The coral bleaching faced by many coral reefs across the world including the Great Barrier Reef of Australia is now coming to an end but it’s too early to celebrate the joy. The coral bleaching which lasted almost for 3 years is supposed to be ending soon and the news comes from scientists who announced the same on June 19.
Coral bleaching event has caused damage to almost three-quarter of corals globally which were destroyed completely and killed due to rising water temperatures. The bleaching is characterized by symbiotic algae which turn from green color to white or pale color. This coloring destroys the corals and results in death.
According to National Oceanic and Atmospheric Administration (NOAA), the bleaching event which had taken place in 2014 was the worst one compared to the bleaching events reported between 1998 and 2010. The increased water temperatures caused by global warming in May 2014 across Pacific and Atlantic coast which has been lasted for 3 continuous years have caused huge damage and mass death of corals.
According to NOAA this coral bleaching event is slowly easing and the positive effects were shown by data gathered from satellites and modeling. According to Mark Eakin, a watch coordinator at NOAA said that 95 percent of all marine species has been destroyed due to this bleaching event.
However, the reports claim that there won’t be much damage to Indian ocean but the Pacific and Caribbean oceans are still facing the threat due to coral bleaching but its impact has been lowered down significantly. The places which were the greatest hit due to coral bleaching include the Great Barrier Reef, northwest Hawaii, Guam and some regions of Caribbean.
The regions affected by coral regions are improving but it’s too early to celebrate the good news and global warming and El Niño were the contributors to the bleaching event. But the researchers are worried as the improving situations may not boost the survival of corals even in favorable conditions. Coral reefs are the primary source of fishery and tourism and the first indicator of global warming.
