In the US, climate change is forcing millions of people to leave their homes due to rising sea levels, drought and other impacts. Between 2000 and 2020, about 3.2 million Americans were forced to relocate due to risks linked to climate change, according to a recent analysis.
Climate abandonment zones in Sun Belt states like Florida and Texas affect communities at risk of economic decline, with property values falling and local services diminishing.
Jeremy Porter, head of climate impacts research at the First Street Foundation, said flood risk has a major impact on population change. This affects property values, neighborhood structures and commercial vitality, both positively and negatively.
In particular, Bexar County, Texas, and several other counties are among the areas experiencing heavy population loss. Areas such as Will County in Illinois and El Paso County in Texas are also experiencing migration due to flood risk.
Extreme weather conditions, such as increased flooding and large wildfires, expose around 36 million properties across the US to high climate risks.
