~The speed of change is dramatic, considering average warming by 1 C average use to take hundreds of years.
~Arctic weather is morphing with respect to a warmer North Pole
We look at recent CTNP vortices, those coldest centers of the Polar Vortex, at 600 mb pressure level, representing the temperature of the entire troposphere, and find remarkable avoidance of the Arctic Ocean for having a Cold Temperature North Pole, as surmised in previous articles, they were interspersed, small, fleeting, if any at all, while similar over land at least lasting longer in duration or more stable:
Here we split the climate scenes made obvious in less than 30 years, one in the 1970's and the other in last few years. The contrast can't be more clear, since 2007, the Arctic Ocean seems to have been cleared of CTNP's, while in late 70's it was 5 February 11's out of 6 which had CTNP presence, rather than 1 out of 7 for 2007, 2016, 2018,2019 till 2022 same day. The importance of taking a single day is not trivial, since the area involved is huge, given same atmospheric chemistry, the odds are somewhere during the same day the temperatures would be similar. Arctic Sea ice not as thick, not as insulating from said but now warmer Ocean, giving a different circulation pattern for the entire Northern Hemisphere, which has not given pleasant or comfortable weather conditions in certain key locations of our planet.
