New Study: 21st Century Precipitation Trends Have Become Less Intense Globally

Yet another instance of the models getting it wrong.

 

Hydrological processes were expected to intensify with warming. The opposite has happened.

Per a new study, global precipitation intensity, measured in mm/hour per century, has exhibited flat (large precipitation systems) to declining (medium and small systems) trends from 2001 to 2020.

The de-intensification of the hydrological cycle has also been documented for the second half of the 20th century.

The highest frequency of global-scale extreme rainfall events occurred from 1960-1980 − when there were concerns about cooling.

Since then, the frequency and intensity of rainfall events have “decreased remarkably” (Koutsoyiannis, 2020).
