Physicists' Lab Experiment Shows A CO2 Increase From 0.04% To 100% Leads To No Observable Warming

Physicists’ Lab Experiment Shows A CO2 Increase From 0.04% To 100% Leads To No Observable Warming

Share this…FacebookTwitterTwo University of Oslo physicists designed several variations of a tabletop experiment trying to confirm the IPCC’s claimed CO2-forcing capacity. Instead they found (a) 100% (1,000,000 ppm) CO2 “heats” air to about the same temperature that non-greenhouse gases (N2, O2 [air], Ar) do, and (b) no significant temperature difference in containers with 0.04% vs. […]

Molecular Physicist's New Publications Add To The List of Over 130 Low CO2 Climate Sensitivity Papers

Molecular Physicist’s New Publications Add To The List of Over 130 Low CO2 Climate Sensitivity Papers

Share this…FacebookTwitterSeveral more estimates of extremely low CO2 climate sensitivity have been added to the database in the last year. The collection of scientific papers that assess a very low (under 1°C for a doubling of CO2) or a non-quantified, but negligible climate sensitivity has swelled to over 130. In 2015, when it was first published, […]

Share this…FacebookTwitter In 2020, more than 400 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. Over 400 scientific papers […]

2020 Review: Observational And Modeling Studies Show Temperature Falls As CO2 Rises

2020 Review: Observational And Modeling Studies Show Temperature Falls As CO2 Rises

Share this...

Share this…FacebookTwitterA 2020 observational study (Zhang et al., 2020) determined “temperatures of atmospheric air with substantially higher CO2 concentration (ranging from 3200 ppm to 16,900 ppm) were lower than that with the lower CO2 concentration (480 ppm)” and a 2020 modeling study (Drotos et al., 2020) assessed that when CO2 goes beyond 4 times preindustrial […]

Real-World Outdoor Experiment: As CO2 Naturally Rises From 0.1% To 75%, Surface Temperatures Drop 10°C

Real-World Outdoor Experiment: As CO2 Naturally Rises From 0.1% To 75%, Surface Temperatures Drop 10°C

Share this…FacebookTwitterAt an outdoor test site in Italy CO2 concentrations vacillating between 1,000 and 750,000 ppm have no more or less an effect on local temperatures than a nearby site with stable, ambient (<400 ppm) CO2 concentrations. Mofette fields are “natural carbon dioxide springs” that allow us to observe the effect that a 100% (1,000,000 […]

A New Experiment Finds Just A 1.3°C Temperature Differential For Contained Air With 0.05% Versus 100% CO2

A New Experiment Finds Just A 1.3°C Temperature Differential For Contained Air With 0.05% Versus 100% CO2

Share this…FacebookTwitterA new balloon experiment (inadvertently) demonstrates just how weak and inconsequential CO2’s warming effect is. Levendis et al. (2020) tried using an experiment with air-filled (99% nitrogen and oxygen) versus CO2-filled (100% CO2) balloons to demonstrate a consequential warming effect for CO2. But their study may have demonstrated the opposite. In the experiment a […]

Share this…FacebookTwitterScientists report they must “exclude atmospheric pCO2 as a direct driver of SST variations” after finding the Atlantic Ocean’s surface was multiple degrees warmer than today from 90 to 20 thousand years ago, or when CO2 concentrations hovered below 200 ppm.  Another new study (Hou et al., 2020) casts even more doubt on the […]

Model Failure: ‘All Model Runs Warmed Faster Than Observations’ … CO2 Sensitivity Estimates ‘Unrealistically High’

Share this...

Share this…FacebookTwitterScientists continue to document severe discrepancies between climate modeling and observations in newly published scientific papers. 1. Models run too hot and yield “unrealistically high” estimates of the climate’s sensitivity to CO2 forcing. McKitrick and Christy, 2020 “All model runs warmed faster than observations in the lower troposphere and midtroposphere, in the tropics, and […]

MetOffice, IPCC Climate Scientist Prof. Richard Betts Misunderstood Science Behind Drying Forests

Share this...

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

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

Share this...

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 […]
