A high-level international workshop convened by IPSO met at the University of Oxford earlier this year. It was the first inter-disciplinary international meeting of marine scientists of its kind and was designed to consider the cumulative impact of multiple stressors on the ocean, including warming, acidification, and overfishing.
The 3 day workshop, co-sponsored by the International Union for Conservation of Nature (IUCN), looked at the latest science across different disciplines.
The 27 participants from 18 organisations in 6 countries produced a grave assessment of current threats — and a stark conclusion about future risks to marine and human life if the current trajectory of damage continues: that the world's ocean is at high risk of entering a phase of extinction of marine species unprecedented in human history.
Delegates called for urgent and unequivocal action to halt further declines in ocean health. (click for press release)
The report summary (released 21 June 2011) outlines the main findings and recommendations. The full report will be released at a later date.

The report is also accompanied by four case studies, which look in more detail at some of the workshop's main findings.
