How Global Mean Temperature Change Is Measured and Reported
Captions available
The idea
Temperature change is reported as an anomaly, the difference from a fixed baseline.
In practice
A given anomaly means that year's average differed from baseline by that amount, not that every location changed equally.
Where people slip
Assuming satellites and stations measure temperature identically is the error — the methods differ, then reconcile into one series.
