Has the climate in Macapá changed?

About 0.5°F per decade, measured from Macapá's official daily weather records, 1973–2020. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Macapá's climate has warmed faster than most other cities in Brazil.
