If there is any place on earth that is a natural control for the impact of increasing atmospheric CO2 it is Antarctica. Antarctica’s average winter temperature is -60 degrees Celsius which is close to the peak absorption of CO2 of -80 degree Celsius. Most importantly however is that the Antarctica air is very dry, so there is no impact from water vapor. The only significant GHG in the South Pole Troposphere is CO2.

1. Satellite measurements show no South Pole warming over the past 36 years. During this time CO2 increased from 330 ppm to 404 ppm.
2. Ground measurements show no South Pole warming over the past 59 years. During that time CO2 increased from 315 ppm to 405 ppm.
3. Increasing CO2 nearly 30% had no impact on temperatures in the region most likely to be impacted in an increase if CO2.
