Last time something like this was claimed, it was by stretching a report of limited recovery over small sections into "fully recovered"!

Data or it isn't true. Didn't see any data here. So just another propaganda piece by the pollyanna crowd "there's nothing wrong with the planet, and folks should just quit complaining!"

Oh, here it is. The reefs continue to be in decline with no relief in sight. That 30% is what they've declined to. Not a recovery. Over two thirds destroyed. Periodic bleaching events continue to utterly demolish local ecosystems.
