Regarding global warming, in a recent post I discussed how the temperature increase in the nineteenth century was about 1 degree Fahrenheit and the increase in the twentieth century was about 1.1 degree Fahrenheit. The GCM folks have assumed that the increse in the twentieth century was caused by increasing carbon dioxide concentration in the atmosphere. The models were "tuned" with this assumption. Thus it is a self-fulfilling prophesy that the GCM's predict dramatically increasing temperature with increasing carbon dioxide. In order for this position to be justifiable, it was necessary for there to have been a constant temperature for centuries prior to the twentieth, and for the carbon dioxide concentration to have been stable in the past. Regarding temperature, it was necessary to somehow get rid of the the medieval warm period, and the little ice age since no one knows what caused those temperature variations in the past. This was done with the temperature history "hockey stick" curve of Mann, et al. This analysis has been discredited as has been widely discussed. Regarding carbon dioxide, the IPCC relied on ice core samples that showed a carbon dioxide concentration of about 280 ppm. Thousands of direct measurements made in the nineteenth century were ignored. This situation needs to be resolved. The true believers in the Global Warming dogma are undeterred by the crumbling of the underpinnings of the carbon dioxide as the casue of global warming and the end of life as we know it.

In a related development, Dr. Zichichi, the President of the World Federation of Scientists , in a meeting at the Vatican said that the GCM's are "incoherent and invalid from a scientific point of view." He estimates that only about 10% of the recent warming has been due to man's activities.
