For over two millennia, Alexandria, Egypt, a city synonymous with ancient knowledge, cleopatra, adn vibrant culture, has stood resilient against the tides of history.But today,Alexandria faces a new,insidious enemy: the rising sea,fueled by climate change.
The situation in Alexandria is becoming increasingly dire, serving as a stark example of the threats facing coastal communities worldwide, including those right here in the United States.With a dramatic increase in building collapses in the past 20 years, Alexandria is sounding an alarm that we in the U.S. can’t afford to ignore.
The Crisis unfolding in alexandria
recent data paints a grim picture. Over the last two decades, rising sea levels have contributed to the collapse of approximately 280 buildings in Alexandria. Alarmingly, the rate of destruction
has surged from roughly one per year to as manny as 40 annually, according to research published in *Earth’s Future*.
Studies indicate that at least 7,000 more structures in Alexandria are vulnerable. Tragically, between 2014 and 2020, building collapses resulted in 85 deaths. These figures highlight not only the physical destruction but also the human cost of climate change.
“The true cost of this loss extends far beyond bricks and mortar,” said Essam Heggy, study co-author. “We are witnessing the gradual disappearance of historic coastal cities, with Alexandria sounding the alarm.”

The issues in Alexandria are, sadly, mirrored in communities across the U.S. Let’s take a look at the factors contributing to this crisis.
The Science Behind the Rising tide
The National Oceanic and Atmospheric Administration (NOAA) reports that global sea levels have risen by approximately 8-9 inches since 1880. A significant portion of this rise,about 4 inches,has occurred as 1993. this acceleration is directly linked to rising global temperatures, which cause thermal expansion of water and the melting of glaciers and ice sheets.
The implications are severe. If pollution levels remain unchecked,sea levels could rise by another 7.2 feet by 2100, imperiling millions living in coastal regions. This isn’t a far-off threat; it’s a rapidly approaching reality.
In the United States, cities like Miami, New Orleans, and New York City are already grappling with the effects of rising sea levels. Increased flooding, coastal erosion, and saltwater intrusion into freshwater sources are becoming increasingly common.These challenges mirror those faced by Alexandria, highlighting the global nature of this crisis.
Coastal erosion, especially exacerbated by stronger storms, is a major concern. Barrier islands, like those along the Outer Banks of North Carolina, are vital for protecting the mainland but are steadily being eroded.This erosion threatens not only homes and infrastructure but also critical ecosystems.
Think about the impact on the insurance industry. As coastal properties become more vulnerable, insurance rates are skyrocketing, making it unaffordable for many to live in these areas. This creates a ripple effect, impacting property values and local economies.
Saltwater intrusion is contaminating drinking water sources in many coastal communities. Florida, as an example, is facing significant challenges with saltwater seeping into it’s freshwater aquifers, threatening the water supply for millions of residents. This issue is compounded by increased demand for water due to population growth.
Addressing the crisis: A Multi-Faceted Approach
While the situation is dire, it’s not hopeless. There are numerous strategies being explored and implemented to mitigate the impact of rising sea levels, both in Alexandria and in the U.S.
in Alexandria, experts suggest elevating buildings on stilts or reinforced foundations to minimize seawater intrusion. Urban planners are also considering relocating residents from high-risk areas to safer locations. These measures are aimed at protecting lives and minimizing infrastructure loss.
Here in the U.S., similar strategies are being implemented. Such as, in some coastal communities, homes are being elevated to protect them from flooding. in Miami, pumps are being installed to remove floodwater from streets. However, these are often seen as band-aids to a much larger problem.
On a broader scale, addressing the root cause of rising sea levels is crucial. This means reducing greenhouse gas emissions by transitioning to clean energy sources,curbing methane gas pollution,and protecting coastal wetlands.
Investing in resilient infrastructure is equally significant. This includes building stronger seawalls, restoring coastal wetlands, and implementing better stormwater management systems. The Dutch, for example, have long been leaders in water management, and their expertise can provide valuable lessons for the U.S.
Though, the biggest roadblock is frequently enough political will. Implementing meaningful climate action requires bipartisan support and a long-term commitment. This can be a challenge in a politically polarized surroundings.
