This is an excellent paper on the warming in the upper stratosphere and also the explanation of the decrease and increase in arctic ice. I want to thank David (the star man) for sharing this with me on twitter today. He understands my passion for getting the truth out the best way possible and this report is overloaded with valuable information.
This study goes over 11 year cycles from 1979-2016. It unveils that if SSN ( solar sunspot number) falls below 1.35,the Arctic warming extends from the lower troposphere to high up in the upper stratosphere and vice versa when SSN is above, plus so much more . I’ll leave the link for the paper in the link below for self study as this paper is a lot to take in.
