A Policy Statement of the American Meteorological Society
(Adopted by the AMS Council 10 August 2012)
The purpose of this statement is to characterize the benefits of climate services to the United States and the international community, and to foster improved climate services and delivery of those services to users by encouraging: 1) communication, cooperation, and collaboration among all sectors; 2) the scientific, operational, and financial success of all of the sectors involved in climate services; and 3), the leveraging wherever possible of resources among all sectors.
Climate services (CS) may be defined as scientifically based information and products that enhance users’ knowledge and understanding about the impacts of climate on their decisions and actions.1 These services are made most effective through collaboration between providers and users.
The climate services enterprise in the United States comprises a wide variety of entities (not listed here in entirety). NOAA provides core capabilities in support of the delivery of climate services, via the National Weather Service (NWS), the National Environmental Satellite Data and Information Service (NESDIS), and through the Regional Climate Centers (RCC). Other federal agencies also provide, on a smaller scale, climate services at national and local levels. State Climate Offices (SCOs) are the primary deliverers of climate services at the state government level.
In addition, universities (for example, NOAA’s RISAs, and Land Grant Colleges’ cooperative extension offices), nongovernmental organizations (NGOs), and private-sector businesses large and small, play important roles in developing and delivering climate services. Sample lists of some climate services are available at http://www.climate.gov (government);http://www.sab.noaa.gov/Reports/CPTF_RPT_FINAL.pdf (private firms); andhttp://library.duke.edu/research/subject/guides/ngo_guide/ngo_database.html (NGOs).
Climate services support society’s continuing effort to be productive and prosperous, and to manage impacts from atmospheric, oceanic, cryospheric, and land phenomena, over periods ranging from days (climate-related extreme events) to decades, and over regions, from highly localized to the entire planet. Some examples of CS include, 1) past climate: data stewardship and rescue, reanalysis, and historical climate summaries; 2) present climate: observations, monitoring, climate summaries, reports, and studies, to estimate the type, range, and likelihood of variations of climate variables relevant to planning and applications at national, state, and local levels; and 3) future climate:forecasts and projections of climate conditions for use in mitigation, planning, and adaptation.
The roles of the public, private, and academic sectors in CS are sometimes difficult to distinguish. Strong relationships and frequent communication among sectors are essential to ensure that responsibilities are coordinated, unnecessary redundancies are minimized, and issues among members of the enterprise are resolved effectively. Organizations such as the AMS play a key role in fostering such communication. Since no single sector can satisfy the demand for CS on its own, it is clear that society is best served when the sectors work together.
The existing suite of CS is the result of sustained support over many decades by governments (state and local), universities, non-governmental organizations and philanthropic foundations, and the private sector. Manifestations of weather and climate variability, including extreme temperatures (e.g., heat waves, cold spells), drought, and flooding, are of obvious importance to agriculture, our national forests and other ecosystems, and water resources; and to the energy, insurance, construction, transportation, and recreation industries, public health, and national security.
Assessing the value of climate services to the public and the private sector is complicated by the inherent difficulty of placing a dollar value on a “public good.” Also, private companies are understandably reticent to describe in detail their use of and profit from such services.2 Quantitative information on climate impacts and the value of climate services would help inform, guide, and justify public and private investment in CS infrastructure and capabilities.
