Coral Reefs and Climate Change: the guide for education and awareness book #

Coral Reefs and Climate Change: the guide for education and awareness

June 23, 2010

The CoralWatch team at UQ has just produced a new book “Coral Reefs and Climate Change: the guide for education and awareness”.

This book focuses on coral reefs, the astonishing abundance of life within them and the impacts of climate change on this beautiful environment. There is hope for reefs but we must act now. Coral reefs are being lost more than five times faster than rainforest and it is up to us to prevent their continued degradation.

The book explains the effects of climate change by using coral reefs as an example. Its aim is to inform, educate and enable people to begin to question the future that we are creating right now. It combines some of the latest scientific research with informative imagery to cover topics such as oceanography, coral reef biology, the issues of climate change and suggestions for ways forward. The book is not aimed at scientists but at educators, students, reef enthusiasts, professionals and interested people.

28 min video - Climate Change: Coral Reefs on the Edge

December 28, 2009

In clear and direct language, one of the world's leading coral biologists, Professor Ove Hoegh-Guldberg, presents his scientific findings that show how C02 emissions are pushing the world's coral reefs to the brink of extinction.

Produced by Plankton Productions, Specialty Studios and Education Services Australia, this 28 min video explains the issues and features breathtaking images of coral reefs from David Hannans collection.

In this video, Prof. Hoegh-Guldberg describes how increased CO2 emissions have led to warming of the seas and increased ocean acidification, which may both cause the disappearance of coral reef in the next few decades. He warns that current efforts to curb C02 emissions are falling well short of what's needed to protect coral reefs.

Professor Ove Hoegh-Guldberg, Ph. D. is currently Director of the Global Change Institute at the University of Queensland, Australia.

Sea Sick - The Global Ocean in Crisis book #

Book review for "Sea Sick" by Alanna Mitchell

March 3, 2009
written by Toni Houston

Sea Sick is the first book to examine the current state of the world’s ocean system, and the dire impact of humankind.

Human activity is altering the ocean in every way, from temperature to salinity, from acidity to circulation. Each of these changes not only drastically affects the marine world, but more alarming has dire consequences for all life on earth.

This is where the planet's most serious ecological crisis is unfolding, and unfolding fast - in the Oceans.

Author Alanna Mitchell joins the crews of leading scientists in nine of the global ocean’s hotspots to see firsthand what is really happening around the world. Whether it’s the impact of coral reef bleaching, the puzzle of the oxygen-less dead zones such as the one in the Gulf of Mexico, or the shocking implications of the changing pH balance of the sea, Mitchell explains the science behind the story to create an engaging, accessible yet authoritative account.

Like countless scientists around the world, her research produces an alarming prognosis for the health of our planet, and reveals that we are at a critical 'tipping point'.

Corals in the Keppel Island Region Form New Heat-Beating Partnerships

March 20, 2008

In the first observation of its kind, a coral community in the southern inshore region of the Great Barrier Reef is showing signs of adjusting to higher sea surface temperature by quickly changing its main algal partners to types that can better cope with the heat.

An AIMS field study near Miall Island, part of the Keppel group of 15 islands on the southern Great Barrier Reef off the Queensland coast near Rockhampton, has revealed a remarkable feat of acclimatisation; the only time such an event has been observed in natural conditions on a coral reef.

The work, which appears today in the prestigious UK scientific journal the Proceedings of the Royal Society, has shown that a phenomenon known as "symbiont shuffling" took place after a bleaching event in 2006 in the Acropora millepora coral population studied.

Alarm bells as Evidence of Slowed Coral Growth on the Great Barrier Reef Emerges

March 5, 2008

Worrying signs that warmer seawater combined with a possible change in the ocean's acid balance may be curtailing the growth of an important reef-building coral species have been documented by a research team from AIMS in Townsville.

The paper, published in the journal Global Change Biology*, points to a 21 per cent decline in the rate at which Porites corals in two regions of the northern Great Barrier Reef (GBR) have added to their calcium carbonate skeletons over the past 16 years.

The AIMS research team analysed a total of 38 Porites colonies from the two regions. Porites are a common massive coral with a striking spherical appearance. They are long-lived and distributed widely around the Indian and Pacific oceans.

Campaign to Stop Shark Finning on the Great Barrier Reef

February, 2008

An alarming new proposal by the Queensland Government will establish a dedicated shark fishery in the Great Barrier Reef World Heritage Area which will service the international trade in shark fin.

The Australian Marine Conservation Society (and anyone who cares for our oceans) is astonished by this proposal, in which Queensland's fisheries department (DPI&F) plans to legitimise one of the most unsustainable forms of fishing on the planet - shark fin fishing. With over 90% of the world's sharks and other big fish gone from our oceans, this project is unsustainable, unethical and will be flatly rejected by the Australian public.

Not only is the Queensland Government proposing to hand out specific fishing licenses for shark fin fishing, which will entrench the practice for years, they are planning to legitimise shark fishing in the Great Barrier Reef World Heritage Area and in the Marine Parks of Moreton Bay and the Great Sandy Straits with this new license proposal.

Report Warns about Carbon Dioxide Threats to Marine Life

July 5, 2006

BOULDER - Worldwide emissions of carbon dioxide from fossil fuel burning are dramatically altering ocean chemistry and threatening marine organisms, including corals, that secrete skeletal structures and support oceanic biodiversity. A landmark report released today summarizes the known effects of increased atmospheric carbon dioxide on these organisms, known as marine calcifiers, and recommends future research for determining the extent of the impacts.

"It is clear that seawater chemistry will change in coming decades and centuries in ways that will dramatically alter marine life," says Joan Kleypas, the report's lead author and a scientist at the National Center for Atmospheric Research (NCAR) in Boulder. "But we are only beginning to understand the complex interactions between large-scale chemistry changes and marine ecology. It is vital to develop research strategies to better understand the long-term vulnerabilities of sensitive marine organisms to these changes."
