United States In Danger: Study Shows Big Cities In America Would Be Flooded By The Sea

United States In Danger: NASA recently published alarming images revealing the threat of rising sea levels to the East Coast of the United States. These images depict major cities like New York and Baltimore facing submersion due to the encroaching sea.

The research, conducted by a team of scientists funded by NASA and working at Virginia Tech’s Earth Observation and Discovery Laboratory, highlights the rapid pace at which this geological issue is unfolding. It poses a significant risk to vital infrastructure, agricultural land, and precious wetlands relied upon by millions of people residing along the coastline.

The findings underscore the urgent need for action to mitigate the impacts of rising sea levels on coastal communities. Failure to address this issue could lead to widespread devastation and displacement of populations living in vulnerable areas. The research serves as a stark reminder of the looming threat posed by climate change and the importance of proactive measures to safeguard coastal regions from the adverse effects of sea-level rise.

Using satellite data and GPS sensors, scientists conducted a thorough analysis to track the movement of the coastline. They aimed to understand how the land beneath major cities like Norfolk, Baltimore, New York, and Virginia has been shifting over time.

Their findings revealed a concerning trend: between the years 2007 and 2020, the land on which critical infrastructure is built experienced significant sinking. This means that the ground beneath these cities has been gradually lowering, posing a risk to the stability of buildings, roads, and other structures.

The sinking of the land raises serious concerns about the long-term viability of these coastal cities. As the ground continues to subside, it could exacerbate the threat posed by rising sea levels, leading to increased flooding and erosion along the coastline.

This research underscores the importance of monitoring and understanding changes in the Earth’s surface to better prepare for the challenges posed by climate change. It highlights the need for proactive measures to protect coastal communities and their infrastructure from the impacts of sinking land and sea-level rise.

Every year, the land along certain parts of the coastline has been sinking by about 1 to 2 millimeters on average. This gradual sinking is a cause for concern, especially as it affects not just one area but spans across counties in Delaware, Maryland, South Carolina, and Georgia. In some of these counties, the land is sinking at rates two or three times faster than the average.

Scientists have noted that the sinking is particularly pronounced in wetland areas, where the land is subsiding by more than 3 millimeters annually. This accelerated sinking poses a significant risk to the ecosystems and habitats found in these wetlands.

Moreover, the encroachment of saltwater into these areas is disrupting forests and draining the land. This intrusion of saltwater into previously freshwater environments is causing further displacement and degradation of natural habitats, exacerbating the challenges faced by coastal ecosystems.

The findings highlight the urgent need for conservation efforts and proactive measures to address the sinking land and its impacts on coastal environments. It is crucial to safeguard these vulnerable areas and mitigate the effects of sinking land and saltwater intrusion to protect the biodiversity and resilience of coastal ecosystems.

Apart from wildlife, it’s not just animals feeling the impact. Approximately 897,000 structures, which include highways and airports, are situated on the sinking land. This means that vital infrastructure essential for transportation and other functions is at risk due to the land’s depletion.

The confirmation of this risk comes from a study published in PNAS Nexus. This study builds upon previous research conducted by a lab at Virginia Tech, further solidifying the understanding of the threats posed by sinking land along the coastline.

The findings underscore the critical need for action to address the sinking land issue. Protecting not only wildlife but also essential infrastructure is paramount to ensuring the safety and functionality of coastal regions. It highlights the importance of implementing measures to mitigate the impacts of sinking land and safeguarding the integrity of structures vital for the well-being of communities along the coast.

New NASA images reveal the continued sinking of the Mid-Atlantic region, mapped using data collected by satellites from the United States, Japan, and Europe. This sinking is attributed to the historical impact of the Laurentide Ice Sheet, which began retreating around 12,000 years ago, leading to the submersion of the region over time.

According to Leonard Ohenhen, a scientist from Virginia Tech, the research team utilized satellite radar data to study how land subsidence exacerbates the vulnerability of communities, properties, and infrastructure to coastal hazards. The main findings of their analysis indicate that an area spanning from 2,000 to 74,000 square kilometers, with a population ranging from 1.2 to 14 million people, is experiencing sinking at a rate of 1 to 2 millimeters per year.

These findings highlight the significant impact of land subsidence on coastal regions, posing a threat to both human settlements and critical infrastructure. As the land continues to sink, it increases the susceptibility of coastal communities to hazards such as flooding and erosion.

The research underscores the importance of understanding and addressing the factors contributing to land subsidence to mitigate the risks faced by vulnerable coastal areas. It emphasizes the need for proactive measures to protect communities, properties, and infrastructure from the adverse effects of sinking land, ensuring the resilience and sustainability of coastal regions in the face of ongoing environmental changes.

Scientist Ohenhen also mentioned that sinking land is affecting over half of the infrastructure in numerous big cities, making them more prone to flooding and other coastal dangers.
