Annual Report 2010—2011 III IV Australian Climate Change Science Program Foreword The Australian Climate Change In 2010-11, more than 100 climate scientists throughout Australia worked on more than Science Program (ACCSP) has a 30 projects across seven program areas that major role in informing Australia’s addressed national climate priorities. As well key decision makers and as carrying out climate change research, the scientists presented their findings improving our understanding at workshops, conferences and many of the causes, nature, other local and international events. They timing and consequences published their findings in 147 peer-reviewed papers in Australian and international of climate change. publications and 45 other publications for workshops, conferences, and other events. The science undertaken by the ACCSP in the reporting year addressed the following themes: greenhouse gases, atmosphere, oceans and coasts, water, an Australian climate modelling system, extremes and communication. Outcomes of the science provided new, or supported existing, scientific evidence for human- induced climate change and improved our understanding of climate change. As well as undertaking world-class research, communicating the outcomes of climate science is an important objective of the ACCSP. This annual report includes a list of peer-reviewed publications from research conducted under the auspices of the ACCSP, along with media releases, Australia’s climate change websites and climate change video clips answering some commonly asked questions about climate change. We would like to acknowledge the key people and organisations that have made it possible for the ACCSP to deliver world-class climate change science for Australia. We thank our scientists and other staff who are passionate about what they do and who are committed to improving our understanding of climate change and the challenges ahead. We would also like to acknowledge the Department of Climate Change and Energy Efficiency, which has supported CSIRO and Mr Paul Holper Dr Robert Colman the Bureau of Meteorology as the providers of the climate science undertaken by the Manager, Climate Variability and Change Program, ACCSP. This collaboration has been critical in CSIRO, Australian Climate Centre for Australian Weather and helping Australia to understand the impacts Change Science Program Climate Research, of climate change, develop ways to adapt Bureau of Meteorology and to manage its carbon emissions. Annual Report 2010—2011 1 Vision About Working together To be a world-class provider of science- The Australian Climate Change Since 1989, the Australian Government based knowledge on climate change Science Program (ACCSP) is the has supported climate change research in the Southern Hemisphere. key Australian Government climate undertaken by CSIRO, the Bureau of change science program. Meteorology and other agencies. The world-class science carried out It does this mainly through the ACCSP, by the ACCSP informs Australia’s key which is a partnership between the decision makers and improves our Department of Climate Change and understanding of the causes, nature, timing Energy Efficiency (DCCEE), CSIRO and and consequences of climate change. the Bureau of Meteorology (BoM). The ACCSP plays a significant role in With co-investment by CSIRO and BoM, contributing to, and informing, public the ACCSP represented investment of policy and debate in climate change. approximately $15m in 2010-11 in research directed to meet the shared goals and Climate change science priorities of CSIRO, BoM, and DCCEE. These goals and priorities were advanced by the Science undertaken by the ACCSP focuses joint research program between CSIRO on the Southern Hemisphere because and BoM through the Centre for Australian most other climate change science is Weather and Climate Research (CAWCR). generated in the Northern Hemisphere and does not provide all the information needed for Australian decision making. In 2010-11, the ACCSP comprised 33 projects across the following program areas: 1. Global and regional carbon budgets 2. Land and air (observations and processes) 3. Oceans and coasts 4. Modes of climate variability and change 5. Earth system modelling and data integration 6. Predicting Australia’s future climate and its extremes 7. Communication and co-ordination. See Appendix 1 for a list of the ACCSP projects carried out in 2010-11. 2 Australian Climate Change Science Program National climate International science priorities collaboration Projects conducted under the ACCSP The Framework comprises The ACCSP ensures that Australian in 2010-11 aligned with the Australian four main elements: climate change science continues to Government’s priorities for climate system be recognised internationally by: • challenges (what we need to understand science.
