ClassX Video Lessons Youtube Channel Curiosity Stream The Dangers To Coastal Cities Like Miami | Breakthrough
Imagine living in a city where the ocean is slowly creeping into your streets. This is becoming a reality for places like Miami and Miami Beach, where rising sea levels are reshaping the landscape. These areas are popular because of their beautiful coastal locations, but they are also at risk due to climate change, which is causing sea levels to rise and changing tidal patterns. This gradual rise in sea levels could have serious local impacts over time.
Sea level rise is not something that happens overnight. It’s a slow-moving disaster that unfolds gradually, with water appearing in places it shouldn’t be. According to William Sweet, an oceanographer with NOAA (the National Oceanic and Atmospheric Administration), the global average sea level is rising by about 1 inch every 8 years. However, in Miami Beach, the situation is more severe, with water levels rising almost five times as fast. Bruce Mau, the city engineer of Miami Beach, estimates a rise of about 1 foot every 20 years. In the next 40 years, Miami Beach could see a 2-foot rise, which would be very damaging.
Scientists from Climate Central, using data from NOAA, have developed a tool to visualize how sea level rise could affect Miami Beach over time. With a 2-foot rise, much of the west side of Miami Beach could be flooded. A 4-foot rise would inundate more areas, including parts of Miami’s Financial District. A 6-foot rise could submerge sections of the MacArthur Causeway, isolating parts of Miami Beach, and an 8-foot rise would impact Miami International Airport.
Residents of Miami Beach are already experiencing the effects of sea level rise. During certain times of the year, high tides, known as king tides, cause flooding even on sunny days. These events are becoming more frequent and severe. On his first day on the job, Bruce Mau witnessed such flooding, which motivated him to focus on preventing future occurrences.
Miami Beach is a barrier island, with its highest points along the Atlantic Ocean. The lower areas, originally mangrove swamps, are more prone to flooding. The city has invested $400 to $500 million in building water pumps and raising defenses to combat sea level rise. As climate change continues, water levels increase each year, requiring ongoing adaptation.
To protect against future sea level rise, Miami Beach has raised its seawalls to new standards, aiming for 50 more years of protection. Despite alarming predictions, discussions about climate change focus on data like carbon dioxide emissions, global temperatures, ice melt, and sea level rise. These factors vary by region and are interpreted differently by scientists.
Dr. James Hansen, a former NASA climate scientist, warns that current models may underestimate the severity of future conditions. If fossil fuel emissions remain high, we could see sea levels rise by several meters, leading to significant financial costs and the displacement of millions of people.
Despite these challenges, Miami Beach is determined to adapt and thrive. The city is using new technologies and strategies to combat rising sea levels. For example, in Sunset Harbor, a previously low-lying street was raised by almost 2.5 feet to extend its lifespan by another 30 to 50 years. The goal is to keep Miami Beach vibrant and economically viable for residents and tourists well into the future.
As a city engineer, I am confident that we can overcome these challenges and continue to live and thrive in coastal cities like Miami Beach.

Increasingly familiar, these dramatic images foreshadow the everyday consequences of sea level rise flooding in coastal cities already being reshaped by rising waters. Miami and Miami Beach are areas right on the coast, which is why people want to live there. However, we need to be aware that the data indicates sea levels are rising, and this rise is likely to worsen due to climate change, which is altering tidal patterns and providing glimpses of what’s to come—gradual and potentially devastating local impacts.
Sea level rise isn’t detected in one big wave; it’s much more deceptive. It’s a slow-motion disaster unfolding before our eyes, with flooding occurring where water is not supposed to be. We won’t wake up one day to find everything underwater. William Sweet, an oceanographer with NOAA (the National Oceanic and Atmospheric Administration), studies sea level rise, its causes, and impacts. He points to a global average rise of 1 inch every 8 years. Bruce Mau, the city engineer of Miami Beach, says he’s designing solutions for water levels rising almost five times as fast, estimating about a 1-foot rise every 20 years. Within the next 40 years, we expect about 2 feet of sea level rise in Miami Beach, which is very detrimental.
Using information from various sources, including elevation data from NOAA, scientists from the nonprofit Climate Central developed an interactive tool to visualize the potential impacts of sea level rise over time, street by street. At 2 feet, much of the west side of Miami Beach is flooded, including the intersection at Alton and 10th. A 4-foot rise inundates much of what remains and floods parts of Miami’s Financial District. A 6-foot rise would leave sections of the MacArthur Causeway underwater, isolating whatever remains of Miami Beach, while a rise of 8 feet would impact Miami International Airport.
Miami Beach already knows what it means to wade through sea level rise. Residents have experienced elevated high tides during certain times of the year, known as king tides. These events are clear evidence of incremental increases. We are witnessing sea level rise impacts, with high tide flooding events growing in severity, frequency, and extent. Mau’s first day on the job coincided with one of these events, where water rushed into city streets on a sunny day, leading him to focus on stopping the flooding.
Miami Beach is a barrier island, with the original barrier along the Atlantic Ocean being relatively high. The backside, originally mangrove swamps, was filled and is the lowest part, making it most susceptible to flooding. The city has committed $400 to $500 million to combat sea level rise by building water pumps and raising defenses. With the ongoing issue of climate change and sea level rise, we see an increase in water levels every year, necessitating changes to adapt to future conditions.
Miami Beach has raised the levels of its seawalls to meet new standards, aiming for an additional 50 years of protection. Despite dire projections, discussions surrounding climate change focus on related data points: emissions of carbon dioxide, global temperatures, glacial and polar ice melt, and sea level rise. The rise is not uniform; it varies regionally and is subject to interpretation and differing analyses.
Former NASA climate scientist Dr. James Hansen, now leading a climate science program at Columbia University, suggests a greater probability for more extreme conditions, including higher sea levels sooner than anticipated. His team concluded that current models do not accurately represent reality, indicating that if fossil fuel emissions continue at high levels, we could see sea level rise of several meters, leading to significant financial costs and potential displacement of millions.
Back on the front lines, Miami Beach has no plans to surrender. The city believes it can meet the challenge of rising sea levels through adaptation and new technologies. For example, in Sunset Harbor, the city elevated a street that was previously one of the lowest, raising it by almost 2.5 feet to extend its lifespan by another 30 to 50 years. The goal is to keep Miami Beach a vibrant, economically viable city for residents and tourists alike long into the future.
As a city engineer, I have complete faith that we can mitigate and survive these challenges.
