So if the models are so hopelessly riddled with errors and uncertainty that an anthropogenic radiative forcing signal cannot be distinguished from noise, or if the total magnitude of the warming attributed to humans is one-tenth to one-hundredth of the error or uncertainty ranges, why are those who dare question the degree to which humans affect the Earth’s climate branded as “deniers” of science?

Talking Points for Discerning Pupils Faced with CO2 Alarmism in the Classroom

One of the ways in which the facile alarmism about CO2 being pushed at and within schools can be undermined is for the more able pupils to raise discussion points during classes.  A recent article in the Canada Free Press site gives a few good questions which look well worth trying.  See the original article here to get background and backup on each of the questions. (hat tip:

How do you explain that global temperatures according to UN data have not increased since 1998 and there has been no significant warming since 1995?


Are you aware that even the UN IPCC does not consider climate models to be “predictions” or “forecasts” but merely emission scenarios?

Are you aware of multiple scientific studies showing the medieval warm period (before SUV’s and human emissions) to be warmer than current temps?

How do you explain that CO2 levels have been much higher in the Earth’s history, but have not coincided with human or animal extinction?

Can you explain why Greenland has cooled since the late 1930’s and 1940’s?

Can you explain why Antarctic sea ice has expanded to record levels in recent years?

Are you aware that Arctic Sea ice has EXPANDED in 2008?

Are you aware of the multiple peer-reviewed studies blaming Arctic sea ice reductions on many factors not related to man-made carbon emissions?

Are you aware that the Earth is currently in one of the coolest periods in its geologic history?

Are you aware that a recent U.S. Senate report features more than 500 scientists dissenting from man-made climate fears—more than 10 times the number (52) of UN IPCC scientists who signed off on alarmist (and media hyped) Summary for PolicyMakers in 2007.

Are you aware that many solar scientists and geologists are now warning of a possible coming global cooling? 


How do you explain that an analysis in peer-reviewed journal found COLD PERIODS – not warm periods [..were associated with the greatest climate-related disasters such as major floods, and droughts] ?

How do you explain the recent U.S. government report which found Hurricanes declining, NO increases in drought, tornados, thunderstorms, heat-waves? 



  1. "How do you explain the recent U.S. government report which found "

    To which the natural response would be "which report?"

  2. I agree, Sleepalot - those extracts are pretty brief. To save you some time hunting through the source article, the relevant CCSP report is here as a pdf:
