Summary

Svalbard surface temperature mean monthly anomalies 1912 to 2006, in °C. Anomalies are station monthly mean temperatures minus the local full-record average for the month.

The recording station moved some 47 km from Isfjord Radio (78.1 N 13.6 E) to Svalbard Luft (78.2 N 15.5 E) in 1976, with little record overlap. There is an obvious large station temperature difference. To produce a combined anomaly record, the station difference is here adjusted by subtracting 1°C from Isfjord and adding 2°C to Luft, so that the trend lines meet at the station change. The resulting zero crossing is near 1975, so the anomalies relate approximately to the usual 1960-90 interval.

The Svalbard record shows one of the strongest long-record warming trends on earth, in close agreement with model predictions.
