Yves here. If anything, this post seems to be understating how climate change threatens hospitals. Floods and other severe weather does not just affect facilities directly, but it can also prevent staff from coming in. In New York City, the subways flooded during Hurricane Sandy and were closed for a week plus. On top of that, lower Manhattan suffered a protracted power outage. What happens if hospital staffers who expect to charge EVs at home are stuck due to lack of power and not enough juice in their car to get to work?
The article also describes the impact of the new, seemingly pervasive problem of scorching heat.

Within a month, health care leaders in two other major U.S. cities would confront similar tests. On the West Coast, historic rainfall cut power to a hospital in Los Angeles, while in New York, torrential downpours caused a power outage and electrical damage at a hospital in Brooklyn — both incidents prompting emergency evacuations.
The recent hospital closures in the United States illustrate a larger trend that’s already in motion. Human-driven climate change has increased the risk of damage to hospitals by 41% between 1990 and 2020, according to a December 2023 report published by XDI, or Cross Dependency Initiative, an Australian climate risk data company.
Thousands of health care facilities around the world are buckling under the effects of climate change, a trend experts predict will worsen in the coming decades as extreme weather increases pressure on hospital infrastructure and simultaneously creates more demand for care.
Expert Warnings
In a May 2024 report, the United Nations Population Fund estimated that nearly 1,500 hospitals are located in low-lying coastal areas of Latin America and the Caribbean that already endure life-threatening storms and flooding. More than 80% of hospitals in Aruba, Bahamas, Cayman Islands, Guyana, and Suriname are in these danger zones.
Hundreds of hospitals in the U.S. are at risk from flooding, according to a 2022 study by Harvard researchers. Along the Atlantic and Gulf Coasts, hospitals in Delaware, Florida, Louisiana, New Hampshire, Massachusetts, Maryland, New Jersey, New York, and Pennsylvania were most at risk of flooding caused by a Category 2 hurricane.
On the other side of the globe, surging floods and landslides shuttered 12 health care facilities in five provinces in southern Thailand in 2023. The year before that, Pakistan’s devastating floods limited the function of at least 1,460 health care facilities, about 10% of the country’s total.
Looking at the climate risk to roughly 200,000 hospitals from flooding, fires, and cyclones, the XDI researchers estimated that by the end of this century, one in 12 hospitals worldwide could be at risk of total or partial shutdown due to extreme weather.
Some regions are more vulnerable than others. The report estimated more than 5,800 hospitals in South Asia alone — an area that includes India, the world’s most populous country — would be at high risk of shutting down under a 4.3 degrees Celsius global warming scenario.
Other regions are not immune, however. Over half of hospitals in the Central African Republic and more than one-quarter of hospitals in the Philippines and Nepal would face the same fate.
Compounding the Pressure with Extreme Heat
Summer 2023 was the hottest on record. Scorching temperatures brought deadly heat waves and wildfires that tore through forests and surrounding towns and cities — all potentially impacting human health as well as the hospitals and clinics where people seek care.
“The northern hemisphere just had a summer of extremes — with repeated heat waves fueling devastating wildfires, harming health, disrupting daily lives, and wreaking a lasting toll on the environment,” World Meteorological Organization Secretary-General Petteri Taalas said in a statement.
That summer, in Arizona, for example, extreme heat put pressure on power grids and spurred an influx of people in need of medical care for heat stress.
A 2021 study found that heat-related emergency room visits in Taiwan rose by 50% on days that reached a wet-bulb temperature — which accounts for both heat and humidity — of at least 89.6 degrees Fahrenheit. At that level, it’s more difficult for sweat to evaporate and therefore harder for people to cool themselves.
Looking Ahead to Future Risk
In the coming decades, health care infrastructure will face increasing strain from the impacts of extreme weather and temperature rise — power outages, hospital closures, and damage to buildings.
At the same time, demand for care could grow. Climate change is expected to worsen more than half of known human pathogenic diseases over the next 25 years, expanding the range of fungal infections and increasing the risk of virusesand mosquito-borne diseases. Meanwhile, extreme heat will likely increasingly send people to the hospital.
Making significant changes to the way hospitals operate may seem daunting, but facilities can start small in their adaptations and create solutions unique to their needs.
An example of this approach can be found in Vietnam. About half of all hospitals in that country do not have a reliable source of water, whether that’s due to droughts, floods, or creeping saltwater intrusion. A result: patients often have to bring their own. Faced with this major obstacle to care, three rural hospitals in Vietnam embarked on projects to get more climate resilient by addressing water availability. The institutions each found innovative ways to obtain more water using solutions like rainwater catchment and storage systems, saline filtration, and better infrastructure to capture nearby streamflows.
“Unfortunately, we can expect climate change to increasingly threaten water supplies at health care facilities throughout Vietnam, so it is critical to act quickly with adaptation measures,” Angela Pratt, a WHO Representative in Vietnam, said in a news release.
As climate change impacts push health care systems into higher levels of risk, it’s vital that hospital leadership teams globally begin shaping plans for climate resiliency related to infrastructure and personnel to safeguard health care on a changing planet.

This is not only going to apply to hospitals but all emergency services such as police, fire departments, ambulance stations and any other emergency service. The track record is not good about thinking about the vulnerability of where those emergency services are located. I once saw a doco on the effects of the big one shaking loose in California and mentioned was the fact that a major police station was located direct over a fault line. The best thing would be perhaps is to decentralize these services into multiple locations but unfortunately the trend over the decade has been to shut down smaller stations & hospitals and to have huge ones instead for economy of scale I guess.
I live in a small city within the Cascadia subduction zone and the only hospital on our side of the river just closed. We are the largest population in this end of the valley and there are still two major hospitals but both are across the river (and I5) and only accessible by bridges – not a great scenario and our local politicians seem powerless to influence the corporations who decide these things.
This is not a new issue – those who remember Katrina may also remember “5 days at Memorial”. Only hard choices and as near as I can tell most planners haven’t learned the lessons from that tragedy.
As the cost of medical and dental care skyrockets and as physicians retire, as medical and dental practices and hospitals are bought up by private equity firms or consolidated into giant ‘healthcare’ corporations, as insurance companies crapify healthcare service and leech government subsidy monies from the few threadbare ‘healthcare’ safety nets, as the u.s. population grows older and the Corona flu and other diseases erode public health … I am not sure the threats of climate change are the worst threats to u.s. ‘healthcare’.
In any case, the concluding suggestion:
“As climate change impacts push health care systems into higher levels of risk, it’s vital that hospital leadership teams globally begin shaping plans for climate resiliency related to infrastructure and personnel to safeguard health care on a changing planet.”
sounds like very weak tea to me. I guess my first question — what “hospital leadership teams”? Next I wonder how climate resiliency for “infrastructure and personnel” can add to and grow hospital profitability — which I believe is the only concern that worries “hospital leadership teams” other than what’s for lunch and how much will my pay bonus be for this quarter.
Weakened by comprehensive, multi-generation parasite infestation, the US healthcare infrastructure is particularly vulnerable to any disruptions in basic support systems, as maintenance and redundancy don’t survive the MBAs.
