DRAFT AGENDA
Monday, May 5, 2008
8.15 a.m. Continental Breakfast
9.00 Welcome Statement - Dick Norris, Committee Chair
9.30 PLENARY ADDRESS: Simulating Earth's Climate: Past, Present & Future - Jeff Kiehl
10.00-10.30 Break
10.30 PLENARY ADDRESS: Rapid Environmental Change and Feedbacks: Lessons from Deep Time - Jim Zachos
11.00-12.30 BREAKOUT-I: Events and Transitions, Tipping Points, and Thresholds
Question 1: What evidence can we use to identify thresholds and tipping points in the geologic record?
Question 2: What are the best parts of the record to target—and what are the proxies to use—to describe and categorize thresholds and tipping points in the record? What are the non-linear processes that determine critical ‘tipping points,’ and are these processes well-represented in climate models and in biota-climate models?
12.30-1.30 Lunch
1.30 PLENARY ADDRESS: Carbon cycling and climate sensitivity across the Paleocene-Eocene boundary - Richard Zeebe
2.00-3.30 BREAKOUT-II: Coupling and Decoupling Climate Sensitivity
Question 3: What physical and biogeochemical feedback processes are most important in determining the climate sensitivity to a large dynamic range of forcing?
Question 4: What can deep time records and models tell us about climate sensitivity?
3.30-4.00 Break
4.00-5.30 BREAKOUT REPORTS – Questions 1-4
5.30-7.00 Reception at the Beckman Center
Tuesday, May 6, 2008
8.15 a.m. Continental Breakfast
9.00 NSF hopes and expectations - Rich Lane, National Science Foundation
9.30 PLENARY ADDRESS: Dinosaur forecast - cloudy! A convective-cloud mechanism for past equable climates and its role in future greenhouse scenarios - Eli Tziperman
10.00-10.30 Break
10.30-12.00 BREAKOUT-III: Alternative Worlds
Question 5: What are the most poorly understood dynamics of past ‘alternative worlds,’ and which ‘alternative world’ intervals offer the greatest potential for understanding future climates?
Question 6: What kinds of proxy evidence do we need to advance understanding of the dominant processes that operate in these ‘alternative world’ intervals?
12.00-1.00 Lunch
1.00-2.30 BREAKOUT-IV: Implementation and Infrastructure
Question 7: Describe the infrastructure that will be required to answer these questions?
Question 8: How do we improve interactions between deep time data/model research?
Question 9: What are the best options for additional paleoenvironmental and geochronological proxies (e.g., biomarkers and isotopes of biomarkers).
2.30-3.00 Break
3.00-4.30 BREAKOUT REPORTS – Questions 5-9
4.30 Wrap-up and Thanks - Dick Norris, Committee Chair
5.00 Adjourn
Wednesday, May 7, 2008
