The Conclusion Humans Drive Atmospheric CO2 Increases Is Undermined By Carbon Isotope Data

“From modern instrumental carbon isotopic data of the last 40 years, no signs of human (fossil fuel) CO2 emissions can be discerned.” – Koutsoyiannis, 2024 It is routinely claimed that a telltale sign human emissions (fossil fuels) have irrevocably altered the atmospheric CO2 concentration is a declining trend in carbon isotope 13 (δ13C), considered an […]

The Effect Of CO2 Increases On Ocean Temperatures Is Too Small To Measurably Detect

The Effect Of CO2 Increases On Ocean Temperatures Is Too Small To Measurably Detect

The shallowest sea surface temperature measurement limit is 10,000 times deeper than the extent of CO2’s radiative influence. When sea surface temperatures (SSTs) are measured, the depth range of the measurement typically extends from 10 cm to 10 m, or 100 mm to 10,000 mm (Merchant et al., 2019). Image Source: Merchant et al., 2019 […]

New Study Concludes ‘CO2 Can Have No Measurable Effect On Ocean Temperatures’

“There can be no climate equilibrium state that can be perturbed by an increase in the atmospheric concentration of CO2…” – Clark, 2023 The anthropogenic global warming paradigm has a magnitude problem – especially when it comes to the assumption that we humans can warm the ocean with our CO2 emissions. New research suggests the […]

New Journal of Climate Study Reduces Doubled CO2 Climate Sensitivity By 40%, To 0.72°C

Doubling the 2005 CO2 concentration (380 ppm) to 760 ppm only produces a globally-averaged 2.26 W/m² perturbation at the top of the atmosphere (TOA). This doubled-CO2 forcing is close to 0 W/m² for large portions of the globe – including below 0 W/m² for Antarctica. The IPCC claims doubling CO2 produces a 3.7 W/m² TOA […]

Nearly 160 Scientific Papers Detail The Minuscule Effect CO2 Has On Earth’s Temperature

We have updated our “Extremely Low CO2 Climate Sensitivity” scientific paper list with new papers added from 2022 and 2023 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 8 years the list has grown to […]

New Research Says Doubling CO2 Leads To A 'Sometimes' Negative Greenhouse Effect

New Research Says Doubling CO2 Leads To A ‘Sometimes’ Negative Greenhouse Effect

“Negative TOA [top of atmosphere] forcing of CO2 increase also happens outside of Antarctica. The Arctic sometimes exhibits strong negative CO2 forcing. This phenomenon even occurs in the tropics and mid-latitudes…” – Chen et al., 2024 It has previously been reported that as CO2 increases from 380 ppm to 1000 ppm, the CO2 greenhouse effect […]

New Study Finds No Evidence Of A CO2-Driven Warming Signal In 60 Years Of IR Flux Data

New Study Finds No Evidence Of A CO2-Driven Warming Signal In 60 Years Of IR Flux Data

“The real atmosphere does not follow the GHG [greenhouse gas] GE [greenhouse effect] hypothesis of the IPCC.” – Miskolczi, 2023 CO2 increased from 310 ppm to 385 ppm (24%) during the 60 years from 1948 to 2008. Observations indicate this led to a negative radiative imbalance of -0.75 W/m². In other words, increasing CO2 delivered […]

New Study Now Claims We Humans Heat The Atmosphere Just By Exhaling

New Study Now Claims We Humans Heat The Atmosphere Just By Exhaling

“Where hydrocarbon chains (food types) are consumed by humans and turned into CH4 [methane] … global warming potential is no longer neutral, and human respiration has a net warming effect on the atmosphere.”  – Prada et al., 2023 Image Source pexels.com (stock photo) According to a new study, humans “contribute to global warming” by exhaling […]

Another Day, Another Scientific Paper Insists 'Global Warming Is Not Caused By Increased CO2'

Another Day, Another Scientific Paper Insists ‘Global Warming Is Not Caused By Increased CO2’

“…the rate of change in CO2 concentration is controlled, not by emissions, but by the global temperature” – Emrén, 2023 A new study published in the International Journal of Global Warming once again questions the popular narrative that says humans can control the temperatures of the ocean and melt the polar ice sheets by engaging […]

New Study Finds The Post-1900 CO2 Rise Has Not Discernibly Altered The Greenhouse Effect

New Study Finds The Post-1900 CO2 Rise Has Not Discernibly Altered The Greenhouse Effect

Variations in the greenhouse effect are predominantly modulated by water vapor and cloud cover. CO2’s role in the greenhouse effect is so minor it cannot be discerned. For decades scientists have reported that a CO2 concentration of about 300 ppm can only increase the downwelling longwave radiation (DLWR), or greenhouse effect, by about 1.5 W/m² […]

New Study: CO2 Emission Rates From Natural Sources Are Up To 6 Times Larger Than From Humans

New Study: CO2 Emission Rates From Natural Sources Are Up To 6 Times Larger Than From Humans

Analysis of CO2 residence times suggest 65% to 96.5% of the CO2 concentration increase since 1958 is natural. According to a new study, the claim that increases in atmospheric CO2 are driven exclusively by humans relies on a made-up, disparate accounting model, with the residence time for natural emissions 3 to 4 years (which is […]

A 'Major Surprise' Nature Study Finds Phasing Out Fossil Fuels Will Lead To Decades Of Warming

A ‘Major Surprise’ Nature Study Finds Phasing Out Fossil Fuels Will Lead To Decades Of Warming

“We would expect from a 100% switchover from fossil fuels to zero-emission renewables…net radiative heating would increase drastically.” – Nair et al., 2023 Using observational data gleaned from COVID-19 lockdowns in South Asia, scientists publishing in a Nature journal (Nair et al., 2023) have now determined the ongoing switch to zero greenhouse gas (GHG) emissions […]
