Sea Change: How High Will the Sea Rise

Sea Change follows the work of scientists who seek to improve predictions of sea-level rise in the future by learning how high the sea has risen in the past.

The Earth is getting hotter. As a result, sea levels are rising. With about 40 percent of the world's population and 55 percent of Americans living near a coast, the height of sea levels in the future is a big concern for people around the world. Higher water will alter the lives of many people living in these locations in coming decades. Sea Change explains what scientists know now and how they’re learning more. Visit interactive features about the Earth's changing climate or view a series of videos explaining how the researchers are discovering how high sea-levels reached during the Pliocene, about 3 million years ago, a time considered analogous to the near future. The project is the first systematic effort to search around the world for Pliocene-age beaches and come up with a more accurate estimate of Pliocene sea levels.
