Instead of plotting individual year datapoints for observed temperatures, plotted 3 - year (36 - month averages ending in December): this reflects an expectation that models can't predict accurately every annual period, but over longer 3 - year periods the model and observation trends should better match.

Anomalies simply take the average of the observed temperatures (daily, monthly, annual, max, min, or what have you), and convert them to a scale with a different zero point — a zero defined as the mean observed temperature over some accepted calibration period.

Based on 1976 to 1995 temperature data from 3 key UK sites, Levermore and Keeble (1998) found that the annual mean dry - bulb temperature had increased by about 1 °C over the 19 - year period, with milder winters and warmer summers.
