2018 year-to-date temperatures versus previous years


2018 year-to-date anomalies through December compared to eight warmest years on record
Global Year to Date Temperature Anomalies

This graphic compares the year-to-date temperature anomalies for 2018 (black line) to what were ultimately the other nine warmest years on record: 2016, 2015, 2017, 2014, 2010, 2013, 2005, 2009, and 1998. Each month along each trace represents the year-to-date average temperature anomaly. In other words, the January value is the January average temperature anomaly, the February value is the average anomaly of both January and February, and so on.

The average global land and ocean surface temperature for January–December2018 was 0.79°C (1.42°F) above the 20th century average of 13.9°C (57.0°F)—the fourth highest global land and ocean temperature for January–December in the 1880–2018 record, behind 2016 (warmest), and 2015 (second warmest), and 2017 (third warmest).

The anomalies themselves represent departures from the 20th century average temperature. The graph zooms into the warmest part of the entire history.
