“Climate Change Crisis: 13 Million Americans at Risk of Becoming Climate Refugees by 2100”

According to new research, more than 13 million Americans could become climate refugees by the year 2100 if the worst sea-level rise predictions come true. The study suggests that rising seas caused by climate change could permanently flood hundreds of U.S. counties, with Miami-Dade, Florida being the hardest-hit county where 2 million people could be forced to relocate. Florida is home to about half of these potential climate refugees.

Study co-author Mathew Hauer, a demography doctoral candidate at the University of Georgia, compared the potential migration of climate refugees to the Great Migration of southern African-Americans from the South to the North. He emphasized the importance of addressing sea-level rise to prevent such a large-scale displacement of people.

The research, published in the journal Nature Climate Change, highlights the need for action at various levels of government to mitigate the effects of climate change. While the worst-case scenario of 6 feet of sea-level rise by 2100 could displace 13 million people, a better scenario with only 3 feet of sea-level rise would affect 4.2 million people.

The study analyzed census data to project future population levels in coastal areas based on historical growth rates. The researchers combined these estimates with sea-level rise projections from the National Oceanic and Atmospheric Administration (NOAA) to determine the potential impact on coastal communities.

Hauer emphasized that proactive measures can be taken to prevent mass migration of climate refugees. Local governments can implement policies such as sea walls, marsh restoration, and zoning laws to protect vulnerable areas from the effects of sea-level rise. Different regions may require tailored approaches to adaptation, depending on their specific vulnerabilities.

The study underscores the importance of addressing climate change to prevent the displacement of millions of Americans from their homes. By taking proactive steps now, communities can work towards a more sustainable future in the face of rising sea levels and other climate-related challenges.
