These can vary widely with location and ecosystem, affecting both public and private sectors, often in unforeseen ways. As policymakers at national, regional, state and local levels grapple with how to mitigate and adapt to a changing and variable climate, industries must also prepare for and adapt to environmental and weather exigencies. New techniques in climate modeling will enable stakeholders to better predict impacts and prepare for them in a cost-effective way. The purpose of this briefing was to explore the knowledge generated by advanced regional climate modeling, cutting-edge modeling techniques, and the implications for corporate decision makers and regional policymakers. In Part 1 Oppenheimer introduces the key points of the briefing. 2009-09-18 11:00:00.0 Regional Climate Models: A Critical Adaptation Tool for Communities and Industry - Part 2: High Impact Climate and Weather Prediction Research in Support of Societal Needs Part 2 of 4.

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. An NSF Facilities User Workshop presentation. 2009-06-15 00:00:00.0 Earth System Observations and Modeling: The Challenges for Tomorrow 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. 2009-06-15 00:00:00.0 A Briefing on Climate Adaptation Policy Issues rtsp:// Panelists participating in this UCAR-sponsored briefing discuss how cities are planning to deal with climate change and how the federal government can help in that effort. New York City and Chicago are making progress in their mitigation and adaptation efforts. Other cities are struggling. Panelists advocate a national climate adaptation network so that planning efforts can be more integrated to avoid conflicts over water, land, and other resources. 2009-04-01 00:00:00.0 Some Uncomfortable Knowledge about Climate Change rtsp:// Pielke discusses the politicization of climate science, which brings with it the pathologies of politics. Political "culture wars" are being waged through science. A few scientists have begun to speak out on this situation, but more leadership is required. 2009-02-18 00:00:00.0 HIAPER Pole to Pole Observations (HIPPO) - Multimedia Gallery HIPPO is a three-year field project to make the most extensive airborne sampling of carbon dioxide and other greenhouse gases in the atmosphere to date, from the Arctic to the Antarctic. Study results will help scientists understand the behavior of these gases in the atmosphere and lead to improved predictions about climate change. 2009-01-29 00:00:00.0 START08 - Stratosphere-Troposphere Analyses of Regional Transport 2008 Experiment: Scientific Concept and Initial Results rtsp:// Using HIAPER, the NSF/NCAR Gulfstream V research aircraft, the START08 field campaign focused on transport in the upper troposphere and lower stratosphere. Pan discusses the experiment's concept and design process, highlights of the research flights, expected results, as well as various aspects of working on a research aircraft. 2009-01-21 00:00:00.0 The Need for Wind Profile Measurements from Space: Assimilation of Wind Data from the ADM/Aeolus Mission rtsp:// The Atmospheric Dynamics Mission (Aeolus) will provide line-of-sight wind profiles using a Doppler lidar measurement technique. Wind observations are particularly needed in tropical regions and in the midlatitudes. The latter area has implications for our understanding of the processes that govern Arctic warming and the retreat of Arctic sea ice. Additional objectives are aerosol information and cloud properties. 2008-12-19 00:00:00.0 Actions to Make Our Nation More Resilient to Severe Weather and Climate Change Panelists testify to the importance of investing in research related to severe weather and climate change. In order to adapt to these threats to economic and social stability, decision makers need local and regional scale information, but climate models are hampered by lack of research, observations, and computing at this scale. 2008-10-23 00:00:00.0 The Energy Challenge of Climate Change: More Urgent Than We Thought In this congressional briefing Wigley notes that the amount of carbon-free energy required to stabilize CO2 concentrations has been built into no-climate-policy scenarios. These assumed changes may be unrealistic in the face of rapid development in Asia. According to Edmonds, stabilizing CO2 concentrations at 550 ppm will require new science and technology to reduce the cost of such an effort. 2008-07-08 00:00:00.0 The Role of Moisture in the Madden-Julian Oscillation Randall's group has been using a superparameterized version of the Community Atmosphere Model (CAM) to study the Madden-Julian Oscillation. Comparing results to both observations and results from the conventional CAM, he presents an analysis of the processes that give rise to the MJO in the Super-CAM model. 2008-05-21 00:00:00.0 Weather Modification - Multimedia Gallery Commercial operators, governments, and academic researchers worldwide are engaging in cloud seeding and other weather modification projects to try to influence local conditions. NCAR scientists and their colleagues are investigating efforts to build up wintertime snowpack in the western United States and bring more rain to drought-stricken regions around the world. 2008-04-30 00:00:00.0 Planning for Seven Generations: The Perspective of the Next Generation - Bull Bennett and Casey Thornbrugh Talk 1 of 8 on Day 2 of the Planning for Seven Generations Conference. Bennet describes 21st century Indians as grounded in their own culture and able to integrate that with modern technology. Speaking from Arizona, Thornbrugh reviews the cultural background, mentoring, and education that have shaped him. In his life and teaching he tries to bring together his scientific training and the American Indian experience and culture. 2008-04-25 17:00:00.0 Planning for Seven Generations: The Perspective of the Next Generation - Bret Harper Talk 2 of 8 on Day 2 of the Planning for Seven Generations Conference. Harper, a former SOARS protégé, describes his research into ENSO's influence on the production of wind energy. He also discusses the state of the West Coast salmon fishery and his participation in a California tribal ecological knowledge program. The program's goal is restoration of tribal lands and of the tribe itself. 2008-04-25 16:00:00.0
