Share this…FacebookTwitterJust recently Anthony Watts posted an article on wildfires penned by Paul Homewood. Lately alarmists have been blaming the active forest fire season on global warming. They warn that warmer temperatures will lead to more wildfires. Is it so? First it’s important to note that warmer temperatures don’t necessarily lead to more drought and […]

Share this…FacebookTwitterEvidence that temperature swings of ±17°C occurred during the end-Triassic mass extinction event imply that CO2 would have needed to increase 8- to 1,024-fold (3 to 10 doublings) to have induced that magnitude of temperature change. It didn’t. Evidence from a new study (Petryshyn et al., 2020) suggests “repeated” temperature swings of 16-17°C occurred […]

Share this…FacebookTwitterIn an interview with flagship daily Frankfurter Allgemeine Zeitung (FAZ here), Max-Planck Institute for Meteorology (MPIM) Director Dr. Jochen Marotzke said predicting how many degrees of warming we need to prepare for was like reading tea leaves and that he is not worried about “climate tipping points”. He also spoke of the wide disagreement […]

Share this…FacebookTwitterA commentary titled “‘Just don’t panic – also about climate change’” by Prof. Fritz Vahrenholt appearing at German site achgut.com tells us there’s no need for panic with respect to climate change, as leading scientists dial back earlier doomsday projections. Prof. Fritz Vahrenholt. Image: GWPF No warming until 2050 Vahrenholt claims a negative Atlantic […]

Share this…FacebookTwitterIn a new paper, atmospheric physicist Dr. Richard Lindzen summarizes the “implausible” claims today’s proponents of dangerous anthropogenic global warming espouse. Dr. Richard Lindzen retired several years ago, and yet his immense contribution to the atmospheric sciences lives on. His research is still cited about 600 times per year. Lindzen recently published another scientific […]

Share this…FacebookTwitter The radiative impact of CO2 on the ocean’s thermal skin layer cannot penetrate deeper than 0.01 mm. This effectively eliminates the potential for CO2 to be a driver of global warming. According to mainstream anthropogenic global warming (AGW) science, 93% of global warming is manifested in the 0-2000 m oceans. Just 1% of global […]

Share this…FacebookTwitterClouds regulate Earth’s climate. New studies suggest uncertainty in clouds’ surface radiative effects reach 17.4 W/m² per year (±8.7 W/m²/year). Total CO2 climate forcing is said to be just 0.02 W/m² per year. The difference in these magnitudes preclude detection of a CO2 signal in climate forcing. According to Feldman et al. (2015), a […]

Share this…FacebookTwitterIn yet another new paper (Drotos et al., 2020), scientists determine the climate sensitivity to CO2 is “practically zero” the more the concentration rises. A ~4450 ppm CO2 concentration has cooler climates than observed in the pre-industrial (278 ppm) era. Why? A self-amplifying cloud feedback mechanism cools the Earth by magnitudes “as large as […]

Share this…FacebookTwitterAn observational study analyzing the effects of 300, 480, 3200, 7500, and 16,900 ppm CO2 on atmospheric (and soil) temperatures has determined “temperatures of atmospheric air in mesocosms [controlled outdoor experiments] with substantially higher CO2 concentration (ranging from 3200 ppm to 16900 ppm) were lower than that with the lower CO2 concentration (480 ppm)”.

Share this…FacebookTwitterA new study (Stallinga, 2020) assesses the climate sensitivity to rising CO2 concentrations is just 0.0014°C per ppm. Dr. Peter Stallinga has published a comprehensive analysis of the Earth’s greenhouse effect. He finds an inconsequential role for CO2. Doubling CO2 from 350 to 700 ppm yields a warming of less than 0.5°C (500 mK). […]

Share this…FacebookTwitterIn 2019, more than 440 scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources.

Share this…FacebookTwitterAnother study finds CO2’s greenhouse effect contribution and climate sensitivity are much smaller than claimed by the IPCC and proponents of anthropogenic global warming. Ollila (2019) reconfigures the “consensus”-derived greenhouse effect radiation values and finds (a) LW absorption only adds 45% to Earth’s present atmospheric greenhouse effect, (b) water vapor dominates (76.4%) the total […]
