Global Warming Science A scientific foundation of anthropogenic climate change and an intro to climate models. Fundamental physical processes that shape climate (e.g. solar variability, orbital mechanics, greenhouse gases, atmospheric and oceanic circulation, and volcanic and soil aerosols) and on evidence for past and present climate change. Material consequences of climate change, including sea level change, variations in precipitation, vegetation, storminess, and the incidence of disease are discussed. The science behind mitigation and adaptation proposals. mit.edu/courses/earth-atmospheric-and-planetary-sciences/12-340-global-warming-science
