Dettinger 2018 <p>The Sierra Nevada region is critical to the environment and economy of California. Its places and peoples provide<br>essential natural resources including fresh water, clean power, working lands, and famous wilderness. The region<br>encompasses tremendous geographical, climatological, and ecological diversity that spans majestic mountains to<br>deep desert basins. The climate consists of cool, wet winters and warm, dry summers with large differences due to<br>latitude (e.g., the southern Sierra is snowier than northern Sierra) and topography (e.g., the Westside is wetter than<br>the Eastside). Variability is another notable feature of the climate with the region experiencing some of the largest<br>year-to-year climatic fluctuations in the United States. Herein we summarize our assessment of climate-change<br>vulnerabilities and adaptation actions in the region.</p> application/pdf en California Energy Commission/Natural Resoources Agency Sierra Nevada summary report.
