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 […]

“An increase in low cloud cover of only about 1% could largely compensate for the doubling of CO2.” – van Wijngaarden & Happer, 2025 Ph.D physicists detail just how insignificant CO2 is as a factor in climate change, revealing that doubling the CO2 concentration from 400 ppm to 800 ppm – a 100% increase – […]

The alarmist talking point insisting human CO2 emissions and “climate change” have been driving and will continue to drive the Earth’s 6th Mass Extinction event is not supported by the evidence. Twenty years ago it was claimed climate change (global warming) would drive the extinction of one million species by 2050. This presumes human-induced rates […]

Today, with CO2 levels supposedly in the “dangerously high” range, Central Greenland has 3 kilometers of ice piled atop it. Scientists have known since the GISP2 borehole was drilled in 1993 that Central Greenland deglaciated at least once in the late Pleistocene (Bierman et al., 2024). Indeed, the Summit of the modern Greenland ice sheet […]

The greening of the Earth’s vegetated areas is “attributed to CO2 fertilization, climate change, and land use changes.” New remote sensing research (Gutiérrez-Hernández and García, 2025) uses robust statistical methods to eliminate false positives and spurious correlations in establishing vegetation trends in the satellite era. The scientists find 38% of the Earth’s land surface has […]

Ice shelf collapse was much more pronounced and exceptional millennia ago than it has been over the last 47 years. The advent of post-1970s “climate change” and polar amplification due to the rapidly rising trend in human greenhouse gas emissions was supposed to unleash catastrophic ice calving losses and increases in iceberg size throughout the […]

The 2013-2022 warming trend and the extreme warmth in 2023 were “not associated with” declining outgoing longwave radiation induced by rising greenhouse gases. Instead, a new study published in the journal Science contends that decreasing cloud albedo and the consequent increase in ASR, or absorbed solar radiation (+0.97 to 1.10 W/m²/decade according to ERA5 and […]

The evidence that rising CO2 concentrations lead to inconsequential warming keeps piling up. In a new study, seven Viennese researchers provide more evidence the CO2 absorption band is already saturated at today’s concentrations (over 400 ppm). Rising CO2 levels thus cannot drive significant global warming. “Data from ground measurements indicate that the downward (backward) radiation […]

A new analysis indicates tripling the atmospheric CO2 concentration from 100 to 400 ppm only produces a 0.3°C surface warming effect. Eight engineers (Wei et al., 2024) from the National Sun Yat-Sen University in Taiwan have assessed the capacity of rising CO2 concentrations to affect surface air temperature (SAT) over a 5-year research observation period. […]

Cost-benefit analyses affirm it would be better to abandon Net Zero policy initiatives and instead “do nothing” about greenhouse gas emissions. New research finds CO2’s largest possible climate impact is “negligible.” The cumulative expected temperature change in doubling CO2 from 400 to 800 ppm is only 0.81°C at most, and this is “certainly not cause […]

Paleoclimate evidence affirms warmth reduces drought frequency and intensity. A new study utilizes Asian tree pollen records to affirm that for the last 8000 years centennial-scale warming periods were associated with reductions in drought, famines, crop failures. “…warm periods were associated with increased precipitation along with relatively short-lived drought events.” In contrast, centuries of cooling […]

Even though atmospheric CO2 rose from 337 ppm in 1979 to 420 ppm in 2022, there is no evidence of a warming trend across Antarctica during this period. According to a new study, Antarctica’s station data indicate a pronounced cooling trend by over -1°C (-0.53°C per decade) from 1979-1999. The cooling trend thereafter slowed to […]
