Wetlands and Marshes in a Changing Climate
Several years ago, scientists stopped studying whether human behavior was causing climate disruption and began looking into what change in climate meant for the planet over the long term. This clip follows marine scientist Nathaniel Weston, who has been meandering the tributaries of the Delaware River and investigating the implications of rising sea levels. Salt water intrusion into fresh water marshes will become a reality for the entire planet in the coming decades. This segment was put together by science journalist Miles O'Brien.
