Planning for Seven Generations: Observations and Projections of a Changing Climate - Caspar Ammann
(25 minutes)
Talk 7 of 14 on Day 1 of the Planning for Seven Generations Conference. According to Ammann, paleoclimatology has some similarities with the world view of native peoples. Climate is a continuum in which everything is interconnected. Scientists look for discontinuities in that continuum and are finding them in the extremes of precipitation, glacier collapse, and sea-level rise. Climate models are now partners to data in the study of climate change and the perspective is moving from global to local.

Planning for Seven Generations: UCAR President's Welcome
(5 minutes)
Talk 2 of 14 on Day 1 of the Planning for Seven Generations Conference. An important part of UCAR's mission, according to Anthes, is reaching out to the broader community to promote healthy, secure, prosperous, and sustainable life for all people on Earth. Anthes illustrates the challenges facing society with images of the melting ice cap and Hurricane Katrina and concludes with a brief description of UCAR and its work.

The Intersection of Science, Computational Science, and Information Technology: The Warren Washington Legacy
(18 minutes)
Talk 11 of 15 on Day 1 of the Warren Washington Symposium on Climate Modeling, Prediction, and Science Policy. After discussing the development of the Parallel Climate Model, Bader emphasizes today's need to integrate models and observations in order to improve predictive models. There needs to be an infrastructure for climate prediction that includes the rapid evaluation of new ideas, diagnostics, computing resources, and collaboratory technology.

Risk, Wealth, and Communications - Climate Policy Implications
(25 minutes)
Talk 1 of 7 on Day 2 of the Warren Washington Symposium on Climate Modeling, Prediction, and Science Policy. Baker cites Washington's long history of scientific accomplishments. He then outlines the keys to getting people and governments to invest in reducing carbon emissions. First, people need to understand the risk and act on it. China is a critical player here. Second, business must see that that there are profits and new wealth to be made from carbon sequestration. Lastly, more effective mass communication must get the science and issues to the public.

Variational Data Assimilation System (WRF-Var) Overview
(59 minutes)
Talk 15 of 19. This talk introduces a variational data assimilation system for the Weather Research and Forecasting model (WRF). Topics include the WRF-Var algorithm, background error modeling, FGAT (first guess at appropriate time), radar reflectivity, the gen_be utility to calculate local background error statistics, and global 3D-Var capabilities.

Implications of Going "Beyond" Science
(44 minutes, click title to view .mov with QuickTime)
Baron proposes a deliberate approach to climate change that he calls environmental rationalism. Based on a solid observing system, this approach would aim to both mitigate and adapt to climate change in order to protect life, property, and the planet while promoting economic vitality. However, neither the philosophical underpinnings nor the Earth management sciences needed are in place. Barron outlines five steps he believes are essential in order to meet the challenge.

Sustainability and Climate Change: Issues for Adaptation
(1 hour 37 minutes)
Need to think about climate change differently; There may be physical, ecological and societal 'tipping points'; Adaptation and mitigation are BOTH necessary; Adaptation research & options to cope are nascent; A rich interdisiplinary research agenda must be tackled now by physical scientists & social scientists, with questions defined by stakeholders

Space Weather: New Prospects for a Technology-Based Global Economy
(50 minutes)
Space weather traces its origins to the Sun's dynamic variability. It is driven by the combined actions of rotation, turbulent convection, and magnetic fields. Solar weather follows a quasi-11-year cycle and can be correlated with auroral activity. Bogdan lists three varieties of solar weather that are analogous to Earth's tornadoes, hurricanes, and wind. Solar weather can be forecast using the same kinds of tools that meteorologists use and is important to a growing client base. Our rapidly evolving high-tech global economy has become increasingly vulnerable to the effects of space weather on the health of airline workers, air transportation, satellite communications, warfare, fossil fuel extraction, power generation, human exploration, and commercial utilization of space.

Earth System Observations and Modeling: The Challenges for Tomorrow
(63 minutes, click title to view .mov with QuickTime)
Current challenges include predicting climate change, understanding the Earth as a complex interactive system, and unifying diverse models, while new emphases, according to Brasseur, will be geoengineering, short-term climate prediction, and methodologies coupling the natural Earth system to the human system. He anticipates a shift from fundamental research to climate services. An NSF Facilities User Workshop presentation.
