Oceans as the planet’s dominant climate regulatorThe global ocean covers roughly 71% of Earth’s surface and acts as the primary regulator of climate. It absorbs and redistributes heat and carbon, moderating atmospheric temperature swings, determining weather patterns, and sustaining life-supporting biogeochemical cycles. Two fundamental roles stand out:Heat storage: The ocean has absorbed most of the surplus heat generated by greenhouse gas emissions—widely assessed as exceeding 90% of the planet’s accumulated excess warmth—thereby tempering atmospheric temperature rises while introducing long-lasting thermal inertia that commits the climate system to future shifts.Carbon sink: The ocean takes in a substantial share of CO2 released…
