Has the climate in Giresun changed?
Giresun has warmed about 3.7°F since 2002.
About 1.5°F per decade, measured from Giresun's official daily weather records, 2002–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
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.
Giresun's temperature, year by year
Average temperature for each year from 2002 to 2025.
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.
Methodology & sources
Temperature — 1991–2020 normals computed from 14 years of daily observations at Giresun, a weather station, inside the city. The underlying daily records come from NOAA's global station network.
