 Understanding climate change
Delaware is using the best available science to understand what effects we can expect and need to prepare for now and into the future.


What do we know about climate change and Delaware?

Climate change is already affecting Delaware. Over the coming years, we can anticipate even worse effects--more days of dangerously high heat, heavier precipitation, and sea level rise that leads to significant flooding.

  • Delaware Climate Change Impact Assessment
    The Delaware Climate Change Impact Assessment breaks down past and projected future climate trends in Delaware, and what these mean for Delaware's public health, water resources, agriculture, infrastructure, and ecosystems.
  • Delaware Sea Level Rise Vulnerability Assessment
    The Sea Level Rise Vulnerability Assessment takes a deep dive into the impacts that sea level rise will have on the state. The assessment includes:
    • Causes of sea level rise
    • Sea level rise trends in Delaware
    • Future scenarios for sea level rise in Delaware
    • Mapping and data for over 75 natural resources and structures that will be impacted by rising seas, like schools, fire stations, homes, wetlands, factories, wells, roads and habitats.

Tools for understanding the impacts of climate change on Delaware

These tools give users a visual of the Delaware's past, current and future conditions, and the effects of climate change across the state.

  • Delaware Climate Projections PortalThe Climate Change Projections Portal shows expected increases in average temperature.
    The Delaware Climate Projections Portal provides data on Delaware's climate indicators like temperature, precipitation, and length of growing season, tracked back to 1950 and projected up to 2100. Users can compare past climate conditions in Delaware to conditions we can expect with climate change based on the level of our greenhouse gas emissions.

    The Delaware Climate Projections Portal is hosted on the University of Delaware website:

  • Delaware Sea Level Rise Inundation Map
    The Delaware Sea Level Rise Inundation Map is an easy-to-use tool that allows you to see the areas in Delaware that are vulnerable to rising waters from sea level rise. Simply enter your address or use the zoom to explore the resources at risk from sea level rise. The slider bar in the middle of the map allows you to see an area now and after a projected sea level rise scenario. 

    The Delaware Sea Level Rise Inundation Map is hosted here:
