Micronesian Mangrove Forests Show Some Resilience to Sea-Level Rise

In a recent report supported by the Pacific Islands CASC, researchers modeled how mangrove forests in the Federated States of Micronesia may respond to sea-level rise in coming decades. They projected that island mangroves will likely be resilient to low and moderate sea-level rise rates, but that extreme changes in water levels could outpace natural climate adaptation mechanisms. ...
