Climate scientists typically describe global warming in terms of anomalies; that is, temperatures above and below the average global temperature. The average they are comparing it to is the 30 year period between 1961 and 1990 when the earth’s average temperature was around 57.2 and did not change in general for that period of time. The changing of the temperature after 30 years of being constant is what is considered an anomaly and thus climate scientists generally use the last average global temperature to compare with today’s temperatures.
