New paper finds modern sea ice coverage in Canadian Arctic near highest levels of past 150 years

The Hockey Schtick
"A new paper published in the European Geosciences Union journal Biogeosciences reconstructs sea ice coverage in the Beaufort Sea of the Canadian Arctic over the past 150 years and finds modern sea ice coverage [9.4 months per year] is significantly greater than during the period from ~ 1887-1945 [8.3 months per year]. Figure 4 of the paper shows modern sea ice coverage is amongst the highest levels of the entire 150 year record. The authors find that the reduced sea ice coverage from ~1887-1945 corresponded with reconstructed sea surface temperatures that were up to 3C warmer from 1885-1935 in comparison to the average modern temperature. According to the paper, sea ice coverage was dominated by natural variation from the Pacific Decadal Oscillation [PDO] and Arctic Oscillation [AO]."
