Great Barrier Reef: the scale of bleaching has the most sober scientists worried, Guardian UK (04-16-2016)
I have dived hundreds of times, with different teams of scientists, along the reef. Yet the scale of this bleaching event has even the most sober and senior coral reef scientists worried. If the rhetoric from marine biologists is to be believed, then the Great Barrier Reef is now in the grip of a “bommie apocalypse”…

War on global warming only way to save world’s coral, study says; CBS News (03-15-2017)
Reducing pollution and curbing overfishing won’t prevent the severe bleaching that is killing coral at catastrophic rates, according to a study of Australia’s Great Barrier Reef. In the end, researchers say, the only way to save the world’s coral from heat-induced bleaching is with a war on global warming…

Coral reef experiment shows: acidification from carbon dioxide slows growth

Excerpts;

Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked, according to new research on Australia’s Great Barrier Reef led by Carnegie’s Ken Caldeira and the California Academy of Sciences’ Rebecca Albright.

Their work, published in Nature, represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. The acidity of the seawater was increased to reflect end-of-century projections if carbon dioxide from greenhouse gas emissions are not abated…

Nearly 500 tonne of plastic waste was removed from eight mangrove sites across Mumbai and suburban areas over the last two months. On an average, 70-80 tonne of plastic is removed every week, and 10-15 tonne every day.

Awareness about mangroves is now gripping Maharashtra. The participation by citizens too has risen from 720 to 14,400 within a couple of months time…

Scientists Pinpoint How Ocean Acidification Weakens Coral Skeletons


Photograph: © SAF — Coastal Care

Excerpts;

The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study identifies the details of how ocean acidification affects coral skeletons, allowing scientists to predict more precisely where corals will be more vulnerable.

Corals grow their skeletons upward toward sunlight and also thicken them to reinforce them.
The new research, led by scientists at Woods Hole Oceanographic Institution (WHOI), shows that ocean acidification particularly impedes the thickening process—decreasing the skeletons’ density and leaving them more vulnerable to breaking…

2018 International Year of the Reef, UNEP

Excerpts;

Over the last three decades, half of the planet’s coral has died under rising water temperatures and ocean acidification. To address this global crisis, global environmental leaders and countries have named this the International Year of the Reef.

Kicking off the International Year of the Reef, Prime Minister of Fiji Frank Bainimarama announced the nomination of large portions of Fiji’s Great Sea Reef as a Ramsar site in an effort to protect it from threats, such as climate change, chemical and waste water run-off from neighbouring urban settlement, and industry.

A Ramsar site is designated under international treaty as a wetland important for the conservation of global biological diversity and for sustaining human life. Under the convention, wetlands are broadly defined and include areas such as coral reefs.

“We are engaged in a battle for the future of these reefs. We approved the nomination of large parts of the Great Sea Reef as a Ramsar site to protect it for future generations,” Bainimarama said. “Today I appeal to every single person on earth to help us. We must replace the present culture of abuse with a culture of care.

Senior representatives from the United Nations and WWF took advantage of the occasion to announce a new collaboration driving an urgent global response to combat the decline of coral.

“This is a make or break year for the world’s coral reefs,” said Erik Solheim, Head of UN Environment. “We have a short window when we can act, and the United Nations, WWF, and countries like Fiji are calling on the world to take the steps that will fix the problem this year.”

“A healthy planet depends on healthy oceans which cannot exist without preserving coral reefs- a key pillar of WWF’s conservation work worldwide,” Marco Lambertini, Director-General of WWF International said. “While the world’s oceans are under pressure across the board, coral reefs stand out as needing a global response urgently. Holding a quarter of the ocean’s biodiversity and underpinning the lives and livelihoods of millions of people, the stakes could not be higher for corals – and humanity…”
