Here’s why sea walls alone won’t save Florida from climate change

Florida is one of the states in the US that has been most impacted by climate change. Rising sea levels, extreme weather events, and other climate-related factors have caused significant damage to the state’s economy and infrastructure. While sea walls have been proposed as a solution to protect Florida’s coastal areas from flooding, they are not a panacea. This article explores why sea walls alone won’t save Florida from climate change.

The Impact of Climate Change in Florida

The impact of climate change on Florida has been devastating. The state has experienced more than its fair share of extreme weather events, including hurricanes, flooding, and heatwaves. Rising sea levels caused by global warming have led to flooding of low-lying areas, and the loss of valuable coastal property. Furthermore, the impact of climate change on Florida’s infrastructure has been significant. Coastal roads and bridges have been damaged, and water treatment plants have become increasingly vulnerable to flooding.

Why Sea Walls are Not Enough

While sea walls can help to protect coastal areas from rising sea levels, they are not enough on their own. Sea walls have a limited lifespan, and their effectiveness decreases over time. Furthermore, they are expensive to build, and require ongoing maintenance. This means that sea walls are not a long-term solution to the problem of rising sea levels caused by climate change.

Another problem with sea walls is that they are only effective at protecting against slow, gradual sea level rise. However, they are not effective at protecting against sudden, extreme weather events such as hurricanes. In fact, during Hurricane Ian, elevated storm surges made coastal flooding and damages even deadlier. So, while sea walls can help to protect against slow sea level rise, they are not a solution to the impact of extreme weather events.

The Importance of Reducing Carbon Emissions

The most effective way to address the challenge of climate change in Florida is to reduce carbon emissions. According to the National Academies, global average sea level is increasing due to melting land ice and the expansion of warming seawater, both of which are caused by a warming planet. This means that reducing carbon emissions is critical to slowing down the rate of sea level rise in Florida.

To achieve this goal, Florida must embrace renewable energy and promote policies and programs that reduce carbon emissions. This will require significant investment in new infrastructure and technologies, but it is the only way to address the challenge of climate change in the long term.

The Importance of Setting an Upper Limit on Sea-Level Rise

Setting an upper limit on sea-level rise is critical to protecting the viability of Florida’s economy. If we aggressively reduce climate pollution, we can limit sea-level rise to about 1 to 2 feet by the end of the century. Beyond 2 feet, adapting gets exponentially more expensive.

Building sea walls and raising roads is only a temporary fix. Florida must set an upper limit on the amount of sea-level rise the economy can withstand. To achieve that limit, businesses, communities and governments must embrace renewable energy and promote policies and programs that reduce their carbon footprint.

Conclusion

Florida is facing a significant challenge from climate change. Rising sea levels, extreme weather events, and other climate-related factors have caused significant damage to the state’s economy and infrastructure. While sea walls have been proposed as a solution to protect Florida’s coastal areas from flooding, they are not enough on their own.
