We would like to inform you that Ocean Acidification has been considered as one of World Meteorological Organization's Global Climate Indicators - a set of seven parameters that describe the changing climate without reducing climate change to only temperature. They comprise key information for the most relevant domains of climate change: temperature and energy, atmospheric composition, ocean and water as well as the cryosphere. These Global Climate Indicators have been identified by scientists and communication specialists in a discursive process led by GCOS during workshops and scientific panel meetings and have been finally endorsed by WMO. They form the basis of the annual WMO Statement of the State of the Global Climate, which is submitted to the Conference of Parties of the United Nations Framework Convention on Climate Change (UNFCCC).

These seven headline indicators are complemented by a set of subsidiary indicators that provide additional information and allow a more detailed picture of the changes in the respective domain.

The Global Climate Indicators are a concept that is meant be used to tell stories about climate change in a way that can be understood by non-experts. It is important to note, that the Global Climate Indicators are not limited to specific datasets or certain storylines. A multitude of narratives, told in different ways and forms and fitted to the respective auditorium, will catch more peoples interest and finally form a more comprehensive picture of climate change.
