Carbon Dioxide Causes Much Less Warming Than is Commonly Believed, New Paper Finds

Chris Morrison of the Daily Sceptic: Three scientists, including Atmospheric Professor Yi Huang of McGill University, have reduced by nearly 40% the basic amount of warming caused by a doubling of atmospheric carbon dioxide – a figure commonly used to promote the global warming scare. In addition they cast doubt on the ability of CO2 to heat the atmosphere beyond the levels already passed in the pre-industrial age. “Transmissivity in the CO2 band centre is unchanged by increased CO2 as the absorption is already saturated,” they note…It is published by the American Meteorological Society in its Journal of Climate.

Another sensational finding is that higher levels of CO2 seem to actually cool Antarctica. “The [doubled CO2] forcing in polar regions is strongly hemispheric asymmetric and is negative in the Antarctic,” write the scientists.

The main paper is behind a paywall but an excellent summary of its contents is provided by the science blog No Tricks Zone. The science is complex with the ‘Abstract’ explaining that the paper evaluates the “spatiotemporal variation of the instantaneous, longwave CO2 radiative forcing at both the TOA [top of the atmosphere] and surface”. In plain terms, the work investigates the rise in temperature at three levels in the atmosphere as the Earth adjusts its thermal balance from heat trapped by so-called ‘greenhouse’ gases. Using a watts per square metre formulation (3.7 W/m2), it is commonly held by the Intergovernmental Panel on Climate Change that a doubling of CO2 will lead to a rise in temperature at the TOA of 1.2°C. The scientists have reduced this number to 2.26 W/m2, a 39% reduction down to a temperature rise of 0.72°C. At the surface, the rise is only 0.55°C. Large parts of the globe are measured at 0 W/m2 including below zero for Antarctica.

Study: ‘Global greening is an indisputable fact…the rate of global greening increased’ from 2001-2020 – Published in journal Global Ecology & Conservation

  https://www.sciencedirect.com/science/article/pii/S2351989423004262 Global Ecology and Conservation Volume 49, January 2024, e02791 Highlights • The global greening is an indisputable fact. • The rate of global greening increased slightly. • The drought has only slowed the global greening, but not caused the global browning. Abstract Increases or decreases in remote sensing-based vegetation greenness are usually referred to […]

New modeling study suggests plants might be able to absorb more CO2 from human activities than previously expected – ‘Paints an uncharacteristically upbeat picture for the planet’ – Published in journal Science Advances

https://phys.org/news/2023-11-absorb-co2-human-previously.html by Trinity College Dublin New research published in Science Advances paints an uncharacteristically upbeat picture for the planet. This is because more realistic ecological modeling suggests the world’s plants may be able to take up more atmospheric CO2 from human activities than previously predicted. … Simply planting more trees and protecting existing vegetation is […]

John Kerry wants you dead!? Watch: Kerry in 2021: ‘Even if we get to Net Zero, we still have to get carbon dioxide out of the atmosphere’

JOHN KERRY in 2021: “Even if we get to Net Zero, we still have to get carbon dioxide out of the atmosphere.” – JOHN KERRY, SPECIAL PRESIDENTIAL ENVOY FOR CLIMATE REMARKS on APRIL 22, 2021


Reality Check to Kerry’s anti-human rant: Washington State University report: “What is CO2? CO2 is a natural component of the atmosphere…CO2 is produced when people breathe. Each exhaled breath by an average adult contains 35,000 to 50,000 parts per million (ppm) of CO2 – 100 times higher than is typically found in the outside air (OSA).”

The Greening of the Globe: Global plant life surging

Here we present a global, measurement-based estimate of GPP growth during the twentieth century that is based on long-term atmospheric carbonyl sulfide (COS) records, derived from ice-core, firn and ambient air samples5. We interpret these records using a model […]
