Summary

The last three years have reached record global temperatures. Changes to the climate are not typically visible in daily data because the shifts are too gradual. Warming is accelerating so fast that even through the noise of daily temperature data, it’s clear how abnormal the past few years have been. We are in uncharted territory.

This visualization keeps close tabs on daily global air surface temperatures. It is automatically updated daily.

The data

This visualization displays global (90°S-90°N, 0-360°E), deseasonalized surface air temperature (2-meter height) anomaly estimates from the ECMWF Reanalysis version 5 (ERA5). Anomalies are calculated by comparing each day's average global temperature to the pre-industrial baseline (1850-1900) using adjustment values provided by Copernicus C3S. This plot uses the pre-industrial baseline in order to highlight warming relative to global climate targets. The chart is updated daily with a lag time of 6 or 7 days from the current date due to ERA5’s availability via Copernicus C3S.
