CONUS Temperature Horserace

This graphic compares the year-to-date temperature anomalies for 2015 (black line) to what were ultimately the ten warmest years on record for the contiguous United States (CONUS). Each month along each trace represents the year-to-date average temperature — a cumulative value for the year. In other words, the January value is the January average temperature, the February value is the average of both January and February, and so on.

The anomalies themselves represent departures from the 20th century average temperature. The graph zooms into the warmest part of the entire history. For a broader perspective on how these years relate to the long-term record, click here.
