The mainstream are heat-chasers. They report only on stories that fit the AGW Party agenda. This cherry-picking leads to a painfully misinformed public when it comes to the climate–which is exactly where they want us.
It usually stands, however, that if the MSM goes silent on a particular locale then it’s probably because that particular locale isn’t ‘behaving’ as they would like.
ase in point today: we have the Arctic and Greenland refusing to play ball.
Earth’s most-northern reaches are actually experiencing persistent and long-lasting COOLING, which is far more telling than a brief burst of heat in, for example, Western Europe, which, 1) is forecast to be over before it’s even really begun, and 2) can be tied to entirely natural forcings–namely low solar activity and a violently ‘buckling’ jet stream flow (more on that below).
The globe hasn’t been warming and the Arctic hasn’t been melting much for almost a decade now.
Recall the climate crisis loonies warned us some 20 years ago the Arctic sea ice would disappear by the summer of 2014. Well it’s still very much there, as Joe Bastardi reminds us at his most recent Saturday Summary:

No warming in 8 years
Moreover, UAH global mean temperature anomaly hasn’t risen in eight years as well, Hat-tip Snowfan here:

Despite rhetoric to the contrary, there is still plenty of sea ice over Arctic regions this summer, supplying feeding platforms for polar bears, ice-dependent seals, and walrus cows nursing their young calves. Forget about whether the numbers are below or above some short-term average, there is no catastrophe in the making for marine mammals in the Arctic at this time.
Remember, by early summer, young seals have left the surface of the ice and are in the water feeding; predator-savvy adults and subadults are hauled out on broken chunks of ice moulting their hair-coat. They may look like sitting ducks but polar bears have a hard time catching them because the seals are vigilant and have many escape routes available (due to all the open water). Most polar bears in Hudson Bay are still on the ice (you’ll see why below): the live cams near Churchill set up to watch polar bears are presently showing images of ravens with sea ice in the background, not bears.
This post is predominantly sea ice charts for mid-July, what we in the science field call observational evidence, aka ‘facts’. Keep in mind that satellites used to produce these images have an especially hard time distinguishing ice topped with melt water from open water, which means much more ice useful to these marine mammals is almost certainly present than is shown in the charts (as much as 20% more in some regions).
A new study (Gupta et al., 2022) indicates that from 2000-2019 73% of the 15 sites considered have been cooling and 67% have experienced a lengthening of sea ice duration.
Canada’s Hudson Bay extends into the Arctic Ocean and its coasts are teeming with polar bears.
Scientists report 11 of 15 Hudson Bay sites have been cooling since 2000. The average cooling for these 11 sites is -0.34°C per decade.
The World Economic Forum and the globalist movement it helps lead have used the “climate crisis” and the COVID-19 pandemic as pretexts for measures to redistribute the wealth of nations.
But this week, as WEF convenes is annual conference in Davos, Switzerland, the Arctic sea ice expanse so far this month is at a 30-year high, according to data from intergovernmental European Organization for the Exploitation of Meteorological Satellites, points out climate-change skeptic Tony Heller.
EUMETSAT, as the organization is known, was created through an international convention signed by 30 European nations.
The extent of Arctic ice during the warmer months long has been a metric for climate-change alarmists. In 2007, Al Gore began warning the world that scientists were predicting that by 2013, the Arctic would be ice-free during the summer.
There’s a few things to note at first glance. The ice floe continued to decrease in thickness into November. It’s thickness then started to increase, but is currently still less than 2 meters. Also the snow depth has gradually been increasing, and (apart from some data glitches!) is now ~38 cm. Finally, for the moment at least, the ice surface temperature has been slowly warming since mid February and is now ~-11 °C.
While sea ice has been declining off the Greenland Sea (east of the island), the Chucki Sea (eastern Siberia) shows a very different trend in sea ice extent over the past year. Such deviations have occurred repeatedly since the year 2000.
Overall, the 2021 extent was very close to the 1991-2020 mean and well above the lowest value in 2012 and also above what was recorded in the year 2020
The average sea ice cover at the end of March is the metric used to compare ‘winter’ ice to previous years or decades, not the single-day date of ‘most’ ice. This year, March ended with 14.6 mkm2 of sea ice, most of which (but not all) is critical polar bear habitat. Ice charts showing this are below.
But note that ice over Hudson Bay, which is an almost-enclosed sea used by thousands of polar bears at this time of year, tends to continue to thicken from March into May: these two charts for 2020 show medium green becoming dark green, indicating ice >1.2 m thick, even as some areas of open water appear.
