WP6
WP6 leader
Nathalie Sennechael has a backgroung in Physical Oceanography (doctor of the University Pierre et Marie Curie (UPMC) and is scientist at the MNHN -National Museum of Natural History- in Paris. Recently she has been increasingly involved in outreach activities. She is the ACCESS webmaster.
WP6 co-leader
Oystein Godoy has a background in meteorology and oceanography from University of Bergen. He has been working with remote sensing techniques at the Norwegian Meteorological Institute since 1994. In recent years he has been increasingly involved in data management activities e.g. for the EU project DAMOCLES and in operational data access during IPY.

DAY one, 5.9.2011
9:00 Opening, Introduction, Logistics
Part 1 Background: Climate Physics
9:30 Greenhouse gases and climate change (Peter Lemke)
(carbon inventory, radiation balance, temperature/moisture/heat transport/polar amplification, ice sheet etc mass balance, sea level, ocean acidification)
10:15 Aerosols and other anthropogenic impacts (Claire Granier)
(emissions of aerosols and other compounds, evaluation of anthropogenic emissions of aerosols, future scenarios, impact of biomass burning on the Arctic)
11:00 Break
Part 2 Climate Scenarios and Climate Models
11:15 Climate scenarios: An introduction (Kathrin Riemann-Campe)
(inputs, assumptions, uncertainties; CMIP3 vs. CMIP5; procedure of scenario generation, models of society, socio‐climatic feedbacks)
12:00 Climate model components and interactions (Annette Rinke)
(atmosphere, ocean, sea ice, land surfaces, ice sheets and shelves, marine biosphere, carbon cycle, equations, discretizations, coupling, resolution, parameterizations)
12:45 Lunch
14:00 Climate model results (Guy Brasseur)
(variables and their availability in public datasets; existing experiments and their purpose: pre‐industrial control, 20th century, comittment; scenarios and outcomes)
14:45 Biases and uncertainties (Michael Karcher & Frank Kauker)
(evaluation of climate models, focus on Arctic climate and especially sea ice)
15:30 Break
Part 3 What do we need from climate models and what can they deliver?
15:45 Discussion in outbreak groups (Leads from ACCESS WPs – Schwarz, Eide, Rehdanz, Parson)
(What data/information do I need? What can climate models provide? Alternative mechanisms of “scenario” generation)

Part 5 Natural variability vs. anthropogenic change
9:45 Observed variability from instrumental records and proxy data (Robert Spielhagen)
10:30 Break
11:00 Variability in long climate model runs (Øyvind Seland)
(How well do climate models capture long term natural variability?Causes of long term variability: internal modes, external – solar, volcanic aerosols; comparison of past long term variability and recent change)
