Anthropogenic Climate Disruption (ACD) - blue ocean event - Update

Arctic sea ice extent on May 15, 2016 was 11,262,361 square km, 1.11 million square km less than it was on May 15, 2012. Since April 2016, sea ice has fallen far, far below anything we've seen in earlier years.

It is the rate of change that is the most frightening. NOBODY saw this coming.

The Arctic could likely be ice free by September.
Climate scientists tracking anthropogenic climate disruption (ACD) have long feared what is referred to as a blue ocean event. A blue ocean event means a complete absence of Arctic sea ice, allowing the heat of the sun to fully penetrate the open waters of the Arctic, which would then dramatically accelerate the rate of warming in the Arctic.

80 percent of the sunlight that strikes sea ice is reflected back into space. As sea ice melts in the summer, it exposes the dark ocean surface. Instead of reflecting 80 percent of the sunlight, the ocean absorbs 90 percent of the sunlight. The oceans heat up, and Arctic temperatures rise.
New research finds that Arctic sea ice loss is causing the jet stream to weaken and high-pressure systems to get stuck in places like Greenland, leading to accelerated melt of the land-locked ice that drives sea level rise.

Changes are taking place to the jet stream. As the Arctic warms up more rapidly than the rest of the world, the temperature difference between the Equator and the North Pole decreases, which in turn weakens the speed at which the north polar jet stream circumnavigates the globe.
