Temperature Trends In West Antarctica. A ‘Profound’ ~1°C Cooling Trend Across East Antarctica Since 1979 Is ‘Likely To Accelerate’ By Kenneth Richard on 12.
July 2021 Except for a few pockets of warming along the West Antarctic coast, surface air temperatures have cooled profoundly across East Antarctica – most of the continent, as well as the surrounding Southern Ocean – in the last 40 years (1979-2018). About 30% of the cooling can be explained by Madden-Julian Oscillation forcing. Climate change makes Antarctic summers… cooler.
Forty years of global warming have made East Antarctic summers even shorter and more miserably colder than they already were.
(Save the wilderness — burn coal now?) Surface Air temperature over East Antarctica (presumably in summer) from Hsu et al 2021. New Study Finds East And West Antarctica Have Profoundly Cooled By -2.8°C And -1.68°C Since 1979. By Kenneth Richard on 26.
July 2021 From 1979-2018 East Antarctica cooled -0.70°C/decade (-2.8°C), West Antarctica cooled -0.42°C/decade (-1.68°C), but the Antarctic Peninsula warmed 0.18°C/decade (0.72°C). Thus, as a whole, the Antarctic continent has cooled by about -1.5°C to -2°C during the same period CO2 rose from 337 to 410 ppm. Zhu et al., 2021 “The temperature trend from ERA5 is consistent with that from observations, in which a cooling trend dominates East Antarctica and West Antarctica, while a warming trend exists in the Antarctic Peninsula except during austral summer.”
Body Of Evidence: All Of Antarctica Is Cooling… Peninsula Cooling Since Long Before Greta Was Born. By P Gosselin on 19.
September 2021 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.
Scientists Find “Surprising” And “Statistically Significant” Cooling Trend Over Entire Continental Antarctica. By P Gosselin on 17.
September 2021 East Antarctica, which covers two thirds of the South Pole, has cooled a whopping 2.8°C over the past 4 decades; West Antarctica approximately 1.6°C. ..only tiny Antarctic Peninsula saw statistically insignificant warming. NASA Surface Station Data Show East Antarctica NOT WARMING Past 4 Decades…Cooling Trend. By P Gosselin on 7.

September 2020 Scientists extend a 15-station East Antarctica record from 1986 to 2017 and find a -0.7°C per decade cooling (-1.4°C total) until 2006, but no trend from 2006-2017. Doran et al (2002) reported “a net cooling on the Antarctic continent between 1966 and 2000”. Image Source: Doran et al., 2020 Obryk et al. (2020) – with P.T. New research shows the South Pole is warming faster than the rest of the world. Hmmmmm, or not ~cr Kyle Clem, Te Herenga Waka — Victoria University of Wellington Climate scientists long thought Antarctica’s interior may not be very sensitive to warming, but our research, published today, shows a dramatic change.
Over the past 30 years, the South Pole has been one of the fastest changing places on Earth, warming more than three times more rapidly than the rest of the world. My colleagues and I argue these warming trends are unlikely the result of natural climate variability alone. Antarctic temperatures recently plunged close to the theoretically coldest achievable on Earth! Guest inconvenience by David Middleton This story was previously discussed here at WUWT… But, why wasn’t this headline news in the Washington Post, New York Times, etc.?
Yes… That was a rhetorical question. Ultralow Surface Temperatures in East Antarctica From Satellite Thermal Infrared Mapping: The Coldest Places on EarthT. A. Scambos, G. An Inconvenient Truth: Few Signs Of Global Warming In Antarctica. By Paul Homewood From the Daily Caller: Antarctica has confounded scientists, defying the dire predictions of scientists the South Pole would shrink and exacerbate sea level rise in the coming decades.
Climate models predicted Antarctic sea ice would shrink as the world warmed, and that warming would boost snowfall over the southern continent. Neither of those predictions have panned out, and now scientists say “natural variability” is overwhelming human-induced warming. Antarctic Peninsula Has Been Cooling For Almost 20 Years, Scientists Confirm. By Paul Homewood From the “When it warms, it’s climate change; but when it cools, it’s natural variability” Dept: One of the big climate lies is that the Antarctic Peninsula is one of the fastest warming places on Earth.

By Kenneth Richard on 27. May 2019 A new paper published in Remote Sensing reports substantial summer cooling of Antarctica’s entire sea ice region due to an increase in surface albedo between 1982 to 2015. Zhou et al., 2019 The Characteristics of Surface Albedo ChangeTrends over the Antarctic Sea Ice Regionduring Recent Decades. 20+ Scientists: ‘No Continent-Scale Warming Of Antarctic Temperature Is Evident In The Last Century’ Image Source: State of the Climate, 2016 For several decades now, Antarctica has not been cooperating with the “global” warming narrative, as the continent as a whole has not been warming.
Several scientific papers have been published recently that document the lack of an anthropogenic warming signal for the Antarctic continent or the surrounding ocean, as well as the dominance of natural variability. Smith and Polvani (2016) concluded that warming of West Antarctica or the Antarctic Peninsula are predominantly natural.
“[We] conclude that there is little evidence of anthropogenic SAM-induced driving of the recent temperature trends … compelling evidence pointing to natural climate variability as a key contributor to the recent warming of West Antarctica and of the Peninsula“ 10 Of 10 Coastal Antarctic Stations Show Zero Warming Over Past Decades. Failed Scientists Need To Resign. By Kiryeand Pierre Gosselin Update: Another coastal station has been added: Novolazarevsk, so it’s 11 stations. Scientists Find Antarctica Is Rapidly Cooling And Any Ice Sheet Melt Is Not Due To CO2, But Natural. Natural variability rules in Antarctica. Scientists identify clouds, wind, and localized solar heating – not CO2 – as the factors driving ice melt.
