of continuous observations in 1870. In Akureyri it was slightly
colder, the year being the 31st warmest since 1882. All months, except two, were above the
mean. The average temperature in Reykjavík was 5.6°C, 1.2°C above the 1961 to 1990
normal. In Akureyri the average was 4.1°C, 0.8°C above normal. In Stykkishólmur in the
West the average was 4.7°C, 1.2°C above the normal.

were used to estimate greenhouse effects. Interpolated to Stykkishólmur, the warming annually
was about 4 C, but ranging over the course of the year between 4.1–4.3 C from November to
April, and between 3.6–3.8 C from June to September. Thus the wintertime warming exceeded
