PACLIM is a multidisciplinary workshop that broadly addresses the climatic phenomena occurring in the eastern Pacific Ocean and western North America. The purpose of the workshop is to understand climate effects in this region by bringing together specialists from diverse fields including physical, social, and biological sciences. Time scales from weather to the Quaternary are addressed in oral and poster presentations.

The theme of the 2007 PACLIM workshop addresses the impact of abrupt climate change on ecosystems. The remainder of the meeting is devoted to a wide range of climate-related topics.

The atmosphere of the workshop is intentionally informal, and room and board are provided for many of the participants. This year, the workshop was organized by representatives of the U.S. Geological Survey and U.S. Forest Service. The funding and other sources of support come from several agencies both public and private:

The CALFED Bay-Delta Science Program: Ron Ott and Steve Culberson
The Desert Research Institute: Chris Maples
The U.S. Geological Survey Geologic Discipline: Tom Armstrong
The U.S. Geological Survey Global Change Coordinating Committee: Virginia Burkett
The U.S. Naval Postgraduate School: Tom Murphree
