Ep 4. Miami

Miami is the fourth episode of season one of the series Sinking Cities. The show explores how cities around the world are grappling with the consequences of rising sea levels and sinking land due to climate change. Miami is one of America's most popular tourist destinations and is home to some 2.7 million people. However, it is one of the cities most at risk from rising sea levels. In this episode, the show takes a closer look at how Miami's local authorities, urban planners, and residents are dealing with the challenges posed by climate change.

The episode begins with aerial shots of Miami's stunning coastline, highlighting the city's beaches, ports, and high-rise buildings. The narrator explains how sea levels in Miami have risen by almost a foot over the past century, which makes it one of the fastest disappearing cities in the world. As the water level inexorably rises, Miami is struggling to keep its residents safe, its economy afloat, and its infrastructure from collapsing.

The show introduces viewers to several experts on climate change and the impact of rising sea levels. They explain that Miami's geography makes it particularly vulnerable to flooding. The city lies on top of a limestone bedrock that is porous and prone to erosion. Coastal buildings in Miami have foundations that go straight down to the bedrock, without any pilings to support them. This makes them susceptible to damage or even collapse if the water level rises too high.

Next, the episode explores how Miami is preparing for the worst-case scenario. The local government has launched several initiatives to try and mitigate the risks posed by climate change. The narrator highlights some of these measures, such as the city's use of pump stations to drain water from the streets during floods, the installation of flood barriers, the creation of artificial reefs to combat coastal erosion, and the use of "green roofs" to promote urban biodiversity and reduce runoff.

The show then turns to some of the challenges that Miami faces in adapting to climate change. One expert notes that rising sea levels not only put people's homes and livelihoods at risk but also pose a threat to public health. As the water level rises, saltwater can seep into freshwater sources and contaminate them. This can lead to the spread of diseases and affect the local ecosystem. The episode also explores the economic impact of climate change on Miami, specifically on the city's maritime economy. As the water level rises, Miami's ports are likely to become less functional, which could have major knock-on effects on the global supply chain.

Towards the end of the episode, the show speaks to some of the residents of Miami who are directly affected by climate change. It explores their personal experiences of flooding, rising insurance premiums, and the uncertainty of the future. The episode also looks at how communities in Miami are adapting to the changing climate, such as through the use of sustainable materials, rain gardens, and canal cleanups.

Overall, Miami is a poignant and informative episode that highlights the complex challenges that cities around the world face due to climate change. The show combines aerial footage of Miami's beautiful skyline with interviews with experts, government officials, and residents. It also provides insight into the ways in which Miami is using innovative solutions to try and mitigate the risks posed by rising sea levels.
