Read here. A critical climate forcing, atmospheric aerosols, is analyzed by six NASA researchers using satellite technology. Aerosols have huge impact on climate, from absorbing energy to reflecting sunlight. For climate models to function as planned, it necessitates a full understanding of aerosols interactions. The researchers found the following, which indicates a major climate model and assessment weakness:
"because of the global nature of aerosol climate forcings, satellite observations have been and will be an indispensable [our italics] source of information about aerosol characteristics for use in various assessments of climate and climate change,"...."our new results suggest that the current knowledge of the global distribution of the AOT [aerosol optical thickness] and, especially, aerosol microphysical characteristics remains unsatisfactory."
