Global paleohydrological change

In studying the past, paleohydrologists employ synthetic reasoning, using retroductive (causal) inference, to interpret indices (signs) of ancient processes that reveal the natural patterns (habits) of Earth experience through time and space. Discovery of anomalous phenomena leads to the need for revising prior conceptualizations (models), reformulating them to be more in accord with reality. An example is the recent discovery in tropical river paleoflood records that large floods may be preferentially clustered in recent decades. If corroborated by further study, this may indicate an influence of global greenhouse warming on monsoonal circulation and tropical storms. Such change could have profound implications for global habitability. -from Author
