Secretary of the Interior Sally Jewell, Acting USGS Director Suzette Kimball, and San Francisco Mayor Ed Lee took part in a coastal climate change field trip led by USGS research geologist Patrick Barnard on December 18, 2014. The field trip visited two beaches along the outer coast of the San Francisco Peninsula that are within the most rapidly eroding stretch of California’s coast. Erosion is currently driven primarily by human influences on sand supply, but projected climate-change impacts, including sea-level rise and extreme storms, will increase the vulnerability of this urbanized coast to beach erosion, cliff failures, and coastal flooding, posing threats to private and public infrastructure, including a state highway and a $1.2-billion wastewater-treatment plant. The USGS has been active in understanding the various coastal processes that control this important section of coastline. For more information, contact Patrick Barnard,, 831-460-7556.