In a recent paper, scientists expressed their surprise that the Arctic had started warming already back in the early 20th century, 100 years ago. This, along with the obligatory CO2 climate warming lip service, is described in a Cambridge University press release.
Natural oceanic currents
The Arctic Ocean has been getting warmer since the beginning of the 20th century—decades earlier than records suggest—due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean.
An international group of researchers reconstructed the recent history of oceanwarming at the gateway to the Arctic Ocean in a region called the Fram Strait, between Greenland and Svalbard.
…
…
The researchers used geochemical and ecological data from ocean sediments to reconstruct the change in water column properties over the past 800 years. They precisely dated sediments using a combination of methods and looked for diagnostic signs of Atlantification, like change in temperature and salinity.
“When we looked at the whole 800-year timescale, our temperature and salinity records look pretty constant,” said co-lead author Dr. Tesi Tommaso from the Institute of Polar Sciences of the National Research Council in Bologna. “But all of a sudden at the start of the 20th century, you get this marked change in temperature and salinity—it really sticks out.”
“The reason for this rapid Atlantification of at the gate of the Arctic Ocean is intriguing,” said Muschitiello. “We compared our results with the ocean circulation at lower latitudes and found there is a strong correlation with the slowdown of dense water formation in the Labrador Sea. In a future warming scenario, the deep circulation in this subpolar region is expected to further decrease because of the thawing of the Greenland ice sheet. Our results imply that we might expect further Arctic Atlantification in the future because of climate change.”
The researchers say that their results also expose a possible flaw in climate models, because they do not reproduce this early Atlantification at the beginning of the last century.
Perhaps the last bear leaving Cape Churchill for the sea ice, 4 December 2021.
Moreover, considering that 2021 fall ice formation for the Arctic in general is well ahead of 2016 (and every year since, except 2018), it’s hard to see why human-caused global warming caused by ever-increasing CO2 emissions explains the slow freeze-up of Hudson Bay. Timing of Hudson Bay freeze-up has always been highly variable from one year to the next (Castro de la Guardia et al. 2017: Fig. 3, copied below). The average freeze-up date in the 1980s was 16 November ± 5 days, while from 2005-2015 this had shifted about a week to 24 November ± 8 days (Castro de la Guardia et al. 2017:230). This year freeze-up was later than usual but last year and the three years before that the ice froze as early as it did in the 1980s. Cue the zombie apocalypse.

A new study throws doubt on the theory that Arctic warming is man made.
The Arctic Ocean has been warming since the onset of the 20th century, decades earlier than instrument observations would suggest, according to new research.
The study, published Wednesday in the journal Science Advances, found that the expansion of warm Atlantic Ocean water flowing into the Arctic, a phenomenon known as “Atlantification,” has caused Arctic water temperature in the region studied to increase by around 2 degrees Celsius since 1900.
Francesco Muschitiello, an author on the study and assistant professor of geography at the University of Cambridge, said the findings were worrisome because the early warming suggests there might be a flaw in the models scientists use to predict how the climate will change.
Christmas is coming. Santa’s secret summer swimming pool has frozen over. The time has come for a new monthly Arctic update.
The JAXA/ADS/ViSHOP web site is undergoing maintenance for a week, so let’s start the festive season with a look at high resolution AMSR2 area and extent:
On the Finnmark plateau, between Kautokeino and Karasjok, temperatures dropped down to -35°C on Sunday. The forecast for the coming week shows a temperature anomaly for the last days of November of 10°C below the reference period 1961-1990, the Swedish Meteorological and Hydrological Institute informs.
Coldest out is Nikkaluokta near Gällivare in Norrbotten with -36°C.
In times of climate change, the current freeze comes in sharp contrast to last fall, when meteorologists reported about the hottest October and early November ever measured, with an average of 6,7°C above normal across the Arctic.
Cold weather even sweeps the coast of northernmost Norway where the Arctic waters are kept ice-free by the warm Gulf Stream. In Kirkenes, on the border to Russia, the thermometer read -25°C on Saturday outside the Barents Observer’s office.
…
On the Kola Peninsula, Sunday November 28 came with temperatures from -18°C to -30°C the news online Severpost reported.
Further east in the Russian Arctic, quickly accumulating sea-ice on the Northern Sea Route has created a critical situation as a number of ships have been trapped in thick sea-ice for several weeks.
Data sources like the National Snow and Ice Data Center show global sea ice has been” drastically decreasing for a long time” and so we need to panic and overhaul the entire carbon economy. We hear this daily in the media.
