Western Atlantic corals face a critical test of resilience against rising heat

Western Atlantic corals are facing a critical test of resilience. Ever more frequent heat waves and resulting bleaching threaten extinction unless these ecosystems can adapt rapidly. The region's unique geography and long history of pollution have made corals especially vulnerable. Yet evidence shows thermal resilience is increasing through symbiont shuffling and natural selection. Assisted reproduction can accelerate this progress. These promising signs will come to nothing unless overexploitation and pollution are severely reduced.
