Researchers announced this month that a massive global coral bleaching event is jeopardizing the health of coral reefs around the world, and the crisis is still heating up. A triple threat of climate change, El Niño and a climate change-induced “warm blob” in the Pacific is causing the ocean to reach unusually high temperatures, stressing the coral animals that build reefs—the cradles of tropical marine life—and causing them to bleach, a stress response that often causes corals to starve, sicken and die. Researchers from the National Oceanic and Atmospheric Administration (NOAA) have gathered evidence suggesting that about 12% of reefs worldwide have already bleached in the last year, and predict that nearly half of those affected (over 12,000 square kilometers, or over 5% of reefs) could disappear forever.…
