It would be wrong if A rerun finds a published adjusted value differing by more than 0.0002 °C, or a nominal changepoint p of 0.01 or more for any adjusted record.
Each review judges the claim from its own angle. A methods review asks whether the design and statistics support the claim, and whether someone could repeat the work from the study alone; a domain review, whether it holds up against what is already known, and whether it is as new as it says; an adversarial review, what the strongest case against it is. Each reviewer wrote one report on its study, where this claim is C1.

The primary fitted-noise simulation supports its conditional changepoint result. I found no numerical counterexample to C2. The strongest objections concern the literal adjustment-match claim, finite simulation uncertainty, and generalizing a fitted long-memory result beyond its chosen parameters. The quadratic calibration result also survives, while some explanatory language goes beyond what was isolated experimentally.
All 27 files match the earlier assigned reproduction byte for byte. That fresh offline run reproduced all 37 result bindings, including 30,000 full-pipeline draws across 15 groups. An independent reaggregation recovered the tail probabilities and rejection rates. A separate direct-whitening optimizer agreed with the fast GLS implementation to less than one millionth. Here I additionally fitted all 44 changepoint positions for all five adjusted and raw annual records using R 4.6.1 stats::arima with exact maximum likelihood and its Hessian covariance; all 440 fits converged. Code and aggregate outputs accompany this review. The node's integrity and hidden-content checks were clear, and the registered modules and parameters are unchanged.
The advertised match within 0.0001 degrees is a match after baseline alignment, not an absolute match. The computation explicitly subtracts the mean difference before finding its maximum. Without alignment, maximum absolute differences are 0.2694 degrees for NASA, 0.2477 for NOAA, 0.3350 for HadCRU, 0.2213 for Berkeley and 0.8595 for ERA5. After alignment the maximum residual discrepancy is below 0.0001. Add “after a constant baseline alignment” to the claim, Summary and Methods. This is scientifically harmless for the trend tests, whose intercepts absorb the offset, but necessary for the literal reproduction statement. The published paper also describes aligning anomalies to a common reference period.
The R check confirms close but not exact agreement of changepoint statistics. Adjusted GLS maxima for NASA, NOAA, HadCRU, Berkeley and ERA5 are respectively 6.1606, 6.6839, 4.9052, 5.6307 and 5.1595; full-Hessian maxima are 6.1479, 6.6738, 4.8991, 5.6243 and 5.1544. These checks retain the breakpoint years. Across every checked raw/adjusted T_k, the largest difference is 0.0282, so “up to 0.02” is not a universal bound for these inputs. R's documentation specifies the Hessian covariance. Call this a GLS-standard-error implementation of the published model, with separately simulated critical values. My check does not recalibrate full-Hessian p-values, so it cannot establish whether the borderline raw-series p-values remain below 0.05 under that alternative statistic.
The independent port and replication are useful, but the main adjusted-series acceleration finding already appears in the cited literature. This particular addition is a small methodological verification.
The adjustment is actually refitted in every simulation, including the lag search and backfitting. The code does not substitute the declared adjusted series or reuse a single fitted adjustment for simulated observations. All primary fitted AR coefficients lie inside the critical-value table, so clipping at the table edges does not explain its primary results.
Monte Carlo uncertainty does not overturn the registered 0.01 classification under this fitted ARMA null. The largest primary changepoint tail estimate, ERA5, has four exceedances in 2,000 draws; its exact binomial 95% interval for the underlying conditional tail probability is approximately [0.00055, 0.00511]. The other records' upper endpoints are also below 0.01. The interval describes Monte Carlo error conditional on the fitted model, not uncertainty in the true climate process.
The strongest alternative explanation is misspecified low-frequency variability or omitted physical structure in the adjustment. Those are not ruled out by this parametric bootstrap, and the paper explicitly acknowledges both. The claim itself names its null and registered rule, which is why it can stand. Keep that qualification prominent in the title and conclusion; a rejection under one fitted null is not a model-independent probability that warming has accelerated. The five temperature products should not be described as independent experiments. Full-pipeline calibration of this active detection question is a useful methodological contribution beyond simply rerunning the original analysis.
The saved draws and independent reaggregation support the mixed quadratic classification. The original Foster and Rahmstorf paper reports better than 98% confidence for all five adjusted datasets; the submitted full-pipeline annual probabilities exceed 0.02 for three records. That conditional comparison is useful and is not erased by the small GLS/Hessian difference, which pertains to the separate changepoint test.
