Abstract

ORNL's Climate Change Science Institute will host a lecture by Benjamin D. Santer, an atmospheric scientist at Lawrence Livermore National Laboratory and member of the National Academy of Sciences, Monday, April 22, at 11 a.m. in the JICS Auditorium (Building 5100 Room 128).

The title of his talk is "A Life in Climate Science: From Identification of a 'Discernible Human Influence' on Climate to Identification of the 'Top Ten' Climate Models."

Santer's research focuses on evaluation of climate models, use of statistical methods in climate science, and identification of natural and human-caused "fingerprints" in observed climate records. His early research contributed to the historic conclusion, relayed in the 1995 assessment report of the Intergovernmental Panel on Climate Change (IPCC), that humans exert a discernible influence on climate.

Studies of the causes of climate change frequently rely on complex numerical models of the climate system. But not all models show equal skill in capturing key features of present-day climate. Santer's talk will explore if models with higher skill in reproducing today's climate should be regarded as more trustworthy predictors of 21st century climate change.
