There is nothing unprecedented or even significant about modern warming magnitudes or rates. Antarctic ice cores are routinely used to represent not only global-scale CO2 records, but global temperature records over the last 800,000 years. Interestingly, if we compare modern Antarctica to paleo Antarctica we learn “no continent-scale warming of Antarctic temperature is evident in the […]

Climate changes fostered by “unforced natural climate variability” may be more than an order of magnitude larger than the climate changes commonly attributed to anthropogenic forcing. In a new study, scientists have attempted to identify the mechanisms explaining Greenland’s many historical (~80,000-11,700 years ago) climate changes that amounted to 10-15°C “in a decade or two.” […]

Warming across Germany in the last 3 decades can be explained by declining cloud and aerosol albedo and consequent rising solar radiation. Not CO2. Another new study affirms clouds and aerosols play a key role in explaining trends in solar surface radiation (SSR), which is “essential for the global energy cycle driving the climate system.” […]

Pollen-reconstructed New Brunswick (Canada) spring temperatures affirm the Medieval Warm Period or Medieval Climate Anomaly (MCA, 900-1400 CE) was 1°C warmer (3.2°C vs. 2.2°C) than both the Little Ice Age (LIA, 1400-1850 CE) and modern period (1850 to present). Other sites in this region also show no net warming since the 1800s and 1-3°C cooling […]

For the last 3000 years the Beaufort Sea region has had “permanent sea ice.” According to a new study, there was “no sea ice” in the Arctic’s Beaufort Sea from 11,700 to 8200 years ago. During this period, summer sea surface temperatures (SSTs) averaged ~7°C, varying up to 9.6°C. “The Early Holocene (11.7−8.2 ka) is […]

“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 […]

The Intergovernmental Panel on Climate Change (IPCC) has for decades advocated net-zero governmental policies to reduce anthropogenic CO2 (aCO2) emissions. This advocacy is rooted in the non-physical assumption that aCO2 molecules are special, as they remain in the atmosphere for decades to centuries. Proponents of the anthropogenic global warming (AGW) narrative even claim aCO2 removal […]

“[S]ea ice loss did not lead to a reduction in BC [body condition] among adult BS [Barents Sea] bears. Rather, after around 2000…both males and females of different reproductive categories increased in body condition for the following two decades.” — Aars et al., 2026 Thick sea ice is not a necessary condition for polar bear […]

Modern climate science is constructed on a foundation of belief. Svante Arrhenius is known as the “godfather” of the CO2 greenhouse effect. Today’s climate models are still based on his 1896 thought-experiment calculations of CO2’s imagined capacity to warm Earth’s surface (71% water) out of a frozen solid state by tens of degrees. His one-dimensional […]

Decades of satellite data confirm the globe has been substantially greening – as defined by rising Leaf Area Index (LAI) values – since the 1980s. The CO2 fertilization effect (CFE) enhances plant productivity via improved light use efficiency and water use efficiency. In other words, with elevated CO2, photosynthesis rates are not as hampered as […]

“[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 […]
