America's Preparedness Report Card 2015

View Map

South Carolina faces growing threat levels from extreme heat, wildfire, inland flooding, and coastal flooding between now and 2050. South Carolina has taken strong action to address its current climate risks and the state has begun to take steps to understand its vulnerability to climate change-related risks. The state could do more by developing an adaptation plan and implementing resilience strategies.

Extreme Heat

South Carolina is projected to see its annual average number of heat wave days quadruple by 2050. The state has taken strong action to address its current risks, primarily through hazard mitigation planning. However, the state has not produced a detailed, statewide vulnerability assessment for extreme heat nor developed an adaptation plan that covers it.


Grades were assigned only when threats were identified as priorities for that state. For details, see the methodology.


South Carolina has nearly 3 million people living in areas at elevated risk of wildfires, and the state is taking strong action to address its current wildfire risks. It has also begun to take some action to address its future risks. It has taken steps to evaluate its vulnerability to future wildfires and developed an adaptation plan.

Inland Flooding

South Carolina has taken many steps to prepare for its current inland flooding risks and impacts. The state is also tracking the occurrences of flooding and associated impacts, and has published information about climate change-related inland flooding.

Coastal Flooding

South Carolina receives a D grade for its coastal flooding preparedness due to the lack of steps taken to address its future risks. The state has taken almost no action in planning for and adapting to its future coastal flooding risks.
