The Arctic and the Antarctic are regions that have a lot of ice and acts as air conditioners for the Earth system. This year, Antarctic sea ice reached a record maximum extent while the Arctic reached a minimum extent in the top ten lowest since satellite records began. One reason we are seeing differences between the Arctic and the Antarctic is due to their different geographies. As for what's causing the sea increase in the Antarctic, scientists are also studying ocean temperatures, possible changes in wind direction and, overall, how the region is responding to changes in the climate. (FWIW 2015 Antarctic ice extent was slightly smaller, falling back to its 2008 extent)
C) These super chilled air masses then slide off the continental dome (elevation 8,000ft+) becoming the fabled Katabatic Winds which are also reaching record breaking speeds and low temperatures.
I couldn't find good YT description of Antarctic's Katabatic Winds, the principle remains the same. Keep in mind Antarctica is the highest continent on Earth averaging 8,200ft with it's highest mountain 16,050ft and a very long winter night. Compare that to Greenland's average of 2,135ft and highest peak of 12,120ft.

John Sonntag, the NASA Operation IceBridge navigator and unofficial team meteorologist, gives a fabulous presentation about the katabatic winds that affect Greenland on a regular basis.
Despite Antarctic Gains, Global Sea Ice Is Shrinking

“There hasn’t been one explanation yet that I’d say has become a consensus, where people say, ‘We’ve nailed it, this is why it’s happening,’” Parkinson said. “Our models are improving, but they’re far from perfect. One by one, scientists are figuring out that particular variables are more important than we thought years ago, and one by one those variables are getting incorporated into the models.”
The exact details? The exact details of what?
What about focusing on all you do know with certainty?
No question about the ozone hole and colder temps and more powerful winds!
No question about circumpolar currents getting disrupted by increasing warm water!
No question of warm global air temperatures leading to more moisture in atmosphere and more precipitation!
No question of Sea water freshening!
No question that we are witnessing increasingly monstrous amounts of tens and hundreds of thousands of year old glacial ice flowing out into the ocean.
What's this obsession with thinking every detail needs to be nailed down, out to three decimal points, before you feel comfortable making rational and logical connections and assertions to our leaders and public? It doesn't mean getting sloppy, it means refocusing your perspective to encompass and better explain the bigger story going on.
What's wrong with tying together the strands of information that we do understand with human near certainty? What about framing it in a way that paints a picture, rather than facts that flow in one ear and out the other?
