"What on Earth do Jupiter, Mars, and Venus have to do with climate and carbon cycling?" at the ICTA-UAB María de Maeztu Seminar Series
Professor Richard E. Zeebe from the University of Hawaii will be visiting the ICTA-UAB next Thursday, April 20th, at 12 noon to give the seminar "What on Earth do Jupiter, Mars, and Venus have to do with climate and carbon cycling?". The lecture is part of the ICTA-UAB MdM Seminar Series.

In his presentation, Richard E. Zeebe will describe the basic physics behind, and new results of accurate solar system integrations for Earth's eccentricity over the past hundred million years. He will discuss various limitations within the framework of present simulations and compare the results to existing solutions. Furthermore, he will present new results from practical applications of such orbital solutions in paleoclimatology, including effects of orbital forcing on coupled climate- and carbon cycle variations. For instance, one of our recent studies revealed a mechanism for a large lag between changes in carbon isotope ratios and eccentricity at the 400,000-year period, which had been observed in Paleocene, Oligocene, and Miocene sections. Finally, he will present the first estimates of orbital-scale variations in atmospheric carbon dioxide during the early Paleogene.
Dr. Richard E. Zeebe is a faculty member at the University of Hawaii. His research focusses on the global carbon cycle, biogeochemistry, geology, paleoceanography, astrochronology and more. His interests range from the physico-chemical properties of molecules and the biogeochemistry of foraminifera to the scale of the global ocean and the solar system. Together with Wolf-Gladrow he published a book on the CO2 chemistry in seawater which has been referred to as the CO2 survival kit. Dr. Zeebe received a Ph.D. in Physics from the University of Bremen, Germany. He has served as editor of the journals Climate of the Past and Paleoceanography.
