Climate Change as a Threat to Healthcare Systems

Hitherto, climate change had been characterized primarily as a matter of science and political economy wherein the latter was lagging behind the former. As the ongoing accumulating of carbon dioxide in the atmosphere and the oceans were finally having a significant impact on the planet and us in the mid-2020s, breaking the grip of the oil industry and the related consumer demand for fossil-fuel energy proved to be too much for the UN’s annual “COP” summits because any agreements at them were nonbinding on governments. So at the commencement of the COP31 summit on November 9, 2026, the UN’s Climate Change Executive Secretary adroitly shifted the characterization of climate change to one of health, and more specifically healthcare systems—something presumably more manageable. Unfortunately, the focus on health put symptoms and effects ahead of addressing the causes of global warming.

Simon Stiell, the Secretary, labeled the “climate crisis” as “a global health crisis,” and added that it is a crisis “of pandemic proportions.”[1] But to say that health was by 2026 impacted by the effects of global warming, such as more people suffering heat-stroke during the relentless heatwaves in the E.U. during the summer of 2026, is not to say that climate change is even primarily a health crisis. Rather, the crisis is one of pollution, which in turn is fueled by profits and the related political connections that protect the polluting companies and the oil industry. Furthermore, the percentage of deaths that summer that can be traced back to global warming does not come close to being characterized as a pandemic. The rhetorical hyperbole is itself a stretch, for “(b)urning fossil fuels and human-caused climate change” were only “linked to an estimated 3.3 million deaths annually through outdoor air pollution and extreme heat, according to the Lancet Countdown 2026.”[2] That the global population was over 8 billion is enough to put 3.3 million into a realistic perspective—hardly constituting a pandemic. Moreover, Stiell’s attempt to redefine the problem of climate change as a health crisis mistakes symptoms for the underlying problem, which more accurately could be characterized as the failure of the world to hold governments accountable for missing “green energy” targets. Just because the “COP” summits have failed does not mean that climate change is or can be sufficiently addressed as a health crisis.

Whether or not climate change was “battering health systems and infrastructure” as Stiell contended, his assurance at COP31 that health would again be a central issue did not address the pressing need to attend to the causes of climate change. To be sure, he did point out the hard choice of whether to “accept ongoing fossil fuel cost pain for families, firms, and governments,” but to say that “that includes health systems” sidesteps the politically difficult choice itself.[3] Admittedly, rising “temperatures, drought and heavy rainfall can contribute to heat-related illness and mortality, wildfire smoke and poor air quality, malnutrition and food insecurity, injuries, and changing risks of water- and vector-borne diseases such as cholera, malaria and dengue,” but the key word here is contribute.[4] What about the increased flooding and fires themselves? Health is impacted from these, but so too are other things.

It is easy enough to get carried away with health effects, and even reduce the problem of climate change to health itself, especially given that getting governments to push through laws that restrict fossil-fuel-sourced energy had proved too difficult. It is much easier to urge governments to invest more in their healthcare systems. Just because the COP summits, and thus the world, had failed over a decade to get governments to clamp down on fossil-fuels so the target of 1.5C would not be breached does not mean that fortifying healthcare systems would be enough to reverse the concentration of carbon dioxide in the oceans and atmosphere. Asking whether people “have safe water after a flood” is important at a local level, but a global focus on a symptom-oriented, tertiary question effectively signals our species’ surrender on addressing the problem of climate change itself.[5] Crying wolf that a pandemic was already in progress only discredits the attempt itself to shift off the causes of climate change onto something more easily addressed by governments. 

In “recalibrating” to focus on health policy, expediency and avoidance of hard political decisions can thus be inferred. Put another way, continuing the insufficient responses to reducing carbon pollution, with the globe already expected to warm beyond the 1.5C target set by the UN within even just a few years of 2026, could be expected to bring health systems to their breaking-point anyway. Perhaps the focus of COP31 should have been on the need for enforcement power beyond the nation-state level on noncompliant governments, or on practical politics, such as setting up a global fund to support candidates for national office who campaign on curtailing fossil-fuel use sooner rather than more conveniently later. Even just expanding from a focus on healthcare systems to include ways in which governments can fortify shores from rising sea-levels and even move entire towns would be better than turning COP31 into a summit on healthcare.
