Surface ocean warming appears to be speeding up global currents, reconstructed here from satellite and ship readings. Climate and ecosystems everywhere on Earth, even those far from the ocean, are affected by the ocean circulation. Global ocean physical and chemical trends are reviewed and updated using seven key ocean climate change indicators: (i) Sea Surface Temperature, (ii) Ocean Heat Content, (iii) Ocean pH, (iv) Dissolved Oxygen concentration (v) Arctic Sea Ice extent, thickness, and volume (vi) Sea Level and (vii) the strength of the Atlantic Meridional Overturning Circulation (AMOC).

Country A For example, the shallow, speedy currents could ultimately limit how much heat the ocean can absorb, causing more of that excess heat to remain in the atmosphere. Deepening of tube-wells surface oceanic circulation results most directly in the. Surface Currents At the ocean surface, currents are primarily driven by winds. Change 5, 475-480 .
