RE:Rare Fall Sudden Stratospheric WarmingInteresting and informative.
If you watched the 45 min. video I posted it expands this information to include what other weather events make all this possible.
It also explains the reason we can expext cold weather events here in NA
Beyond that is a study of planet movements.
The moon does influence tides and Jupiter has 19,500 times the gravitational pull than does earth.
You can imagine that when it moves closer to the sun it has an effect on solar events, solar flares and the strength of radiation.
Really to say all this climate change is man made is so mis informed and works to huge political advanage.
