The same aggregates shown on the site, in a single downloadable file: no scraping needed.
One row per each of the 107 monitored cities: 1961–1990 climate normal, 1991–2020 normal, warming, per-decade trend (R²), and the series' start year.
slug, citta, regione, lat, lon — city identifiers (Italian names)normale_1961_1990, normale_1991_2020 — 30-year climate averages, °Criscaldamento_c — difference between the two normals, °Cgradi_decennio — linear-regression slope, °C/decadegradi_decennio_ic95 — ± margin of the 95% confidence interval on the sloper2 — goodness of fit of the line (0–1)anno_inizio_serie — first year with complete dataWarming = 1991–2020 normal minus 1961–1990 normal (the difference between two 30-year averages, not a recent year against the past). Trend = ordinary least squares regression on the annual means of the whole series, with a 95% confidence interval on the slope (standard error × Student's t critical value).
Snapshot generated on 2026-08-06, source Open-Meteo Archive API — ERA5 reanalysis (ECMWF/Copernicus C3S). Re-running the same method on this exact snapshot (the history.json file in the repository) reproduces exactly the same numbers. Integrity fingerprint (SHA-256 of the per-city aggregates): 70ba0eed343ef15e8ce4ca55d705d655e2ae1ddef12e34253ecb91a1b0769fb7.
The fingerprint above is anchored to the Bitcoin blockchain via OpenTimestamps: a proof — verifiable by anyone, without trusting us — that this exact dataset existed at a given date and hasn't changed since. We don't put the data on-chain, only its hash. Free, no coins.

Verify it yourself — download the proof and manifest, then:
pip install opentimestamps-client
ots verify -f stamp-2026-07-11-988097c9.txt stamp-2026-07-11-988097c9.otsThe manifest contains the same SHA-256, so verifying it proves that all the numbers already existed at that date. The proof starts calendar-attested and enters a Bitcoin block within hours. It anchors the snapshot committed to the repository (reproducible from git at that commit); the live data refreshes continuously, so the current fingerprint above may differ from an already-anchored one.
