Antarctica should be showing the greatest impact from CO2 because it is also extremely dry, therefore much less noise caused by water vapour. the fact that it seems like the main continent is cooling should be a stick in the spokes of the CO2 bandwagon.
Antarctica is showing the greatest impact from CO2....it is cooling....as I have pointed out repeatedly, CO2 is not a blanket...it is like holes in the blanket...sensitivity of zero or less.
I think you are foolish to believe that CO2 is causing Antarctica to cool.
