Arctic ice is presently 266.000 km^2 more than in 2007, and 1 million km^2 more than the record setting 2012.
Mid September we can see the long predicted collapse of Arctic ice is postponed for yet another year. The graph shows MASIE reporting ice extents above 4.5M km2 for the last two weeks. A dip on day 252 to 4.43M km2 will likely be the daily minimum for the year. The graph also shows that 2018 is presently close to the 11 year average ice extent, 233k km2 more than 2016, 266k km2 more than 2007, and 1M km2 (a full Wadham!) more than the record setting 2012.
Interestingly, in September NOAA’s offcially referenced Sea Ice Index (SII) is showing more ice than MASIE, by about 200k km2. That means the SII September monthly result will continue the plateau in Arctic ice since 2007.
As reported previously, the Northwest Passage through Nunavut was closed this year due to excessive and thick multiyear ice blocking the way. The chart below shows the conditions as of yesterday.
It won’t get any better than this for yachts attempting the passage west, since more than 3/10 (green) ice conditions blocks their progress.
