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 […]

New Study Finds Weak CO2-Induced Warming An 'Implausible' Explanation For The End-Triassic Mass Extinction

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 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 […]

Uncertainty In Natural Climate Forcing Is 870 Times Larger Than CO2 Forcing - A CO2 Signal Is Thus Not Detectable

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 […]

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). […]
