Assessing Climate Variability and Change
Science on climate variability and change at PSW focuses on understanding historic and ongoing climate and climate mechanisms through proxies such as tree-rings pollen in lake sediments, and forest structural analysis, and on determining short-term climate and weather in relation to wildfire.
Climate has a profound influence in shaping the environment, natural resources, the economy, and other aspects of life throughout the world. How present climate changes will effect the environment is of central concern. In order to assess present climate changes it is necessary to have an idea of the historic patterns of climate. Research at PSW's Sierra Nevada Research Center is focused on determining historic climate patterns by looking at tree-ring records of living and ancient wood. Present climate can be compared to these historic patterns to show present climate changes. By looking at past climate variability and the resulting changes in vegetation patterns on the landscape, a picture of how ecosystems have been influenced by past climate emerges.
Fire and resource managers today must attempt to consider an array of resource, environmental, social, political, economic, and fire behavior parameters when making fire management decisions. Through the use of technology such as geographic information systems, expert systems, risk analysis, and modeling, we will look at ways to improve the availability and usefulness of complex data to decision makers.
Our research goal is to provide managers with flexible fuel management guidelines to protect forest health and enhance sustainability both under existing conditions and in the event of climate change. Relationships of climate, past fires, and forest dynamics are developed from tree rings, lake sediments, and written historical records. Fuel treatment effectiveness and fire effects on ecosystem components are studied through carefully designed experiments that compare a suite of treatment options.
