California Coast Will See 6 Inches of Sea Level Rise by 2030, 3 Feet by 2100

By 2030, San Francisco will look just a little bit more like the underwater metropolis depicted in Burrito Justice's popular dystopian maps. A new report from the National Research Council shows that Californians can expect an average of six inches of sea level rise along the Pacific coast over the next twenty years.

The AP explains that the study

gives planners their best look yet at how melting ice sheets and warming oceans associated with climate change will raise sea levels along the country's Pacific coast ...

Although the six inches expected for California by 2030 seem minor, the report estimated that sea levels there will be three feet higher by 2100. About 72 percent of the state's coast is covered by sandy cliffs, and the rest include beaches, sand dunes, bays and estuaries.

All of which is ripe for erodin'! The rise is dramatic enough to present major headaches to city planners, coastal homeowners, and marine conservationists across the state.

As the report notes, "Rising seas increase the risk of coastal flooding, storm surge inundation, coastal erosion and shoreline retreat, and wetland loss." It will also increase coastal cities' vulnerabilities to storms. So, yeah. Bad news—climate change is eating away at one of the world's most beautiful coastlines.
