Further holes have been blown in the settled scientific view that humans are responsible for all or most of the changes in the climate by burning hydrocarbons. 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. If correct, of course, this work destroys the settled climate science that back the collectivist Net Zero project. The findings are likely to be ignored by the mainstream media.