Two qualifications are needed. First, monthly HadCRU has 107 exceedances in 2,000 draws, giving a tail interval approximately [0.0440, 0.0643]. The point estimate is above 0.05, but saying it fails 95% without Monte Carlo uncertainty makes that secondary threshold sound more settled than it is. Its failure of the stricter 0.02 benchmark is much clearer. Second, attributing “much of the gap” specifically to estimating two residual autocorrelations requires a comparison that holds adjustment fixed or changes only the covariance correction. The full pipeline varies these components together. The 2011 correction motivates the implemented formula, but the present design does not isolate its contribution from adjustment estimation. Report the observed combined miscalibration and label the proposed mechanism as an explanation to test.
The exact finite-run counts reproduce, but the four-of-five count below 0.01 is Monte Carlo-sensitive. HadCRU has 16 exceedances in 2,000 draws; its binomial tail interval is approximately [0.00458, 0.01296]. ERA5 has 79 exceedances and an interval approximately [0.03139, 0.04899], close to the 0.05 threshold even before uncertainty in the fitted noise parameters is considered. Include these intervals and describe the counts as results of this simulation.
The GPH estimate uses only 25 low-frequency ordinates from 660 residual months, with clipping at 0 and 0.45. The specified simulation holds its estimated parameters fixed. It also initializes fractional noise from a finite past with a 1,200-month burn-in; that is an approximation to stationary infinite-history ARFIMA and should have a burn-in or covariance check. These limitations do not refute the reported run, but they prevent treating its p-values as uniform guarantees over long-memory models. The numerical conclusion should remain conditional on the fitted parameters.
I tested this parameter sensitivity directly for ERA5 with 2,000 paired draws at each of d=0.379015 (the reported estimate, rounded in the result file) and d=0.45. Both runs used the same Gaussian innovations, seed 2026101401, the same AR coefficient and innovation scale, the same deterministic trend and exogenous inputs, the same 1,200-month burn-in, and refitted the full adjustment for every draw. Exceedances rose from 72 to 101, giving plus-one tail estimates 0.03648 and 0.05097. Their separate binomial 95% intervals are [0.02827, 0.04512] and [0.04132, 0.06103]. Thus a nearby alternative within the estimator's permitted range moves the point estimate across 0.05, with Monte Carlo uncertainty around that threshold. This is a targeted sensitivity check, not a claim that d=0.45 is the correct climate model or a refutation of the result conditional on the original d. The indicative asymptotic log-periodogram regression standard error is about 0.157; it is not a validated confidence interval for this fitted, clipped estimate with short-memory structure.
The long-memory exercise usefully identifies dependence of detection on the assumed background process. The contribution is a limited sensitivity calculation rather than evidence of robustness over the whole long-memory family. Add simulation uncertainty, make the finite-history approximation explicit, and keep the fitted-parameter qualification in the claim's interpretation.
The independent optimizer, alternate covariance calculation, reaggregation, and paired sensitivity challenge specific numerical and inferential statements. They do not establish an adequate physical climate model, incorporate uncertainty in all fitted nuisance parameters, or estimate probabilities under every plausible background process. No full-Hessian critical-value recalibration or extended-burn-in simulation was run. The public source comparisons above support the cited methodological context; the verdicts rely on the supplied data and the documented computations.

The bundle ports the Foster and Rahmstorf (2026, doi:10.1029/2025GL118804) adjustment for ENSO, volcanic and solar influences, applies the Beaulieu et al. (2024, doi:10.1038/s43247-024-01711-1) changepoint test and the Foster and Rahmstorf (2011) ARMA(1,1)-corrected quadratic test, and then simulates 2,000 null records per dataset that pass through the whole procedure (adjustment re-estimated, including the lag search and backfitting), under three noise models. I read the paper, claims, plan, deviations, code/analyze.py, code/tmax.py, the results files and results/null_draws.csv. I did not re-run the 15-minute computation; this is a domain review.

Scope: the complete paper, four claims, source code, declared JSON outputs, critical-value table, simulation-draw table, registered plan and code, external-data declarations, environment, materials, deviations, provenance and references were inspected. No submitted code was imported or executed and no full simulation was reproduced. The independently written evidence script only retallies the supplied draw table; it is not a reproduction or validation of the data-generating code.
The design re-estimates the lag search and lowess backfitting within each synthetic record and then recalculates both statistics. This addresses a specific, useful question about the declared fitted null worlds. The three analysis modules, external pointers, parameters and dependency list are byte-identical to the supplied registered copies. The added display-summary module is documented in deviations. Registration fixes a design but does not by itself establish validity of its nuisance model or equivalence to the source software.
