how to protect the great barrier reef from climate change

“Our overarching goal is to fill this critical knowledge gap to support resilience-based management for the island and its surrounding reef, giving us strategies to future-proof this important ecological and economic region,” Dr Townsend said. While coral doesn't die immediately, the bleachings have been intense enough to kill huge swaths of one of the world's most stunning natural wonders, including 29 percent of its shallow-water coral in 2016 alone. Farmers in Queensland use lots of fertiliser to grow sugar cane, a key crop. That might not seem like much, but it's enough to prompt the coral and algae to abandon their symbiotic relationship. “Reef islands are like modern day ‘arks’ as they afford protection and safety for an extraordinary diversity of wildlife,” she said. This one's so tough because scientists say it's caused by climate change. “It will give us a detailed baseline to monitor the impressive revegetation efforts on the island and assist in the interpretation of changes to surrounding coral reefs.”. There are 252 such sites in all, and the annual report tracks which ones are well protected long-term by current conservation measures. Climate change has caused an 89% decrease in new coral in the Great Barrier Reef, study finds. "If through climate change, for instance, the frequency of such ocean warming events or major cyclones increases over time, it means that there's less time between individual events for the corals to recover.". It's a coastal defence against tropical storms and strong ocean movements. Overfishing changes the natural balance of the reef, contributing to its struggle to recover. Made up of 3,000 individual reefs, the Great Barrier Reef stretches from the tip of Queensland, down to Hervey Bay, just north of Brisbane. Only the strongest and fastest possible actions to decrease global greenhouse gas emissions will reduce the risks and limit the impacts of climate change on the Reef. Researchers behind the study say local reef protection measures still play an important role in saving corals, even if those programs do not protect against climate change. “As the southernmost island in the Great Barrier Reef, it’s predicted to be one of the last to experience the increasing effects of global climate change, which makes it an excellent location to begin this process,” Dr Townsend said. We are already seeing the effects in many parts of the reef and, without help, the outlook is bleak,” Ms Marsden said. Reef 2050 Long-Term Sustainability Plan. Without zooxanthellae, the reef's tissue turns transparent and the coral starves. ABN 82 090 616 443. But tour operators say much of the reef still thrives, and their boats can help protect it. Reefs close to the shore are affected by river runoff. It’s possible. The condition of the Great Barrier Reef has worsened from "significant concern" to "critical" in a damning world heritage outlook report by a UNESCO advisory body. Led by the Great Barrier Reef Foundation, the Initiative is supported by funding from Lendlease, the Australian Government’s Reef Trust, the Queensland Government and the Fitzgerald Family Foundation. Scientists at the CSIRO, James Cook University and the Australian Institute of Marine Science, which runs a mammoth Sea Simulator near the reef, are looking for solutions. “This tailored, on-ground action program is set to expand existing environmental work on Lady Elliot Island,” Dr Townsend said. The surest way to save them is to curb global warming. Australia's Great Barrier Reef is large and diverse. No one would challenge the majesty of Australia's Great Barrier Reef.

The Smartest Stuff: Innovators are thinking up new ways to make you, and the things around you, smarter. A United Nations report has downgraded the outlook for the Great Barrier Reef to critical as climate change replaces invasive species as the biggest threat to … Polluted water runs off of the land, stressing coral. According to Townsville-based Australian Research Council’s Centre of Excellence for Coral Reef Studies, the renowned natural beauty near Australia has lost half of its corals over the past 25 years. Losing it would be a hit to Australia's economy, one of the strongest in the world. Dr Townsend said, despite its importance, scientific knowledge about Lady Elliot Island was limited. In 1981, the reef was designated a UNESCO World Heritage Site, a status that helps it draw 2 million visitors a year. The effects of climate change compound the impact other human activity has on the reef. Here we show that bleaching events of the past three decades have been mitigated by induced thermal tolerance of reef-building corals, and this protective mechanism is likely to be lost under near-future climate change scenarios. In short, losing the Great Barrier Reef would be a tragedy. © 2020 Great Barrier Reef Foundation. Southern reefs, in cooler waters farther from the equator, won't feel the brunt of bleaching. Coral doesn't die straight away when bleached. TERRY HUGHES, MARINE BIOLOGIST It's the number-one driver of the rapid decline of the Great Barrier Reef. The Great Barrier Reef will be irreversibly damaged by climate change in just 16 years, according to leading reef researcher Ove Hoegh-Guldberg. Further impacts can be minimised by limiting global temperature increase to the maximum extent possible and fast-tracking actions to build Reef resilience.
