Claim: Episodic and intense rain was caused by ‘ancient global warming’

by Anthony Watts, September 4, 2018 in WUWT


From the University of Bristol and the “models before measurements” department comes this highly speculative claim that is entirely based entirely on climate models. There’s no actual measured data from any sort of paleo research. It’s science, but not as we know it.


A new study by scientists at the University of Bristol has shown that ancient global warming was associated with intense rainfall events that had a profound impact on the land and coastal seas.

The Palaeocene-Eocene Thermal Maximum (PETM), which occurred about 56 Million years ago, is of great interest to climate scientists because it represents a relatively rapid global warming event, with some similarities to the human-induced warming of today.

Although there have been many investigations of how much the Earth warmed at the PETM, there have been relatively few studies of how that changed the hydrological cycle.
