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…FacebookTwitterA new analysis by Drs. Wijngaarden and Happer (2020) suggests the “self-interference” saturation of all greenhouse gases in the current atmosphere substantially reduces their climate forcing power. At the current concentrations, the forcing power for greenhouse gases like CO2 (~400 ppm) and CH4 (1.8 ppm) are already saturated. Therefore, even doubling the current greenhouse […]

Scientists (Wang et al., 2020) have determined stomatal evidence can uncover large short-term CO2 fluxes of 50-100 ppm within a century or less. Measurements from a forest near Mt. Kurikoma, Japan, reveal minimum to […]

Share this…FacebookTwitter The first-ever randomized controlled trial (4,862 participants) for mask-use effectiveness in the COVID-19 era reveals that people who wear face masks properly in public are infected only 0.1 of a percentage point less often (2.0% vs. 2.1%) than those who do not wear masks in public. In 2018 the United States’ Center for […]

Share this…FacebookTwitterReconstructions of past temperatures show much colder periods with higher CO2 levels or as-warm or warmer periods with much lower CO2 levels. A new study (Paus, 2020) indicates modern July temperatures center around 7.5 to 8°C in the Scandes Mountains (Norway). Today’s CO2 atmospheric concentration has reached 410 ppm. During the latter stages of […]

Share this…FacebookTwitterThe southwestern US was nearly a desert from about 9000 to 5000 years ago, when Holocene peaks in aridity, surface temperature, and wildfire rates occurred. Arctic sea ice was at its lowest extent of the Holocene during these years. Image Source: Lachniet et al., 2020 A new extensively-referenced study (Lachniet et al., 2020) reviewing […]

Share this…FacebookTwitterOnly a few thousand years ago, when CO2 levels were both stable and low (~265 ppm), the (1) Arctic had far less ice and more vegetation than it does now and (2) the massive rate of ice melt in Antarctica rendered modern melt rates negligible by comparison. A new study (Cherezova et al., 2020) […]

Share this…FacebookTwitterThe forcing uncertainties and lack of observational measurements in the top-to-bottom global ocean preclude an assessment that modern warmth is due to anthropogenic activities. Key points from a new paper (Gebbie, 2021): • 93% of the changes to the Earth’s energy budget, manifested as warming of the Earth system, are expressed in the global […]

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 […]

Share this…FacebookTwitterFor years scientists have been using biomarker evidence (IP25, PIP25) to reconstruct the Arctic’s sea ice history. The evidence shows modern (20th-21st century) Arctic sea ice is at its greatest extent since the Holocene began. Scientists (Wu et al., 2020) have determined that from about 14,000 to 8,000 years ago, when CO2 lingered near […]

Share this…FacebookTwitterIn a new study, scientists insist that since the Earth’s highest biomass and biodiversity exist in the warmest regions, “higher temperatures than currently existing on Earth” and a “higher water content (absolute humidity) in the atmosphere” seem to be “more favorable” to the planet’s inhabitants. Until a few thousand years ago, when mammoths and […]
