On a different track, but related as I stumbled across it while looking to see if any such numbers had been found for Australia.
https://en.wikipedia.org/wiki/Dansgaard%E2%80%93Oeschger_eventWhich leads to an interesting off-shoot which we'll have to see play out in the next decade.
Fact: A lot of the "temperature anomaly"(warming) being witnessed by satellite record is largely located in the Arctic Ocean.
Fact: The Northern Polar ice cap has been virtually non-existent during much of the year for several years now.
Fact: Liquid water is generally going to be warmer than cold water.
Fact: Frozen water is less dense than liquid(warmer) water.
Fact: Arctic Sea Ice is understood to have been melted in large part by way of incursion of warm Atlantic Water into the Arctic over several decades. Effectively melting it from below while warmer environmental conditions likely helped melt it from above. (But mostly, it was melted from below, water has a MUCH higher heat capacity than air)
Theory: Arctic Sea Ice was serving as a "cap" on top of warmer water in the Arctic which accumulated over time as it slowly melted its way through the polar ice cap.
Theory: The loss of said Sea Ice has now changed the thermal exchange from involving the melting of sea ice blown in from other parts of the Arctic and now involves a significant ocean-to-atmosphere-to-space interface, which is being observed as warming by orbital and ground instruments.
Theory: This heat exchange was previously unobserved because it normally happens under the ice sheet, which the Atlantic inflows overwhlemed.
Theory: Atlantic flows were particularly warm and strong due in large part to solar irradiance thanks to a series of very strong solar cycles.
Theory: The "Arctic heat" being observed isn't actually evidence of warming in the strictest sense. It is actually evidence of the ocean cooling as it releases heat energy it has stored over the intervening years.
Which brings us to another fact: The flow of warm water from the Gulf of Mexico to the Atlantic and thus to the Arctic has
been in decline since 2007.
Theory: As the Arctic completes releasing the accumulated heat energy(as the energy in flow is decreasing), the ice cap will begin to stabilize and grow back to what the activists are comparing it against.
Also of note: Some studies are starting to concern scientists as it looks like the Energy Balance for planet Earth, in particular the Northern pole, is running into negative territory. Good news for cooling the planet, problematic for theories of AGW.
