Our climate is changing in unprecedented ways. Here in California, one effect of climate change—sea level rise—generates great concern for coastal cities. And the sea is already rising. Over the next century, sea level rise in the Los Angeles region is expected to match global projections with and increase of 0.1 – 0.6 m (5-24 inches) from 2000 to 2050 and 0.4 – 1.7 m (17-66 inches) from 2000 to 2100. Rising seas, combined with the threat of other coastal impacts such coastal erosion, high tides and severe storms are driving coastal communities to begin planning for these challenges and identifying strategies to adapt.
