2018 year-to-date temperatures versus previous years


2018 year-to-date anomalies through February compared to nine 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 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–February 2018 was 0.68°C (1.22°F) above the 20th century average of 12.1°C (53.8°F)—the eighth highest global land and ocean temperature for January–February in the 1880–2018 record. This value is also 0.46°C (0.83°F) cooler than the record set in 2016.

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