In 2007 the Intergovernmental Panel on Climate Change (IPCC) issued Assessment Report Four (AR4) which fails on one simple test – most of the climate models used in the analysis did not include carbonaceous aerosols. My analysis indicates about 75%!!
Therefore since the majority of the anthropogenic, continental scale, aerosol plumes shown in the NASA Terra data below contain significant levels of carbonaceous aerosols and some are nearly exclusively carbonaceous whatever was modeled for AR4 was not the climate as it existed at the time and beacause of this the conclusions in AR4 are at best questionable and at worst rubbish.
