Has the climate in Adamstown changed?

Adamstown has warmed about 0.9°F between 1972 and 2002.

About 0.3°F per decade, measured from Adamstown's official daily weather records, 1972–2002. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Adamstown's warming is broadly in line with other cities across Oceania — 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.
