Climate alarmists hate this inconvenient fact: hundreds of temperature reconstructions show that the northern hemisphere was much warmer over much of the past 10,000 years (Holocene) than it is today. HAT-TIP: Klimaschau here Massive 66 temperature reconstructions One recent study: Arctic glaciers and ice caps through the Holocene: a circumpolar synthesis of lake-based reconstructions by […]

Growing sea ice Despite all the alarmist claims of an Antarctic meltdown, it is well known that the trend for sea ice extent at the South Pole has been one of growing ice rather than shrinking ice over the past 4 decades. Naturally many factors influence polar sea ice extent, such as weather patterns, winds, […]

I thought the planet today was warm – too warm, we keep hearing. Well the Arctic was a heck of a lot warmer 53 million years ago. Today’s climate by comparison is downright frigid. The Bild der Wissenschaft reports on a paper appearing in the Proceedings of the Royal Society here that shows the Arctic was covered with […]

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 […]

Moving goalposts Sediment samples show Arctic was warmer 10,000 years ago and was ice free in the summertime. Moreover, the researchers say “it’s uncertain” if Arctic sea ice will disappear in the summertime before 2063. Image: NASA (public domain) The Aarhus University conducted a study that confirms sea ice disappeared from the Arctic during the summer […]

Earth’s average annual temperature fluctuated by as much as 35°C (at high latitudes) from one millennial-scale period to the next during the last glacial period. A recently-published 2-part study (Smul′skii, 2022a and 2022b) utilizes established orbital and insolation data to calculate Earth’s average temperature today (0 k years ago), 14.4°C, and at 25°N, 45°N, 65°N, […]

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 […]

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 […]

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 […]

Robust evidence from bison remains recovered from the Austrian Alps in 2020 and 2021 invalidate claims modern Alpine temperatures are unusually warm. A new study suggests that from about 6000 to 1200 years ago European bison fed on deciduous tree/vegetation that grew at Alpine altitudes reaching around 800 m higher than they do today. Known beech […]

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 […]

A new study details how a much warmer climate than today led to the disappearance of glaciers and ice caps during the sub-300 ppm CO2 Early to Middle Holocene. The Arctic’s modern ice extent is among the largest of the last 10,000 years. Glaciologists Larocca and Axford (2022) have synthesized a comprehensive record of Arctic-wide […]
