2022 Year-to-Date Temperatures Versus Previous Years

Global Year to Date Temperature Anomalies

This graphic compares the year-to-date temperature anomalies for 2022 (black line) to what were ultimately the ten warmest years on record: 2016 (1st), 2020 (2nd), 2019 (3rd), 2015 (4th), 2017 (5th), 2021 (6th), 2018 (7th), 2014 (8th), 2010 (9th), 2013 (10th), and 2005 (10th). 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–September 2022 was 0.86°C (1.55°F) above the 20th century average of 14.1°C (57.5°F), the sixth-warmest January–September period in the 143-year global record.

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