The ocean has been experiencing substantial changes in marine physics, chemistry and biology including ocean acidification, rising seawater temperature, ocean deoxygenation and sea level rise. These four, often interacting factors, are expected to increase over the coming decades depending on the concentration of greenhouse gases in the atmosphere. It is imperative that international decision-makers and stakeholders understand the enormous role the ocean plays in sustaining life on Earth, and the consequences of a high CO2 world for the ocean and society.
An international partnership * led by Plymouth Marine Laboratory has developed an overview of these four stressors, their impact and options for next steps:

Developed for the Commonwealth Marine Science Event 2018, this publication is an initiative by UK scientists and international partners, led by Plymouth Marine Laboratory, providing evidence-based science for policy making on the impacts of increasing concentrations of carbon dioxide and other greenhouse gases on the ocean and human systems.
This guide was also presented at the United Nations Framework Convention on Climate Change meeting (UNFCCC) in Bonn. PML and its international partners have been raising awareness on ocean matters at these UNFCCC meetings since 2009.

From the Arctic to the tropics, ocean acidification changes life in the sea. By absorbing carbon dioxide (CO2) from the atmosphere, the ocean slows down global climate change. But in seawater, the greenhouse gas causes a chemical reaction with far-reaching consequences: carbonic acid is formed, and the pH drops.
The German research network BIOACID examines the effects of acidification on the life and biogeochemical cycles in the ocean - and on all those who depend on it.

As a large sink, the ocean absorbs carbon dioxide from the atmosphere. But in sea water, the gas reacts to produce carbonic acid - a threat for organisms building their shells and skeletons from calcium carbonate. A film from GEOMAR | Helmholtz Centre for Ocean Research Kiel.
Ocean acidification - known as "the other CO2 problem" - is now also affecting the ecosystems of the Mediterranean. The scientific project MedSeA, funded by the European Community, has been studying the impacts of the phenomenon throughout the Mediterranean region for the last three and a half years. The video shows key information, scientific knowledge, and findings of the MedSeA Project, against the beautiful (and endangered) setting of the Mediterranean waters.
