OMG...another trite comment!
This simply opens up the old "is man-made CO2 really having any effect on the climate?" debate. Did I not make the point that the temperature since 1750 (presumed approx. start of the industrial revolution) has only increased by around 1degC over 261 years? Look at the DATA. When the world mean temperature departs alarmingly from its slow long term climb (0.4degC per century) - well that will be the time to re-visit the radiative transfer HYPOTHESIS which, currently, remains dead in the water. In the meanwhile we should let the FACTS speak for themselves and stop spending taxpayers' money on expensive scams and boondoggles.
