Welcome to the AMS Policy Program's memo project. Here you can find brief introductions (no more than 2 pages) to key topics in weather, water, and climate. The views expressed are those of the author alone and do not necessarily reflect the views of the American Meteorological Society, its members, or sponsors.
Water is simultaneously a resource and a threat. It is centrally important to every aspect of socioeconomic wellbeing and water becomes a hazard when there is too much, too little, or if the quality is poor. The opportunities and challenges posed by water are especially acute at the coasts, which are both major resources and often highly vulnerable to extreme events. Coastal communities are also particularly sensitive to changes in land use, population distributions, and climate. This memo identifies seven ways to enhance coastal risk management.
The weather, water, and climate community relies on the radio frequency spectrum for two vital functions: (1) to observe the earth (e.g., with satellites, weather radars, and wind profilers) and (2) to transmit data about the earth system to meteorologists, hydrologists, emergency managers, and other scientists throughout the country. These uses of radio frequencies benefit a wide range of social and economic sectors by supporting operational services that protect life and property and by helping advance scientific understanding of the earth system.
Earth observations, science, and services (Earth OSS) inform and guide the activities of virtually all economic sectors and innumerable institutions underlying modern civilization. This AMS Policy Program memo describes Earth OSS and illustrates how Earth OSS are a fundamental component of efforts to meet basic human needs including food, shelter, energy, health and safety. At the same time, the opportunities for societal benefit from Earth OSS are increasing.
As a public issue, climate change boils down to four overarching findings: 1) climate is changing, 2) people are causing climate to change, 3) human caused climate change poses serious risks to society, and 4) we have numerous options for managing climate change risks.
