A recent study reveals how climate variability, particularly El Niño, influences the evolution of shorelines along the North American West Coast (NAWC).
Researchers analyzed waterline changes from 2000 to 2022, focusing on seasonal cycles and interannual fluctuations. They found that El Niño events correlate with significant shoreline erosion in the southern regions of the NAWC.
During El Niño winters, increased wave power and a southward shift in storm tracks lead to more pronounced erosion. Conversely, La Niña winters are associated with less erosion, especially in the southern areas.
The study highlights the complex interplay between climate modes and coastal dynamics, providing crucial insights for coastal management and adaptation strategies.
