Has the climate in Palmas changed?

How Palmas's climate has changed

About 0.1°F per decade, measured from Palmas's official daily weather records, 2008–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

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

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.
