In 2014, NOAA blamed high sea ice on global warming. Now, the NSIDC accuses of recording low sea ice on global warming.
The sea ice in the world falls very low

Satellite data show that the world's frozen oceans help keep the earth cool and currently have less ice than previously recorded.
The sea ice around the Arctic and Antarctic is like a huge mirror, bringing most of the energy back into space, just like a huge mirror.
However, as the temperature increases, this bright layer shrinks, the dark ocean below absorbs more heat, further heating the earth.
This latest sea ice low seems to be driven by a combination of warm air, warm oceans and wind collapse.

“Every year, every data point we get shows This is not a temporary change, but a more permanentjust like we see in the Arctic,” Walter Meier, a senior research scientist at NSIDC, told BBC News.
“This suggests that Antarctic has entered a new regime with lower ice.“

Back in 2014, melted glaciers reduced the seawater to salt water and were accused of record Antarctic sea ice.
Antarctic winter sea ice range sets new records in 2014
Michon Scott reviewed by Ted Scambos
Release on October 7, 2014detail
…
Unreasonably wondering if the planet warms, Antarctic winter ice can make record highs. As the NSIDC release explains, the sea ice growth breakthrough in Antarctica may depend on stronger winds and slightly fresh sea surface water around the edge of the continental melting ice shelf.
…
The wind may not be alone to stimulate so much sea ice growth. The melted ice may have played a role. Most of the ice in Antarctica is on the ice caps covering the continent. The ice has been melting in recent decades. Along the coastline, ice shelves float on the sea surface, and most of the recent melt may be driven by warm water rising from the deep sea and contact with the bottom of the ice shelves.
How does the melting of land ice and the formation of sea ice? The resulting melt is fresher than sea water. When it is mixed with seawater, the melted water makes the nearby seawater slightly smaller and closer to freezing point than the one below. This less dense seawater spreads on the ocean surface around the continent, forming a stable surface pool near the freezing point and close to the ice it can freeze.
so It's counterintuitive, just like expanding the winter Antarctic sea ice may appear on warming planets, In fact, this may be a manifestation of recent warming. “The Arctic and Antarctic are both coping with climate change and have areas that are rapidly warming,” explains TED Scambos, chief scientist at NSIDC. “But Antarctic sea ice responds to wind changes and ocean changes in unexpected ways, we still have to do it,” explains. In an effort to fully understand it.”

Sea ice scientists should be clean and admit they don’t know which direction the sea ice will move next, rather than betting, blame any change on global warming.
At least in the last century, there was a lot of evidence for Antarctic sea ice.
In 2013, the April Fools' Day expedition's “Mosen Spirit” ship was trapped in sea ice while trying to relive a small part of the Mosen Antarctic adventure.
Antarctic sea ice is too bad, talk about relocating the Morson base.
What was Antarctic sea ice like in the Mosen era? Although many bad things happened on Mawson Expeditions (1911 and 1929) and his other visits to Antarctica, Mawson managed to reach Antarctica at least three times, unlike the fool ship.
Arctic sea ice has also proven highly variable over the years, with prolonged continuous melting and freezing, many of which occur before anthropogenic carbon dioxide may become an important factor.
What conclusions can we draw from all this?
Given the history of extreme natural mutations, it is obviously obvious that it is too early to declare a “new regime” of sea ice on the strength of a decade-old sea ice resort. Furthermore, I think the 2014 record-breaking global warming “interpretation” of Antarctic sea ice in 2014 shows that today, global warming is now driving the decline of sea ice is just speculation.
