Annual 2024 Global Climate Report

2024 year-to-date temperatures versus previous years


The ten warmest years on record
Global Year to Date Temperature Anomalies

This graphic depicts the ten warmest years on record (1850-2024): 2024, 2023, 2016, 2020, 2019, 2017, 2015, 2022, 2021, and 2018. 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 Januaryโ€“December 2024 was 1.29ยฐC (2.32ยฐF) above the 20th century average of 13.9ยฐC (57.0ยฐF)โ€”the highest global land and ocean temperature for Januaryโ€“December in the 1850โ€“2024 record.

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