Climate change looks different depending on where you are in the world. In Delaware, climate change primarily takes the form of sea level rise, increasing temperatures and more frequent intense storms, including heavy precipitation and flooding.
While the earth’s climate has changed naturally throughout its history due to various influences, modern research has shown that the climate is changing more rapidly than it has in the past — and it is extremely likely that human activities are the major driver of that change.
Over the coming years, it is projected that Delaware will face higher temperatures, more high heat days, increased heavy precipitation events and sea level rise.
The impacts from each of these threatens the state’s industries, infrastructure, natural resources and health of residents.
Sea Level Rise
Heavy Precipitation and Flooding
Precipitation in Delaware over the last century has averaged 45 inches per year. That is expected to increase about 10 percent by 2100. The number of very wet days, 2 inches or more of rainfall in 24 hours, is also projected to increase. Additionally, an increase in the frequency and intensity of heavy precipitation events is projected over the next century.
