It's official: The carbon crisis is lethal for coral reefs
12-13-2007 · EurekAlert!Major new research indicates that coral reefs won't survive the rapid increases in global temperatures and atmospheric CO2 forecast by the IPCC. The livelihoods of 100 million people living along the coasts of tropical developing countries will be among the first casualties. Marine scientists argue for drastic action by world leaders on CO2 emissions. Immediate use of proven policy and management tools to address over-fishing, pollution and unsustainable coastal development is critical to saving coral reefs.

- Immediate action needed to save corals from climate change
12-13-2007 · EurekAlert!
The journal Science has published a paper today that is the most comprehensive review to date of the effects rising ocean temperatures are having on the world’s coral reefs. "The Carbon Crisis: Coral Reefs under Rapid Climate Change and Ocean Acidification," co-authored by 17 marine scientists from seven different countries, reveals that most coral reefs will not survive the drastic increases in global temperatures and atmospheric CO2 unless governments act immediately to combat current trends.

- Coral reefs unlikely to survive in acid oceans
12-14-2007 · EurekAlert!
Carbon emissions from human activities are not just heating up the globe, they are changing the ocean's chemistry. This could soon be fatal to coral reefs, which are havens for marine biodiversity and underpin the economies of many coastal communities. Scientists from the Carnegie Institution's Department of Global Ecology have calculated that if current carbon dioxide emission trends continue, by mid-century 98 percent of present-day reef habitats will be bathed in water too acidic for reef growth.

- Palau's coral reefs show differential habitat recovery following the 1998 bleaching event
05-15-2007 · EurekAlert!
Coral reef bleaching, believed to be one of the detrimental effects of climate change, may receive a welcomed "buffer" through effective local management, according to new research by a team of scientists recording the long-term recovery of coral reefs in Palau and elsewhere.

- Acid oceans warning
10-16-2007 · EurekAlert!
The world's oceans are becoming more acid, with potentially devastating consequences for corals and the marine organisms that build reefs and provide much of the Earth's breathable oxygen. The acidity is caused by the gradual buildup of carbon dioxide in the atmosphere, dissolving into the oceans. Scientists fear it could be lethal for animals with chalky skeletons which make up more than a third of the planet's marine life.

- Stormy days ahead for coral reefs
11-28-2006 · EurekAlert!
Scientists from the ARC Center of Excellence for Coral Reef Studies have produced the world's first engineering model to predict how much damage a reef is likely to suffer when confronted with an angry sea. In a paper in Nature, Dr. Joshua Madin and Dr. Sean Connolly use mathematical models to calculate the forces that coral is subjected to by waves or storm surge and the probability of the colonies being ripped from the seabed.

- Ancient coral reef tells the history of Kenya's soil erosion
04-10-2007 · EurekAlert!
Coral reefs, like tree rings, are natural archives of climate change. But oceanic corals also provide a faithful account of how people make use of land through history, says Stanford University scientist Robert B. Dunbar. In a recent study published in Geophysical Research Letters, Dunbar and his colleagues used coral samples from the Indian Ocean to create a 300-year record of soil erosion in Kenya.

- Ongoing collapse of coral reef shark populations
12-04-2006 · EurekAlert!
Investigators have revealed that coral reef shark populations are in the midst of rapid decline, and that "no-take zones" -- reefs where fishing is prohibited -- do protect sharks, but only when compliance with no-take regulations is high. The findings, reported by William Robbins and colleagues at James Cook University and its ARC Centre of Excellence for Coral Reef Studies, appear in the December 5th issue of Current Biology.

- Indo-Pacific coral reefs disappearing more rapidly than expected
08-07-2007 · EurekAlert!
Corals in the central and western Pacific ocean are dying faster than previously thought, University of North Carolina at Chapel Hill researchers have found. Nearly 600 square miles of reef have disappeared per year since the late 1960s, twice the rate of rainforest loss.

Large scale coral die-offs are now occurring more frequently than at any time in the last 11 000 years, according to a new study by Australian-based scientists.Investigations by Associate Professor John Pandolfi, of the ARC Centre of Excellence in Coral Reef Studies and the University of Queensland, of fossilized reefs in Papua New Guinea show how often the reefs were "wiped out" by disastrous events in past times.
