Record warm Arctic

Some of this might be to do with reduction in aerosols (SO2)

aerosols

Aerosols reflect sunlight back into space, causing some cooling. Because of the COVID19 pandemic there is less aerosol biproduct from industry, car exhausts and especially shipping etc. It is having a MAJOR impact on Arctic ice!

Thanks to DRAH for alerting me to this.

Look at the low ice extent—ice thickness is 2m max, not the 4-5m it used to be so imagine how low volume is!

We have lessons to learn, but we ignore them.

God said we are the most important creatures on Earth, apparently, allowed to do whatever we like because God said we could. Chosen of God.

Mother Nature is showing us quite clearly, this will be our death.

Bring it on Mother.

That is record breaking low ice extent. There has been a stable high pressure system over the Arctic meaning unrelieved sunlight and so high temperatures including water temperatures which accelerates the melt and the warmer water will be around for a while melting the bottom of the ice.

On the Canada-Greenland “coast” (Canadian Arctic Archipelago is where the thicker ice ends up—and “thick multiyear ice” is at most 2yo old and 2m thick at the most, not 5m thick like it used to be even a few years ago. So dramatic drop in ice volume, more sunlight hitting and being absorbed by the Arctic Ocean—before long mostly ice free summers seeing the Arctic Ocean warming, evaporating—major storms hitting middle latitudes.

Since the pandemic the weather reporting has become less accurate - reduction in air traffic, less maritime movement etc

Satellites still circling the world. Maybe it is the record heat and melt in the Arctic?

Very likely what is causing extreme weather is the lack or aerosols and vapor trails from jet planes. Less sunlight reflected, more sunlight reaching the surface.

We are, however, adding energy to the surface-atmosphere by increasing the layers of GHGs: H2O, CO2, N2O, CH4, CFCs.

Ice is thinner than it used to be—10m thick at times—at ≈ 2metres/6.5' thick. So the area is not very meaningful and a change from high pressure over the Arctic Basin is changing to low pressure and if that generates much wind at all al lot more thin ice will get pushed out the Arctic through the Framm Strait.

First three lines show how the ice has disappeared—403,000SqKm less ice than in 2000 to 2010! That is a lot.

Nearly 1,000 square kilometres less ice in the Arctic than in record year 2012! While melt will slowdown as high summer fades the sheer amount of heat added to the Arctic Ocean will see at least bottom melt continuing but a forecast return to clear skies and high barometric pressure will see more melting.

AGW is getting serious!

Huge fires in Siberia near the Arctic Ocean—heat, soot all melting more and more ice.

There ain't no stoppin' it now .. https://go.nasa.gov/39oSyYL
for the 1'st time in 10 days we get to see the unfolding horror of the Atlantic side . Pagophilus showed the damage north of FJL . I see it extends as far as can be seen .. 86.5'N . The state of the ice here is as bad or worse than the ice between Laptev and pole . Coupled with the video of Polarstern and the ice flow , I see no reason for any of the ice on the Eurasian side of the meridian 0/180' to survive .
this update has just been patched into worldview .. between G'land and the pole .. the hue of the blue has darkened and it is easy to see water between the rubble = trouble . It looks as if even here in the bastion of ice there is no defence . Looks like only 5% of the ice here would make it through a serious assault .. the whiter blocks and specks .

The greatest concern, it has gotten exponentially worse then many scientists had predicted.

Apparently the methane released by the permafrost is greater than what humans are producing!

The lack of aerosols is what is buggering up weather forecasting (according to the thread I have been quoting anyway.)

Max temperatures in the Canadian Arctic Archipelago (CAA) yesterday:



This is in the Arctic circle!

The importance is that the channels of the CAA used to be blocked by thick ice. When they are clear they comprise what is called the “garlic press” funneling Arctic Ocean ice south where it melts.

A “Blue Ocean Event” where the Arctic Ocean is largely free of ice is not that far off anymore. That will cause extreme weather in the middle northern latitudes. Blue ocean absorbs sunlight, warming there by, white ice and snow reflect it, staying cool. Warm oceans evaporate providing moisture and energy to any storms that arise or reach there.
