Comment on the Announced Death of Stationarity

摘要

Milly et al. (2008) have announced the death of stationarity and state that stationarity can never be revived. The cause of death is given as anthropogenically induced changes in climate, the effects of which can not be undone, even with concerted effort directed to that effect. To contend with a nonstationary hydrology, Milly et al. state that an effort as focused as the Harvard Water Resources Program (1955-1960) may be necessary. These claims are questioned, whether stationarity is indeed dead or now has only secondary status.
