Great Barrier Reefs Resist Back-to-Back Bleaching Events Through ‘Ecological Memory’

The Great Barrier Reef has been hit hard by climate change. As waters warm, the higher ocean temperatures force the coral to expel the algae that lives inside of it, providing it with both its nutrients and its brilliant colors. If the water does not cool fast enough and the algae does not return, the coral dies.

Scientists Discover 'Most Diverse Coral Site' on Great Barrier Reef

Australian scientists have found the "most diverse coral site" on the Great Barrier Reef, observing at least 195 different species of corals in space no longer than 500 meters, The Guardian reported.

The non-profit organization Great Barrier Reef Legacy and marine scientist Charlie Veron, a world expert on coral reefs, confirmed the diversity of the site, also known as the "Legacy Super Site" on the outer reef.

UN: Nations Must Triple Action to Avoid Disastrous Climate Change

The United Nations issued a wake-up call to world leaders on Tuesday for urgent climate action.

Despite national pledges to curb planet-warming emissions, the current pace of government action is "insufficient" to limit global warming to well below 2 C this century, much less the more ambitious 1.5 C target, the UN Environment Programme (UNEP) determined in its 2018 Emissions Gap Report.

The Seafloor Is Disappearing

By Marlene Cimons

Much of the deep sea has never been explored close-up by humans. Some submarines have plumbed its depths, but reaching the ocean bottom is a complicated and expensive journey, challenging because the seabed lies under more than three miles of water, which exerts huge amounts of pressure. "We know more about space than about the bottom of the oceans in our own planet, even though more than two-thirds of the surface of the Earth is covered by marine sediments," said Olivier Sulpis, a researcher and doctoral student at McGill University's department of earth and planetary sciences.

Island Paradise Palau to Be First Country to Ban Reef-Killing Sunscreen

The Western Pacific nation of Palau will become the first country in the world to impose a ban on sunscreens toxic to coral reefs, NPR reported Friday.

Hawaii passed a reef-harming sunscreen ban this summer, but the state law does not go into effect until 2021. Palau's law, passed this week, will go into effect in 2020. After that time, retailers will be fined $1,000 for selling sunscreens that contain 10 chemicals researchers believe are harmful to coral and other marine life, including oxybenzone and octinoxate, which are used in the majority of U.S. sunscreens.

NOAA Forecast: Great Barrier Reef Could Face Third Mass Bleaching Event in 4 Years

For any nature lover, one of the most sobering pieces of information from this month's Intergovernmental Panel on Climate Change (IPCC) report was that global warming of just two degrees Celsius above pre-industrial levels could kill off 99 percent of tropical coral reefs. And even if we act quickly and successfully limit warming to 1.5 degrees, 70 to 90 percent of these invaluable ecosystems will still be lost.

Now, an alarming forecast from the National Oceanic and Atmospheric Administration (NOAA) shows that process could begin as early as this Australian summer in one of the most iconic reefs of all: the Great Barrier Reef.

Animal Collective’s 'Tangerine Reef': Myth, Mystery and Subtle Environmentalism

By David Colgan

In a way, you could consider coral reefs the rainforests of the oceans—dense, mysterious and full of life.

Covering less than two percent of the ocean floor, they are home to a quarter of all marine species. But unlike rainforests, a longtime conservation focus, corals have received relatively little attention. The alien-looking seascapes have captivated explorers, divers and others privileged enough to visit, but remained largely out of sight for most people.

Australia to 'Absolutely' Exploit and Use Coal Despite IPCC Warning

Australia's coal-loving lawmakers dismissed the Intergovernmental Panel on Climate Change's (IPCC) warning to phase out the polluting fossil fuel by 2050.

In a recent interview with SkyNews, deputy prime minister Michael McCormack said Australia will "absolutely" continue to use and exploit its coal reserves regardless of what the IPCC report says.

'Completely Destroyed' Location for 'The Beach' Movie to Stay Closed to Tourists Indefinitely

Thailand's iconic Maya Bay, made popular by the Leonardo DiCaprio film The Beach, will be closed to tourists indefinitely, CNN Travel reported.

The beach had been closed temporarily since June 1 to restore the damage done by more than a million yearly visitors, but on Tuesday Thailand's Department of National Parks, Wildlife and Plant Conservation (DNP) announced the closure would continue "until natural resources return to normal."
