a warmer-than-average year a cooler-than-average year

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 7 fewer freezing nights a year and about 12 more days above 90°F compared with the 1970s.

When in the year the change shows up
