Why is Antarctic sea ice at record levels despite global warming?

That is a bunch of coocoo puffs.
A wise person would quit trying to get serious and factual scientific information out of a religious text.

That would be because other areas are the ones heating up. In the south it is around Australia, in the north it is the west coast of North America that is warming up but the east is cooling off more so snow will be on the ground longer in most locations.

The planets do not circle around the sun haphazardly, but they follow the spinning movement of the sun and electromagnetic field which is about the equatorial plane of the sun.
In other words they do not circle around the plane of the two poles of the sun.
They circle in the equatorial plane, but not exactly: they orbit in a plane just below the equatorial plane of the sun.

This image may give a better explanation of the idea


The sun is the upper disc and the persons resemble the planets and they circle around the sun in a plane lower than the plane of the disc or the sun.
And for this reason the head or the north pole receives more heat than the foot of the person or the south pole.

Antarctic sea ice is currently above average, but no where near record extent. Not sure why the spikes exist.

Orbit is a better word because their orbits are not circular.

Because gravity pulls them down a little bit, right?

Except for when ice travelled from north to south during a couple ice ages, right?

Just about everyone and their dog talks about sea ice and almost everyone and their dog ignores sheet/land ice.
Is Antarctica losing or gaining ice?

It did achieve record extent in 2014 but they only have records back to 1979.

Well now, there are two serious problems with that argument. First, an argument using a regional phenomenon to disprove a global trend is dead in the water. Second, the Antarctic could warm quite a lot and still be well below zero on average. One consequence of warming is increased precipitation, and increased precipitation in the Antarctic means the ice cover will grow.

Why has this global trend been so difficult to recognize in so many regions such that legislation requiring global warming deniers to be flogged is before several nations lawmakers today? Why is something so apparent to the throngs of lunatics who believe the Sun may be regulated with increased taxation so invisable to better thinkers? Heat leads CO2 in every case. You should surrender your carbon for capture.

The spikes indicate a loose fanbelt.

The sea ice extent in the Antarctic could have something to do with the conveyer process that starts there. As the sea water starts to freeze in winter, ice starts to crystalize and forms long "tendrils" below the surface. Now, I'm not sure how the rest of this works but as the tendrils form and grow, briny water heavy with salt starts to fall to the depths, eventually forming a vast waterfall of extremely cold, salty water that's something like the equivalent of 2000 Niagara Falls. This massive loss of salt from the surface waters allows the sea around Antarctica to freeze more easily and more completely.


Add to that the fact the southern ocean is rarely ever still. It is constantly being stirred around Antarctica by winds which makes it more difficult to heat up as the action of the water helps dispel the heat back into the air. Thus, in combination with the loss of salinity in winter makes it fairly reasonable that the Antarctic ice would defy the climate models.

“It’s not expected,” says Professor John Turner, a climate expert at the British Antarctic Survey. “The world’s best 50 models were run and 95% of them have Antarctic sea ice decreasing over the past 30 years.”
GIGO. Why would it be a surprise? Were they really expecting accuracy when the computer modelers toss out data that's inconvenient to the narrative?
