A new NOAA outlook shows that many coral reefs across around the world will likely be exposed to higher-than-normal sea temperatures for an unprecedented1 third year in a row, leading to increased bleaching2 - and with no signs of stopping. While the bleaching event is global, it will hit the U.S. hard, especially in Hawaii, Guam, the Commonwealth3 of the Northern Mariana Islands, Florida Keys, U.S. Virgin4 Islands and Puerto Rico. The deeper reefs in the Flower Garden Banks National Marine5 Sanctuary6, 100 miles off the coast of Texas in the Gulf7 of Mexico, are also in the crosshairs.
 
NOAA Coral Reef Watch finds there is a 90 percent chance of widespread coral bleaching in the Pacific island nations of Palau and the Federated States of Micronesia during the probable La Nina. La Nina conditions can cause high ocean temperatures in the western Pacific. NOAA is currently predicting a 75 percent chance of La Nina development this year.
 
"It's time to shift this conversation to what can be done to conserve8 these amazing organisms in the face of this unprecedented global bleaching event," said Jennifer Koss, NOAA's Coral Reef Conservation Program director. "We have boots on the ground and fins9 in the water to reduce local stressors. Local conservation buys us time, but it isn't enough. Globally, we need to better understand what actions we all can take to combat the effects of climate change." 
 
NOAA is actively10 working with coastal11 resource managers and communities in coral reef areas to provide the best available science and tools to enhance reef resilience. The agency and its partners are also developing methods to assess the potential resilience of reefs so management officials can target and prioritize local conservation actions.
 
This third global coral bleaching event began in mid-2014 is ongoing12. Global warming, coupled with an intense El Nino, continues to make this the longest and most widespread coral bleaching event on record. Since its onset13, all U.S. coral reefs have seen above normal temperatures and more than 70 percent of them have been exposed to the prolonged high temperatures that can cause bleaching. Studies have shown that about 93 percent of Australia's Great Barrier Reef was bleached14 as of this April.
