105 More Global Non-Warming / Non-Hockey Temperature Records Added To Database In 2021 – Rise With That?
Via Kenneth Richard above 31. January 2022
Since 2019, more than 350 peer-reviewed scientific papers have been published showing no warming in the modern era and/or temperatures much warmer than today as CO2 levels range from 180 to 280 ppm (Holocene, Pleistocene).
Below is a link to an updated database (currently including 2021) of non-hockey temperature records from locations around the world.
These hundreds of papers show that a) the Earth has been several degrees warmer than it is today during the past 11,700 years (the Holocene), and b) there is nothing unusual about temperature changes in the modern era.
Here are the first 8 articles on the 2021 list.
Zhou et al, 2021 The South China Sea was warmer by ~4°C SST during the Holocene between… 1994-2004 coldest temperature in last 6000 years
Tarasov et al., 2021 (full paper) Arctic Siberia was between 3.5 and 5 °C warmer than it is today during the height of the last ice age (180 ppm CO2), providing year-round grass for large herbivores
Environment during the spread of anatomically modern humans across North Asia 50–10 cal kyr BP…. North Asia (here, the Russian Federation east of the Urals) played an important role in the spread of anatomically modern humans (AMH) across Eurasia during the Upper Paleolithic. (UPS). … Contrary to the long-held view that glacial climates were generally colder than the present, these proxy records reveal evidence that summers were several degrees Celsius warmer than today., which provides additional advantages to human activities. Another benefit to large herbivores, and thus human survival, was the generally low winter rainfall (similar to that in the modern steppe regions of Mongolia), Sustainable year-round cattle grazing. These factors appear to outweigh current colder winter conditions and promote AMH colonization in North Asia even during the last glacial maximum (LGM). 30‒18 cal kyr BP. … [R]The environmental-built mean July temperature was 12°C for most of the last cold in the study area, where the modern July mean temperature is about 7°C … [A]At least 3.5°C above current summer temperatures during the last Glacial Maximum [CO2 180 ppm] in the south of eastern Siberia
Wetterich et al., 2021 The Siberian Arctic had “warmer temperatures than today (up to 4–4.5 °C)” during the last ice age (180 ppm CO2), or between “39 and 31 cal kyr BP”
Between 48 and 38 cal kyr BP, the chironomid fauna is dominated by typical aquatic taxa, although chironomid numbers and diversity are significantly reduced. between 46 and 44 cal kyr BP when TJuly was regenerated increased to 1.5°C above modern. The 44 to 41.5 cal kyr BP interval was characterized by the highest chironomid diversity and concentrations. Biomes dominated by the type Heterotrissocladius grimschawi occur in autotrophic lakes and are indicative of temperate conditions with an optimal temperature of 11–12 °C. … The reconstructed TJuly is slightly different from modern with TJuly warmer than today at about 41 cal kyr BP. … At approximately 51 cal kyr BP and 40 cal kyr BP in Bykovsky’s records, the appearance of the temperate aquatic plant Callitriche hermaphroditica provides evidence of means TJuly of 12°C or higher, while the discovery of a taxon on the Thesium savannah dating to 51 cal kyr shows TJuly of 15°C or more. The chironomid-based TJuly reconstruction for MIS 3 from the Sobo-Sise Yedoma record showed some variation (Figure 5) and indicated temperatures are warmer today (>11°C) at around 51 cal kyr BP, 46-44 and 41 cal kyr BP demonstrates general consensus with the plant macrofossil-based TJuly estimate from the records of Bykovsky Yedoma (Kienast et al., 2005). … Reconstruction of TJuly from the western part of the Yana-Indigirka lowland (east of the study area) shows the same or warmer than today (up to 4–4.5 °C) and annual precipitation is higher than today (up to 50–100 mm) between about 39 and 31 cal kyr BP (Pitulko et al., 2017)
City-Mazens et al., 2021 22,000 years ago (180 ppm CO2) Southern Ocean surface temperature peaked at 13.6°C, about 4-5°C warmer than today (~9°C)
Cruz et al, 2021 Argentina was 1.7°C to 4.4°C warmer than it is today during the 1800s
The paleontological history of Tixi Cave (Table 3, Figure 4), compared with the present, suggests a colder (−3.3°C) and drier (−274.6 mm) climate for the Pleistocene transition -Early Holocene (12,287 ± 212–11,609 ± 218ca BP). These cold and dry conditions remained during the Middle Holocene (5592 ± 79ca BP) with a lower mean annual temperature (−2.4 °C) and lower precipitation (−201.2 mm) compared to present. The change happened in Post-Holocene IV (3496 ± 81ca BP) with warmer and wetter conditions than present, which shows an increase in mean annual temperature (+3.5°C) and annual precipitation (+90.8mm). These warm and humid conditions were maintained for the remainder of the Late Holocene III – I (1656 ± 96–160 ± 120 cases of BP) with an increase in average annual temperature from 1.7°C to 4.4°C and annual rainfall 27.5–263.6mm, higher than present.
Nazarova et al, 2021 (full) Eastern Russia was 1.5°C warmer than it is now during the Medieval Warm Period (AD 750-1250)
Medieval climate optimum (Nara – Heian – Kamakura period in Japan) reproduced for the eastern part of Primorsky Krai during the period 1250 to 750 cal year BP has a humid climate with summer temperatures around ca. 1.5°C higher than current. The period between 750 and 250 cal years BP correlates with the Little Ice Age: summer temperatures have dropped to 1.5–2 °C below modern temperatures.
Shuttleworth et al, 2021 The sub-Antarctic Atlantic was ~2°C warmer (see diamond) ~4000 to ~5000 years ago
Allan et al, 2021 Greenland was 5-7°C (4-5°C vs 10-12°C) warmer than it is today between 7,500 and 5,500 years ago.
Present…Summer SST ranges from 4.0-5.2°C (Ribergaard 2014). … Division B2 (from ~ 10 to 5 ka BP) marked by… peak summer SST ranges from 6 to 12°C with an average of ~9°C… Sub-zone A3 (from ~2.7 to ~1.3 ka BP) is characterized by cold conditions with summer SST of ~5°C… Optimal thermal conditions… The estimated July surface air temperature (SAT) from pollen grains is ~10 to ~12°C from ~7.5 to ~5.5 ka BP (Frechette & de Vernal 2009).
