2019 year-to-date temperatures versus previous years

Global Year to Date Temperature Anomalies

This graphic compares the year-to-date temperature anomalies for 2019 (black dot) to what were ultimately the ten warmest years on record: 2016, 2015, 2017, 2018, 2014, 2010, 2013, 2005, 1998, and 2009. 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–May 2019 was 0.93°C (1.67°F) above the 20^th century average of 13.1°C (55.5°F)—the third highest global land and ocean temperature for January–May in the 1880–2019 record, behind 2016 (+1.14°C / +2.05°F) and 2017 (+0.97°C / +1.75°F).

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