Has the climate in Potosí changed?

Potosí has cooled about 0.9°F between 1994 and 2018.

About 0.4°F per decade, measured from Potosí's official daily weather records, 1994–2018. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Potosí's climate has warmed more slowly than most other cities across South America.

What has actually changed

Each card compares the 1970s (the first ten years of the record) with recent years (the last ten) — the same span the headline and the chart use.

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.

Methodology & sources

Temperature — 1991–2020 normals computed from 28 years of daily observations at Capitan Nicolas Rojas, a weather station, about 5 km from the city centre. The underlying daily records come from NOAA's global station network.
