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. Indeed, on past form some activist journalists and scientists may seek to get the paper retracted. For the time being, 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. None of this will be a surprise to regular readers since it would appear to be confirmed by observations that the region has shown “nearly non-existent warming” over the last 70 years. The recent “mind-blowing’” scare over low levels of winter sea ice has been debunked by evidence from early weather satellites showing similar levels in 1966.
