2M Years Ago Corals, Manatees Occupied N. Greenland Seas As Elephants Browsed A Forested Landscape

Share this… Facebook TwitterAn ancient vegetative and fauna ecosystem discovery in northernmost Greenland reveals how substantially warmer polar climates were when CO2 levels were said to be much lower than today.

Greenland Temperatures Rose 1°C In 1994 ... Since Then They Have Been 'Relatively Constant'

Greenland Temperatures Rose 1°C In 1994 … Since Then They Have Been ‘Relatively Constant’

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 […]

New Study Indicates NW Greenland Was 'At Least 9°C' Warmer Than Today When CO2 Was ~300 ppm

New Study Indicates NW Greenland Was ‘At Least 9°C’ Warmer Than Today When CO2 Was ~300 ppm

Share this… Facebook TwitterEvidence of abundant lakes and ponds and the remains of vascular plants, warmth-demanding beetles, sponges, spruce forests…in a newly-discovered organic-rich deposit 480 m above sea level in High Arctic (76.4°N) northwest Greenland indicates the local climate was similar to that of today’s southern Greenland (~60°N) and North America during the Early Pleistocene […]

Why Is Antarctica's Climate Considered 'Global' But Arctic Siberia's Is Not?

Why Is Antarctica’s Climate Considered ‘Global’ But Arctic Siberia’s Is Not?

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 […]

Another New Study Affirms The Arctic Was Warmer With Less Sea Ice During The Mid-Holocene

Another New Study Affirms The Arctic Was Warmer With Less Sea Ice During The Mid-Holocene

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 […]

New Study: Birch And Pine Forests Far More Abundant In The Arctic During The Holocene Than Today

New Study: Birch And Pine Forests Far More Abundant In The Arctic During The Holocene Than Today

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 Reindeer On Wrangel Island Have Experienced Mass Die-Offs Due To 21st Century Icing Events

The Reindeer On Wrangel Island Have Experienced Mass Die-Offs Due To 21st Century Icing Events

Share this… Facebook TwitterWrangel Island reindeer numbers plummeted from 8,500 to 400-500 individuals within 5 years (2002-2007) due to repeated cold weather-related icing episodes resulting in starvation. 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 […]

Another New Study Indicates Polar Bears Benefit From Sea Ice Loss Due To Enhanced Prey Accessibility

Another New Study Indicates Polar Bears Benefit From Sea Ice Loss Due To Enhanced Prey Accessibility

Share this… Facebook TwitterPolar 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 […]

There Is No Detectable Link Between Greenland's Climate And Atmospheric CO2 Changes

There Is No Detectable Link Between Greenland’s Climate And Atmospheric CO2 Changes

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 […]

Trend Change? Greenland Ice Mass Loss Has Been Decelerating Since 2012

Share this… Facebook TwitterGreenland’s Ice Mass Balance 2021/22 By Die kalte Sonne Autumn has begun. Time for the Greenland mass balance. We have digitized the Polar Portal’s graph of the accumulated surface mass balance and have come up with a value of 467 Gt. That’s 100 Gt or 27% above the 1981…2010 mean! Together with […]

Polar Opposite: Polar Bears Require Thin Ice Or Open Water To Survive

Polar Opposite: Polar Bears Require Thin Ice Or Open Water To Survive

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 […]

Canadian Arctic Archipelago Blocked By Thick Multi-Year Ice…August Arctic Sea Ice Rebounds

Share this… Facebook TwitterIn terms of Arctic sea ice and hurricane activity this year, the climate ambulance chasers have been quiet. Late summer Arctic ice has stopped shrinking The DMI graph shows the size of sea ice areas in the Arctic in August from the beginning of satellite measurements in 1979 to 2022 (red line). […]
