Temperature Anomaly vs Observed Temperature

What Is a Temperature Anomaly?

A temperature anomaly is the difference between an observed temperature and a long-term baseline average for the same location and time period.

Formula

Anomaly = Observed Temperature - Baseline Average

Anomalies are preferred over absolute temperatures for tracking climate change because they remove local biases and allow meaningful comparisons across different locations and elevations.

Example Calculation

The global mean temperature is observed at 15.2°C against a 20th-century baseline of 14.0°C.

  1. 01Anomaly = 15.2 - 14.0 = 1.2°C above baseline
  2. 02In Fahrenheit: 1.2 x 1.8 = 2.16°F above baseline