Surprising global sea ice area findings
But Zoe has analyzed what she characterizes as a “very legitimate source” of data from NASA, (here, or here). And according to her findings, the data from these sources suggest global sea ice loss is not as dramatic as some institutes would like us to believe it is. In fact there ‘s been a gain!
Zoe plotted the data going back 40 years, from 1982 to 2021, the “Global Sea Ice Area Fraction”, which “is a proportion of the entire Earth’s surface that is ice over water.”
…
…
“As you can see, about 3.6% (on average) of our planet’s area is covered in ice over water,” reports Zoe. “In the last 40 years, ice over water has INCREASED, and not decreased, as popularly claimed.”
According to Zoe, the observed increase is equivalent to ~30,600 km², or “roughly the size of Belgium”.
Two icebreakers are on the way to rescue ice-locked ships on Northern Sea Route (snip)
District authorities in the Russian Far East have decided to commission two icebreakers to aid the vessels currently ice-locked in the East Siberian Sea. (snip)
[T]he South Pole also just witnessed a historically cold winter. As reported last month: “Between the months of April and September, the South Pole averaged a temperature of -61.1C (-78F). Simply put, this was the region’s coldest 6-month spell ever recorded, and it comfortably usurped the previous coldest ‘coreless winter‘ on record: the -60.6C (-77F) from 1976 (solar minimum of weak cycle 20).”
In fact, it turns out that, according to a study released a week ago:
PALEOCLIMATE DATA INDICATE THERE WAS LESS ARCTIC SEA ICE DURING THE PRE-INDUSTRIAL PERIOD THAN IN MODERN TIMES, OR WHEN CO2 CONCENTRATIONS WERE 100 PPM LOWER THAN TODAY (280 VS. 380 PPM).
Scientists (Diamond et al., 2021) assert that during the 18th and 19th centuries Arctic sea ice extent minimum (September) values averaged 5.54 million km².
Arctic Sea Ice Extent has been holding exceptionally well during the 2021 summer melt season.
Throughout August, higher volumes than usual have survived due to cold conditions and favorable wind patterns.
As a result, Arctic Sea Ice Extent is now the highest in 8 years, and, if this year’s trajectory continues for another week or two (which is expected), 2021 will achieve the ‘healthiest’ extent of the past 15 years (since 2006).
Only 2014, 2013, and 2009 remain in its way–though the gap is narrowing, fast:
This year’s Arctic sea ice minimum reaches third highest level in a decade, latest data show.
Die kalte Sonne here presents its latest climate video. The first part looks at this year’s Arctic sea ice melt season. Now that it’s September, sea ice extent has just about reached its minimum for the year and soon the annual refreeze will begin.
We recall that years ago alarmist scientists and wacko activists, like al Gore, predicted an ice free Arctic by now. Today we look at the most recent data and we see that we are a very long way from that point.
Very slow August melt this year
What follows is the chart from the National Snow and Ice Data Center (NSIDC):
by V. Jayaraj, Aug 2, 2021 in ClimateChangeDispatch
Every year, climate-change enthusiasts tell us the earth is getting hotter. Phys.org warned the world, “New ‘hottest year on record’ likely to occur in the next five years.”
C2ES informed readers, “It’s certain: The Earth is getting warmer, and human activity is largely to blame.” Bulletin of the Atomic Scientists’ headline read, “Broken record: The planet is getting hotter. And hotter. And hotter.”
But are we really observing record hot years consecutively?
While global warming is real and has been happening since the end of the Little Ice Age in the 18th century, the claims surrounding unprecedented temperatures are, at best, highly dubious.
Reality and some climate change claims differ as much as day and night. Here are two examples.
Strange Things: Readjusted Data Points
A few official agencies across the globe are widely considered “leaders” or “authoritative” in disseminating climate data.
Among them is the Met Office in the UK and top U.S. state agencies like the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA).
However, these agencies have used their near-invincible status to adjust climate data points as they please, often resulting in an exaggerated warming trend.
NASA carried out the supposed downward shifting of data points so that the temperature levels for 2020 (which were about the same as 2016) would now appear more extreme. Higgs revealed the downward shifting on Researchgate.
Why did NASA adjust the 2016 data point to make it appear that 2020 beat it by a larger margin than originally appeared? You decide.
Growth of Glaciers: Greenland Registers Historic Increase in Surface Mass Balance for July 2021
Greenland ice has been a topic of discussion ever since climate change became a headline item in news circles. The reduction of ice mass is often projected as proof of global warming.
by P. Voosen, May 13, 2021 in ClimagteChangeDispatch
Every time severe winter weather strikes the United States or Europe, reporters are fond of saying that global warming may be to blame.
