Scientists: Only 10% Of The 1984-2017 Greenhouse Gas (Longwave) Forcing Was From CO2

Scientists: Only 10% Of The 1984-2017 Greenhouse Gas (Longwave) Forcing Was From CO2

Share this…FacebookTwitterA late 2021 study finds water vapor and temperature changes accounted for 90% of the changes in clear-sky downwelling longwave or greenhouse effect forcing since the mid-1980s. CO2 forcing assumed a mere bit-player role. The seminal Feldman et al. (2015) study concluded it takes 10 years and a 22 ppm increase in CO2 to […]

New Study Affirms Temperatures Determine Greenhouse Gas Forcing Trends, Not The Other Way Around

New Study Affirms Temperatures Determine Greenhouse Gas Forcing Trends, Not The Other Way Around

Share this…FacebookTwitterCO2 and water vapor greenhouse effect impacts are not independent climate forcings . A new study affirms the “variance in the radiance in these channels is primarily controlled by…temperature” and “atmospheric absorption is strongly saturated in these [CO2, water vapor] channels”. It has previously been established that greenhouse gas (water vapor, CO2) forcing “cannot […]

Glaring Inconsistency In Estimating CO2 vs. Solar Forcing Suggests CO2 Impacts Are Wildly Exaggerated

Glaring Inconsistency In Estimating CO2 vs. Solar Forcing Suggests CO2 Impacts Are Wildly Exaggerated

Share this…FacebookTwitterFrom about 11,000 to 9,000 years ago the summer solar irradiance absorbed by the Earth’s surface has been estimated to be 40-60 W/m² greater than today from latitudes 40°N to 70°N (Ullman et al., 2015). These values seriously undermine the claim CO2 is the driver of climate change. Image Source: Ullman et al., 2015 […]

German Physicist: Human CO2 Emissions Responsible For 0.05°C Of The Global Warming Since 1750

German Physicist: Human CO2 Emissions Responsible For 0.05°C Of The Global Warming Since 1750

Share this…FacebookTwitterProfessor Herman Harde, an environmental physicist, has authored a new position paper on the follies of assuming humans significantly impact the climate. As detailed in his 2017 paper, Dr. Harde concludes the “anthropogenic contribution to the actual CO2 concentration is found to be 4.3% [a figure derived from IPCC AR5], its fraction to the […]

Alarmists: Clouds May 'Disappear Forever' With Warming. Observations: Clouds Increase As It Warms.

Alarmists: Clouds May ‘Disappear Forever’ With Warming. Observations: Clouds Increase As It Warms.

Share this…FacebookTwitterA new study finds the modeling-based claim that cloud cover changes are only responding to anthropogenic CO2 forcing as a feedback – and not functioning independently as a forcing – has (again) been contradicted by observations. Since this is a water planet, and since clouds are formed when water vapor turns into water droplets, […]

The Evidence Keeps Piling Up: Iceland Is Not Cooperating With The ‘Global Warming’ Agenda

Share this…FacebookTwitterIf decadal- and century-scale glacier advance and retreat is strongly indicative of a region’s climate, glacier behavior in Iceland saps the narrative that says anthropogenic CO2 is a climate driver. Per a new study, many of the northern Icelandic glaciers in existence today had “disappeared” from about 10,000 to 6,000 years ago. At the […]

AR6 Model Failure Affirmed: 'No Model Group Succeeds Reproducing Observed Surface Warming Patterns'

AR6 Model Failure Affirmed: ‘No Model Group Succeeds Reproducing Observed Surface Warming Patterns’

Share this…FacebookTwitterA new study published in Geophysical Research Letters highlights the abysmal model performance manifested in the latest Intergovernmental Panel on Climate Change report (AR6). The 38 CMIP6 general circulation models (GCMs) fail to adequately simulate even the most recent (1980-2021) warming patterns over 60 to 81% of the Earth’s surface. Dr. Scafetta places particular […]

Atmospheric Physicist: CO2 Explains 0.1°C Of 1975-2000 Warming - 'One Fifth Of The IPCC Assumption'

Atmospheric Physicist: CO2 Explains 0.1°C Of 1975-2000 Warming – ‘One Fifth Of The IPCC Assumption’

Share this…FacebookTwitterA new study uses existing temperature and CO2 records and albedo/natural variability attribution to suggest most of the recent warming is natural. The climate sensitivity to CO2 forcing is just over 0.2°C for a 100 ppm concentration increase. Dr. Syun-Ichi Akasofu is an “expert in aurora physics, solar physics, geophysics, and magnetosphere” and the […]

New Study: The CO2-Drives-Global-Warming 'Concept' Is 'Obsolete And Incorrect'

New Study: The CO2-Drives-Global-Warming ‘Concept’ Is ‘Obsolete And Incorrect’

Share this…FacebookTwitter“The IPCC concept that increasing carbon dioxide in the atmosphere causes global warming is three decades out-of-date.”  − Lightfoot and Ratzer (2022), Journal of Basic & Applied Sciences In analyzing UAH global temperature and Mauna Loa CO2 records from 1979 to 2021, climate researchers Lightfoot and Ratzer (2022) report there has been “little, if […]

Hundreds More Papers Published In 2021 Support A Skeptical Position On Climate Alarm

Share this…FacebookTwitterIn 2021, several hundred more 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. These scientific papers affirm the […]

Nearly 140 Scientific Papers Detail The Minuscule Effect CO2 Has On Earth’s Temperature

Share this…FacebookTwitterWe have updated our “Extremely Low CO2 Climate Sensitivity” scientific paper list with new papers added from 2021 and some newly discovered papers from the past. As of 2016 this list had only 50 papers on it (as indicated by the web address). In less than 6 years the list has grown to 137 […]

2 More Studies: The Climate's CO2 Sensitivity Is Low...Models Erroneously Overestimate CO2 Warming

2 More Studies: The Climate’s CO2 Sensitivity Is Low…Models Erroneously Overestimate CO2 Warming

Share this…FacebookTwitterAstrophysicists conclude climate models are deeply flawed. Doubling CO2 to 560 ppm only elicits about 1°C warming. Dr. Frank Stefani is an astrophysicist who has published several recent papers (Stefani et al., 2016,  Stefani et al., 2017, Stefani et al., 2018, Stefani et al., 2019, Stefani et al., 2020) on the role of solar […]
