The University of Texas Institute for Geophysics (UTIG) conducts research to advance our understanding of past and present climate change and to improve our ability to accurately model future climate change. We use paleoclimate reconstructions using corals, speleothems (cave deposits), and marine sediment cores to inform us about how climate changed in the past. We calibrate our proxies against the instrumental record, and we employ rigorous statistics to these calibrations and to the reconstructions in order to support our use of the proxies and archives as recorders of past climate. Lastly, our group here at UTIG has a unique mixture of modern climate and paleoclimate specialists who work together to perform powerful climate model-paleodata comparisons.
