This tweet by Tony seems to have sparked interest in building media green.
The text reads: “The Antarctic sea ice range is 17% higher than in 1979. The ice does not lie, but climate scientists.”
An NSIDC spokesperson told Reuters via email that the Antarctic sea ice range on December 24, 1979 was 7.38 million square kilometers, and on December 24, 2024, it was 8.28 million square kilometers. This increased by 12.2%.

However, NSIDC data also suggests that for most of 1979, new Tab Sea Ice was opened for most of 1979 compared to the days in 2024. …
“It’s kind of like saying that because the sports team won the first game of the year in 2025, but lost the first game of the year in 2020, they got better, even if they were the lowest point in the league in 2025. In the 2020 league,” she said.

Antarctic sea ice changes are particularly special and violate attempts to link its long-term trends to climate change, an NSIDC spokesman said.
“In the absence of clear climate causes, many scientists view ocean changes as a cause.”
However, uncertainty about the relationship between Antarctic sea ice and global temperatures did not invalidate the evidence of global climate change.
“Even if sea ice returns in Antarctica, it won't refute other indicators of climate change. Warm oceans, melting glaciers, and sharp losses from Arctic sea ice are just numerous signs of a warm planet,” Screen said.
Tony Heller responded to the Reuters “fact check”.
Total BS @reuters . Ten years ago, Antarctic sea ice was at record highs, the same government #ClimatesCam Professionals try to blame global warming. https://t.co/a3kthcujzo https://t.co/axwl4drhyu pic.twitter.com/zhulqibuc7
When they mentioned uncertainty and sea ice variability, Reuters forgot that the 2014 record Antarctic sea ice, mentioned in 2014, was blamed for global warming.
Antarctic winter sea ice range sets new records in 2014
Michon Scott reviewed by Ted Scambos Release on October 7, 2014

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, Actually it may be The 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.”
“It may actually be” didn't fill me with certainty.
If melting land ice in the Antarctic peaks sea ice, which is because melted freshwater ice reduces the salinity of adjacent seawater, then why is the Arctic ice peaking in the Arctic? Or does the melted ice only work at the southern latitude? Talk about the big gains in the southern ocean, but should the concentration of land ice in the nearby area melt into the inland Arctic oceans that will cause more sea ice formation?
If sea ice understands global warming so bad and variable, why do we have to demand for years that global out-of-control global warming will flood all coastal cities and melt polar ice caps?

The interface between science and politics
B Stauffer said science cannot stop global climate change, so science should support sustainability, but if science can point to means to slow down global change, it would suggest that something can be done and evoke political decisions.
J Jouzel said the facts will come from the use of the model and its validation, and WCRP (Clivar) has gained more interest in Palaeo-Data. Communication between scientists and politicians is becoming increasingly important, and the scientific population must be large enough to see it. D Raynaud commented that Stocker's changes in total emissions and thermal cycles in 1997 were important to conferences such as Kyoto. K Hutter added Politicians accuse scientists of their high noise ratio. Scientists must make sure they give stronger signals. The time frames of science and politics are very different. Politicians need instant information, but scientific results take a long time
Ghazi noted that once politicians want to do research, funds can be set. We need to let them know that we don’t understand the climate system. Kyoto is a compromise, and the level of pollution accepted by the EC is not accepted by all members. At the next meeting in Buenos Aires in November 1998, we had to learn how to get close to the United States. The United States wants to buy 30% of Russia's unrealized emissions. Such emissions trading is unacceptable. However, the United States believes that if the EC trades internally, it can do the same, but the EC will reach 6-8 emissions.

From Climategate Email 0700.txt
The pressure from politicians controlling research funding on scientists to provide a “stronger signal” has caused obvious concerns—though fairly, in the email, scientists are determined to try to educate politicians about how science works.
One thing seems to be clear. No matter what you read, hear or see in the media, no one really understands the global climate system, especially when it comes to the behavior of polar sea ice.
