The coral reefs of the world, on which the news focus section of this issue of Science concentrates, are important for all sorts of reasons. For many, exploration by diving provides a unique connection with a fascinating natural ecosystem. For scientists, including climate scientists, the health of reefs provides insight into the physical and biological welfare of the oceans as a whole.

Atmospheric carbon dioxide concentration is expected to exceed 500 parts per million and global temperatures to rise by at least 2

The South Pacific nations recently agreed to stop bottom trawling to protect corals and other marine life. Bottom trawling is a fishing method where boats tow heavy trawl nets along the sea

This report presents several case studies from selected natural and cultural World Heritage sites around the globe in order to illustrate the impacts of climate change that have already been observed and those that can be expected in the future. For each of the featured sites, ongoing and planned adaptation measures are reviewed, to give an indication of what may be possible by way of management responses to the different situations.

an endangered creature holds the key to arresting the decline of coral reefs. It is the batfish (Platax pinnatus). This timid fish has a surprising capacity of cleaning up dense weedy strands that

On the face of it, the ambitious Sethusamudram project to bridge the east coast with the west coast of the country seems a great idea. The prospect of not having to circumnavigate Sri Lanka and cutting short travel periods by 30 hours sounds as interesti

The visual media is into the business of producing images. Sometimes, just sometimes, they become iconic. For disasters there is a recognisable visual trope hungry people chasing, looting or scrabbling when a relief convoy happens by. Just as the hands

This special report does not seek to paint a comprehensive picture of the state of the oceans. It does not set out to recapitulate the many years of debate on ocean overfishing. WBGU concentrates instead on those key linkages between climate change and the oceans that are the topic of new scientific insights.These insights include new findings on warming, ocean currents, sea-level rise, carbon uptake and acidification, and on the impacts of these factors upon marine ecosystems.The report also discusses in detail the development of tropical cyclones, the issues surrounding carbon storage in the ocean or under the seabed, and the risks associated with methane hydrate deposits in the sea floor. Many of these issues are closely interlinked
