Sea ice around Antarctica has “slowly increased” since the start of continuous satellite recordings in 1979 with any changes caused by natural climate variation. In a paper published earlier this year, four environmental scientists further state that any sign that humans are responsible for any change is “inconclusive”. Not of course for mainstream media that have been crying wolf about the sea ice in Antarctica for decades to promote the Net Zero fantasy. Last year there was a reduced level of winter sea ice and this caused the Financial Times Science Editor Clive Cookson to exclaim that the entire area “faces a catastrophic cascade of extreme environmental events… that will affect climate around the world”.
Over the satellite record, the scientists note there was a “prolonged and gradual” expansion of sea ice to around 2014 followed by a short period of sudden decline from 2014-19. Growth was then resumed, although there was a temporary downturn around 2022. These variations, which can also be observed before 1979, were caused by a number of natural atmospheric and oceanic factors. All of this is known of course, with the EU weather service Copernicus admitting recently that sea ice extent as a whole “shows large year-to-year variability and no clear long-term trend since 1979”. At the other end of the Earth, Copernicus correctly states that the cyclical decline in Arctic sea ice “has levelled off since 2007”.
It must all be very bewildering for narrative-following journalists. Confusion no doubt reigned supreme in their unquestioning ranks when they chanced upon the comments last year of Dr. Walter Meier of the U.S.-based National Snow and Ice Data Centre. He was in full activist mode when he claimed the 2023 winter sea ice dip was “so far outside anything we’ve seen, it’s almost mind blowing”. But not perhaps as confused as Dr. Meier himself who 10 years earlier was part of a scientific team that cracked open the secrets of early Nimbus photographic data. These revealed significant Antarctica sea ice variability in the 1960s, including a high in 1964, not seen again until 2014, and a low in 1966, similar to the recent dip. At the time, Dr. Meier commented that extreme ice highs and lows “are not that unusual”.
During the Great 2023 Antarctica Ice Scare, the BBC said that it showed a worrying new benchmark for the region “that once seemed resistant to global warming”. Still does, those striving for accuracy might note. Antarctica has hardly warmed in the last 70 years.
One by one the appalling scares that have been used by Net Zero fanatics to promote mass climate psychosis in human populations are being exposed as wishful junk thinking. Over the last few decades, alarmists have taken their cue from the ozone hole scare that started in 1974. At this time, two scientists claimed that the widespread industrial use of chlorofluorocarbons (CFCs) was destroying the protective ozone layer in the atmosphere. Subsequently, an annual appearance of an ozone hole was discovered over Antarctica and CFCs were banned by international agreement in 1995. The two scientists received the Nobel prize for their work, and activists claimed it was all a great triumph showing what could be achieved when humans acted in concert to protect the planet. The Nobels were accepted and the activists moved onto other scares and proposed bans. What happened to the ozone hole, you ask? Well that kept on expanding and contracting as it has always done, and this year the hole is as large as it has been for the last 30 years. Whisper it quietly – natural variation seems to be at work here.
As readers will no doubt be aware, there is gathering excitement about the prospect of another ‘hottest year evah’ for 2024. There has been a little extra warmth recently following a near nine-year temperature pause with scientists looking at a number of natural variations seen often in the past.
Hottest year claims are produced from woefully incomplete temperature records that are barely 100 years old. In the case of sea temperatures, accurate and complete global records stretch back less than 20 years. The temperature data itself, as we have seen in many Daily Sceptic articles, have been homogenised/reanalysed/invented/adjusted on an almost constant basis. Most individual temperature recordings around the world have been corrupted by urban heat, while in the U.K. the Met Office seems inordinately proud of a national high set in 2022 as three Typhoon jets were landing at a RAF airbase. If we consider the proxy record, it seems likely that temperatures were as high in Roman and medieval times, while 8,000 years ago the great northern ice sheets started to melt helped by temperatures at least 3°C higher than those experienced today. Again it is difficult not to conclude that natural variation plays the dominant role in controlling the climate thermostat.
Thoughts and prayers are also the order of the day for those who set great store in all the coral disappearing. Three years of record growth on the huge Great Barrier Reef put an end to that headliner. Polar bears are just as bad and keep breeding to top up new Arctic highs. Satellites keep discovering vast colonies of penguins in Antarctica, and mainstream media seem shocked into complete silence to report that the eyes in the sky have detected a vast recent plant greening of the Earth. There is a growing trend to debunk any ‘extreme’ weather claim – the great citizen journalist Paul Homewood even writes a book about the BBC’s more egregious climate howlers, every year no less, such is the volume to process.
