Apr 20, 2018 · The Great Barrier Reef corals were vulnerable because they've been subjected to warming oceans that are rapidly becoming more acidic. Those changes have been driven by human-caused greenhouse gas emissions, which are warming the world and causing Earth's climate to change faster than reefs can keep up.
Nov 7, 2019 · Australia’s Great Barrier Reef has declined by 50% since 1985, due to storm damage, coral bleaching and waves of crown-of-thorns starfish suffocating the coral. Warming ocean waters prevent corals laying down their calcium carbonate skeleton, which inhibits the growth essential for a healthy reef ecosystem.
Nov 15, 2021 · The Great Barrier Reef is in trouble. It has experienced five mass bleaching events since 1998, three of them in the last five years. Now, new research published in Current Biology Thursday finds that only two percent of the reef escaped some bleaching during that time. "This is one of the most confronting results of my career," study lead ...
Nov 30, 2021 · The Great Barrier Reef has been under threat from extinction for decades. Climate change has severely impacted the ocean's ecosystems, so seeing corals spawning gives scientists hope. The news is full of dire warnings about the future and current health of the Great Barrier Reef , but the World Heritage Site is not dead yet.
Jul 6, 2017 · Policies and projects that may damage the reef cannot go ahead. Deloitte Access Economics has valued the Great Barrier Reef at A$56 billion, with an economic contribution of A$6.4 billion per year. Yet this figure grossly underestimates the value of the reef, as it mainly focuses on tourism and the reef’s role as an Australian icon.
Nov 29, 2022 · K’gari is the world’s largest sand island and is key to understanding the development of the Great Barrier Reef, scientists say. New research suggests K'gari is older than the Greater Barrier Reef and has protected the reef from the northward drift of sand. K’gari is thought to be between 700,000 years and 1 million years old, while the ...
The bad news is that loads of dissolved inorganic nitrogen were lowered by only 17%, making it unlikely that the 50% reduction target will be reached by 2018. Nitrogen loads are up to nearly six times higher than natural background levels. Around 80,000 tonnes of pollutant nitrogen enters the Great Barrier Reef lagoon each year.

Scientists have found bleaching in the far northern parts of the Great Barrier Reef. This weekly round-up contains key nature and climate news from the past week. Top nature and climate stories: New warning over Great Barrier Reef bleaching ...
Dec 5, 2017 · The greatest threats to the reef are rising sea temperatures and ocean acidification. The Great Barrier Reef is better able to heal itself than we previously imagined, according to new research that identifies 112 individual reefs that can help drive the entire system towards recovery. The back-to-back bleaching events in 2016 and 2017 that ...
Jan 12, 2022 · 98% of the Great Barrier Reef has been affected by coral bleaching. Coral reefs are dying. This is where they are most affected. Between 2009 and 2018, coral cover progressively declined by 14%, primarily due to recurring large-scale coral bleaching events and inadequate time between events for coral to recover.
