Read here. This lamebrain temperature graph was published in the 2007 IPCC report and the linked article explains its creation. The IPCC needed to convince the MSM that global temperatures were "accelerating" -- not a very difficult objective considering the low science IQ that MSM reporters and pundits represent. Needless to say, unprofessional behavior and a non-scientific, political agenda by IPCC representatives was the genesis. Surprised?
