As sea levels rise along the Atlantic coast, saltwater is intruding inland, killing trees and turning coastal forests into marshes. Should scientists try to slow the process, or work with it?

Permanently protecting large, mature forests is a faster and cheaper way to stabilize Earth's climate than complex carbon capture and storage schemes, and more effective than planting new trees.
