Share this…FacebookTwitterIt has been assumed COVID lockdowns and their associated reductions in human CO2 emissions would be a “step in the right direction” with regard to climate change mitigation. But a new study finds the particulate (aerosol) pollution reductions from less industrial and transportation activity in Europe during the months of March to May (2020) […]

Share this…FacebookTwitterA French physicist recounts the evidence affirming temperature changes are the cause of changes in atmospheric CO2 concentrations throughout the last 423 thousand years of the ice core record, thus invalidating the claims of more than a negligible role for CO2 in affecting climate changes. In a new study Dr. Pascal Richet re-emphasizes the […]

Share this…FacebookTwitterA professor of hydrology from the University of Athens eviscerates the “naïve” paradigm that says the natural state of Earth’s climate is constancy and stability, only changing when an “external agent” (i.e., a rapid increase in fossil fuel emissions ) acts upon it. Instead, (a) water is the main element driving climate and (b) […]

Share this…FacebookTwitterA new CO2 climate sensitivity study suggests that, beyond the 300 ppm threshold, “any further increase of (anthropogenic) CO2 cannot lead to an appreciably stronger absorption of radiation, and consequently cannot affect the earth’s climate.” Dr. Schildknecht is a Bielefeld University physics professor affiliated with the Max Planck Institute in Munich. His equilibrium climate […]

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. […]

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 […]

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 […]

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 […]

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 […]

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 […]