The Net Zero project is starting to crumble around the world as citizens make their feelings known with votes, and sometimes with rocks. Nobody can or wants to live in a world without hydrocarbons. Crucial to this trend is an emerging understanding that the scientific process when it comes to climate has been trashed for decades and replaced with an increasingly laughable junk ‘settled’ science narrative.

Antarctica Sea Ice Has “Slowly Increased” Since 1979, Science Paper Finds
______________________________________________________________
The Climate Cult will just lie about it. Just take a look at how their graphics have changed for the northern hemisphere sea ice in all their IPCC reports so far: FAR,SAR,Tar,AR4, AR5 & AR6 The latest is really interesting:
Send Jerry Brown there on a one-way trip.
Especially when you are living in Antarctica doing research.
In a paper published earlier this year, four environmental scientists further state that any sign that humans are responsible for any change is “inconclusive”.
Not really. Only with the use of their referenced tool, LFCA. AFAIK, they didn’t comment one way or the other on your more general claim.
In summary, LFCA can identify modes of sea ice variability
associated with both the gradual long-term increase
and the sudden decrease in observed Antarctic sea ice. While
LFCA has been used in other studies to isolate the forced
response (Wills et al., 2020; Dörr et al., 2023), the large
interannual-to-decadal variability in Antarctic sea ice makes
this analysis inconclusive about the sign or pattern of Antarctic
sea ice response to anthropogenic forcing over the historical
period.
Did you hear the one about Alimonti???
Gosh you people are bad losers.
So, no actual disputation of my post? And tell ’em what they “lost” Monty….
Your post was blather.
And peer review in terms of negative votes agrees. And I don’t downvote as the system can show
You can believe there is a climate crisis if you choose, but like any other religion it’s utter bolleaux – unreal and you have only a model.
bigoilbob, thanks for my new word of the day: disputation – debate or argument. That’s the first useful….OK, I’ll stop.
You post says absolutely nothing. It is a copy-paste of text you obviously have zero understanding of.
Is there s.th. to dispute ? Can’t find it.
There is no evidence that humans have any effect on Antarctic sea ice whatsoever. !
Confusion will be their epitaph.

Very cool.
Very nice Chris. I am sick and tired of my government lying to me 24/7. Worse yet using my money to do it. I primarily blame bureaucrats and administrators.
The CIA explained this to Congress, way back in the 1960s I think.
Their best weapon against foreign enemies (their job purpose, after all), is misdirection and misinformation. Now, how could they expect enemies to believe any of it if they told their own citizens the real truth?
Warmunists made a fundamental (and now irretrievable) mistake decades ago. To demonize CO2, they had to do two things.
So now their ‘scientific’ credibility is irretrievably damaged.
“Not of course for mainstream media that have been crying wolf”
They wouldn’t apply the heavy spin that Morrison does. The fact is that the Ice has shrunk. From the paper:
Now, evidence of human causation ??
Evidence that the drop in Antarctic sea ice is a problem ??
You need to explain, with evidence, how humans caused the steady increase up to 2014…
… then the sudden drop to 2017, then the drop in 2023.
(Sigh) . . . Nick, I guess it might as well be me that has to point out to you that the data points on the plot that you posted from D.B. Bonan et al—by the way with a line improperly connecting the data points as if they represented a continuous function— is for annual sea-ice area anomaly, NOT the progression of total areal coverage. One would have to integrate the annual anomalies from 1979 to 2022 to determine if the sea-ice area has increased or decreased over the noted interval.
Just eyeballing the integration, it appears to me to be a net increase.
“One would have to integrate the annual anomalies from 1979 to 2022 to determine if the sea-ice area has increased or decreased of over the noted interval.”
Quite wrong. The anomaly is just the difference between a daily value and the long term average for that day. For the annual anomaly average, that just means subtracting a constant, all years.
Here is the NSIDC plot, in absolute area. 2014 is the mauve at the top. Orange is 2022, their minimum. 2023 (brown dash) was much lower again, and 2024 so far (sky blue) a little higher, but lower than 2022.
(Double sigh) . . . Nick, did you read—more importantly understand— the label on the y-axis of the D.B. Bonan et al. graph that you presented previously? It reads “Annual Antarctic sea-ice area anomaly (10^6 km^2)“. Notice the word “annual”?
And did you notice the data points are given for each year, NOT each day.
