General Meeting Information

The Climate Impacts Group's (CIG's) climate and water fall forecast meeting provided an opportunity to hear how forecasted climate conditions for winter 2008-2009 may affect regional climate and streamflow conditions in the Columbia and Snake River Basins in summer 2009. The meeting also provided a forum for sharing the latest research on climate impacts and climate forecasting in the Pacific Northwest (PNW). The meeting was jointly sponsored by the CIG and Idaho Department of Water Resources.

Washington Climate Impacts Assessment - February 12, 2009
(website coming)

The Climate Impacts Group, in partnership with Washington State University and Pacific Northwest National Laboratory, is conducting a first-ever climate impacts assessment for the state of Washington. The assessment evaluates the impacts of climate change on the following sectors: agriculture, coasts, energy, forests, human health, hydrology and water resources, infrastructure (specifically related to stormwater management), and salmon. The work, funded by the Washington State Legislature in 2007, will be completed by December 2008.

The CIG will convene a one day conference on February 12, 2009, in Seattle to share the results of the Washington Climate Impacts Assessment. A conference website, agenda, and registration information will be available soon. In the mean time, please contact the CIG with any questions.
