Finally tonight, new research and warnings about the risk of worsening flooding connected with climate change. A report released today by the research organization Climate Central finds the rise in sea level along many coastal communities is accelerating. By 2030, according to the report, nearly five million Americans living along coastal shores could be faced with storm surges up to four feet higher than their local tide lines. To help better understand the risk, Climate Central has created an interactive online mapping tool that shows the risk in cities up and down the coast.You can find a link to that tool on our website. For more on the study, we turn to its lead author, Ben Strauss. He is the director of the group's Sea Level Program. And, Ben, the report says that, globally, the sea level has risen about eight inches since 1880.Eight inches in 132 years, is that a lot? It may not sound like a lot, but it is.It's been enough to already double the chances for once a-century storms at most locations we 've studied around the United States. Now, the report concludes that both warming and sea level rise are accelerating, and that you expect to see much more of it in the coming years. Are there examples of particularly vulnerable places in the United States?