Your back-to-back sentences:
“The anomaly is just the difference between a daily value and the long term average for that day. For the annual anomaly average, that just means subtracting a constant, all years.”
are thus non-sensical because in the fist sentence you imply subtracting a given day-of-the-year’s long term average from that day’s (measured) value, but in the second sentence you refer to subsequently averaging all such daily anomalies over a given year and subtracting a “constant value”. Looks like double subtraction to me: “long term average for each day” followed by “a constant”.
Also, your latest presentation of the NSIDC plot is a weak attempt at deflection and meaningless in context since it does not reach back to 1979, the starting year-of-comparison stated in the headline of the above article and in its very first sentence, and is irrelevant to my response to you regarding what the D.B. Bonan et al. graph both shows and fails to show, again starting in 1979.
The NSIDC data does go back to 1979, although there was very little data that year. My plot showed 1980 in dark orange; unfortunately the bottom of the key was cropped (fixed).
As I said, with all data present, the only difference between the average and the anomaly average is a constant (over all years). You can see this below where I have plotted the annual average in absolute terms, since 1990. There is missing data before 1990 which makes anomalies necessary. My newer plot also shows the even greater shrinkage of the ice since Homan’s plot.
Totally irrelevant and meaningless.
You have shown that you know there is ZERO human causation..
You newer plot is a classic piece of disingenuous propaganda.
As we totally expect from you.
Let’s look at reality… Yes, a hint of a drop from 2014-2017, then another in 2023…
.. but absolutely nothing that could be chalked down to any human causation.
The more you ignore that fact.. the more stupid you look !
Here is my graph of the annual averages. I started in 1990 because earlier years had missing data, making anomalies essential. It includes 2023 and 2024, and shows the continued rapid shrinkage of the ice:
Pitifully unable to produce any evidence of human causation.
Or evidence that the drop in Antarctic sea ice is in any way a problem.
You need to explain, with evidence, how humans caused the steady increase up to 2014…
… then the sudden drop to 2017, then the drop in 2023.
Your comment is irrelevant to the topic.
Try showing it from a zero on the Y axis. Then show it with actual annual variations, not just one point each year.
Your dramatic graph will disappear in the annual variations alone.
There is signs of a slight NATURALLY caused drop from 2014-2017 ..
and a drop in 2023..
But as Nick has shown, these are not caused by anything humans have done.
” Then show it with actual annual variations”
I actually do that, in a maintained interactive plot on my website. It shows daily values on a polar plot, with area as the radial value (shown on the “x axis”, zero at the origin), and angle as day of year. You can see the remarkable excursions of 2023 and 2024.
TOTAL FAIL to show any human causation. !
Notice how COWARDLY Nick is in addressing this.
Nick’s minder sharpened his crayons.. whoopie-do !
Graph shows just how stable the Antarctic Sea Ice Extent was until the last 2 years, which is highly likely to be to do with the HT volcano+ El Nino event
There is absolutely no evidence of any human causation, is there Nick.
And the answer above yours shows the data in real perspective, not some artisticly skewed format. Reality trumps hyperbole, I’m afraid.
It is very telling that you are forced to use such a complex format in order to pretend something untoward is occurring. What is wrong with the extremely simple and easy to understand format above? Just not scary enough?
“What is wrong with the extremely simple and easy to understand format above?”
I showed that first, and you found something you didn’t like (surprise!).
But polar plots are not complex, and are commonly used for periodic data like these. It’s like a clock face. It shows the whole history as a continuous line (with color changes). It’s just more revealing. If you find that scary, well, perhaps you should. Anyway, it’s how it is.
“But polar plots are not complex”
… but in this case, it is TOTALLY MEANINGLESS.
It reveals absolutely NOTHING about any human causation.
You need to explain, with evidence, how humans caused the steady increase up to 2014…
… then the sudden drop to 2017, then the drop in 2023.
Otherwise your graph is totally IRRELEVANT.
This one is much easier to read..
… sorry if you need lots of pretty colours to gain an understanding.. !
Note yet again the increase from 1990 to 2014
Then two step-like drops.
Please explain how humans caused this.
Well . It seems that Nick agrees with the paper where it says…
Not just “inconclusive”, but totally non-existent.
Nick has, yet again, shown that his comments are just mindless attempts at petty distractions and nit-picking.
His comments are of ZERO scientific worth.
“the continued rapid shrinkage of the ice”
WRONG..
there has been a general INCREASE in sea ice with two drops in extent, that happen to coincide with two major El Nino events.
Even between those two events, from 2017 to 2022, sea ice increased.
There is no evidence of any human causation..
You know that… That is why you are slithering around like a little worm.
