Method and limits

  • Data: annual means from NOAA (GHCN) and ECA&D stations. A station is ranked when it has at least 20 years in 1961–1990 and 8 years in 2016–2025.
  • One row per station: when several towns share the same station, only the nearest one is shown.
  • These are raw, non-homogenised series: a station move, an instrument change or urban growth can increase or reduce the change at one station. The country median is more robust than the rank of any single city.
  • Changes below −1.5°C or above +6°C are treated as measurement breaks and left out.
