Has the climate in Jwaneng changed?
Jwaneng has cooled about 1.1°F between 1995 and 2022.
About 0.6°F per decade, measured from Jwaneng's official daily weather records, 1995–2022. 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.
Jwaneng's temperature, year by year
Average temperature for each year from 1995 to 2022.
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.
