9:00 AM: Introductions Marcia McNutt, Chair
NRC/Committee introductions, study background, and meeting objectives and ground rules

9:10 AM: Discussion of Committee's Task
Discussion continued from first meeting on what this study should address
9:10 AM: Gary Geernaert, Department of Energy
9:30 AM: Daniel Schrag, Harvard University
9:50 AM: Committee Discussion

10:30 AM: Break
10:40 AM: Session 1: Observations and Natural Analogues
What can be detected with satellites now that would be relevant to observing the experimentation or deployment of solar radiation management (SRM) techniques? (in particular for Earth's albedo and Stratospheric aerosols) What can be learned from natural analogues (e.g., volcanoes) about the effects of SRM techniques? And how well can we anticipate a volcanic eruption?
10:40 AM: Ralph Kahn, NASA -- Observational capabilities in radiation, clouds, albedo, and aerosols
11:00 AM: Charlie Mandeville, USGS -- Volcano eruption warnings
11:20 AM: Alan Robock, Rutgers University (remote presentation) -- Volcanic eruptions as analogs for stratospheric geoengineering
11:40 AM: Committee Discussion

12:30 PM Lunch

1:30 PM: Session 2: Geoengineering and the Public; Ethical and Equity Issues
How does society view geoengineering? What are the ethical and equity issues involved with geoengineering?
1:30 PM: Nick Pidgeon, Cardiff University (remote presentation) -- How does society view geoengineering?
1:50 PM: Stephen Gardiner, University of Washington (remote presentation) -- Ethical and equity issues with geoengineering
2:10 PM: Committee Discussion

2:45 PM: Break
3:00 PM: Session 3: Direct Air Capture; Carbon Sequestration and Storage
What do we know about the technology of direct air capture right now? What do we know about the potential for biological carbon storage? What do we know about how to store carbon for the long term? Where is the technology? What is the capacity (globally and in U.S.)? What is the role of climate policy?
3:00 PM: David Keith, Carbon Engineering -- Direct air capture
3:20 PM: Robert Jackson, Duke University -- Biological storage of carbon
3:40 PM: Jae Edmonds, PNNL-- Bioenergy, CCS, terrestrial sequestration, and climate policy
4:00 PM: Committee Discussion

5:00 PM: Open session ends

9:00 AM: Introductions -- Marcia McNutt, Chair

9:10 AM: Session 4: Policy, Governance, and Legal Issues
What existing legal structures relate to geoengineering? What types of governance structures have been proposed for geoengineering and/or what structures exist that are relevant?
9:10 AM: Susan Solomon, MIT (remote presentation) -- Volcanoes as natural analogues to solar radiation management (carry over from Tuesday discussion) and relevance of Montreal Protocol to geoengineering
9:30 AM: Scott Barrett, Columbia -- Governance of geoengineering
9:50 AM: David Keith, Harvard -- Governance and solar radiation management
10:10 AM: David Reidmiller, State Department -- Geoengineering in the context of international environmental policy
10:30 AM: David Winickoff, UC Berkeley (remote presentation) -- Governing Geoengineering Research: Are New Institutions Necessary?
10:50 AM: Committee Discussion
