Rising sea levels in the Puget Sound region may prove costly to taxpayers. A city like Olympia could have to re-build its sewer system. Other cities may find waterfront roads washed out.

The culprit is global warming. Warmer water expands, bringing sea levels higher. And glacial ice that is above water now is expected to chunk off and fall into oceans, causing additional sea level rise.

With summer in full swing, area beaches see a lot of action. But the shores of the western coast of the United States may be hit with large-scale erosion in coming years, wiping out coastlines that provide protection from the surf, as well as pleasure.
