Impacts and Adaptation Options in the Gulf Coast

The central and western U.S. Gulf Coast is increasingly vulnerable to a range of potential hazards associated with climate change. Hurricanes are high-profile hazards that threaten this region with strong winds, heavy rain, storm surge and high waves. Sea-level rise is a longer-term hazard that threatens to exacerbate storm surges, and increases the rate of coastal erosion and wetland loss. Loss of wetlands threatens to damage the fragile coastal ecosystem and accelerates the rate of coastal erosion.

These hazards threaten to inflict economic and ecological losses in this region, as well as loss of life during destructive hurricanes. In addition, they impact vital economic sectors, such as the energy and fishing industries, which are foundational to the local and regional economy. Impacts to these sectors are also realized on a national scale; Gulf oil and gas is used throughout the country to heat homes, power cars, and generate a variety of products, such as rubber and plastics, while seafood from the region is shipped to restaurants across the country.

This report reviews observed and projected changes for each of these hazards, as well as potential impacts and adaptation options. Information about the scale and relative importance of the energy and fishing industries is also provided, as well as insight into potential vulnerabilities of these industries to climate change. This report also identifies some adaptation options for those industries.
