The warmest 50-year period in northeastern China occurred from 1844-1893. Li et al., 2024 “Compared with single years, in general, high or low temperatures that persist for many years will more significantly affect the growth of trees [30]. When we defined years with T12-1 ≥ −10.73 °C (Mean + 1σ) and T12-1 ≤ −12.61 °C […]

AGW proponents use subjective forcing models and unmeasured estimates of past solar activity to claim humans drive warming. A scientist’s (Larminat, 2023) reassessment finds the Sun can drive climate, equilibrium climate sensitivity (ECS, 2xCO2 + feedbacks) is 1.14°C, and human forcing is overestimated. Because there have been no direct measurements of solar activity until the […]

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. […]

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 […]

“Chironomid‐based temperature reconstructions in the central eastern Alps showed…between ca. 10 000 and 8600 cal a BP…a thermal maximum of up to 4.5°C higher temperatures than present” – Caf et al., 2023 With the exception of a century or two during the Little Ice Age (~1500-1900 CE), the European Alps have had a much higher […]

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 studies identify sites in Portugal, southern Africa, and Arctic Svalbard that have not warmed in the last few centuries. Daily temperature records in northern Portugal indicate no net warming from 1863-2004 (Nunes, 2022). Also, the Medieval Warm Period was warmer than the 21st century at this location. Image Source: Nunes, 2022 Affirming this temperature […]

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 – […]

Several new and recent studies have affirmed that the waters surrounding South America – from Peru to Chile to Argentina to Brazil – were several degrees warmer and sea levels multiple meters higher than today until the Little Ice Age centuries. A new study suggests ~4,000 to 5,000 years ago coastal Argentina’s sea surface temperatures […]

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 […]

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 […]

Despite all the hysterical media claims, the earth’s climate is still extremely hostile and deadly in terms of cold. Warming would save millions of lives. Yesterday’s post looked at how cold is far more deadly than heat. Comparatively few people die from heat. Cold is the real killer. Image: The Lancet. After all, people can […]
