The last two months of the year were warm. Wind speed was close to
average.

favourable, but less settled than during the previous three
years. The temperature was above the 1961-1990 normal, about 0.7 to 0.9°C in most areas,
but 0.3 to 0.6°C in the Southeast. The highest temperature of the year was measured at Burfell
in the southern inland on 23 July, 25.9°C and the lowest at Kolka in the central highlands on 2

The precipitation was below normal

Noises: Scientists working at Gígjökull regularly hear explosions and booming
sounds and feel the ground vibrate. The vibrations are not felt in 3-4
km distance.
Additional note: The scientists at Gígjökull experienced discomfort due to gas.
Meltwater: Today water temperature at the Markarfljot bridge was measured 11°C
but about 3°C in a 2 km distance from Gígjökull. Water

(Hansen et al., 1983, 1984). Differences between the 1 CO2 and 2 CO2 equilibrium experiments
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

the mountain, in
particular the settlement near Stöðvarlækur and Búðará, may also be threatened by fast-
moving debris flows from high elevations in Strandartindur that can be affected by
permafrost. There is high hazard, corresponding to the C-zone in the Icelandic hazard
zoning regulation, within the main debris flow paths below Þófi and the eastern part of
Botnabrún to Nautaklauf
