Global climate and the world ocean are inexorably linked. This is not merely because the ocean's ecosystems, like all others on earth, are affected by climate changes, but also because it is the oceans that drive planetary climate and weather. Changing climate changes the marine environment, but so too does a changing marine environment contribute to global climate change.
Water makes life possible - no other element is so universally required by living things. The bulk of our bodies is water, and all life on earth depends on it, either for drinking, nurturing eggs and young, or providing living space. Even ocean creatures rely on freshwater; all water is inexorably linked. This essential connection between freshwater and seawater underpins the great array of life in the sea.
In 1998, The Independent World Commission on the Future of the Oceans, chaired by Mario Soares of Portugal, issued the report, The Ocean: Our Future, its seminal analysis and recommendations for ocean policy in the 21st century.
High Seas: The Last Frontier for Oceans Management
Charlotte de Fontaubert, Ph.D.
The high seas are open ocean and deep-sea areas that lie beyond
national jurisdiction, covering more than a third of the Earth's
surface. Despite their extensive nature, these areas remain woefully
understudied and misunderstood. Until recent decades it was widely
assumed that below a depth of a few thousand meters, life was almost
impossible and mostly irrelevant.
Dropping pH in the Oceans Causing a Rising Tide of Alarm
Tundi Agardy, Ph.D.
One of the most unexpected consequences of global climate change may
well turn out to be one of the most severe in terms of impacts on life
on earth. As continued carbon emissions accelerate global warming, the
carbon dioxide contained in those emissions is able to silently yet
dramatically reduce the alkalinity of the oceans. And as the pH drops,
marine organisms that produce shells and carbonate skeletons grow weak
and die off.
