A new surface air climate reconstruction method (Roberts et al., 2025) has determined neither the entire region from 60-90°S (Southern Ocean, Antarctica) nor the continental US have undergone any unusual or unprecedented warming in the modern era. The 60-90°S region had much warmer-than-modern periods throughout the last 12,000 years. Image Source: Roberts et al., 2025

Yet another region of the globe has failed to cooperate with anthropogenic “global” warming narrative. According to climate models constructed on the presumption that CO2 concentration changes are the driver of climate, Central Africa should have been warming in recent centuries in tandem with the rise of atmospheric CO2. However, scientists (Ménot et al., 2025) […]

Coral reefs expand and thrive as sea levels rise, whereas they undergo millennia of growth hiatuses and “turn-off” or “mass mortality” phases when sea levels fall. According to a new global sea level reconstruction (Feldman et al., 2025), global sea levels were meters higher than today 7000 to 5000 years ago. Global sea levels fell […]

“[T]he increase in absorbed solar radiation is primarily due to natural variations in cloudiness and surface albedo, which have served as the main forcing factors of the flux above the atmosphere over the last 2 decades.” – Diodato et al., 2025 It is commonly accepted that there has been a satellite-observed (CERES) cloud cover albedo […]

“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 […]

Natural cycles drive our climate The latest video by the Germany-based European Institute for Climate and Energy (EIKE) looks at CO2 and the troublesome Medieval Warm Period, which has long been a thorn for climate alarmists. Antarctica was warmer during the Medieval Warm Period, enhancing penguin population. Image generated by Grok Hat-tip: Klimanachrichten The Medieval […]

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. […]

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

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 […]
