• As the outlook for coral reefs across a warming planet grows grimmer, scientists in Israel have discovered a rare glimmer of hope: The corals of the northern Red Sea may survive, and even thrive, into the next century.
  • There is broad scientific consensus that the effects of climate change have devastated the world’s reefs, recently ravaging large swaths of the Great Barrier Reef in Australia, one of the natural wonders of the world.
  • The carbon dioxide that humans pump into the atmosphere spikes the temperature and acidity of seawater, which both poisons the marine invertebrates and hampers their growth at alarming rate.
  • But the corals at the northernmost tip of the Red Sea are exhibiting remarkable resistance to the rising water temperatures and acidification.
  • Corals worldwide are dying and suffering at a rapid pace, but we have not witnessed a single bleaching event in the Gulf of Aqaba.
  • As the outlook for coral reefs across our warming planet grows grimmer than ever, scientists have discovered a rare glimmer of hope: the corals of the northern Red Sea may survive, and even thrive, into the next century.
  • The coral reefs at the northernmost tip of the Red Sea are exhibiting remarkable resistance to the rising water temperatures and acidification facing the region, according recent research conducted by Interuniversity Institute for Marine Sciences.
  • Warmer water causes corals to eject the bjustifyly colored plants that serve as their primary food and oxygen source.
  • This causes reefs to “bleach,” or take on a bone-white pallor that often portends mass mortality.
  • While other hardy coral species can be found in the Indian and Pacific Oceans, “there’s nowhere else in the world that reefs are this far away from their bleaching thresholds,”
  • The Gulf of Aqaba has become a refuge for tough corals that are projected to outlast far worse future conditions.
  • The coral species’ thermal resistance carries over to their offspring, indicating that future generations will also remain immune to bleaching, with implications that could extend beyond this spot of the Red Sea.
  • The coral reefs at the northernmost tip of the Red Sea are exhibiting remarkable resistance to the rising water temperatures and acidification facing the region.
  • Only corals that could bear the heat managed to reach maturity and migrate north, where they resettled in conditions several degrees cooler than their thermal threshold.
