Tropical coral reefs are at a critical tipping point, and we’ve pushed them there, scientists say. Climate change may now cause previously rare, devastating coral bleaching events to occur in tropical coral reefs around the globe on a ‘near-annual’ basis, reported The Guardian. In February 2020, record-high sea temperatures at Australia’s Great Barrier Reef caused […]
By Michael Mann After years studying the climate, my work has brought me to Sydney where I’m studying the linkages between climate change and extreme weather events. Prior to beginning my sabbatical stay in Sydney, I took the opportunity this holiday season to vacation in Australia with my family. We went to see the Great […]
A team of British and Australian scientists have discovered an innovative way to help coral reefs recover from the climate crisis and other human-caused damage: loudspeakers. A healthy fish population can help fight the degradation of coral reefs, the study’s authors explained in Nature Communications Friday, but damaged reefs don’t attract as many fish because […]
By Marlene Cimons Scientist Tim Gordon studies how rising temperatures are damaging corals in Australia’s Great Barrier Reef, where intense cyclones and warm waters have caused extensive damage in recent years. What he sees brings him to tears. “They used to be some of the most colorful, vibrant, bustling, noisy ecosystems in the world, but […]
The government agency that manages Australia’s Great Barrier Reef on Friday downgraded its outlook for the condition of the coral system from “poor” to “very poor.” The Great Barrier Reef Marine Park Authority’s (GBRMPA) report blamed climate change for coral bleaching, which occurs as a result of rising sea temperatures. “Significant global action to address […]
Could an undersea volcanic eruption help the Great Barrier Reef recover from coral bleaching? A Manhattan-size raft of pumice stones ― believed to be the result of an undersea eruption near Tonga ― is floating on the Pacific Ocean towards Australia, CNN reported Monday. The pumice carries with it marine organisms like crabs and corals […]
Marine heat waves are increasing in frequency, duration and intensity, which spell trouble for corals, according to new research from scientists working at the Great Barrier Reef. The increased frequency in heat waves is a direct byproduct of the climate crisis the scientists say, as the BBC reported. The researchers knew that oceanic heat waves […]
The federal agency that manages the Great Barrier Reef issued an unprecedented statement that broke ranks with Australia’s conservative government and called for urgent action to reduce greenhouse gas emissions, according to the Guardian. The position statement issued by the Great Barrier Reef Marine Park Authority is unequivocal in its stance that the climate crisis […]
A changing climate is altering oceans in major ways and coral reefs around the planet may not be able to adapt to survive. Ocean acidification (OA) occurs when carbon dioxide from the atmosphere is absorbed by seawater, resulting in a chemical reaction that reduces pH and calcium carbonate levels vital for the growth and repair […]
