Has the climate in Oldenburg changed?

How Oldenburg's climate has changed

About 0.2°F per decade, measured from Oldenburg's official daily weather records, 1990–2011. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Oldenburg's climate has warmed more slowly than most other cities in Germany.

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.

In day-to-day terms, that long-term shift shows up as about 8 more freezing nights a year compared with the 1970s.

When in the year the change shows up

How much warmer each month is now than in the 1970s. Useful if you garden or care about a particular season — otherwise the headline above already has the answer.
