100.4 degree Arctic temperature record confirmed as study suggests Earth is warmest in at least 12,000 years

I suggest reading the whole article at the following link. There is so much important information, I would have to include pretty much the whole article, which would not be ethical to violate their copyright.

Less than two weeks ago, the small Siberian town of Verkhoyansk soared to 100.4 degrees Fahrenheit, appearing to break an all-time record for the Arctic and alarming meteorologists worldwide. Now that temperature record has been verified by Russia's state weather authority.

The confirmation came the same day a comprehensive new study was released suggesting that present-day global temperatures are the warmest they have been in at least 12,000 years, and possibly far longer. The study used a variety of geological clues and statistical analysis methods to reconstruct ancient temperature estimates.


Ten days after that record was set, the heat wave still persists. On Tuesday, a town in the Sakha Republic, 450 miles north-northwest of Verkhoyansk, and also 450 miles north of the Arctic Circle steps from the Arctic Ocean's Laptev Sea, hit an astonishing 93 degrees Fahrenheit. That's 40 to 45 degrees above normal.


The record heat in parts of Siberia during the month of May was so remarkable that it reached five standard deviations from normal. In other words, if hypothetically you were able to live in that area for 100,000 years, statistically speaking you should only experience such an extreme period of temperatures one time. Climate change has now increased that chance.


There may be an additional impact from climate change. Dr. Michael Mann is arguably one of the world's most respected climate scientists. In 2018 he published a study about a summer phenomenon he calls quasi-resonant amplification (QRA) in which atmospheric waves and jet streams tend to slow down or even get stuck, leading to a blocked pattern. This effect is most pronounced with more warming.
