The document details how the low-lying cities of Opa-locka and Hialeah in Miami-Dade County are susceptible to inland flooding and storm surges due to their porous limestone geography and rising sea levels. It highlights the compounding effects of poverty, lack of health insurance, and food insecurity on the resilience of these majority-minority populations. Through resident testimonies, the text describes the inadequate government recovery efforts following Hurricane Wilma in 2005 and the increasing frequency of routine flooding, arguing that economic revitalization efforts must integrate climate resilience to protect property values and public safety.

Miami-Dade County faces significant risks from sea level rise, including a projected increase in tidal flooding from six events per year currently to over 380 by 2045. The document highlights threats to real estate, drinking water via the Biscayne Aquifer, electricity infrastructure, and the Everglades ecosystem. It emphasizes that pre-disaster investments are fiscally responsible, potentially saving four dollars for every dollar spent on mitigation, and calls for federal support to protect disadvantaged communities and reduce global emissions.

The report identifies 'climate equity hotspots' along the U.S. East and Gulf Coasts, where projected sea level rise and tidal flooding combine with socioeconomic risks such as poverty and minority population share. It argues that federal and state agencies must prioritize these vulnerable communities in funding and infrastructure investments to ensure an equitable response to climate change. The analysis evaluated thirty-five coastal counties across nine states and provides case studies for five specific locations, including Dorchester County, MD, and Plaquemines Parish, LA, to illustrate the challenges of environmental injustice and sinking lands.

The Union of Concerned Scientists developed a screening tool to identify coastal 'climate equity hotspots' where high climate risk overlaps with socioeconomic vulnerability. Applying this to 35 counties across the East and Gulf Coasts, the report finds that low-income and minority communities face disproportionate burdens from sea level rise and storm surges, often exacerbated by inadequate disaster recovery policies. It advocates for targeted federal funding, inclusive stakeholder engagement, and the use of actionable science to build resilience in frontline communities.

The Union of Concerned Scientists (UCS) identifies a critical need for equitable climate resilience planning in the United States, specifically for frontline coastal communities. The report introduces a screening tool that combines climate risk indicators (sea-level rise and tidal flooding) with socioeconomic data (income, poverty, race, and education) to identify 'climate equity hotspots'. Applying this tool to 35 counties across nine states, the analysis finds that the Gulf Coast and Mid-Atlantic regions face the highest risks, with Orleans Parish, Louisiana, identified as the most vulnerable hotspot. The report argues that current disaster aid often fails marginalized groups due to bureaucratic hurdles and a focus on homeowners over renters. It recommends that federal and state agencies direct funding to high-risk communities, integrate the best available climate science into planning, and increase overall funding for climate resilience.
