Has the climate in Foligno changed?

Foligno has warmed about 2.6°F between 1991 and 2024.

About 0.8°F per decade, measured from Foligno's official daily weather records, 1991–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Foligno's warming is broadly in line with other cities in Italy — neither unusually fast nor unusually slow.

Each bar is one year. Most recent years sit above the older ones. Some recent years still came in cool — warming is a slope, not a straight climb.
