Segmented regression with data from DWD station Potsdam from 1893 to 2024. It shows a breakpoint at 1987 and a trend of 0.0047/a before 1987 and a trend of 0.057/a since then.

Here a local example from a long-term station (Potsdam, close to Berlin) with data from the German Weather Service (DWD) since 1893. I created the example for a course with R packages #strucchange and #segmented. The years 2023 and especially 2024 are clearly above the trend line.
