Chart of Global Sea Surface Temperature

The ocean—the major heat, carbon and water reservoir of the world—is a crucial regulator of the Earth's climate. More than 93% of the enhanced atmospheric heating since the 1970s has been absorbed by the ocean, even affecting the deep ocean. The absorption of a disproportionate amount of heat from global warming and of the rapidly increasing emissions of carbon dioxide—which raises the levels of ocean acidity—has significant consequences for humanity, marine species and the ecosystems of the ocean.
