Information - CL016 Deep Time Perspectives on Climate Change: Marrying the Signal from Computer Models & Biological Proxies
Scenarios for future climate change indicate that within the next 100-400 years, global annual average surface temperatures will increase by more than 6 degrees celcius (Intergovernmental Panel on Climate Change, 2001). This magnitude of warming has not been experienced for millions of years. There is a clear need to understand deep time (pre-Quaternary) climates if we are to predict the effects of future global warming on the Earth System and on the Earths biota, which includes us.
The basic themes to run through the session are: (a) how does the fossil record reflect climatic events and; (b) what can past climate and biotic events teach us about future changes in the Earth System. Within the session we would like to showcase the main microfossil and geochemical proxies used in the reconstruction of deep-time climates, and their use in advanced computer-based General Circulation Models. We would welcome any submissions which address the major events of Phanerozoic climate change, particularly those that demonstrate a link between data and modelling in one or more of the following areas:
1) Ancient climates - Snowball Earth to Permian deserts
2) Mesozoic climates - Greenhouse worlds
3) Early Cenozoic climates - Slipping into an Icehouse World
4) Late Cenozoic climates - Icehouse Worlds: growth of the polar ice sheets
The session has secured limited funding from the Scientific Committee on Antarctic Research Programme ACE (Antarctic Climate Evolution) to support polar and polar related submissions. We are currently seeking further funding. For more information please contact the session conveners.
This session is also an opportunity to showcase contributions to a new joint TMS/Geological Society of London book of the same name as this session, but is in no way restricted to authors who are contributing to the book.
