A new online resource on Ocean Acidification has been launched that brings together new ocean acidification infographics, publications, background information, presentations and news for researchers, policymakers and the public.

Ocean acidification by numbers:

40%: The increase in atmospheric carbon dioxide (CO2) levels since the start of the industrial revolution.

26%: The increase in ocean acidity from preindustrial levels to today.

24 million: The number of tonnes of CO2 the ocean absorbs every day.

10 times: The current rate of acidification is over 10 times faster than any time in the last 55 million years.

The website ocean-acidification.net has been developed by the International Geosphere-Biosphere Programme (IGBP), the Intergovernmental Oceanographic Commission (IOC-UNESCO), the Scientific Committee on Oceanic Research (SCOR) and the Ocean Acidification International Coordination Center (OA-ICC) of the International Atomic Energy Agency (IAEA).
