The role of the ocean in climate change

The oceans play a central role in global change processes.Major aspects of climate change are associated with the ocean’s heat transport, heat capacity, and the global water cycle. However, oceanic storage, transformation, transport and exchange of radiatively and chemically active gases and particles also exert an influence on climate through their impact on atmospheric radiation transfer. Past climate change has had demonstrable influences on the isotopic and chemical composition of seawater, which permits these signals to be investigated as potential recorders of change. Since exchanges of heat and substances between the ocean, land and the atmosphere operate on time scales ranging from seasons to millennia, they are amongst the most important factors for shaping future global climate change.
