A landmark new study has found that Atlantic storms have become deadlier as the planet warms – and are disproportionately killing people of color in the US.
According to reports, about 20,000 excess deaths – the numbers of observed rather than expected deaths – occurred in the immediate aftermath of 179 named storms and hurricanes which struck the US mainland between 1988 and 2019. This is even as more than two thirds of the total excess death toll – and 17 of the 20 deadliest storms – have occurred during the past 15 years, as ocean-heating fossil-fuel emissions have driven increasingly intense hurricanes.
The highest death counts were in counties with majority Black, brown and Indigenous residents, suggesting historical government neglect plays a role in the loss of life in the aftermath of tropical storms, according to the study published in Science Advances.
Tropical storms and hurricanes wreak billions of dollars of damage every year especially on the Atlantic and Gulf coasts. Yet this is the first study to quantify the storm-related excess death toll over time nationwide – data which could save lives.
“Cyclones don’t hit the whole country. They tend to hit places which have more Black, Indigenous and Latin people who’ve been historically underserved and overburdened through racism, and it’s these socially vulnerable communities who are bearing the brunt of post-cyclone excess deaths,” said Robbie Parks, assistant professor of environmental health sciences at Columbia University’s public health school and lead author.

Speaking further, he said “For the first time we have comparable death counts over time, which from a federal government and climate justice perspective can be used as levers for action and resource allocation for evacuations, rebuilds and resilience,”.
Parks and his colleagues estimated the number of excess deaths after tropical storms in all affected areas in the US, breaking down the data for every county, year, and storm, using death registration data across four decades. Island states and territories including tropical storm-prone Hawaii and Puerto Rico – where almost 3,000 people are estimated to have died after Hurricane Maria in 2017 – were not included due to data gaps.
According to available data, the deadliest storm was Hurricane Katrina in 2005, with 1,491 excess deaths including 719 in Orleans parish, a majority Black county. This was followed by 309 excess deaths after Hurricane Rita in Harris county, Texas; 185 deaths in Broward county, Florida, after Hurricane Matthew in 2016; and 178 in Nassau county, New York, after Hurricane Sandy in 2012.
Previous research has shown that post-storm deaths can result from several major causes such as injuries, infectious and parasitic diseases, cardiovascular complications and respiratory conditions. Overall 93% of post-hurricane excess deaths – and 70% of those after a named storm – have occurred since 2005 as the impact of global heating has accelerated.
