3 Paleontologist Studies Affirm North Sweden Was 3°C Warmer Than Today When CO2 Was Below 280 ppm

Share this… Facebook TwitterClaims the Swedish Scandes are unprecedentedly warm and tree-covered today “appear as large and unfounded exaggerations,” as the “climate and arboreal responses” of the last few decades “are still inside the frames of natural historical variation.” – Kullman, 2022 and Kullman, 2022a Extensive birch forest fossils can be dated to the early- […]

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 […]

Warmth Limits For Tree Growth Affirm Austria Was 4-7°C Warmer Than Today 2000 Years Ago

Warmth Limits For Tree Growth Affirm Austria Was 4-7°C Warmer Than Today 2000 Years Ago

Share this… Facebook TwitterRobust 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 […]

A Glaring Inconsistency In The Claimed Forcing Values Driving Past Versus Present Climate

A Glaring Inconsistency In The Claimed Forcing Values Driving Past Versus Present Climate

Share this… Facebook TwitterIt is claimed that an additional 60-75 W/m² of absorbed solar radiation can only produce a climate warming of 4-5°C. Doubling CO2 since pre-industrial times (280 to 560 ppm) is said to result in an additional 3.7 W/m² increase in radiative forcing. However, it is inconsistently claimed this ~20 times smaller value […]

Scientist: 'There Is No Climate Crisis' And 'No Particular Correlation Between CO2 And Temperature'

Scientist: ‘There Is No Climate Crisis’ And ‘No Particular Correlation Between CO2 And Temperature’

Share this… Facebook TwitterThe modern notion that human CO2 emissions are equivalent to a “deadly poison” may one day be viewed as “the greatest mass delusion in the history of the world.”  In a new paper published in the Journal of Sustainable Development, Manheimer (2022) summarizes some of the evidence for the lack of correlation […]

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 […]

New Study Finds Australian Sea Temperatures Multiple Degrees Warmer Than Today During The Last Glacial

New Study Finds Australian Sea Temperatures Multiple Degrees Warmer Than Today During The Last Glacial

Share this… Facebook TwitterSea temperatures in regions near Australia have failed to cooperate with a CO2-driven climate narrative. Glacial conditions and ~200 ppm CO2 levels were thought to have prevailed throughout most of the last 60,000 years across the Earth. But a new study finds sea temperatures near Australia were “3 to 5°C warmer than […]

Russian Temperature Records Are Not Cooperating With The CO2-Driven Climate Narrative

Russian Temperature Records Are Not Cooperating With The CO2-Driven Climate Narrative

Share this… Facebook TwitterTwo new studies indicate there has been no modern warming in the last centuries in western (Urals) and eastern (Kolyma) Russian mountain ranges. A new 27,000-year temperature reconstruction assesses it was ~2.5 to 4.8°C warmer than today from 8.9-5.2 ka BP in the Ural Mountains, or when CO2 is said to have […]

Belief Of Steady 5300 Year Climate Unravels: Ötzi Got Exposed “Again and Again”

Share this… Facebook TwitterChanging Holocene climate…was never steady Researchers say the 5300 year old Ötzi corpse didn’t remain covered by ice 5300 years long, but in fact was exposed again and again! Figure 1. Orthophoto of the findspot in the Tisenjoch (1) and other locations mentioned in the text (2: Kesselwandferner, 3: Weißseespitze, 4: Hintereisferner, […]

Scientists Identify More Locations Where It Is Colder Today Than Anytime In The Last 10,000 Years

Scientists Identify More Locations Where It Is Colder Today Than Anytime In The Last 10,000 Years

Share this… Facebook TwitterSites in Canada and Africa were warmer than today throughout nearly the entirety of the Holocene. Canada Per a new study, eastern Canada mean summer temperatures are 13.6°C and July temperatures average 15°C today. For nearly all of the Holocene the region was 1-1.5°C warmer (16.5°C, July) than it is now. In […]

Another Study Says Europe Was At Times Warmer During The Last Glacial When CO2 Levels Were 40% Lower

Another Study Says Europe Was At Times Warmer During The Last Glacial When CO2 Levels Were 40% Lower

Share this… Facebook TwitterThe Earth was still in ice age conditions 14,700 to 12,900 years ago, or during the “Bolling interstadial.” CO2 hovered near 230 ppm at that time, and yet “continental Europe was a few degrees warmer than present” (Toth et al., 2022). In recent years there have been multiple studies detailing a European […]
