: Scientists Declare Global
Climate Emergency After Jet Stream
Crosses Equator
It's something that "would not happen in a normal world."

Climate scientists this week expressed alarm after
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
“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

Scientists warn of 'global climate
emergency' over jet stream shift
Experts say drastic weather changes could cause 'massive hits to
food supply' and 'death of winter'
The two scientists warn of 'climate chaos' to come as the stream shifts Paul
Beckwith
Environmental scientists have declared a
after the Northern hemisphere jet stream was found to have
crossed the equator, bringing
changes to the
world’s weather patterns.
Robert Scribbler and University of Ottawa researcher Paul
Beckwith warned of the
consequences of the jet stream shift.
The scientists said the anomalies were most likely precipitated by man-made climate change, which
caused the jet stream to slow down and create larger waves.
Scribbler wrote in a post on his environmental blog on Tuesday:
The blogger explained the barrier between the two jet streams generates the strong divide between
summer and winter, and the
could commence if it is eroded as warm weather leaks
into the
of the year.

Meanwhile, Mr Beckwith confirmed the changes would usher in a sustained period of

There are two forms of jet streams - polar and subtropical - and the northern and southern
hemispheres have one of each.
The streams are the products of atmospheric heating by solar radiation and kept in place by the force
of inertia.
