Click on the images to enlarge. The first map on the left shows in yellow the ice left in Hudson Bay. The last ice is usually piled against or near the south shore of the bay. It’s not unusual to have ice left in the bay in mid-late July. You can see the Arctic icecap…right to the edge of Alaska. You can see the ice on the Barrow, Alaska webcam – 24 hours a day in the land of the midnight sun (the sun won’t set in Barrow until around Aug. 2). For July 1-18, Barrow’s average temperature was 39.4° and that’s 1.5° cooler than average. The graphic on the right is the Arctic ice extent for the last four years. We’re still well below the average extent of 1979-2000, but there’s more ice now than on this date going back several years (graphic from the Danish Meteorological Institute). Temperatures were warmer than average this past winter north of 80° latitude, but they have been cooler than average since early May. Antarctic sea ice extent remains well above (2 standard deviations above) average.
