Session ID#: 13453

Session Description:
The Pliocene epoch (~2.6-5.3 million years ago) is arguably the best-resolved example of a climate state in long-term equilibrium with current or predicted near-future atmospheric CO2 concentrations. It was characterized by a warmer climate globally, reduced continental ice volume, and reduced ocean/atmosphere circulation intensity. Pleistocene paleoclimate studies have demonstrated the value of understanding climate variability on orbital timescales, whereby the unique spatial and temporal signatures of individual interglacials or glacial-interglacial cycles highlight sensitive regions or climate systems. Recent modeling work confirms that such variability (and regional non-synchronicity) should also be expected in the Pliocene.

As part of the PAGES PlioVAR working group, this session welcomes submissions which reconstruct and/or model mid and late Pliocene climates and environmental responses. Contributions investigating marine and terrestrial environmental change, ice-sheet behaviour, biotic responses and/or biogeochemical cycling are encouraged, so as to better understand climate forcings and feedbacks through both data analysis and data-model integration.
