Paul Beckwith of the University of Ottawa declared the Arctic ice-free in 2013.

Now he is back declaring a “global climate emergency” because the “jet stream crossed the equator.”

‘Unprecedented’: Scientists declare ‘global climate emergency’ after jet stream crosses equator
Dr. Roy Spencer explained why this is complete nonsense, and showed that Paul Beckwith understands nothing about climate or meteorology.
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.
Beckwith’s stupidity rates right up there with Al Gore’s northern hemisphere hurricanes rotating clockwise.
Climate alarmism has nothing to do with science. It is driven by fraudsters seeking money.
