The public, businesses, resource managers, and policy leaders are increasingly asking for information to help them understand how and why climate conditions are changing and how they can prepare.
The National Oceanic and Atmospheric Administration (NOAA) is a primary provider of climate science, data, tools, and information used by stakeholders and citizens in decision-making contexts. These resources are supported by our strong foundation in science — including global climate observation and monitoring networks; world-renowned scientists; and state-of-the-art climate models.
NOAA is working with partners and the public to build a climate-smart nation that is resilient to climate and weather extremes, and long-term changes. Drawing upon NOAA’s foundation in science, our objectives are to:
