85th AMS Annual Meeting

Tuesday, 11 January 2005: 2:00 PM
The CLIVAR/PAGES/IPCC workshop on a multi-millennia perspective on drought and implications for the future
Kevin E. Trenberth, NCAR, Boulder, CO
What is the full range of past drought variability, as revealed by paleoclimate data? What role might droughts associated with abrupt climate change play? Are droughts likely to become more frequent, longer, or more extensive as we move into the future with global warming? All of these considerations were motivation for organizing a meeting, "A Multi millennia Perspective on Drought and Implications for the Future." It was organized by the international CLIVAR PAGES [CLIVAR is the World Climate Research Programís project on Climate Variability and Predictability, and PAGES is the International Geosphere Biosphere Programmeís project on Past Global Changes] joint working group, which brings together the climate dynamics and paleo communities. Drought is among the topics of the Intergovernmental Panel on Climate Change (IPCC) for the forthcoming 2007 fourth assessment report (AR4), and co-sponsorship of the meeting by the IPCC enabled attendance by scientists from developing countries in Africa and elsewhere. The purpose of the meeting, which was attended by about 70 people, was to bring a focus on new ideas, observations, analyses, and theories about drought to improve understanding, analysis approaches, and predictive capabilities. The results of the wide-ranging discussions and recommendations will be presented.
