You are all describing weather, not climate. Temperatures in one city are irrelevant (so my initial response comparing 2011 and 2012--which were much hotter in Oklahoma--was also not relevant). It is also impossible to average the temperature of the earth. We set new record highs somewhere every year, and new record lows. If CO2 was causing warming, there would be observable evidence of that, but there is not. If you disagree, please show me the evidence that does not include computer models (gigo).
