Jet Streams are so wavy in the Northern Hemisphere that in the last few years, wave crests have brought warm air and rainfall (above freezing temperatures) to the Arctic’s North Pole in the dead of winter, & wave troughs are crossing the equator. Now it is the Southern Hemispheres turn. Slower, wavy, wide, space-filling Jet Streams are bringing warm air, and even rainfall to Antarctic coastlines in the dead of winter. Look for yourself, and be amazed and awakened.
“Almost no thick ice left in the arctic.”