I declare from the graph supplied by Mr. Stokes that the 34 year increase in ice in Antarctica was caused by human emissions of CO2.
The question re the why is there a relatively steady increase up to 2014 is a pretty reasonable one though.
Yes, that is what the paper is about. They have answers.
Only one way to settle this, Nick.
Chris Turney will have to take another ship full of climate cranks down to Antarctica to sample the melted ice sheets.
They have absolutely no evidence of human causation.
Neither have you. !
My bad for being a bit lazy. I have no expertise in the hydrodynamics but it seems to me that the conclusions are a bit speculative w.r.t. mechanistic answers. However, it bothers me more that the time scale is only 40 years or so.
It’s the period of satellite data – and in fact data before 1990 is patchy.
It is Chris Morrison and WUWT who are pushing this paper – not me. I see what others see – ice is at levels by far the lowest in that period. That is what we know.
NO… you see NOTHING except the effect of the 2023 El Nino and HT volcano.
You have ZERO evidence of any human causation.
That means that you accept that the drop is TOTALLY NATURAL . !
All your yapping is irrelevant.
You still haven’t explained the INCREASE until 2014,
…. then the two dips that just happen to coincide with two major El Nino events.
You still haven’t even attempted to show anything other than a totally natural variability.
Pathetic. !
and in fact data before 1990 is patchy.
Which makes any measured trend meaningless. 40 years is only 0.34% of the holocene.
1979 to 2022 (the interval of the D.B. Bonan et al. graph presented above by Nick Stokes is a period of 43 years, inclusive.
Sea ice, like every other weather related statistic, varies year to year. Ever heard of statistics? And curve fitting? And standard deviations?
No evidence of any human causation, is there Nick.
Graph with 12 month trailing average added.
Show me the human causation, with evidence !!
(Note: before 1990 there is too much inconsistently missing data, and also a 2 day time period instead of daily, I couldn’t be bothered sorting it out)
You don’t do math, or curve fitting, or figuring out standard deviations?
C’mon how bout an actual calculation?
Human causation or not, I disagree with the premise of this article, starting in 2016 Antarctic Sea Ice began a dramatic decline and appears to be in conjunction with a warming trend in the Southern Ocean, and cannot be blamed on solar activity.
Antarctic Sea Ice Anomaly
Southern SST Mid lats
Sunspot Number
Oh, nit-picking Nick!
Please show it in proper context. I know you hate that, but do try.
When shown as a total amount of sea ice, including annual variations, it is very easy to see that these figures in complete isolation without any context of the sheer amount of total sea ice in the Antarctic are completely irrelevant.
See polar graph above
Meaningless squiggles.. the Nick finger-painting way.
And still he runs away from showing any human causation.
As I wrote above, it’s extremely telling how you are forced to resort to such an obscure format to try to pretend something scary is occurring. The simple format exposes the tangled web you attempt to weave.
And he still is totally incapable of showing any human causation.
Not even making an attempt.. What a COWARD.
All this hysteria and yet nobody recognizes that if CO2 is responsible, and there is little proof of that, absolutely nothing can be done about it unless India and China join in to implement some as yet unknown CO2-free technologies that can replace all that fossil fuels do for us. Are Biden, Starmer and all the other politicians ignorant of those unassailable facts? I don’t think so. They just ignore them.to keep the cash and power flowing.
Hah! Even if India and China (indeed every nation on Earth) were to slash their CO2 emissions by 50% or more, which ain’t gonna happen, it wouldn’t make a squat’s difference in the variation of CO2 in the atmosphere.
Hundreds-of-thousands to hundreds-of-millions of years ago Earth had variations in atmospheric CO2 levels ranging from a low to about 180 ppm to a a high of about 2500 ppm . . . and humans had nothing to do with it! Even today, our contributions to total atmospheric CO2 concentration are essentially insignificant, maybe as much as 5%.
Is this news, perhaps, an indication that the “warming” isn’t so “global” after all?
Alert notice to the UN and its IPCC.
Thoughts and prayers are also the order of the day for those who set great store in all the coral disappearing.
Scientists say biggest coral in the world discovered in the Pacific
Amen
And what’s relevant to note is that Antarctice Ice volumes absolutely dwarf those of the Arctic in the Northern Hemisphere. You can have significant reductions in Arctic Sea Ice without total planetary ice volumes being affected that much.
Where do you get that idea from? Over the last several years the Antarctic sea ice minimum area has been ~1million km^2 compared with the Arctic minimum of ~4 million km^2.
So? Why all the persistent nonsense about human triggered global warming?
