• The global climate is changing due to the build-up of heat-trapping gases in the atmosphere.
• Unless this build-up is slowed, the climate of the Gulf Coast region could be noticeably altered.

Research Questions
• How is the climate already changing?
• Why is it changing?• How are humans contributing to
the problem?• What are potential impacts from
climate change?

“An increasing body of observations gives a collective picture of a warming world and other changes in the climate system.”
IPCC 2001

Literature Review
• Books and articles– Global Climate Change and Its
Consequences on the Gulf Coast Region of the United States (2000) by Abdollahi and Ning
– Integrated Assessment of the Climate Change Impacts on the Gulf Coast Region (2003) Ning,Turner,Doyle and Abdollahi

The Climate of Louisiana
• Louisiana’s climate has always been variable
• Louisiana has a warm and humid climate
• Rainfall is brought by extra tropical storms in the winter & thunderstorms and tropical storms in the summer and fall.

Climate Change Risks
• Human Health,• Coastal Areas • Agriculture & Forestry, • Water Resources,• Fisheries • Wetlands

Human Health
• Climate change having the greatest direct human health
• Top 15 most notable weather disasters in the US, nine occurred in Gulf Coast states.

Coastal Areas
• Climate change will likely exacerbate coastal areas vulnerability.
• Climate change will increase the rate of erosion.

Water Resources
• Any changes in climate, such as rainfall, evaporation, groundwater recharge rates, and/or runoff patterns, will affect ecosystems and all freshwater users.
• Higher water temperatures will alter aquatic ecosystems by changing aquatic food webs and species communities

Agriculture and Forestry
• Agriculture and forestry are both enormously important industries in Louisiana
• “With changes in climate, the extent and density of forested areas in Louisiana could change little or decline by 5-15%.”
Ning & Abdollahi Global Climate Change

Fisheries
• Louisiana enjoys a lucrative fishing and seafood industry.
• As sea level continues to rise, the yield of estuarine-dependent fisheries, such as shrimp, will increase or decrease depending on the size and quality of the new habitat over time

Wetlands
• Louisiana’s wetlands are already being lost at the alarming.
• Wetlands help retain and purify water, stabilize sediments, and protect coastal areas from storm surges.

Conclusions
• It is possible to assess Louisiana’s vulnerability to a rapidly changing climate, even though extracting state-specific information from global climate model projections entails significant uncertainty. Definitely, Louisiana can play a significant role in slowing down climate change.
