Climate Change Impacts on South Carolina

Over the last decade, SC coal-fired power plants produced an average of 39,200,000 tons of carbon pollution each year.

Over the last decade, SC coal-fired power plants produced an average of 34,200,000 tons of carbon pollution each year.

The earth’s climate is changing because of excess carbon dioxide pollution in the atmosphere, generated when fossil fuels like coal, oil, and natural gas are burned. This extra carbon traps more heat, like a greenhouse, which explains why 2000 to 2009 was the hottest decade ever recorded and there have been over 390 consecutive months with hotter-than-average global temperatures. Modern civilization developed in a stable climate and we have built our economy and way of life accordingly. Changes to our climate means that we are facing emerging hardships and vulnerabilities as the impacts of climate change unfold.

Some impacts from climate change include extreme storms, flooding from sea level rise, heat waves, and drought. These impacts have consequences for public health, safety, the economy, the environment, and our way of life.

Fortunately, we can protect against the worst impacts by limiting carbon pollution with energy efficiency and using more clean renewable energy, like solar and wind instead.


It is difficult to link any one event directly to climate change, and it is important to recognize that most climate data is regional or even global in scope. However, decades of expert research and centuries of historical records can be compared with recent trends to illustrate how climate change is already impacting parts of the Southeastern United States. These impacts, combined with possible future impacts, are both cause for concern and the imperative for action.

South Carolina’s most treasured landscapes, such as our salt marshes, and all the activities they support—boating, fishing, shrimping—are threatened by climate change.

South Carolina’s most treasured landscapes, such as our salt marshes, and all the pastimes they support—boating, fishing, shrimping—are threatened by climate change.

  • Some of South Carolina’s most treasured places are flooding and eroding away due in part to sea level rise from climate change. Sea levels rise because as the Earth warms, sea water expands and on-land glaciers melt. Sea level rise compromises places like the historic Charleston peninsula, and our many beach communities. Sea level rise also jeopardizes South Carolina’s coastal tourism economy that generates $7.7 billion and supports 80,000 jobs annually. Seas are projected to rise by between 8 inches and 8 feet throughout the 21st century alone.
  • Hurricanes are getting more intense in a warmer world, tending more toward category 4 and 5 storms. Coupled with flooding from sea level rise, the liability to our coastal communities is great. Insurance will likely continue to get more expensive as more extreme weather disasters take place.




Clean energy, such as solar, wind, and energy efficiency, produces no pollution and provides jobs in our struggling economy. Studies show that the United States could easily generate 80% of its power from clean sources by 2050. Energy efficiency can dramatically reduce the amount of power we use in our homes and businesses and lower our bills. In South Carolina, our offshore wind resource alone could produce more than 100% of the electricity we currently use each year. Solar power is unlimited energy from the sun, free for the taking if our state policies are revised to level the playing field between solar and more traditional, polluting power sources like coal and nuclear.


Some energy sources have greater risks associated with their use. Old, inefficient and dirty coal power plants must be retired to reduce levels of pollution that trigger asthma attacks and heart and lung disease, put mercury in our water, and cause climate change. Nuclear power plants emit less carbon than coal but are extremely expensive to build, require large amounts of water to operate, generate dangerous, highly radioactive waste and can have devastating consequences should an accident occur. Our coast is too precious to be compromised by spills from offshore drilling. Clean energy is a positive alternative to each of these risky energy sources.

1) Find and Contact Your Legislators – National and state-level climate and energy policies are imperative to ensure protection from the worst impacts of climate change and to secure the benefits of clean energy. Find your Washington, D.C. and Columbia legislators’ contact information here, and contact them to tell them we must lead the way in climate and energy policies that:

  • Invest in job-creating energy efficiency and clean energy
  • Limit carbon pollution
  • Hold polluters accountable and end fossil-fuel subsidies
  • Preserve and strengthen the Clean Air Act

2) Support Our Work & Become a Member of SACE Today – Be a part in helping South Carolina usher in the clean energy economy, clean up our environment, and securing the world we ought to pass down to future generations.
