If polar bears were threatened by warm temperatures

...they should already be dead.

Dr. Syun-Ichi Akasofu of the University of Alaska, Fairbanks published this chart along with his analysis of Arctic temperatures of the past several centuries.

Two things leap off the page:
  • the cycles of temperature are more extreme among the weather stations that ring the Arctic Ocean than among the more urban stations that support the IPCC's conclusions
  • the jump from 1920 to 1940, during a time when industrial CO2 emissions were falling (there was a depression on, remember?) took temperatures to a point higher than they are today.
How inconvenient. We have been here before, CO2 didn't cause it, and the polar bears survived. Over to you, Dr. Suzuki.
