  • Countries most affected by weather disasters do not spend more on weather services
    on May 24, 2017 at 6:17 pm

    Countries hit hardest by weather-related disasters do not necessarily spend more on commercial weather and climate information services that assist in preparing for these events, a new study finds. Identifying countries for which this is true and improving the design and delivery of weather and climate services in these locations could lead to better decision-making regarding risks and challenges, ultimately helping to save lives, protect infrastructure, and move people out of poverty. […]
