Milankovitch theory and monsoon

The widely accepted “Milankovitch theory†explains insolation-induced waxing and waning of the ice sheets and their effect on the global climate on orbital timescales. In the past half century, however, the theory has often come under scrutiny, especially regarding its “100-ka problem.†Anothe...
