California Climate Change Assessment

On August 27, 2018, the California Natural Resources Agency released California’s Fourth Climate Change Assessment.  The goal of these assessments is to "provide the scientific foundation for understanding climate-related vulnerability at the local scale and informing resilience actions. The Climate Change Assessments directly inform State policies, plans, programs, and guidance to promote effective and integrated action to safeguard California from climate change."

The Key Findings summarize the impacts on people, infrastructure, and natural systems, and "provides critical information that will enable more ambitious efforts to support a climate-resilient California."

The Fourth Assessment included a Coast and Ocean Summary Report for the first time; this report synthesizes the latest research... about the challenges facing our coast and ocean because of climate change and what actions we can take to increase their resilience.

The Fourth Assessment study found that sea-level rise has become the dominant concern for coastal managers, and most also face funding and financing barriers.

According to the LA Times,

"At Surfers Point in Ventura County, officials turned an eroding parking lot and collapsing bike path into a cobble beach backed by vegetated dune. It has fended off erosion, widened the beach and become the most visited beach in Ventura County, the report said. During high wave conditions in the winter of 2015-16, no damage occurred at the project site: Wave run-up reached the bike path only where dunes were absent.

Other parts of the local shorelines were not so lucky: Ventura Pier was damaged in the storm and the Pierpoint neighborhood suffered inundation, the report said."
