Should we panic?! ‘Unprecedented’: Scientists declare ‘global climate emergency’ after jet stream crosses equator

-

Should we panic!? Warmists declore ‘climate emergency’! 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.”

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.”

Climatologist Dr. Roy Spencer smacks down warmist jet stream claims as ‘silly: Spencer: ‘There is frequently cross-equatorial flow at jet stream altitudes, and that flow can connect up with a subtropical jet stream. But it has always happened, and always will happen, with or without the help of humans.’

Spencer continued:

Paul Beckwith has a masters degree in laser optics, which he has somehow parlayed into being a “Climate System Scientist” to spread alarmism about the climate system.

But his post “Unprecedented, Jet Stream Crosses Equator” suggests he knows little of meteorology, let alone climate.

A “jet stream” in the usual sense of the word is caused by the thermal wind, which cannot exist at the equator because there is no Coriolis force. To the extent that there is cross-equator flow at jet stream levels, it is usually from air flowing out of deep convective rain systems. That outflow often enters the subtropical jet stream, which is part of the average Hadley Cell circulation.

There is frequently cross-equatorial flow at jet stream altitudes, and that flow can connect up with a subtropical jet stream. But it has always happened, and always will happen, with or without the help of humans. Sometimes the flows connect up with each other and make it look like a larger flow structure is causing the jet stream to flow from one hemisphere to the other, but it’s in no way unprecedented.

We’ve really only known about jet streams since around WWII…one of my professors, Reid Bryson, was one of the first to advise the U.S. military that bombers flying to Japan might encounter strong head winds. The idea that something we have been observing for only several decades on a routine basis (upper tropospheric winds in the tropics) would exhibit “unprecedented” behavior is rather silly.

I especially like this portion of Paul’s post:

“We must declare a global climate emergency. Please consider a donation to support my work..”

Nice touch, Mr. Beckwith.
