The document outlines NOAA's plans to establish a National Climate Service (NCS) to better serve the needs of stakeholders and the public regarding climate information. The NCS will work to advance understanding of climate change and predict climate impacts through improved climate science, observations, assessments and decision support tools. Key priorities include increasing understanding and preparation for climate impacts on water resources, coastal resilience, marine ecosystems and climate extremes. The NCS will also work to inform climate mitigation options. Meeting challenges such as establishing partnerships, ensuring credible science-based information and balancing user and science needs are discussed.
