Watching The Arctic Die - 2

Fig. 1 NSIDC graph
Yesterday's post had two graphs of the sea ice in the Arctic, which, as Fig. 1 shows, continues on a record breaking path.

One scientist says there is a climate emergency (A Climate Emergency).

Another says the situation is ridiculous: “​The ridiculously warm temperatures in the Arctic during October and November this year are off the charts over our 68 years of measurements,” Jennifer Francis, a climate scientist at Rutgers University who studies the Arctic, said (Climate Central).

Today, let's look at the WOD Zones above Latitude 80 North, which are 1800-1817 and 7800-7817 (Fig. 2, above red line at top of graph).

Fig.4 Antarctica has an impact on Arctic SLC
I made a graph from the WOD record of temperatures from 1977-2016, which shows suspect warming since 2012 (Fig. 3).

A previous post mentioned warm water flowing from "The Blob" into Arctic regions (The Question Is: How Much Acceleration Is Involved In SLR? - 4).

That warmer water combined with the warmer air makes for not only ice extent shrinking, but also for sea level fall (SLF) as shown in Fig. 4.

Fig. 5 Greenland SLF & SLR impact

The greatest sea level change in the area is caused by the melting Greenland ice sheet (Fig. 5)

But as the Arctic sea ice melts it will be relocated toward the equator to cause a wee bit of sea level rise (SLR) there.

That wee bit will be added to the much greater amount also relocated there, caused by both Greenland ghost-water and melt-water (The Ghost-Water Constant, 2, 3, 4, 5, 6, 7).

This is, of course, because the ocean is not a bathtub (The Bathtub Model Doesn't Hold Water, 2).

The graph at Fig. 4 shows not only the SLF caused by Greenland ice sheet demise, but also the SLR that Antarctica's demise causes there in the Greenland area (Fig. 6).

Ice sheets and glaciers have an impact on the sea level at other ice sheet and glacial areas that are near the ocean.

In other words, as the Greenland ice sheet melts and calves away, its gravity decreases which releases water around it to move toward the equator and raise water level even all the way down to Antarctica.

That replaces some of the water that is released from Antarctica as its ice sheet 
melts and calves away (each adds to the other).

Another factor of the dying Arctic is the demise of the polar vortex:
Under normal climate conditions, cold air is confined to the Arctic by the polar vortex winds, which circle counter-clockwise around the North Pole. As sea ice coverage decreases, the Arctic warms, high pressure builds, and the polar vortex weakens, sending cold air spilling southward into the mid-latitudes, bringing record cold and fierce snowstorms. At the same time, warm air will flow into the Arctic to replace the cold air spilling south, which drives more sea ice loss.
(Watching The Arctic Die). The sad part of this is that we are watching our world be murdered by a private empire of psychopaths (MOMCOM: The Private Parts, 2, 3, 4, 5; Smoke & Fumes).
