4 More Temperature Reconstructions Fail To Support The 'Unprecedented' Global Warming Narrative

4 More Temperature Reconstructions Fail To Support The ‘Unprecedented’ Global Warming Narrative

New studies find recent non-warming and/or a warmer Medieval Warm Period. From 1785-2015 (231 years), the warmest 21-year period in India’s Himalayan region occurred from 1890-1910 (Rastogi et al., 2023). The years spanning 1995-2015 were the 4th warmest and 1946-1966 was the 2nd warmest period.   So, overall, the region has cooled slightly since 1890. […]

New Study: Modern Central Asia Climate Halfway Between Medieval Warmth And Little Ice Age

New Study: Modern Central Asia Climate Halfway Between Medieval Warmth And Little Ice Age

The mean annual temperature was 2-3°C warmer than present during the Holocene Thermal Maximum in arid central Asia. Over the last few millennia, Silk Road human civilizations (e.g., Sui, Tang, Ming, Yuan Dynasties) flourished during warm periods and declined during cool periods (Ding et al., 2023). The modern hydroclimate in this region does not stand […]

New Study: Roman And Medieval Warm Periods Were 2.8°C Warmer Than 1970-2000 In Central China

New Study: Roman And Medieval Warm Periods Were 2.8°C Warmer Than 1970-2000 In Central China

A series of paleoclimate lake reconstructions across China in recent years have failed to support the global-scale warming narrative. Per a new lake temperature reconstruction (Li et al., 2023) from Central China, there were distinct “warm intervals during the RWP [Roman Warm Period] (403–413 CE), with a temperature 2.89°C higher than that of the mean […]

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

Claims 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- to mid-Holocene in […]

New Study: The Reality Of The Medieval Warm Period Confirmed By Changes In Agricultural Practices

New Study: The Reality Of The Medieval Warm Period Confirmed By Changes In Agricultural Practices

Due to a “relatively stable warm climate” the Medieval Warm Period (800 to 1300 CE) was a period of expanding Scandinavian population, increasing trade, food and goods production. There has been a ~500 zettajoule (ZJ) increase in global ocean heat energy since 1750. The Medieval Warm Period global ocean had 1000 ZJ more heat energy […]

New Study: Greenland 'Must Have Been At Least 3°C Warmer' Than Today During The Early Holocene

New Study: Greenland ‘Must Have Been At Least 3°C Warmer’ Than Today During The Early Holocene

These much warmer Greenland temperatures imply that the elevation of the ice sheet was 400 meters lower than it is today from about 6,000 to 10,000 years ago. Scientists (Westhoff et al., 2022) report that the two largest Greenland melt events in the last few hundred years occurred in 2012 and in 1889 CE – […]

New Study: Sea Of Japan 3-6°C Warmer, Sea Levels 2-3 Meters Higher 8000-5000 Years Ago

New Study: Sea Of Japan 3-6°C Warmer, Sea Levels 2-3 Meters Higher 8000-5000 Years Ago

During the Medieval Warm Period surface temperatures were 1-1.3°C warmer and sea levels 1 meter higher in the southern Far East Russia study region. Another new study (Lyashchevskaya et al., 2022) casts doubt on the claims of an unprecedentedly warm modern climate. Even though the atmospheric CO2 levels were a “safe” 265 ppm, the Primorye […]

New Study: Alpine Glaciers Were Smaller Than Today For 7,400 Of The Last 10,000 Years

New Study: Alpine Glaciers Were Smaller Than Today For 7,400 Of The Last 10,000 Years

Swiss Alps glacier extents were smaller than 2000 C.E. during  the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer. Schimmelpfennig et al., 2022 “…the glacier was smaller than its 2000 CE extent for a total of ∼7.4 kyr during the Holocene.” Image Source: Schimmelpfennig et al., 2022 Another […]

One New Coral Reef Study Wipes Out Four Climate Alarm Narratives In One Fell Swoop

One New Coral Reef Study Wipes Out Four Climate Alarm Narratives In One Fell Swoop

Corals thrive in multiple-degrees-warmer-than-today waters and their growth is stunted in cooler environments. The warnings peddled by climate alarmists often characterize Earth’s 500 billion corals as critically endangered by modern global warming. But the science itself says corals have been and continue thriving in the Current Warm Period – just as they have in past […]

New Study: In Northern Poland The Medieval Warm Period Was 3°C Warmer Than Today

New Study: In Northern Poland The Medieval Warm Period Was 3°C Warmer Than Today

A new analysis has Poland’s July temperatures hitting 20.6°C in Medieval times, whereas they’re only 17.4°C today. The temperature record for this region also shows today’s temperatures are not much different than they were during the Little Ice Age. Another chart contained in the study (Pleskot et al., 2022) shows North America’s and Europe’s mean […]

Hundreds More Papers Published In 2021 Support A Skeptical Position On Climate Alarm

In 2021, several hundred more scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. These scientific papers affirm the position […]

105 More Non-Global Warming/Non-Hockey Stick Temperature Records Added To The Database In 2021

Since 2019,there have been over 350 peer-reviewed scientific papers published showing no warming in the modern era and/or much warmer temperatures than today when CO2 levels ranged from 180 to 280 ppm (Holocene, Pleistocene). Below is the link to the updated (now including 2021) database of non-hockey temperature records from locations across the world. These […]
