That is above most cities and alone will be an issue. The soot is lowering tge remaining ice's effectiveness which means more hear trap. The paper's premise was what Carter was doing for us over 40 years ago. If we'd followed his goals plus made a big push to reduce heating and cooling energy consumption we might have been able to address species migration. Now each year will be ever worse and some time very soon much of that methane will release and average temps will go up tens of degrees. I've seen 10 centigrade as the estimate, which happened in about a dozen years during the Permian extinction
