They lose their food source and colouring, and therefore look white, hence the term bleaching. The Great Barrier Reef, the only living structure visible from outer space, took hundreds of thousands of years to develop and is home to one of Earth’s most complex ecosystems. Great Barrier Reef: Half of natural wonder is ‘dead or dying’ and it is on the brink of extinction, scientists say. Roughly 30 percent of the corals on the Great Barrier Reef died after the 2016 bleaching, which was the worst of five separate bleaching events since 1998. The corals could recover, but they need more time— about 10 years for fast-growing corals. Observations from Queensland's ARC Centre of Excellence for Coral Reef Studies show detected mass depletion of every coral population in the Great Barrier Reef between 1995 and 2017, according to CNN.At this point, over half of it has died out as a whole, in both shallow and deep water. Hint: it mostly has to do with climate change. Ago Last week, a pretty distressing figure made waves — though probably not as many as it should have: 93 percent of the Great Barrier Reef (the world’s largest coral reef) is now in danger of dying. In the meantime, scientists who were conducting research in March before the coronavirus outbreak forced lockdowns said they had been saddened and frustrated by what they witnessed at sea. The reefs can’t live forever like this and die if conditions don’t improve. Just recently, the Queensland Labor Party approved Adani’s Carmichael megamine – set to be the largest in Australia.

Coral reefs provide a home for 25% of all marine life, are an incredible natural resource for breakthrough medicines, and half a billion people depend on them for food and work. Not only does do the warming waters affect the coral reef, but so does emitted carbon dioxide. Bleaching doesn’t kill corals by itself but weakens the corals and makes them vulnerable to disease. Christmas myths: The Krampus, Santa’s evil twin, Meet Islam’s Da Vinci: Al-Biruni, father of geodesy, anthropology, and master of pharmacy, Climate change. This higher acidity prevents corals from absorbing the calcium carbonate that they need to maintain their exoskeletons. The reef does this by absorbing most of the force of oncoming waves and protect shorelines. Recently, a slew of toxic chemicals were found in sea turtles, such as medications, pesticides, and metals. Unfortunately, that’s not even the end of what the reefs are up against. *Note: Reef = The Great Barrier Reef off the coast of north east Australia is one of the wonders of the natural world.

Yuletide is almost upon us! Half of the Great Barrier Reef's corals have died over the past 25 years, scientists said Wednesday, warning that climate change is irreversibly destroying the underwater ecosystem. It is another reason why we must stop climate change NOW. After a stretch of cooler weather in February, the overheating continued from late February through March, with scientists finding dead corals in shallow reef habitats, and bleaching in deeper reef slopes that were believed to be better protected. “We’re surprised by the pace of this acceleration in bleaching,” he said. The reefs are composed of a calcium carbonate exoskeleton that hosts colonies of hundreds of thousands of polyps. “It’s frustrating to still see reports of bleaching as a surprise,” she said. Mr Hughes says the Great Barrier Reef can no longer return to its state of even five years ago; in the coming decades, healthy coral is likely to be confined to ever smaller patches. For example, many animals and plants in coral reefs produce chemicals that could be important as medicine. Hundreds of millions of people get their protein primarily from reef fish like the coral trout, which is already being affected by the bleaching events on the Great Barrier Reef. Although ecosystem managers in Australia have worked hard to preserve the reefs, the past couple of decades have brought a new threat that can’t be solved by any one country alone: human-induced global warming. Fact: The Great Barrier Reef is greater in size than Tasmania and Victoria combined. But in many areas of the reef, for miles and miles, corals that were once colorful are now white, brittle and broken, or gray and covered with unsightly bacteria. Parts of Opal Reef, a popular dive tourism site and one of more than 2,900 individual reefs that make up the Great Barrier Reef system, suffered catastrophic mortality during the recent bleaching. Think about this — the reef has only experienced mass bleaching four times in total, 1998, 2002, 2016, 2017, and twice of those have been in the past two years.

The first recorded bleaching event along the Great Barrier Reef occurred in 1998 -- then the hottest year on record. Unfortunately, it’s dying. Studies have shown that this acidity could dissolve the skeletons of corals and make reefs fall apart. “We had a 14-year gap between 2002 and 2016, and now in five years we’ve had three severe events.”. The Reef protects a large chunk of the Australian coast (about 2,300 km), Australia would have to pay a lot to keep their shorelines and beaches from being washed away if the reef goes. What is most important to make sure that the reef survives is to make sure that it stays connected. Even more people visit the beaches that are protected by the reefs. Scientists say that one of our world's greatest natural treasures is now truly "terminal." Already, the ocean is 30% more acidic than in was in 1751 (pH change from 8.179 to 8.069). It keeps storms from causing damage to houses and people. The Great Barrier Reef, one of the seven natural wonders of the world, is dying.

She noted that scientists had warned 20 years ago that coral reefs would be at risk if humans did not address climate change, adding that many people who lived near them believed the science back then and are now demanding to know why more isn’t being done. This is good in a way because it takes away some of the CO2 that would contribute to the greenhouse effect, but it has a negative side on the ocean. The Great Barrier Reef is not entirely dead — it is large enough to support swaths of healthy coral. Combined with my love for nature (and biology background), I'm interested in diving deep into different topics- in the natural world even the most mundane is fascinating!
