Another New Study Shows The Siberian Arctic Is Warmer When CO2 Is Low And Colder As CO2 Rises

Another New Study Shows The Siberian Arctic Is Warmer When CO2 Is Low And Colder As CO2 Rises

In the last 25,000 years there has been an anti-correlation between rising CO2 and the Siberian Arctic temperature – the opposite of what is claimed by proponents of the anthropogenic global warming narrative. According to a new study, Arctic Siberia was 4°C warmer than it is today from 15,000 to 11,000 years ago, when CO2 […]

Study: Northern Greenland Was Ice Free, Forested ~125k Years Ago, Adding 3 Meters To Sea Levels

Study: Northern Greenland Was Ice Free, Forested ~125k Years Ago, Adding 3 Meters To Sea Levels

During the last interglacial (LIG) 127 to 119k years ago, when CO2 levels were said to be only 275 ppm, Greenland’s Camp Century surface was ice free, vegetated. Today this same site is buried under a 1.4 kilometers-high ice sheet. The Arctic was sea ice free during the LIG (Diamond et al., 2021). Image Source: […]

Scientists Say A 6°C Warmer-Than-Today Arctic Is 'Optimal' For Thermophile Species

Scientists Say A 6°C Warmer-Than-Today Arctic Is ‘Optimal’ For Thermophile Species

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 […]

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

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

An 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. Reconstruction of the Kap København Formation ecosystem 2 million years ago. Image credit: Beth Zaiken. Source: Sci.News The northern coasts of Greenland are today a barren polar […]

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’

A 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 of 1°C that […]

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

Evidence 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 ice age. Scientists […]

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?

Independent 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 last 10s to […]

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

“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 […]

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

Trees, 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 like sponges and […]

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

Wrangel 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 ice in recent […]

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

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 […]

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

Greenland’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 prevailed, and Greenland […]
