In the marsh lands of New Jersey’s Pine Barrens, you may stumble across a spooky sight: hundreds of dead Atlantic white cedars poking out of the water. Some people call these places “ghost forests”.  Able: “Locally, we refer to these as cedar cemeteries.” Ken Able directs the Rutgers University Marine Field Station. He says cedar trees need fresh water to live. As sea levels rise, salt water slowly creeps inland, killing trees and converting forest to marsh. Seas have been rising for a long time, and Able says some drowned trees have been around for centuries. But as climate change speeds up the process, trees are dying in larger numbers than ever before.
