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 […]

Share this…FacebookTwitterAccording to a new paper, the Earth’s ocean heat content time derivative (OHCTD) has been decreasing (-0.26 W/m²/decade) since 2000, coinciding with a similar deficit in the Earth’s energy imbalance (EEI). The authors acknowledge such trends are “surprising” considering greenhouse gas emissions have risen. Image Source: Dewitte et al., 2019 Earth’s energy budget imbalanced? […]

Share this…FacebookTwitterCO2 concentrations rose from 345 ppm to 398 ppm in the 29 years from 1985 to 2014. Mainstream scientists sympathetic to the anthropogenic global warming (AGW) paradigm have nonetheless reported the overall greenhouse effect forcing has been flat to declining throughout this period. 1. Cess and Udelhofen, 2003 Due to the downward trend in […]

Share this…FacebookTwitterFor CO2 to be considered a driver of Earth’s temperatures, changes in CO2 that uni-directionally correlate with temperatures should not be an exceptional occurrence. Yet a causal link from CO2 radiative forcing to temperature changes could hypothetically be inferred for just 2.6% of the last 425 million years. A detailed analysis (Davis, 2017) of […]

Share this…FacebookTwitter Within the last few years, over 50 papers have been added to our compilation of scientific studies that find the climate’s sensitivity to doubled CO2 (280 ppm to 560 ppm) ranges from <0 to 1°C. When no quantification is provided, words like “negligible” are used to describe CO2’s effect on the climate. The […]

Share this… Facebook Twitter It’s been acknowledged by mainstream scientists for years now that at certain locations on planet Earth, rising carbon dioxide levels cause cooling. It’s now been determined that rising CO2 also causes “negligible” cooling (or warming) depending on the season. A few years ago a seminal paper (Schmithüsen et al., 2015) was […]

Share this… Facebook Twitter CO2 concentrations have risen from 310 ppm to 410 ppm since the 1930s. However, there has been no net change in Arctic or Greenland temperatures during these last 90 years. During the Pliocene, CO2 also ranged between about 300-400 ppm, but the Arctic was 15-22°C warmer and sea levels 25 meters […]
