What NOAA's 2025 assessment establishes (claimIndex 0). NOAA ranks 2025 as the third-warmest year in its global temperature record, which dates back to 1850 . Its surface-temperature section states that 2025 ranked as the third-warmest year since global records began in 1850, with the annual global surface temperature 2.11°F (1.17°C) above the 20th-century average, behind 2024 (by 0.22°F/0.12°C) and 2023 (by 0.04°F/0.02°C) . NOAA also reports that the 10 warmest years in the historical record have all occurred since 2015 . Separately, NOAA reports record-high upper ocean heat content in 2025 .
Baseline (claimIndex 1). The baseline NOAA uses for its 2025 global surface temperature anomaly is the 20th-century average . The supplied NOAA passages do not state a pre-industrial baseline; the 1850–1900 pre-industrial baseline appears only in the Berkeley Earth source, not in the NOAA excerpts .
Uncertainty (claimIndex 2). The supplied NOAA passages do not report an uncertainty range for the 2025 global temperature assessment, so this part of the question is unanswered by the NOAA material provided. The only uncertainty figure in the supplied sources is Berkeley Earth's, which is not NOAA: Berkeley Earth estimates 2025 at 1.44 ± 0.09 °C above the 1850–1900 average and states that its single-year uncertainty for recent years is approximately 0.03 °C (0.05 °F) . Berkeley Earth also notes that, due to reporting delays, NOAA and NASA averages for 2025 are based on 11 months of data .
Limits on attributing one local flood to global climate trends (claimIndex 3). The supplied passages from either source contain no statement by NOAA (or Berkeley Earth) about the limits of attributing a single local flood to global climate trends. This part of the question is therefore unanswered by the provided sources. The NOAA excerpt does reference a "Map of global notable weather and climate events in 2025" , but the passage does not discuss attribution limits, so it cannot support an answer here.
Observation vs. inference. Observations reported by NOAA: 2025 ranked third-warmest since 1850; the annual global surface temperature was 2.11°F (1.17°C) above the 20th-century average; the 10 warmest years have all occurred since 2015; upper ocean heat content was record high . Inference drawn from these observations (e.g., that the run of recent warm years reflects an ongoing warming trend, or that any particular flood is linked to global climate trends) is not stated in the supplied passages and should not be attributed to them.

NOAA NCEI's own 2025 annual global climate summary — the exact original source the question demands. Preview already shows NOAA ranks 2025 as third-warmest in a record dating to 1850, directly supporting claimIndex 0 (what the assessment establishes) and touching the baseline/record-length context for claimIndex 1. Free public read, no toll. - free public original-page READ selection (not a cache hit); no purchase or creator reward. — selected for the claim-aware evidence portfolio (targets claims 1, 2; 0 fetch USDC, 1 attention slot).
Berkeley Earth's 2025 report gives an explicit uncertainty figure (1.44 ± 0.09 °C vs 1850-1900) and a baseline, which is a strong independent comparator for claimIndex 2 (uncertainty) and claimIndex 1 (baseline). Not a NOAA source, so it cannot substitute for the NOAA assessment, but it is free and directly on-topic. - free public original-page READ selection (not a cache hit); no purchase or creator reward. — selected for the claim-aware evidence portfolio (targets claims 2, 3; 0 fetch USDC, 1 attention slot).
NOAA Climate.gov explainer that spells out NOAA's baselines (20th-century average and pre-industrial average) and per-decade warming rates — useful for claimIndex 1 (baseline definition) and background for claimIndex 0. It is NOAA-authored but previewed content is the 2024 report, so it is supporting context rather than the 2025 result itself. - free public original-page READ selection (not a cache hit); no purchase or creator reward. — the claim-aware portfolio chose a stronger, less redundant set inside the 2-source attention and $0.025000 fetch-budget caps, so this proposal stays unspent.
Hansen et al. 2025 temperature paper states a baseline (1880-1920) and a 2025 anomaly, useful cross-check for claimIndex 1 and for the observation-vs-inference separation the question asks for. It is a prediction-oriented non-NOAA analysis, so it is secondary to the NOAA originals. - free public original-page READ selection (not a cache hit); no purchase or creator reward. — the claim-aware portfolio chose a stronger, less redundant set inside the 2-source attention and $0.025000 fetch-budget caps, so this proposal stays unspent.
WMO State of the Global Climate 2025 corroborates the multi-year record framing (2015-2025 hottest 11 years) relevant to claimIndex 0, but it is not NOAA and the preview does not address baselines, uncertainty, or attribution limits. Free, so low-cost corroboration only. - free public original-page READ selection (not a cache hit); no purchase or creator reward. — the claim-aware portfolio chose a stronger, less redundant set inside the 2-source attention and $0.025000 fetch-budget caps, so this proposal stays unspent.
Mirror of the NOAA Climate.gov global-temperature explainer (Lindsey & Dahlman) covering warming rates and NOAA's baseline conventions — marginal support for claimIndex 1. Redundant with the climate.gov entry, so lower value. - free public original-page READ selection (not a cache hit); no purchase or creator reward. — the claim-aware portfolio chose a stronger, less redundant set inside the 2-source attention and $0.025000 fetch-budget caps, so this proposal stays unspent.
An @NOAA social post announcing the 2025 analysis. It only points to the findings; it carries no baseline, uncertainty, or attribution content, so it cannot advance any of claimIndex 0-3 beyond what the NCEI page already provides. - free public original-page READ selection (not a cache hit); no purchase or creator reward.
NOAA NCEI but for August 2026, a different reporting period than the 2025 annual assessment. Its seasonal figures do not establish the 2025 result, baseline, uncertainty, or attribution limits. - free public original-page READ selection (not a cache hit); no purchase or creator reward.

Final coverage assessment — The supplied NOAA excerpt (S1) directly establishes the 2025 global temperature result and baseline, but does not report a numerical uncertainty range for that assessment and does not discuss attribution limits for a local flood. S2 is Berkeley Earth, not NOAA, and therefore cannot fill NOAA-specific gaps, though it provides context on uncertainty and cross-agency differences. The assessment does not establish a complete supported answer for every requested part.

Relevance review returned; only checked excerpts can retain support, and review cannot raise it.
⚖️ Sources disagreed on Whether the 2025 global temperature assessment is NOAA's alone or corroborated by independent groups — S1 NOAA presents its own ranking of 2025 as third-warmest in its record dating to 1850, with a 20th-century-average baseline. vs S2 Berkeley Earth independently concludes 2025 was third warmest since 1850, using an 1850–1900 baseline, and notes most monitoring agencies concur though NASA and DCENT place it second warmest. → reported preference: S1 (The question asks specifically about NOAA's assessment; S1 is the NOAA original and is therefore the authoritative source for NOAA's ranking and baseline, while S2 is an independent analysis useful only as corroboration.)
