Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up carbon. They also provide food and other resources, trade and migration routes.
Ocean science and monitoring helps us better understand the ocean and climate system, and make better decisions for sustainable development. We need this knowledge more than ever as we recognise how developing countries relying on ocean resources for survival are threatened by changing climate and ocean conditions.
