Report: Humboldt Bay Sees Fastest Sea Level Rise on West Coast
A new North Coast Regional Report, part of California's Fifth Climate Change Assessment released in October, identifies Humboldt Bay as experiencing the fastest relative sea level rise of any NOAA station on the West Coast. The report warns that roughly one foot of rise since 1970 is accelerating, with projections of 1.3 to 1.5 feet by 2050 already causing king-tide flooding on Highway 101 between Arcata and Eureka. The 221-page document covers Humboldt, Mendocino, Del Norte, Lake, Siskiyou and Trinity counties, flagging risks to drainage systems, sewage plants, roads and low-lying communities including King Salmon.
