Global climate shift in 1970s causes a significant worldwide increase in precipitation extremes

Abstract The shift in climate regimes around 1970s caused an overall enhancement of precipitation extremes across the globe with a specific spatial distribution pattern. We used gridded observational-reanalysis precipitation dataset and two important extreme precipitation measures, namely Annual Max...
