The U.S. government’s oceans and waterways agency will provide $30 million to improve coastal resilience, officials said, aiming to reduce the impacts of worsening storms, flooding and rising seas in nearly half of U.S. states.

Grants through the program are designed to restore or expand coastal wetlands, dunes, reefs, mangroves and barrier islands that are key to coastal protection, said the National Oceanic and Atmospheric Administration (NOAA) in an announcement.

Coastlines worldwide are being damaged or threatened by more extreme and destructive weather, higher temperatures and rising seas that scientists attribute to the accumulation of greenhouse gases in the atmosphere.
