Study: CO2 Causes Much Less Warming Than Hysterics Believe

"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."

"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."

"The inconvenient idea that CO2 ‘saturates’ above certain atmospheric levels, possibly at levels lower than current concentrations, has long been dismissed, but it does have the advantage of explaining the higher gas levels seen in the past. Carbon dioxide only absorbs heat in narrow bands on the infrared spectrum and it commonly overlaps with other warming gases such as ubiquitous water vapour. “The water vapour and CO2 overlapping at an absorbing band prevents absorption by additional CO2,” observe the authors. The water vapour usually damps the doubled CO2 forcing by reducing the energy additional CO2 can absorb, they add."

"Despite all this, a majority of science papers preach climate doomsday scenarios using RCP 8.5 ‘pathway’ modelled data that suggests the global temperature will rise by up to 4°C within less than 80 years. Other activists use computer models to claim that they can attribute single bad weather events to long-term changes in the climate."

Study by whom and who peer reviewed it?
Meanwhile it's the middle of winter and it should be snowing, I'm just walking home after work, bit of drizzle, quite warm. Should be snowing at this time of year, but isn't anywhere near cold enough.

And local places which have never flooded ever are on flood alert.
