“Until now, the origin of the climate dynamics of the Central Andes during the last millennium has been speculative. On the basis of statistical evidence, we have identified solar variability as its origin.” – Schittek et al., 2025 In a new study, scientists have determined: 1) The Little Ice Age (LIA) was a global-scale cold […]

A robust 1750-2020 temperature proxy reconstruction (Karlsson et al., 2025) from a spruce forest in the Norwegian mountains identifies yet another location on the globe unaffected by anthropogenic “global warming.” Image Source: Karlsson et al., 2025

Reconstructed ice core CO2 values and modern CO2 and CH4 measurements do not support the narrative that human emissions are driving changes in atmospheric greenhouse gas concentrations. New research extensively reviews the “pitfalls” of believing the conventional wisdom about modern CO2 concentration variations, as well as the “flaws” in reconstructed CO2 values from ice cores. […]

“Our findings are unexpected: despite rising sea surface temperatures, global Eo [ocean evaporation/water vapor] has decreased in the most recent decade.” – Ma et al., 2025 A 2024 study published in PNAS again confirmed climate models fail to simulate what happens in the real world with regard to fundamental climate change variables like water vapor, […]

It turns out the benefits of rising CO2 concentrations offsets any projected agricultural damage from climate warming. In 2023 US EPA (Environmental Protection Agency) activists dubiously raised the “social cost of carbon” (SCC) five-fold due to unsupportable forecasts of agricultural deterioration and declining crop yields resulting from doubled CO2 and consequent climate warming. The 500% […]

There has been no net warming at 3 mid-latitude study sites in China since 1916 (Tongbai Mountain), 1663 (Shimen Mountain), and 1541 (Xinlong). Zheng et al., 2025

Because the current state-of-the-art general circulation models (GCMs) cannot simulate the trends and variances in global precipitation over the last 84 years (1940-2023), their usefulness should be reconsidered. Hydrological processes – ocean circulation, water vapor, clouds – are key components of climate, easily overshadowing the impact of anthropogenic CO2 emissions by a factor of 2,100 […]

In a region of the world where tide gauges are not compromised by land subsidence or uplift, sea levels have not been observed to be rising since measurements began in 1894. According to a new study, when sea levels rise it usually has more to do with declining land movement (subsidence) or 20- to 60-year […]

Fifteen more new studies published in 2024 document meters-higher sea levels across the world during the Mid-Holocene, when CO2 hovered near 260 ppm. There were 45 studies published from 2022 to 2024 indicating sea levels were approximately 2 to 3 meters higher across the world about 7000 to 4000 years ago before declining to today’s […]

“Based on the records of the δ¹⁸O stalagmite , the [Holocene Thermal Maximum] occurred between 10.9 and 6.7 ka [Honshu, Japan], reaching its peak temperature (15.0°C) around 7.0 ka. At this time, temperatures were approximately 3°C warmer than present.” – Murata et al., 2025 In a new study, scientists have used oxygen and carbonate isotope […]

Scientists presumably intending to report unusual modern warming in response to anthropogenic activities actually indicate all or nearly all modern warming and treeline advances at a Rocky Mountain ice patch site occurred from the 1910s to the 1940s. An interesting observation found in the body of a new study (Pederson et al., 2025) is that […]

Studies from Central China, Russia, and Central Europe indicate there was just as much (0r more) warming and drought prior to 1900, or when CO2 concentrations were under 300 ppm. A new 1606 to 2016 Central China winter (minimum) temperature reconstruction (Jiang et al., 2024) reveals cold periods only occurred in 9 years of the […]
