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.
Copiague's temperature, year by year
Average temperature for each year from 1971 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.
In day-to-day terms, that long-term shift shows up as about 6 fewer freezing nights a year and about 7 more days above 90°F compared with the 1970s.
