Explanation
A temperature anomaly measures how much warmer or cooler a year is compared with a reference period. Scientists use anomalies because they make long-term climate change easier to compare across regions and time. NASA GISTEMP combines many observations into a global temperature record. Short-term variability still happens from year to year, but the long-term pattern is clear: recent decades are much warmer than the early record.
