As part of the Migrant Clinicians Network, my colleagues and I have treated many kinds of migrant over more than two decades: a farm worker who needs prenatal care who must travel every three weeks with the harvest; an asylum seeker struggling with insulin-dependent diabetes who is trying to escape war and violence; an immigrant who needs to travel back home in the midst of his tuberculosis treatment. But we are beginning to see a new type of patient — climate migrants — who I fear we will be seeing more of in the years to come, especially as the Trump administration seems to be ignoring the effects of climate change.

The Camp Fire devastated the town of Paradise, Calif. As it climbed over the hill toward the town of 26,000, many clinicians at the Feather River Hospital were instructed to prepare to evacuate. The fire moved with such speed that, just minutes after preparations began, the evacuation became mandatory.

Horror stories of the rapid evacuation litter social media: a patient in a hospital gown in the back seat of a clinician’s car; a mother who had just given birth and was still immobilized by anesthesia trapped in an ambulance that had caught on fire; ambulances, trapped by fire on the roads, having to return to the hospital only to discover it had burned down; frantic goodbye calls to loved ones.

Clinicians quickly began triage in the pop-up refugee camps in the nearby town of Chico. First they treated people for respiratory problems and minor injuries in the Walmart parking lot. Then they fought outbreaks of norovirus in the churches and empty box store buildings that served as evacuation centers. And now, two months later, they are still caring for thousands of the newly homeless who have nowhere to go.

The fires were the result of an amalgam of complicated factors, including private and public forest management, a complex urban-wildland interface, and drought combined with a topography, biosphere, and wind patterns primed for fire. But as with Hurricane Maria, Superstorm Sandy, and fires across the West, climate change pushed this disaster to a new, severe, and deadly extreme.

It also created climate migrants.

In Central America, widespread gang violence, political instability, and devastating poverty leave families at the brink of starvation, while globalization, decades of previous migration, and modern technology make migration seem more plausible. But it’s the climate-induced droughts and disasters, longer and more intense than are typical, that are making migration a necessity.

A week after the California fire, and in the midst of continued migration to the border, the Trump administration quietly released the “Fourth National Climate Assessment, Volume II: Impacts, Risks, and Adaptation in the United States.” It emphasizes how climate change is the great amplifier: not just pushing our extreme weather to be more extreme, but also making our social inequalities even more unequal. Vulnerable populations, the report noted, are particularly at risk: “Populations including older adults, children, low-income communities, and some communities of color are often disproportionately affected by, and less resilient to, the health impacts of climate change.”

Climate migrants aren’t made only by natural disasters. They’re made from a complex fabric of social, political, environmental, and economic factors that is torn when a climate-strengthened disaster appears, be it stronger hurricanes, rising sea levels, devastating droughts, or increased heat. Climate change is pushing people to move for their immediate or long-term health and well-being.

Health systems need to be flexible enough to serve climate migrants as they are forced from their homes. Most, for example, currently have trouble transferring medical records or scheduling appointments across state lines with ease. But those fleeing disaster will need quick and nimble systems to serve them.

We must reformulate our health systems to accommodate climate migrants, whether they are arriving at the border because their crops failed or they have developed acute health issues arising from disaster. With no connections and few resources to help them connect to care, they must be able to find health services while in a new town.

Services like the Migrant Clinicians Network’s Health Network can help. Through it, a clinician can sign up a patient, and a case manager will help that patient find services in his or her new location, assure the transfer of medical records, and even link the patient with needed auxiliary services like transportation to a health center. Such services save lives, but as climate change advances, we need to be prepared to implement them at a larger scale.

Clinicians also have another major role to play: to help stop the advancement of climate change in the first place. According to the National Climate Assessment, “While mitigation and adaptation efforts have expanded substantially in the last four years, they do not yet approach the scale considered necessary to avoid substantial damages to the economy, environment, and human health over the coming decades. … Future risks from climate change depend primarily on decisions made today.”

Now, more than ever, clinicians whose core values include helping improve the health of entire communities must work and advocate to stop climate change so they can help people avoid becoming climate migrants in the first place.

Ed Zuroweste, M.D., is the chief medical officer for the Migrant Clinicians Network and assistant professor of medicine at Johns Hopkins University School of Medicine. Migrant Clinicians Network, with five offices around the U.S., including Chico, Calif., is a nonprofit focused on health justice for the mobile poor.

  • What humans do to limit climate change is the work of ants, compared to the simply natural climate evolution caused by solar flares and other such events so immeasurably more powerful than we can ever be. It is cocky of us to think we can stop the process. We have to tackle this differently, be smarter in learning to work with those events and in finding solutions. Stop the over-build / jeopardizing of hot dry hill sides, curb overblown residential expansion. No swimming pool in every yard, and be much, much more water-conservation oriented. Build loads of desalination plants that curb the rise of seawater levels, that provide water to make dry lands fertile, and water at hand for natural disasters. Work with the changes, rather than fight them.

    • So desalination of the ocean to stop the rise of seawater is not fighting climate change?? Any idea how much energy it takes to desalinate water?, enough to lower the seas? Where will that Energy come from, and how much energy will it take to deliver all of this fresh water (uphill) to where it is needed, or to turn it back to ice and ship to polar areas to where it belongs? Only to melt again.

      Generating energy by present methods (breaking carbon bonds, and generating CO2) is the problem. Science has advanced to the point that we know where the Carbon Atoms in the newer and excess (last 150 years) atmospheric CO2 is coming from. It is carbon bonded by ancient life forms, hundred of millions of years ago. Rightly called “fossil fuels”. We the humans, are what takes it from the ground to the air, faster than the oceans or other natural forces can remove it. We have to slow rising temperatures before we reverse it.

      Yes natures forces are powerful, like the sun, winds, gravity and ocean tides (lunar power). Figure out how to capture and use those powers, and maybe we can start desalination to generate fresh water, and lower oceans. We can only START that process in our little lifetimes. Surrendering or denying won’t work.
