The greater concern that is being commented on is that in the far north, the summer temperature is about 10 degrees hotter. This is supposed to be melting the permafrost which releases a lot of CO2. Also it appears that for at least some arctic river systems, there is a lot of frozen methane deposits that are now being released and methane gas is said to be more dangerous than CO2 gas.
I am afraid that your information is both distorted, dated, and has been refuted.
The sea ice extent at the North Pole is essentially back to what it was ten years ago. The temperature data has been repeatedly “extrapolated” from sensors up to thousands of miles away in many cases and easily manipulated. You are repeating alarmist propaganda. I do not have time at the moment to post links, but they are out there if you care to look at this a little closer.
