For example, the most rainfall on the Great Barrier Reef occurs in the rainy season, which starts in September and ends in March. El Niños generally mean less precipitation across northern Au… Coral bleachingoccurs when corals become heat-stressed enough to expel their primary source of food, the microalgae that live inside their cells. How coral bleaching works: the illustration from the U.S. National Ocean Service NOAA. “We surveyed 1,036 reefs from the air during the last two weeks in March, to measure the extent and severity of coral bleaching throughout the Barrier Reef region.”. So it’s a problem not just for Australia but for many countries including those whose livelihoods depend much more on the resources provided by coral reefs ... primarily in small, poor, rapidly developing countries.”. The latest follows February’s unusually hot summer–resulting in the highest ever sea surface temperatures recorded on the Reef since controls began in 1900.

Australia has 12 natural world heritage sites, four cultural world heritage sites and four mixed world heritage sites. This leaves the coral looking as white as if they had been soaking in bleach. “Warmer water temperatures can result in coral bleaching,” notes the, . He noted the IUCN had reviewed Australia’s protection and management of world heritage sites favourably, which he said was due to the “significant work” of federal, state and territory governments at those sites. U.S. lost half of its coral reefs in the Caribbean in one year due to a massive bleaching event, when warm waters around the Virgin Islands and Puerto Rico expanded south. This year was no different: the bleaching corresponded with a strong El Niño event. “Coral bleaching at regional scales is caused by spikes in sea temperatures during unusually hot summers,” say Terry Hughes and Morgan Pratchett. The Australian Marine Conservation Society’s Great Barrier Reef campaign manager, Dr Lissa Schindler, said: “The federal government’s refusal to act decisively on climate change is unforgivable when they know that global heating is so dangerous for our reef. increasingly serious global phenomenon caused by climate change, which is threatening the livelihood of those who live off the reef, such as those in French Polynesia, where this shot was taken in 2019.

The Great Barrier Reef, one of the seven wonders of the natural world, is at its greatest risk ever of disappearing into the annals of man-made disasters, due to mass coral bleaching caused by climate change. ", any accuse of being in climate change denial–. The renowned coral reef scientist, Terry Hughes, said it was logical the IUCN had moved the Great Barrier Reef into the critical category after three bleaching events in five years. For years, researchers have documented the increasing impact of climate change on the Great Barrier Reef, but very little is known about the reef's effect on the climate, particularly rainfall. RELATED: Climate change has killed half of the Great Barrier Reef's corals, study finds “The scale of bleaching is enormous during global bleaching events,” according to Professor Hughes, “the situation brings me to despair.” The first recorded mass bleaching along the Reef struck in 1998, at the time the hottest year on record. The results are “not a pretty picture”. Winter is known as the dry season and is characterised by warm temperatures and little rainfall while the summer season features higher temperatures and rainfall resulting in more humidity. seven wonders of the natural world, is at its greatest risk ever of disappearing into the annals of man-made disasters, due to mass coral bleaching caused by climate change.

It finds the conservation outlook for the Great Barrier Reef has worsened from “significant concern” to “critical” – the most urgent status under the IUCN system. The current bout of coral bleaching on the Reef, “the third in just five years”, is the “most severe and the most widespread” ever. The outlook has been published every three years since 2014. “As summers grow hotter and hotter, we no longer need an El Niño event to trigger mass bleaching at the scale of the Great Barrier Reef,” Professor Hughes says. “There is no doubt that if we are to learn from the recent devastating bushfires, as well as the findings in this report, we must commit to regenerating Australia and setting our nation on a pathway where both people and nature benefit,” she said. When a coral bleaches, it is not dead. In the aftermath of the 2019-20 bushfire disaster, the Gondwana rainforests – comprising 40 separate reserves between Newcastle and Brisbane – and the Greater Blue Mountains world heritage area have seen their outlook move to “significant concern” in 2020 from “good with some concerns” in 2017.

After climate change, the next two significant threats to these natural sites are invasive alien species and tourism impacts. The IUCN’s director general, Bruno Oberle, said countries owed it to future generations to protect the world’s “most precious places”. Last year the government’s Great Barrier Reef Marine Park Authority, charged with protecting the fragile ecosystem, downgraded its long-term outlook for the reef’s survival to "very poor." “About 70% of the world’s coral reefs now undergo these major bleaching events all at the same time.
