California Wave Heights Growing Taller Due to Climate Change

Wave heights off California's coast have increased by about a foot since the 1970s due to warming oceans.
The frequency of waves over 13 feet tall has doubled from pre-1950s levels.
Scientists analyzed seismic records dating back to the 1930s to reconstruct historical wave heights.
Bigger waves are causing increased coastal erosion, flooding, and damage.
As oceans continue to warm, wave heights are expected to keep increasing, exacerbating coastal impacts.
