[T]he AGWT [Anthropogenic Global Warming Theory] was globally advocated by the IPCC in 2001 because it appeared to be supported by the ‘infamous’ Hockey Stick temperature reconstructions by Mann et al. [10]* and by specific computer climate models mainly based on radiative forcings [4,11]. Those temperature reconstructions claimed that only a very modest change in the Northern Hemispheric climate had occurred during the pre-industrial times from A.D. 1000 to 1900, while an abrupt warming did occur just in the last century. Energy balance and general circulation climate models (GCM) were used to interpret the Hockey Stick climatic pattern as due mostly to anthropogenic greenhouse gas emissions such as CO2 because of coal and oil fuel consumption, which has been accelerating since the beginning of the 20th century [11].
