Assess Climate Risks in New Orleans – 2025

Understanding Our Climate Future

New Orleans has always lived with water, surrounded by the Mississippi River, Lake Pontchartrain, and the Gulf of Mexico. But in 2025, the conversation around climate change is no longer a distant warning—it’s a reality shaping our everyday lives, neighborhoods, and city planning.

As we navigate sea-level rise, stronger hurricanes, heatwaves, and increasing rainfall, it’s more important than ever for residents, businesses, and property owners to assess climate risks and make informed decisions.

Key Climate Risks Facing New Orleans in 2025

1. Sea-Level Rise and Land Subsidence New Orleans continues to sink, while global sea levels rise. Together, these increase the risk of chronic flooding, especially in low-lying neighborhoods such as Gentilly, New Orleans East, and parts of Algiers.

2. Intensifying Storms, Hurricane seasons have become more active and unpredictable. Building resilience into your home or business—through storm shutters, elevated structures, and flood insurance—is no longer optional.

3. Extreme Heat Summer temperatures are climbing, bringing health risks, higher energy costs, and added strain on vulnerable communities. Green infrastructure, tree planting, and reflective roofing materials can help mitigate the heat island effect.

4. Drainage and Flooding Heavy rainfall events are increasing in intensity and frequency. The city’s pumping and drainage systems are being upgraded, but local flooding remains a concern. Knowing your flood zone and elevation is essential.

How to Assess Your Climate Risk in 2025

• Use Online Tools: Check FEMA flood maps, NOAA’s Sea Level Rise Viewer, and climate risk score platforms to assess your property's exposure.

• Talk to Local Experts: Urban planners, environmental scientists, and even your real estate agent can provide insights tailored to your area.

• Prepare Financially: Ensure you have adequate flood insurance, even if you're not in a high-risk zone. Explore grants or incentives for climate-resilient upgrades.

• Get Involved: Support policies and projects focused on climate adaptation—from levee improvements to green infrastructure initiatives.

Looking Forward

New Orleans’ culture, beauty, and resilience are unmatched, but facing climate risk head-on is essential for preserving that legacy. Whether you're a lifelong resident, a newcomer, or someone thinking about investing in the Crescent City, understanding our changing environment is the first step toward a more secure and sustainable future.
