The world's oceans are becoming acidic at an "unprecedented rate" and may be souring more rapidly than at any time in the past 300 million years.

In their strongest statement yet on the issue, scientists say acidification could increase by 170% by 2100.

The report's co-author said acidification had already caused a 30% loss of species in some ocean ecosystems.

The researchers conclude that human emissions of CO2 are clearly to blame.

The study will be presented at global climate talks in Poland next week.

In a report setting out a plan for a "grand convergence" in health, the experts said world leaders needed to press for a concerted increase in research and development (R&D) investment to develop new medicines, vaccines and health technologies.

IRIN looks at some of the ways these innovations are transforming early warning and preparedness.
