Oceans serve as the world’s leading force in regulating climateThe global ocean spans about 71% of Earth’s surface and functions as the planet’s chief climate moderator, absorbing and redistributing heat and carbon to soften temperature fluctuations, shape weather systems, and maintain essential life-supporting biogeochemical processes. Two key functions are especially notable.Heat storage: The ocean has taken up the vast majority of excess heat from greenhouse gas emissions—commonly estimated at over 90% of the planet’s stored excess heat—slowing atmospheric warming but creating long-term thermal inertia that locks in future change.Carbon sink: The ocean absorbs a large fraction of human-emitted CO2—roughly a…
