My USGS Science Strategy Areas

Climate Variability & Change

PRISM Group

PRISM is a collaborative data analysis and climate modeling effort that strives to:

1) accurately and comprehensively reconstruct and understand Pliocene climate and climate dynamics in order to gain insight into a warmer-than-present world that may resemble a future climate; 

2) to construct Pliocene paleoenvironmental/paleoclimatic boundary conditions as an aid to general circulation model experiments designed to explore the impacts of climate forcings and feedbacks.


The Pliocene world provides an unequalled paleo-laboratory to test the sensitivity of the physical models that we rely upon for estimating future warming impacts. It challenges our understanding of the sensitivity of key components of the climate system and how we simulate that system.
