Is Miami really sinking? It’s a question that’s been on a lot of people’s minds lately, especially with the city’s increasing vulnerability to flooding.
The science behind the rising seas is complex, but in a nutshell, it has to do with a combination of factors including melting ice caps, ocean circulation, and the Earth’s natural wobble.
All of these factors contribute to a rise in sea level, which means that Miami is indeed at risk of being swallowed by

The Problem
The causes of sea level rise
Over the past century, the global average sea level has risen by about eight inches. Sea level rise is caused by two main things – the expansion of water as it warms, and the melting of glaciers and land-based ice.
As water warms, it expands. This has contributed about half of the eight inch rise in global sea level over the past hundred years. The rest is from melting glaciers and ice sheets.
The rate of sea level rise has been increasing over the past few decades, and is now accelerating. The expansion of water as it warms is responsible for some of this acceleration, but the main cause is increased melting of glaciers and land-based ice, like in Greenland and Antarctica.
As human-caused climate change continues, we can expect the rate of sea level rise to continue to increase. Storms will become more severe, flooding will become more common and coastal communities will be increasingly at risk.
The effects of sea level rise
As the Earth’s climate continues to warm, melting ice sheets and glaciers are causing the world’s oceans to rise at an accelerating pace. Most of Miami is just six feet above sea level, and even a small amount of sea level rise can cause major flooding problems.
During high tide, water from the ocean often spills over into Miami’s streets and causes what is known as “sunny day flooding.” This flooding is expected to become more frequent and more severe as sea levels continue to rise.
In addition to sunny day flooding, Miami is also at risk from more powerful storms and hurricanes. Storm surge, which is the wall of water that a hurricane pushes ahead of it as it makes landfall, can be devastating. Hurricane Irma caused record-breaking storm surge in Miami in 2017, leading to widespread damage and flooding.
As sea levels continue to rise and storms become more powerful, the risk of major flooding events in Miami will only increase.
The Solutions
As the sea level rises, so does the risk of flooding. In order to combat the effects of climate change, we must first understand the science behind it. This article will explore the Solutions to the problem of rising seas. We will discuss the pros and cons of each solution and what needs to be done in order to implement them.
What can be done to prevent sea level rise?
Mitigation
The long-term solution to rising seas is to stabilize the level of greenhouse gases in the atmosphere and stop the warming that’s driving the entire process. That will require a major effort to decarbonize the global economy, phasing out fossil fuels and shifting to renewable energy sources.
But even if we take aggressive action to stop climate change, we’ll still see some amount of sea level rise in the coming centuries as a result of the warming that has already occurred. That means we also need to adapt to the changes that are already underway.
Adaptation
While mitigation will stop the problem from getting worse, we also need to adapt to the changes that are already happening. That means making changes in our own lives and communities to become more resilient in the face of flooding and other impacts of sea level rise.
Some adaptation strategies include:
-Elevating buildings and critical infrastructure
-Building seawalls, levees, and other coastal defenses
-Restoring natural buffers like wetlands and reefs
-Changing building codes and land-use regulations
-Improving emergency preparedness and response
What can be done to adapt to sea level rise?
What can be done to adapt to sea level rise?
1. Shoreline protection: This can be done through engineering structures like seawalls, levees, and breakwaters that protect against flooding and erosion.
2. Land use planning: Developing floodplain maps and regulating development in vulnerable areas can help reduce the risk of damage from flooding.
3. Elevating structures: This is often done through the use of “pilings” which are driven into the ground to support a structure as it is raised above the base flood level.
4. Wetland restoration: Wetlands act as natural buffers against flooding and erosion. The restoration of these ecosystems can help mitigate the effects of sea level rise.
5. Improving drainage: Increasing the capacity of drainage systems and properly maintaining them can help reduce the risk of flooding.
The Controversy
For years, Miami has been slowly sinking. But as the seas continue to rise, the pace of sinking has begun to speed up. As a result, the city is now facing an existential threat from the very waters that made it possible in the first place.
The arguments for and against sea level rise
There are two main arguments for why sea level rise is happening: 1) the oceans are getting warmer, and 2) ice is melting and adding water to the oceans.
The first argument is based on the fact that water expands as it warms. So, as the oceans get warmer (due to climate change), they take up more space and cause the sea level to rise.
The second argument is based on the fact that there is ice at the poles (in Antarctica and Greenland) and in glaciers around the world. As this ice melts, it adds water to the oceans and causes the sea level to rise.
There are also two main arguments for why sea level rise is NOT happening: 1) measurements of sea level rise are inaccurate, and 2) natural processes like air pressure and ocean currents can cause sea levels to fluctuate without any long-term change.
The first argument is based on the fact that there are many different ways to measure sea level, and these measurements can be affected by things like tides, weather, and waves. So, some people argue that we can’t trust any single measurement of sea levelrise.
The second argument is based on the fact that natural processes like El Niño (a warm ocean current) can cause sea levels to rise in some parts of the world while natural processes like La Niña (a cold ocean current) can cause them to fall in other parts. So, some people argue that we can’t see any long-term trend in sea levelrise because these natural processes are always happening.
The politics of sea level rise
Denialism of human-caused climate change is often fueled by political interests, and the issue of sea level rise is no different. In the United States, Republicans have been more likely than Democrats to downplay the risks of climate change and sea level rise. For example, in 2012, then-Republican presidential nominee Mitt Romney said that he was not “convinced” that human activity was causing the planet to warm.
More recently, some Republican leaders have started to acknowledge the reality of climate change and its effects on sea level rise. In 2017, for example, Florida Republican Senator Marco Rubio said that he did not think anyone could deny that sea levels were rising.
Still, there are plenty of politicians and interest groups who continue to deny or downplay the risks of sea level rise. This stance often leads to policies that do not adequately address the problem, which in turn puts people and property at risk.
The Future
Climate change is real, and it’s happening right now. The Earth is getting warmer, the ice is melting, and the seas are rising. This is not some distant threat. It’s happening here, and it’s happening now. And it’s going to get worse.
The potential impacts of sea level rise
Impacts from sea level rise will not be evenly distributed. Poor and socially vulnerable people living in low-lying, coastal areas are expected to suffer the greatest consequences, due to their limited ability to prepare for and adapt to changes.
In addition to the direct impacts of flooding and erosion, other consequences of sea level rise include:
-Saltwater intrusion into freshwater aquifers
-Increased costs for infrastructure (e.g., coastal roads and bridges)
-Declining biodiversity
-Human displacement
The possible solutions to sea level rise
As the effects of climate change and sea level rise become more and more pronounced, cities around the world are starting to look for ways to adapt. Miami, as a coastal city, is particularly vulnerable to the effects of rising seas.
One way to protect against rising seas is to build barriers, such as seawalls or levees. These structures can help to keep water from flooding low-lying areas. Another option is to create artificial islands or floating city platforms. These could provide space for homes and businesses that would be safe from flooding.
Another possible solution is to desalinate water from the ocean. This process removes salt and other minerals from seawater, making it safe to drink. Desalination plants are already in use in some areas of the world, but they are expensive and require a lot of energy.
In the end, the best solution to rising seas may be to prevent them from happening in the first place. This means reducing greenhouse gas emissions and slowing down climate change. It will take effort from individuals, businesses, and governments around the world, but it is essential for protecting our planet – and our cities – from the devastating effects of sea level rise.
