How to treat the recent high temperature of 38℃ in Hoyansk town in the Arctic Circle? .

On June 20th, the highest recorded temperature of -38℃ appeared in the Arctic Circle town of Jansk, Vilho. As one of the top ten extremely cold places in the world, the average temperature in Jansk, Vilho in June is 20℃. Meteorologists and climate experts say that this kind of high temperature is unheard of in the Arctic Circle and should not appear until about 80 years later. On 2 1 day, the temperature in the same place is 35.2℃. (financial network). It belongs to abnormal high temperature weather caused by blocking high pressure, which is more common in meteorology, so there is no need to make a fuss. As for whether it has anything to do with global warming, there is not enough evidence. The detailed explanation is as follows.

Last summer, abnormal high temperature weather caused by blocking high pressure occurred in northern Europe, and high temperature above 30℃ occurred in Norway in the Arctic Circle. Whether it is the abnormal high temperature in Siberia now or in northern Europe last year, many media (even some official media) directly attribute it to global warming, accelerated warming in the Arctic (Arctic amplification effect), melting of Arctic sea ice and other factors. The logical explanation is nothing more than "global warming, especially the accelerated warming of the Arctic, and the melting of sea ice, leading to more and more high-temperature heat wave events in mid-latitude areas (that is, the risk is increasing)". Then the topic turned to greenhouse gas emission reduction, saving polar bears, saving ecosystems and even saving the earth (the earth has lived for 4.5 billion years, and we really don't need to save it! )。 However, as a reader, from the point of view of logical reasoning, I have never understood how global warming caused the unusually high temperature weather in Siberia.
