 Such differences allowed a series of positive climatic feedbacks to occur sequentially and remain sustainable.Feedback mechanisms include topographically-induced monsoon, monsoon-intensified erosion, and erosional-driven uplift (isostatic rebound).Although the discussion of this model is limited to 20 Ma onwards, such concept can be implemented to future studies focusing on the Tertiary period so as to better understand how Tibet and the South Asian mosoon co-evolved.
