Blue Ocean Event Consequences
A Blue Ocean Event looks set to occur in the Arctic when there will be virtually no sea ice left. At first, the duration of this event will be a few weeks in September, but as more heat accumulates in the Arctic, the event will last longer each year thereafter.
Indeed, a Blue Ocean Event will come with accumulation of more heat, due to loss of latent heat, as a dark (blue) ocean absorbs more sunlight than the reflective ice, etc. Consequences will extend far beyond the Arctic, as shown on the image below that features Dave Borlace‘s Blue Ocean Top Ten Consequences.
Dave Borlace goes into more detail regarding these consequences in the video Blue Ocean Event : Game Over?
A Blue Ocean Event could happen as early as September 2019. The image below shows that Arctic sea ice extent on April 7, 2019, was 12.97 million km², a record low for measurements at ads.nipr.ac.jp for the time of year. By comparison, on May 28, 1985, extent was larger (13.05 million km²) while it was 51 days later in the year.
As discussed in an earlier post, this all adds up to further global warming that may eventuate very rapidly. The image below shows how a total rise of as 18°C or 32.4°F from preindustrial could eventuate by 2026.
The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.
