Millennial-scale Arctic sea ice reconstructions do not corroborate alarmist claims of unprecedented sea ice losses in modern times. Using sea ice biomarker proxy (IP25), scientists (Kolling et al., 2023) have determined that the sea ice extent in the Labrador Sea was nearly absent throughout the year (close to 0.0 μg/gTOC) for much of the last […]

The timing of the dramatic Antarctic sea ice decline during the last deglaciation suggests solar forcing and sea ice retreat “instigated” century-scale climate warming and atmospheric CO2 change. This would appear to challenge the perception CO2 plays a causal role in glacial-interglacial sea ice and climate changes. From ~21,000 to 19,500 years ago, when CO2 […]

Yet another region of the world fails to cooperate with “global” warming instructions. New research (Zhang et al., 2023) finds the sea ice extent has undergone an overall increasing trend from 2005-2021 in the Sea of Japan, Yellow Sea, and Bohai Sea. “Over the past 17 years, the maximum sea ice extent in the marginal […]

The belief that modern sea levels and sea level change rates are unprecedentedly high takes another hit. Per a new study, sea levels were ~9.5 m higher than today about 8000 years ago (White Sea, northwestern Russia), then fell to ~7 m higher than today by around 4000 years ago. From that point in the […]

Back in the Early Holocene, when CO2 levels were said to be ~255 ppm, Arctic Svalbard was warm enough to accommodate abundant numbers of thermophiles, or warmth-demanding species. Only “remnants” of these species and their habitat exist in today’s much-colder Arctic. With the exception of a few centuries in recent millennia, today’s Svalbard (Arctic) is […]

The observed incapacity for southern elephant seals (SES) to withstand late 20th and early 21st century extreme cold and expanding sea ice conditions suggest coastal Antarctica (Victoria Land Coast, VLC) climate is colder and icier today than any time since the last glacial. A new study even suggests the last glacial (CO2 ~190 ppm) may […]

“Compared to the present climate, the Arctic climate in MH [Mid-Holocene] summer became warmer and had less sea ice” (Dong et al., 2022). While the modern Arctic “remains largely covered by sea ice in June and July,” the higher summer sea surface temperatures (SSTs) from about 3,000 to 7,000 years ago meant the East Siberian […]

Polar bear populations are stable to increasing with improved body condition in the 21st century. The alarmist narrative that says polar bears are threatened by sea ice losses is strongly at odds with real-world observations. A new study assesses the body condition of polar bears in the Gulf of Boothia – an immense 67,000 km² […]

Annual carbon dioxide (CO2) and methane (CH4) change rates lag behind changes in sea ice extent by 7 months and 5 months, respectively. This robust correlation is consistent with the conclusion that CO2 (and CH4) changes are responsive to temperature, not the other way around. It is commonly believed that the annual “squiggle” of the […]

Abundant polar bear remains dating to 8000 to 9000 years ago have been found on Zhokhov Island, which is today surrounded by year-round sea ice (even in summer). This Arctic latitude (76°N) is too cold and thus too ice-covered for polar bears to inhabit today. During the Early Holocene CO2 concentrations ranged between 255 to […]

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 […]

More evidence surfaces showing Greenland isn’t cooperating with the global warming narrative. The notorious “Climategate” e-mail exchanges between activist scientists like Drs. Phil Jones and Tom Wigley revealed how grave a concern it was in 2004 that “GREENLAND HAS BEEN COOLING SIGNIFICANTLY” since the 1950s. “…a warming trend occurred in the Nuuk fjord during the […]
