Climate “Science” on Trial; The Forensic Files: Exhibit F

Exhibit F: Antarctica isn’t warming

If there is anyplace 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 very very dry, so there is no impact from water vapor. The only significant GHG in the South Pole Troposphere is CO2.

Talking Points:

  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 by an increase if CO2.kc-monthly-0600
  4. The North Pole is not a “control” for CO2 because its temperature is largely influenced by ocean currents. BTW, an ice free North Pole is nothing new or anything to be alarmed about. The graphic is of the USS Skate SSN-578.pic-23-ssn-skate-5962-globa
  5. What efforts to prove Antarctica has been warming with the rest of the globe have failed. I personally find it odd that they try so hard to prove something instead of trying to understand why Antarctica isn’t warming. If CO2 was the cause it would be obvious.
  6. Antarctica has CO2 at 400 ppm but no atmospheric H2O. The reasons for the cold temperatures are widely known…largely there is no atmospheric H2O.
  7. This quote explains why the Arctic climate is different from the Antarcticthe Arctic is mainly ocean surrounded by land masses, whereas the land mass of Antarctica is surrounded by the Southern Ocean. Given the different heat capacities of land and sea (sea is much slower to both heat up and cool down), we would expect the coldest temperatures to occur at the pole that is dominated by land rather than sea.” In other words, the Arctic ice floats on water, and is greatly influenced by the temperature of the water. Warmer oceans will melt more Arctic ice. CO2 and LWIR between 13 and 18 microns won’t warm water, so the loss of Arctic ice is due to something other than CO2. Loss of Arctic ice isn’t evidence that CO2 is causing warming, loss of Antarctic ice would be. Antarctica has been gaining ice mass at a rate of 1.2% per year, or over 1,000,000 sq km/yr1,000,000 sq km/yr.s_plot_hires
  8. The recent dip in Antarctica sea ice appears to be an anomaly, and may be due to warmer oceans. Studies show Antarctic has been gaining ice while CO2 has been increasing for the past 100 years.csic_figure3
  9. NASA Study: ‘Antarctica is not currently contributing to sea level rise’ – ‘Mass Gains of Antarctic Ice Sheet Greater than Losses’ antarctic-ice
  10. Antarctica is an extremely cold location, and rarely if ever gets above freezing except for coastal areas which are warmed by the ocean currents bringing in heat. Ice won’t melt in sub zero temperatures, so what ice loss does occur is due to ocean warmth, not CO2 driven atmospheric warming. The oceans are warmed by incoming visible and UV radiation, not outgoing LWIR between 13 and 18 microns.
  11. The North Pole also rarely gets above freezing, so once again, any loss of sea ice is due to the oceans bringing in the extra energy, not the atmosphere. CO2 and LWIR between 13 and 18 microns won’t warm the oceans. Note the rapid increase in temperature over a matter of hours. No way can a constant level of CO2 cause such a rapid increase in temperature. The above freezing reading of the North Pole is rare enough that it makes the newspaper. imrsscreenhunter_249-aug-05-14-21
