Jet stream 'crosses' the equator

Jet stream 'crosses' the equator

A post about the jet stream now crossing the equator, published by Robert Scribbler yesterday, is making a lot of noise on social networks today.

In his post, titled "Gigantic Gravity Waves to Mix Summer With Winter? Wrecked Jet Stream Now Runs From Pole-to-Pole," Scribbler writes:

"The Jet Stream now has redefined all boundaries — flowing at times from the East Siberian Sea in the Arctic across the Equator and all the way south to West Antarctica. 

That’s bad news for seasonality.

Prevention of mixing of air between Hemispheres by the thick, hot tropical air mass is what has generated a strong division between Summer and Winter during the Holocene Climate Epoch.

However, erode that boundary and you get more Summer heat spilling over into the Winter zone and vice versa. 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."

Later on, Paul Beckwith, a part-time Geography professor (climatology, oceanography, environmental issues) at the University of Ottawa, published this video, explaining what's going on, from his perspective: 

"Our climate system behavior continues to behave in new and scary ways that we have never anticipated, or seen before. Welcome to climate chaos. We must declare a global climate emergency," Beckwith concludes.

Jason Samenow (Capital Weather Gang/Washington Post) reached out to several atmospheric scientists, who have graduate degrees and are trusted sources in the profession, for their reaction to these claims. 

"Without exception, they said air flow between the hemispheres is not at all uncommon," Samenow writes in his article titled Claim that jet stream crossing equator is ‘climate emergency’ is utter nonsense.

July 2

Scribbler reacted to Samenow's article and claims made by Beckwith. 

"... The message in my article is that the situation appears to be worsening and that this particular global climate crisis may be something that we’ll face over the coming years and decades. The article was intended to highlight the risk posed by weakening dividing lines between climate zones, an apparent observed increase in meridional upper air patterns, and in this case, an observation of the upper-level wind pattern that crossed from pole to pole.

As I mentioned in my article, large meridional upper-level wind flows and related extreme weather, along with what appears to be a growing trend toward a loss of seasonality is a very big deal. Apparently, not everyone agrees with me on this point. Regardless, the concern over loss of seasonal variation due to human-caused climate change remains an issue. ...

In closing, I must gently disagree with the assertions Mr. Samenow put forth in his opinion piece. On the contrary, it is the height of responsibility to highlight issues that so many others have tended to ignore or discount at great risk to our global civilization. ..." See Scribbler's article and full update, here

There was another interesting piece related to the topic. In an article titled "Lessons From 'Jet Stream Crossing The Equator' Mania" (July 2, 2016 - Forbes), Dr. Marshall Shepherd says: "My intent here is not to attack or discredit the scientists involved in the initial claim but to provide a few lessons as we move forward addressing the very serious changes in our climate system. ... 

Even with the jet stream discourse my first inclination was to tweet urging caution and let scientists vet the claim. Perhaps the final and most important lesson is that even if you think someone is wrong or you disagree, the discussion should be had without vitriol or seeking to personally tear down an individual."

Lets discuss the Polar shift and the tilting of the Planet , which would move the jet stream to be eradic behavior. Its part of geology/astrology but no one in any government funded or Nasa agency is going to tell the truth about the " Blue Planet". I studied enough geology at U of Wisc to understand this Catastrophic Event. I just didn't think it would happen in my lifetime, as Geologic time is usually hundreds of thousands of years.

I don't think a polar shift has anything to do with astrology. The physical positions of the poles never changes. The tilt of the earth has always been the same. Gravitational fields are the only thing that changes. You're compass might move but the stars are always going to be in the same place. I haven't heard anything about what this does to weather patterns though. I'll look into it more. Gravitational north has moved to Russia and airports have had to adjust coordinates on the runways.

Its funny to me how these "scientists" can look at this phenomena independently of all other climate change indicators. I am talking about increase earthquake activity, volcanic activity, sun rise and sunset times not matching up to anticipated times, mass animal kills, crop failures, and of course extreme weather. I could go on and on, but the point I am making is that the rational explanation is that of the nearby planet x. http://poleshift.ning.com/

No, the solar systems center lined up with the center of the galaxies center, many years to a peak on Dec 21, 22, 23 then after that the energies coming in from that direction are shooting threw the solar system at a different angle now. This is making planets to leave the solar system and a reverse vibration twist on earth. Weather channels changing, north and south poles melting, sink holes, earthquakes, plates moving faster, etc. It is not planet X. That is a hoaxs. One of Plates seven sisters even left the solar system. Venus slowed down by minutes of spin time. God will not have this solar system saved for tech remote mind control by others. That is occurring. Yes it is alien. High tech communications has put a web over our heads. Read the book "Project Lucid" by Texx Marrs. Written in 1996. Read page 187 to the back and the foot notes first, then front to back. We are under attack.

Sorry, I forgot to put the peak year. It was 2012.

ALL THIS MAY NOT BE THE REAL REASON FOR GLOBAL WARMING. PERHAPS THE POLAR AXIS IS LESS THAN 23.5 DEGREES TO THE PLANE OF THE ECLIPTIC, DUE TO MOVEMENT OF ASTRONOMICAL BODIES EFFECT

Can the spot you show us can be the Island of plastics sitting in the middle of the Pacific? I mean the jet stream cross over because of the heat generate by this area ?

Changes in weather conditions probably occur as a result of this phenomenon across vast areas.
