Towards Earth System Predictions: The Importance of Ocean Observations

Society requires specific information on climate changes and its consequences at the global and regional scales. In the past, considerable progress has been made towards the realistic simulation of important Earth system processes. Model projections for the next century have been used as an important input to the assessments conducted by the Inter-governmental Panel for Climate Change (IPCC). There is now a growing demand for shorter-term climate predictions. This represents a major challenge for the scientific community, and specifically for the newly created Climate Services that provide authoritative information on climate-related questions. Decadal predictions models require initial conditions based on observations, specifically on ocean data. It is therefore crucial that the ocean community improves its ocean observing and monitoring systems, which will soon become a key component of operational climate prediction systems. In addition to physical quantities, biogeochemical variables should also be routinely measured.