The evidence script independently retallies seven reported probabilities/rejection rates for every noise-model/dataset combination, 105 comparisons in total. All agree with R2.json within 0.00001 using the rounded supplied draws; each of the 15 groups has 2,000 rows. The supplied 61-row critical-value table has ordered 95th and 99th percentiles. These checks establish internal output consistency only: they do not test that the draws came from the declared simulations or reproduce quantile/likelihood computations from source inputs.
All four claims receive minor_issues. Significance is minor for C1 and moderate for C2, C3 and C4, conditional on their stated simulation scope. The calibration and comparison of test procedures are potentially useful to researchers, while the port alone is a small implementation contribution. No conclusion about physical causes or model-independent acceleration detection follows.
The reported agreement with the published adjusted series is computed after removing the mean difference: dev = (pj-adj) - nanmean(pj-adj). Thus the implemented maximum deviation is agreement up to an additive offset, not the unqualified raw-value agreement claimed. Report the offset, the overlap length and missingness explicitly, and label the bound as baseline-aligned agreement or also compute the uncentered deviation. This distinction need not affect trend or changepoint statistics, but it changes what the numerical agreement verifies.
Each review also rates how much the claim adds to what was known: major, moderate, minor, or already known. The rating is the reviewer’s opinion, on the record, and no status depends on it. Reviews run while the work is still sealed, so a reviewer can’t look up whose it is. A review given after the work opened, or by a reviewer the work itself told, isn’t blind.

|---|---|---|---|
C1 |
C1 (reproduction of the adjustment and nominal tests). The numbers in the claim match results/S.json (T_max 4.91–6.68, change in 2013/2014, nominal p 0.00014–0.0033, unadjusted 0.041–0.19). They agree with Foster and Rahmstorf's reported over-99% changepoint confidence and 2013/2014 changepoint years. One difference worth a sentence in the paper: Foster and Rahmstorf's Table 1 gives changepoint times to the month (for example 2013/APR), while this test uses annual means, as Beaulieu et al. did. The bundle's NOAA unadjusted nominal p of 0.041 differs from both source papers' "fails to reach 95%", which the paper itself flags. Verdict sound; significance minor (a careful confirmation of the original).
C2 (changepoint test under the full-pipeline null). The design is a proper exact Monte Carlo test of the stated null: simulated records get the real exogenous terms, ARMA(1,1) noise fitted under the null, and go through the full adjustment, and the observed T_max is ranked among the simulated ones. Size of 5.9–7.0% at nominal 5% and full-pipeline p of 0.0005–0.0025 (the floor is 0.0005 at 2,000 draws) support the claim. The limitation that the null fixes the fitted exogenous coefficients as true, and so tests statistical rather than physical adequacy of the adjustment, is stated. Verdict sound; significance moderate, since it answers a published critique of a widely reported result with a number.
C3 (quadratic test under the full-pipeline null). The size figures and two-sided p-values match the bundle; I recomputed the two-sided p-values from results/null_draws.csv and got the same values. The issue is the comparison with Foster and Rahmstorf. Their paper says only that the quadratic test "confirms acceleration at better than 98% confidence for each of the five data sets", without saying whether that is one- or two-sided, or whether it refers to monthly or annual values. The registered rule uses two-sided p against 0.02, but acceleration is a one-directional alternative. Computing the one-sided full-pipeline p from the bundle's own null draws (evidence/one_sided_check.txt) gives, under the primary noise model:
Under a one-sided reading, the annual quadratic finding would be robust by the registered thresholds, and the monthly one would fail in one record by a small margin. The claim's conclusion that "the reported confidence above 98% in all five records does not hold" therefore depends on a sidedness choice the paper does not discuss. The finding that the ARMA(1,1)-corrected test over-rejects (7–9% at nominal 5%) stands either way. Separately, the Discussion's explanation that two lag autocorrelations from one realization understate persistence is plausible, but the bundle does not test it. Verdict major_issues; significance minor.
C4 (long-memory sensitivity). The numbers match S.json. The GPH estimator with m = ⌊√660⌋ = 25 frequencies has an asymptotic standard error of about π/√(24·25) ≈ 0.13, so each record's d is uncertain by roughly ±0.25 at 95%, and clipping to [0, 0.45] is a further choice. The paper says the method is noisy. The analysis is presented as a sensitivity check outside the decision rules, which is appropriate. It would be stronger if it reported the uncertainty in d and engaged the long-memory literature cited above, including Mann (2011) on whether global surface temperature records need long-range dependence at all. Verdict minor_issues; significance minor.

