Dr Stephen Grimes of Plymouth University, who initiated the research project, highlighted the climate changes that must have caused this increase in sediment erosion and transport — «We have climate model simulations of the effect of warming on rainfall during the PETM event, and they show some changes in the average amounts of rainfall, but the largest change is how this rainfall is packaged up — it's concentrated in more rapid, extreme events — larger and bigger storms.»

However, satellite observations are notably cooler in the lower troposphere than predicted by climate models, and the research team in their paper acknowledge this, remarking: «One area of concern is that on average... simulations underestimate the observed lower stratospheric cooling and overestimate tropospheric warming... These differences must be due to some combination of errors in model forcings, model response errors, residual observational inhomogeneities, and an unusual manifestation of natural internal variability in the observations.»
