate emergency’ after jet stream crosses equator David Edwards Climate scientists this week expressed alarm after “unprecedented” data showed the Northern Hemisphere Jet Stream crossing the Equator. In a column on Tuesday, environmental blogger Robert Scribbler noted that the Northern Hemisphere Jet Stream had merged with the Southern Hemisphere Jet Stream. “It’s the very picture of weather weirding due to climate change. Something that would absolutely not happen in a normal world,” he wrote. “Something, that if it continues, basically threatens seasonal integrity.” “Like many extreme events resulting from human-forced climate change — this co-mingling of upper level airs from one Hemisphere with another is pretty fracking strange,” Scribbler explained. “Historically, the Tropics — which produce the tallest and thickest air mass in the world — have served as a mostly impenetrable barrier to upper level winds moving from one Hemisphere to another. But as the Poles have warmed due to human-forced climate change, the Hemispherical Jet Streams have moved out of the Middle Latitudes more and more. ” “That’s bad news for seasonality,” he continued. “You get this weather-destabilizing and extreme weather generating mixing of seasons that is all part of a very difficult to deal with ‘Death of Winter’ type scenario.” University of Ottawa climate scientist Paul Beckwith called the new behavior “unprecedented.” “Our climate system behaviour continues to behave in new and scary ways that we have never anticipated, or seen before,” Beckwith observed. “Welcome to climate chaos. We must declare a global climate emergency.” In a YouTube video, Beckwith said that the jet stream behavior signaled “massive hits to the food supply” and “massive geopolitical unrest.” Link to comment Share on other sites More sharing options...

Jonger Posted June 30, 2016 Share Posted June 30, 2016 I'm not sure what his angle is. He has a motivation to hype everything, which hurts credibility of real scientists. Link to comment Share on other sites More sharing options...

eurojosh Posted June 30, 2016 Author Share Posted June 30, 2016 I appreciate the inputs on the credibility of one of the scientists in the report... As an uninformed non-scientist, I'd still welcome an explanation of whether this is accurate, if accurate unprecedented, and if unprecedented, significant?

There was nothing compelling in the article from an empirical standpoint. A lot of anecdotes...and some of the explanations or quotes don't make a whole lot of sense either. Scribbler mentioned that jets are moving out of the mid-latitudes due to polar amplification...which would be fine except he's talking about stuff near the equator and Jets would be moving poleward due to polar amplification rather than closer to the tropics. They would also become weaker due to decrease thermal gradient. Link to comment Share on other sites More sharing options...
