Session description: Past warm intervals may provide insight into climatic forcing in the absence of anthropogenic perturbations. Among the many past warm intervals, the Pliocene is of particular interest because continental configurations were very similar to modern configurations and CO2 concentrations appeared to be both comparable to present-day values and stable. These boundary conditions provide an ideal testbed for exploring feedback mechanisms that may have contributed to significantly warmer temperatures during the Pliocene and the subsequent cooling that lead to the obliquity-dominated climate regime of the Pleistocene. In this session we wish to combine model simulations with empirical estimates to better characterize the climate of the Pliocene. Temperature variability from the equator to the poles will be explored to identify spatial patterns of climate feedbacks or poleward heat transport as well as the persistence of regional climate oscillations during the Pliocene. This session will provide an opportunity to synthesize proxy data and compare results from different model simulations. We are also interested in better ways of quantifying Earth?s surface properties, including vegetation, ice cover, and sea level during this interval. In addition, we invite contributions that explore novel climate proxies and new estimates from conventional proxies during the Pliocene. Ultimately, the goal of this session is to foster a dialog between paleoclimatologists working in the terrestrial and marine realms as well as between those employing models and proxies to gain a better understanding of Earth?s climate system during the Pliocene.

Session description: Evolution of global ocean circulation and climate in the last 21,000 years exhibit dramatic changes and abrupt events such as the Last Glacial Maximum, the Heinrich Event 1, the Bolling-Allerod, the Younger Dryas, deglaciatioin and various stages of the Holocene. A better characterization and understanding of these major changes are critical for our assessment of potential future climate changes. This session will discuss the reconstruction and synthesis of the latest paleobservations on the evolution of global oceanic circulation and climate in this period as well as recent modeling activities. We especially encourage the participation of multi-proxy synthesis of the transition evolution of oceanic and climate events, meltwater amounts and locations, sea ice, ice sheet and terrestrial proxies, including millennial variability and abrupt climate changes.

Please also pass on to any interested parties. This is for Paleoclimatology and Paloceanography session PP25 (note that it is merged from PP05 and PP20).

Best regards, Rosanne D'Arrigo Rob WIlson Dave Anderson Ed Cook Pinxian Wang PP25: The Climate of the Monsoon: Proxy Records, Measurements and Models Description: Six monsoon systems are recognised in the modern world, the African, South Asian, East Asian, Australian, North American and South American, and future changes have the potential to affect billions of people. The regional monsoon systems are driven by the same annual cycle of solar heating, yet differ from each other in their geographic position and orographic features, and changes of the global monsoon are now studied as well as regional and local-scale monsoon climate. This session focuses on the large-scale regional to global changes in monsoons across recent and past timescales and on their underlying forcings and teleconnections. Contributions discussing evidence from high resolution proxy records (including tree rings, corals, ice cores, speleothems, sediment data), instrumental records and model simulations are welcome. The session is co-sponsored by PAGES through its new initiative on "Global Monsoon and Low-Latitude Processes: Evolution and Variability", and by the National Science Foundation Paleoclimate Program's Monsoon Asia Project. -- David M.

Session description: One of the values of paleoclimate reconstructions is that they provide scenarios different from today's climate, which can be used to validate climate models. This entails particularly high demands on the accuracy and resolution of records of past climate forcings. This session addresses the challenge to improve and extend time series of climate forcings and feedbacks, both natural and human-made, including solar insolation and irradiance intensity, volcanic activity, land use, and greenhouse gas and aerosol concentrations. Accurate reconstructions of the climate forcings allow climate system models to be used to quantify the sensitivity of the climate system, spatially and temporally, and to understand the natural, forced and unforced, variability of the climate system. It allows us to put the present, past climate changes, and projected future climate changes in context. The session invites contributions of new data of or methodological innovations for forcing reconstructions as well as model studies that highlight climate sensitivities or attributions of climate change to paleo-forcing records.
