Aerosols & Anthropogenic Global Warming
Paper in Science Magazine finally addresses the atmospheric aerosol problem in global warming, GW. It's been known for a long time that the predictions made by the GW alarmists are based solely on computer models and not on any reliable scientific data. This is the primary reason I'm a semi=proud AGW skeptic. Not "denier". Skeptic. These computer models do not include parameters like aerosols (dust and large molecules) and cloud formation and have minimal sun effects.
According to the authors, "Climate model projections neglecting these changes would continue to overestimate the radiative forcing and global warming in coming decades if these aerosols remain present at current values or increase."
So, paraphrasing, the computer models have been and will continue to exaggerate any AGW effects because they simply do not include enough parameters. Climate change, yes, climate changes, is so complex it simply cannot be accounted for yet. Paper is a nice read if you want your head to hurt.
