With increased concern regarding climate change and its effects on local environments, the State of Delaware's Department of Natural Resources and Environmental Control (DNREC) conducted a climate projections study for Delaware. The DNREC study provides predictions of changes in Delaware climate throughout the 21st century. This page shows some of the climate projections from the DNREC study, including the number of nights annually with a temperature above 80º F; the number of days annually with temperature above 90º F, 95º F, and 100º F; and the average daily high temperature projections.

The State of Delaware's Department of Natural Resources and Environmental Control (DNREC) worked with leading climate scientists to create climate projections for Delaware. To create the climate projections, researchers coupled over 100 years of Delaware weather station observations with climate model simulations of projected future climate conditions through the end of the 21st century.

Not all communities feel the impacts of climate change equally. Low-income communities, for instance, may struggle with high energy bills during the hottest parts of the summer, while elderly and disabled individuals are more vulnerable to the health effects of extreme heat waves. The Social Vulnerability Index (SVI) is a resource created by the CDC to identify communities that may need greater support.