The paradox goes like this: As Arctic sea ice melts and the polar atmosphere warms, the swirling winds that confine cold Arctic air weaken, letting it spill farther south.
But this idea, popularized a decade ago [and was the outlandish plotline in The Day After Tomorrow, pictured], has long faced skepticism from many atmospheric scientists, who found the proposed linkage unconvincing and saw little evidence of it in simulations of the climate.
Now, the most comprehensive modeling investigation into this link has delivered the heaviest blow yet: Even after the massive sea ice loss expected by midcentury, the polar jet stream will only weaken by tiny amounts—at most only 10% of its natural swings.
And in today’s world, the influence of ice loss on winter weather is negligible, says James Screen, a climate scientist at the University of Exeter and co-leader of the investigation, which presented its results last monthat the annual meeting of the European Geosciences Union.
Back in 2017, we famously had National Geographic falsely blaming a starving polar bear on climate change but since then we have been inundated (relatively speaking) with stories of ‘wandering’ bears sighted far from Arctic coastlines. These wandering bears are oddities to be sure but are not in any way an indicator of melting Arctic sea ice or lost habitat, as The Times (UK) has claimed in this latest example (Polar bear treks 1,500 miles south as Arctic hunting zone melts away).
by P. Homewood, April 6, 2021 in NotaLotofPeopleKnowThat
Seventh lowest? The NSIDC would of course like you to believe that this is all part of a declining trend. In reality, since the sharp decline beginning in 2004, sea ice extent has gone up and down, but with little overall change. This year and last year, average March extent has actually been higher than in 2006.
This March, extent was the 8th highest in the last 18 years, putting it around the median.
What about prior to 2004 though? Should we not be comparing this year with the 1981-2010 average?
Like it or not, and whatever the reason, the loss of summer ice in 2007 has had a direct effect on sea ice at all times of year since. Much of the sea ice is now thin, new ice, which melts more readily in summer. Consequently, winter ice takes longer to form as well.
It would probably take a climatic regime shift, such as occurred in the 1960s, for ice to return to pre 2004 levels. But the evidence shows that winter sea ice extent is currently stable.
Sea ice across the Arctic in the first week of February is a mix of highs and lows. Bering Sea is back up to almost normal coverage, as is the Barents Sea. However, ice coverage on the East Coast of Canada is the lowest its been in four decades. This is not yet a worry for polar bears because harp seals don’t pup until mid-March in this region so there is at least four weeks of potential ice growth that can happen before the seals are forced to pup on much reduced ice – where polar bears are sure to find them.
The polar vortex theory takes a beating: The claim a warm Arctic is behind the brutally cold winter conditions at the mid latitudes is shown by a Nature study to be scientifically baseless.
Now that Europe and North America are getting blasted by unusually severe winter weather, which climate alarmists predicted 20 years ago would be a thing of the past, the alarmists are desperate to find an explanation to escape embarrassment.
PIK science suggests warmth begets cold
They’ve come up with the polar vortex explanation: the bitter cold we are now experiencing at the middle latitudes is in fact due to the warmer Arctic, they say. And this wreaks havoc on the jet stream which in turn results in cold Arctic blasts dipping deep into the middle latitudes. Yes, cold winters are in fact exactly what we should expect in a rapidly warming world!
Levermann and Rahmstorf
For example the two media front men Anders Levermann and Stefan Rahmstorf of the Potsdam Climate Institute (PIK) have been telling this to the ever gullible German media outlets, like Bild and Spiegel. Yet, many suspect it’s scientific fraud designed to fool the public and to hide the fact that their global warming predictions are in reality glaring failures.
Regular NoTricksZone author Kenneth Richards notes on Twitter
Apparently Arctic sea ice volume was as low in the 1940s as it has been in the 2000s.
And the highest sea ice volume of the last 100 years was about 1979 – the year the Arctic sea ice record begins.

Abstract
We use model simulations from the CESM1-CAM5-BGC-LE dataset to characterise the Arctic sea ice thickness internal variability both spatially and temporally. These properties, and their stationarity, are investigated in three different contexts: (1) constant pre-industrial, (2) historical and (3) projected conditions. Spatial modes of variability show highly stationary patterns regardless of the forcing and mean state. A temporal analysis reveals two peaks of significant variability, and despite a non-stationarity on short timescales, they remain more or less stable until the first half of the 21st century, where they start to change once summer ice-free events occur, after 2050.
