2008 Climate Action Team Report

Percent of historical (1961-1990) water year precipitation during 3 climate change periods (2005-2034, 2035,2064, 2070-2099) from 6 coupled models (CNRM CM3, GFDL CM2.1, MIROC3.2 (med), MPI ECHAM5, NCAR CCSM3, NCAR PCM1) and two climate change scenarios (SRESA2, SRESB1).
To meet the state's greenhouse gas reduction targets, Governor Arnold Schwarzenegger directed the Secretary of the California Environmental Protection Agency (CalEPA) to coordinate with several agencies (forming the Climate Action Team -- CAT). CAT releases a bi-annual report on the progress made toward meeting the statewide greenhouse gas targets.
The 2008 Climate Action Team Report work is in progress and a sneak peak at some preliminary results is offered here.

Success Stories

The California Applications Program (CAP) and the California Climate Change Center (CCCC) aim to develop and provide better climate information and forecasts for decision makers in California and the surrounding region. By working directly with users, CAP and CCCC are working to evaluate climate information needs and utility from the user perspective.

Objectives
  • Evaluate climate forecasts and projections for California
  • Improve understanding of mechanisms linking climate and its impacts
  • Develop local models and forecasts of water resources and fire risks
  • Disseminate climate information, including forecasts and projections, to California decision makers
Approach
  • Work directly with users to develop useful forecast applications
  • Downscale climate forecasts and simulations from global to regional to local scales
  • Determine forecast reliability using historical hindcasts
  • Provide a variety of forecasts in real time
Lessons Learned
  • Interest level of public and private sectors varies; Climatologists must be ready to strike when iron is hot
  • Simple, clear illustrations are needed
  • Relationships with end-users need to be cultivated
  • Communication enhances credibility
  • More focus is needed on non-winter seasons and broader regions
  • Collaborations with large institutional programs are key
  • Climate data needs to be updated and maintained

Californa Drought: An Update -- 2008
features
Changes in Aridity in the western United States
2002 distribution of areas with energy-limited evapotranspiration (black), water-limited evapotranspiration (white) and extremely water-limited or arid regions (yellow).
The West is relatively well-adapted to aridity. However during real droughts broad areas that are normally semi-arid or humid are subject to drier conditions. During droughts, the balance between waters that run off and those that evaporate back into the atmosphere are transformed temporarily. These changes color the entire region's water supplies and vegetation.

Governor Schwarzenegger Proclaims Drought
NOAA/ERSL PSD and CIRES-CDC
The percent of normal precipitation for the last two years (June 2006-May 2008) shows much of California at less than 60% of normal.
Following two straight years of below-average rainfall, very low snowmelt runoff and the largest court-ordered water transfer restrictions in state history, Governor Arnold Schwarzenegger today (June 4) proclaimed a statewide drought and issued an Executive Order, which takes immediate action to address a dire situation where numerous California communities are being forced to mandate water conservation or rationing. The lack of water has created other problems, such as extreme fire danger due to dry conditions, economic harm to urban and rural communities, loss of crops and the potential to degrade water quality in some regions.
