The Impact of Climate Change on California's Ecosystem Services

Climate change impacts on the natural provision of biodiversity and four key ecosystem services in California (carbon sequestration, forage production, water for instream flows for salmon, and snow recreation), and the resulting change in market and non?market values of each service, are presented in this report.  Specifically, the study considers the effect of climate change on the social cost and the market value of carbon sequestration, the profits associated with the production of natural forage, and the consumer surplus of skiing and salmon fishing.

The report provides an overview of the climate change models and data, dynamic global vegetation modeling, species distribution modeling, water provision modeling, forage production modeling, and the valuation modeling for each service. Section 2.3 examines the potential economic impacts that may result due to the impact of climate change on ecosystem services.

Projections indicate the capacity of all four ecosystem services will decline under most scenarios of climate change, leading to a decline in the economic output for the state. The report also explains that the scientific understanding of the links between climate, ecosystems, and economic value is still poorly developed for California. A comprehensive research program focused on developing models and estimating the impacts of climate change on ecosystem services in California is suggested as an important tool for reversing current and future losses in the economic value of the state's natural ecosystems.
