By Jenny Ralph Moses,<\/strong> Florida State University\u00a0News<\/a><\/strong>
Routine high-tide flooding in coastal communities could lead to thousands of deaths among older adults by the end of the century, according to a new study co-authored by Florida State University researcher Mathew Hauer.
Published in The Lancet Planetary Health<\/a><\/small>, the study projects that without significant adaptation, premature deaths among adults aged 65 and older linked to high-tide flooding could increase 43-fold by 2100.
Unlike storm surges from major hurricanes, high-tide flooding happens regularly and is often viewed as a nuisance rather than a danger. But researchers found even shallow flooding on roads can delay emergency medical care for older adults during time-sensitive emergencies such as cardiac arrest.
\u201cWhen we think about climate change threatening people\u2019s lives, we picture hurricanes and heat waves,\u201d Hauer said. \u201cWhat we found is that the routine, ankle-deep flooding people have learned to live with is on track to kill more older adults than storm surge does in these same coastal areas. It\u2019s a quiet, cumulative form of climate mortality, and until now nobody had put a national number on it.\u201d
The research team, which included Hauer from the FSU College of Social Sciences and Public Policy\u2019s<\/a> Department of Sociology and Center for Demography and Population Health<\/a>, found that flooding creates significant traffic disruptions that obstruct emergency medical access. This is particularly dangerous for time-sensitive conditions where every minute of delay significantly reduces survival rates.
Researchers identified three major findings:
The findings are a wake-up call for the Sunshine State, which stands at the epicenter of the issue.
The study identified Florida as the nation\u2019s most vulnerable state because of its large older population and extensive low-lying coastline.
By 2060, Florida could account for 24% to 38% of all high-tide flooding deaths in the coastal contiguous U.S., with an estimated 360 to 1,590 annual fatalities.
\u201cFlorida has twin threats of an older population and a large, low-lying coastal zone,\u201d Hauer said. \u201cSo, the demography, the geography and climate change all combine to account for a large percentage of these anticipated deaths.\u201d
Researchers said the projected death toll could be significantly reduced through infrastructure improvements and planning. Implementing protective measures, such as elevating roads or building new health care facilities in accessible locations, could reduce premature deaths by 57%.
The researchers recommend three critical steps for coastal communities:
The study concluded that the economic costs associated with these deaths exceed many other climate-related impacts, making health care infrastructure a priority for policymakers.
\u201cThe deaths show up when an ambulance can\u2019t get through and the adaptive infrastructure to prevent these are things we already know how to do,\u201d Hauer said. \u201cSimple things like raising roadways, better sited-hospitals, and other changes could make a significant impact on reducing this anticipated mortality. An ounce of prevention today is worth a pound of cure tomorrow.\u201d
The study was funded by the U.S. Environmental Protection Agency and included collaborators from Arizona State University, Industrial Economics and the International Food Policy Research Institute.
