Sea ice extent in the Arctic is mostly determined by prevailing winds and ocean currents. It probably is declining slightly over the years as natural increments in temperature and increased sunlight due to pollution control occur. But the natural ebb and flow is too small to get upset about; if it might even be good to have an open arctic for shipping purposes.
Arctic Sea Ice has most definitely declined over the past 44 years since accurate satellite measurements began in Sept 1979.
BUT. NOT in the pretty simplified straight extrapolation that the Global Warming narrative requires.
Rather, there a very brief high period of 1979, 1980, 1981-1982.
THEN, a marked decline of 22 years from 1984 through 2006.
Since winter 2006 - 2007, for now 18 years, there Arctic Sea Ice extents have been steady. No longer decreasing, not statistically increasing either. NOT continuing Al Gore’s simple grade school straight line decline that the NSIDC displays.
