Victory for climate skeptics, science in the Netherlands…erased historical heat waves get reinstated The Clintel (Climate Intelligence) reports that the KNMI (the Royal Netherlands Meteorological Institute) has reinstated seven historical heatwaves from the pre-1950 era that had previously been “erased” from official records due to statistical adjustments. Tropical days at De Bilt, version 0, 1 […]

“D–O signals [10-16°C warming events within decades to centuries] are not just seen in Greenland – they are registered globally.” – Liu et al., 2026 From 57,000 to 29,000 years ago, with Last Glacial atmospheric CO2 concentrations flatlining at ~200 ppm, there were 11 instances when Greenland abruptly warmed by 10-16°C within a span of […]

“[D]uring the last 6 ky, repeated, meter-scale, rapid (<300 y) rises alternated with meter-scale falls…interpreted as global.” – Higgs, 2026 A new study uses excavation evidence (wall ruins, coins, pottery) to suggest sea level rise (SLR) rates reached ~4 m in ~70 yrs (60 mm/year, or 20 times the modern rate of 3 mm/year) from […]

Across the globe, vermetid gastropods (shelled snails, or molluscs) are a “critical paleo-sea level indicator” for ancient coastline reconstructions (Angulo et al., 2026). Along the Brazilian coast, vermetid shell radiocarbon ages indicate the relative sea level (RSL) was “more than 2 m above present” between 6000 and 7000 years ago. (The charts shown in the […]

A large portion of the Greenland ice sheet that is today over 500 m thick did not exist during the Early to Mid Holocene. Prudhoe Dome (PD), a 2500 km² section of northwestern Greenland’s ice sheet (GIS), is today 500 to 600 m thick (Walcott-George et al., 2026). Approximately 6000-8000 years ago, or when atmospheric […]

Today’s sea levels are the lowest of the last several thousand years. Carbon dating evidence from the elevation of abandoned penguin rookeries (and other proxies) reveal relative sea level (RSL) was ~30 m higher than today across East Antarctica about 8000 years ago (Small et al., 2025). Following that highstand RSL fell rapidly at rates of […]

Northeastern China was at least 5°C (and up to 9°C) warmer than today and droughts (and floods) were far more extreme when CO2 levels were a “safe” 265 ppm. In a new study, scientists have determined that northeastern China’s droughts were far more frequent and intense during the Little Ice Age (LIA) than in the […]

New study: CO2 levels at least equivalent to today’s level of approximately 420 ppm would have been necessary 10,000 years ago. Germany’s online Report24 posted an article titled: “Why Ice Cores Lie: High CO2 Levels Characterized Early Times“. The article summarizes the study by Frans J. Schrijver titled “Historical CO2 Levels in periods of global […]

It is widely acknowledged that the enhanced CO2 fertilization effect due to the modern rise in atmospheric CO2 is the predominant driver of the dramatic increases in global greening, or “gross primary production” (GPP). Global greening attribution estimates for CO2 fertilization range from 70% (Zhu et al., 2016) to 86% (Haverd et al., 2020). As […]

Extremes hundreds of years ago…scientific analysis of historical documents about the 16th-century climate of Transylvania, Romania… reveals a pattern of intense extreme weather events, frequent and intense heat waves and droughts. The Germany-based European Institute for Climate and Energy (EIKE) presents it s latest video: “Kleine Eiszeit verursachte Wetterextreme – Klimaschau 232“ (Little Ice Age […]

The mechanisms driving the meters-higher sea levels a few thousand years ago do not support claims that CO2 is a driver. A comprehensive analysis (Zhang et al., 2025) of the South China Sea region indicates warmer sea water was fundamentally responsible for sea levels that were, on average, 2-3 meters higher (and in some regions […]

Throughout the last 10,000 years there have globally been much warmer and more extensive iceless periods than observed in the modern era. “There is reliable geological evidence that the temperature of most warming phases in the Holocene were globally higher or similar to that of the current warming period, Arctic sea ice was less extensive, […]