Consider the debate around the Green New Deal. While it proposes enterprising solutions to address climate change, it has faced significant opposition, highlighting the political divisions surrounding this issue.
Despite these challenges, individual actions can make a difference.Reducing your carbon footprint by driving less, using less energy, and making enduring consumer choices can contribute to a larger collective effort.
A Call to action
Alexandria’s plight serves as a wake-up call. As Essam Heggy stated,Our study challenges the common misconception that we’ll only need to worry when sea levels rise by a meter. Coastlines globally… are already changing and causing building collapses at an unprecedented rate.
The choices we make today will determine the future of our cities, coastlines, and cultural heritage. It’s time to demand action from our leaders, invest in resilient infrastructure, and make sustainable choices in our daily lives. The future of coastal communities, both in Alexandria and the United States, depends on it.
What are the most effective strategies for protecting U.S.coastal communities from the impacts of rising sea levels?
Interview: Dr.Aris Thorne on Rising Sea Levels and the Fate of Coastal Cities
Introduction
Good day, and welcome to Archyde news. Today, we have dr. Aris Thorne, a leading coastal geologist and expert on the impacts of climate change on sea levels. Dr. Thorne, thank you for joining us.
dr.Thorne: Thank you for having me. It’s a crucial time to discuss these issues.
Alexandria’s Predicament and the U.S. Concerns
Archyde News: Dr. Thorne, we’ve been reporting on the dire situation in Alexandria, Egypt, where rising sea levels are causing widespread building collapses. How does this reflect on the potential challenges for coastal cities within United States?
Dr. Thorne: Alexandria serves as a clear warning. The rate of building collapses is accelerating, reflecting what we can expect in the U.S. Coastal erosion, increased flooding, and saltwater intrusion are already becoming more frequent here, especially in major cities such as Miami, New Orleans, and New York City. What’s happening in Alexandria is a harbinger of things to come.
The Science Behind sea Level Rise
Archyde News: The science is clear, but can you explain the primary drivers behind rising sea levels?
Dr. Thorne: Certainly. The primary drivers are thermal expansion of water, as the oceans absorb more heat due to rising global temperatures, and the melting of glaciers and ice sheets. The NOAA reports an increase of about 8-9 inches as 1880,with an acceleration since 1993. If we don’t curb pollution,we could see a 7.2-foot rise by 2100.
Impacts on Coastal Communities
Archyde News: What are the most critical impacts that U.S. coastal communities are facing right now?
Dr. Thorne: We’re seeing increased flooding, wich damages homes and infrastructure. Coastal erosion is a major threat. Saltwater intrusion is contaminating freshwater sources, posing significant risks to water supplies. The insurance industry is also significantly affected.Property values are declining or have plummeted, which has resulted in exorbitant insurance rates, making it unaffordable for many to live in these areas.
Addressing the Crisis: Solutions and Obstacles
Archyde News: What are the potential solutions that you see as viable, both for individual communities and on a broader scale? And what are the biggest roadblocks to implementing these solutions?
Dr. Thorne: There are multiple strategies. Elevating buildings, reinforcing foundations, and relocation of residents are strategies local to communities. On a larger scale, we must reduce greenhouse gas emissions by transitioning to clean energy, curbing pollution, and restoring coastal wetlands.Investing in resilient infrastructure, like seawalls and better stormwater management, is also key.
The biggest roadblock,is frequently enough political will,but that can be offset by increasing awareness. The Green New Deal highlights deep divisions over this issue. The general population needs to be aware of climate change, as this will drive the political powers that be to make meaningful change and mitigate these effects. Every individual can take action by reducing their carbon footprint.
Looking to The Future and a Call For Action
Archyde News: Dr. Thorne, what is your message to our readers regarding the urgency of this situation?
Dr. Thorne: We can’t afford to wait.Alexandria is showing us what will happen if we don’t act now. It’s not just about protecting property, it’s about protecting our heritage, culture, and lives. The choices we make today will determine the future of our coastal communities. We need to demand action from our leaders, invest in resilient infrastructure, and make sustainable choices in our daily lives.
Archyde news: Dr. Thorne, thank you for your insights.
