Expected Temperatures - Calculation of
- The following is how I derived expected temperature based on CO2
concentration levels in the atmosphere (in my November 11, 2002 post to
I used existing graphs of CO2 and temperature over the last 160,000
calculated the average ratio between CO2 in PPM and Temperature in
over the last 160,000 years. The ratio I came up with in doing that was
that CO2 PPM is 16.6 times the temperature C in the atmosphere at any
particular time.. For a CO2 concentration equal to the measured level
of 375 PPM CO2, the global average temperature would be expected to reach
375/16.6 = 22.6 C (72 F) or 7.6 C (13 F) over the present global average
temperature of 15 C (59 F).
A doubling of the present CO2 concentration of the atmosphere of 375 PPM
750 PPM would result in an expected global average temperature of
45.1 C (113 F), or 30 C (54 F) rise in the global average temperature.