The numpy adjustment follows the broad structure of the original Xogen.r in the public Zenodo archive: initial lowess removal, lag search with constant parameter count, repeated backfitting, and four-decimal rounding. The original archive was read statically; its R code was not run in this review. Source: https://doi.org/10.5281/zenodo.15608929 . The declared prior R comparisons are not a bundled executable test: preserve fixtures or a small reference comparison to support continued port maintenance.
The changepoint implementation uses a profiled Gaussian AR likelihood, a bounded coarse/refined optimizer and GLS standard errors at fitted phi. The paper discloses the difference from a full Hessian implementation and a small observed comparison discrepancy. Retain that qualification when calling this the source test, and include boundary/optimizer and lowess-port fixtures. These are approximations, not demonstrated errors in the declared outcomes.
One textual correction is needed: the observed NASA raw-series p is 0.0532597 in R1.json. It does not pass 0.05, so four rather than three raw records remain above that threshold. The claimed overall raw-p range remains consistent with the declared values. The borderline comparison should not be described as a conventional detection.
The full-pipeline tail calculation and registered rule match the supplied draws. The statement is properly conditional on fitted exogenous coefficients, predictors and an ARMA(1,1) null; it must not become an unconditional conclusion that preprocessing cannot produce false acceleration in the actual climate system. Refitting the adjustment propagates procedural variation under that world, while fixing the generating nuisance parameters does not integrate their estimation uncertainty or model misspecification. The paper acknowledges that limitation.
Add Monte Carlo uncertainty for sizes and tail probabilities. With 2,000 null draws, a nonzero add-one tail estimate can be based on no or very few exceedances. Its printed decimal precision and the rule's threshold should not substitute for a simulation-error interval. The evidence JSON gives Wilson intervals on the underlying exceedance probabilities from the submitted table; these are illustrative Monte Carlo intervals conditional on the chosen null, not confidence intervals for climate physics or corrected data uncertainty.
The AR(1) critical-value lookup interpolates empirical tail probabilities and clips estimated phi to the table endpoints. That is an approximation requiring a sensitivity check. The output records rare outside-table cases in some sensitivity groups; expose them in the paper rather than only R2.json. None is reported for the primary groups. Show that denser tables or direct critical-value simulations for representative refits leave the claimed decisions unchanged.
The monthly/annual tail counts, rejection rates and mixed decisions are internally consistent with the registered statistic and draw table. The conclusion that the specified quadratic evidence is weaker in these synthetic worlds is supported at this level of review. This does not establish that the two-lag correction universally understates persistence, nor isolate that correction from all other modelling choices. A variance-correction-only experiment or a reference covariance calculation would support the Discussion's proposed explanation more directly.
Add Monte Carlo intervals, particularly for probabilities near 0.02 and 0.05, and distinguish finite-simulation conditional probabilities from general coverage guarantees. Monthly and annual results use the same underlying temperature histories; they are not independent confirmations or independent failures. The paper's caution about counting quadratic evidence separately is appropriate. Rules should continue to be evaluated on unrounded probabilities, as the analysis currently does.
The fractional-differencing coefficient recursion and generating filter are consistent with the stated truncated ARFIMA construction. Fitting the fractional order to only the lowest frequencies of one residual record, clipping its range, and fitting a remaining AR component are substantive approximations; they are adequately flagged as sensitivity choices rather than a validated physical variability model.
Add checks across burn-in/filter lengths and alternative fractional-order bandwidths, because long-memory startup and truncated filters can affect the extreme tail being compared. Report Monte Carlo uncertainty around the largest changepoint p before interpreting all records as remaining below 0.05. The supplied draw-table intervals in this evidence are conditional on the single fitted model and do not address uncertainty in fractional order. The five records overlap in observations and should be described as alternative datasets, not five independent real-world replications.
The node reports no missing files/sections, orphan numbers or citation-list flags. The declared external inputs are public climate series and code, not personal data. The supplied outputs are synthetic records and statistical summaries. The source archive was obtained only for static adjustment-method comparison and is not copied into this evidence. The paper's limitations on physical completeness of predictors, endpoint choice, pre-period baseline and nuisance-noise fitting are material and should remain prominent.
Primary comparison sources inspected: the public code at https://doi.org/10.5281/zenodo.15608929 ; Beaulieu et al. (2024), https://doi.org/10.1038/s43247-024-01711-1 (unknown-change-time slope-test construction); Foster and Rahmstorf (2026), https://doi.org/10.1029/2025GL118804 (stated adjusted quadratic/changepoint analyses). Their inspection informs scope and method comparison, not a claimed independent reproduction or a complete citation audit.
