Share this… Facebook TwitterA warming event that spans only one year, with decades of stable temperatures before and after, would not appear to align with rapidly rising human CO2 emissions or a gradually rising atmospheric CO2 concentration. From 1958 to 2020, as CO2 rose from 320 ppm to 410 ppm, Greenland had a warming period […]

Share this… Facebook TwitterIndependent analyses from multiple independent sources indicate Arctic Siberia was 3 to 5°C warmer than today during the peak of the last glacial, or when CO2 levels were below 200 ppm. Measurements from Antarctica’s ice sheet are almost invariably used to characterize both the global-scale atmospheric CO2 levels and climate for the […]

Share this… Facebook Twitter“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 […]

Share this… Facebook TwitterTrees, plants, and animal dwellers tell a much different story about the climate of the last 11,000 years than those claiming the modern Arctic temperatures are unusually warm. A “warmer than present” Arctic climate from 9,000 to 3,500 years ago (Brown et al., 2022) was suitably warm enough to sustain aquatic species […]

The alarmist activists who routinely claim the Arctic biosphere is threatened by a warmer climate seem to ignore the Arctic’s mass die-off catastrophes linked to cold temperatures and […]

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 […]

Share this… Facebook TwitterGreenland’s climate changes are remarkably uncorrelated with climate model expectations and changes in atmospheric CO2. When CO2 levels were in the mid-200s parts per million (11.7 to 4.5 thousand years ago) the Arctic and northern Greenland were 2-4°C warmer than now, ice margins were 80 km behind today’s, ice-free open water conditions […]

Share this… Facebook TwitterAbundant 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 […]
