The oceans are the world's greatest living chemical buffering solution.
Because the oceans contain such a colossal reservoir of dissolved inorganic carbon, they resist changes in pH. When CO₂ is added, the system shifts slightly but is anchored by the massive supply of carbonate from sediments and the weathering of continental rocks.
The 'methane bomb' is a common myth of the upper atmosphere. In the deep ocean, methanotrophic microbes act as a biological filter, consuming methane at the source. This is an elegant, built-in safety valve that has operated for millions of years.
Because water has a high specific heat and the ocean's volume is approximately 1.3 billion cubic kilometers, it acts as a global stabiliser.
Changes that might appear 'rapid' in a lab beaker take centuries or millennia to process in the deep blue.
