The IPCC 6th Report seems to have missed a lot, hasn’t it? Recent publications since the 5th Report show ALL OF ANTARCTICA, including the peninsula, has cooled since the late 1990s.
Friday I wrote about how the entire continent of Antarctica (except its peninsula) was found by leading scientists to be cooling significantly.
The publication by Zhu et al, however, found that the Antarctic Peninsula had been warming – but not a statistically significant rate – over the past 4 decades.
Now in a reader comment Kenneth has brought our attention to three scientific publications that show the peninsula has in fact been cooling since the late 1990s, after having warmed since the early 1950s!

Here are the three terribly inconvenient papers for those still believing the lie the South Pole is warming, when in reality it is cooling at a “statistically significant” rate.

According to Kenneth: “The cooling since the 1990s hadn’t fully taken over the warming from 1979-1999 yet, so that’s why the overall trend is still a slight, statistically insignificant warming when referencing the entire 40-year period.”
Which goes far to explain why alarmists have been inventing all sorts of warming South Pole currents melting the underside of glaciers and leading to the alarmists’ prophesized sea level rise.
Meaning, they know darn well that Antarctica is not warming as they claim.
Social media and the MSM have been heating us up for last 50 years particularly our insecurities .

”A trip to a melting glacier will shape how the BBC’s new climate editor, Justin Rowlatt, reports on the story of climate change.
You cannot help but be awed by the scale of Antarctica, the great white continent.
I visited just before the pandemic struck and it is impossible not to feel humbled in the presence of something that seems so much bigger and more powerful than you.
But that sensation is an illusion.
When we finally flew over the front of the enormous glacier after weeks of travelling, I found myself staring down at an epic vision of shattered ice.
As I wrote at the time, it felt like I’d reached the frontline of climate change; a place where the equilibrium that has held our world in balance for thousands of years was slipping and crashing.”
This guy has a vivid imagination.
Here are a few other recent studies of temperature trends across the Antarctic continent.
As you should expect – it’s complicated

“Thirteen of the 17 stations have experienced a positive trend in their annual mean temperature over the full length of their record, with the largest being at Vernadsky (formerly Faraday) (0.46° ± 0.15 C dec−1) on the western side of the Antarctic Peninsula. The deepening of the Amundsen Sea Low as a result of the more positive SAM and changes in the IPO and PDO have contributed to the warming of the Peninsula. Beyond the Antarctic Peninsula there has been little significant change in temperature. The two plateau stations had a small cooling from the late 1970s to the late 1990s consistent with the SAM becoming positive, but have subsequently warmed. During spring there has been an Antarctic‐wide warming, with all but one station having experienced an increase in temperature, although the only trends that were significant were at Vostok, Scott base, Vernadsky and Amundsen‐Scott. In this season much of the Peninsula/West Antarctic warming can be attributed to tropical Pacific forcing through the IPO/PDO. “

“Over the last three decades, the South Pole has experienced a record-high statistically significant warming of 0.61 ± 0.34 °C per decade, more than three times the global average. Here, we use an ensemble of climate model experiments to show this recent warming lies within the upper bounds of the simulated range of natural variability. The warming resulted from a strong cyclonic anomaly in the Weddell Sea caused by increasing sea surface temperatures in the western tropical Pacific. This circulation, coupled with a positive polarity of the Southern Annular Mode, advected warm and moist air from the South Atlantic into the Antarctic interior. These results underscore the intimate linkage of interior Antarctic climate to tropical variability. Further, this study shows that atmospheric internal variability can induce extreme regional climate change over the Antarctic interior, which has masked any anthropogenic warming signal there during the twenty-first century.”
With tropical NV the causation …..

“Recent Antarctic surface climate change has been characterized by greater warming trends in West Antarctica than in East Antarctica. Although this asymmetric feature is well recognized, its origin remains poorly understood. Here, by analyzing observation data and multimodel results, we show that a west-east asymmetric internal mode amplified in austral winter originates from the harmony of the atmosphere-ocean coupled feedback off West Antarctica and the Antarctic terrain. The warmer ocean temperature over the West Antarctic sector has positive feedback, with an anomalous upper-tropospheric anticyclonic circulation response centered over West Antarctica, in which the strength of the feedback is controlled by the Antarctic topographic layout and the annual cycle. The current west-east asymmetry of Antarctic surface climate change is undoubtedly of natural origin because no external factors (e.g., orbital or anthropogenic factors) contribute to the asymmetric mode.”

“While West Antarctica has experienced the most significant warming in the world, a profound cooling trend in austral summer was observed over East Antarctica (30°W to 150°E, 70° to 90°S) from 1979 to 2014. Previous studies attributed these changes to high-latitude atmospheric dynamics, stratospheric ozone change, and tropical sea surface temperature anomalies. We show that up to 20 to 40% of the observed summer cooling trend in East Antarctica was forced by decadal changes of the Madden-Julian oscillation (MJO). Both observational analysis and climate model experiments indicate that the decadal changes in the MJO, characterized by less (more) atmospheric deep convection in the Indian Ocean (western Pacific) during the recent two decades, led to the net cooling trend over East Antarctica through modifying atmospheric circulations linked to poleward-propagating Rossby wave trains. This study highlights that changes in intraseasonal tropical climate patterns may result in important climate change over Antarctica.”
Vulcanoes under West Antarctica may contribute some tenth or hundreths of degrees to a the measured temp. change. A paper writing about unknown reasons can’t be taken for serious same as data based on models.
