and glaciers. The former trend is mainly visible in the
Westfjords, an area in northwest Iceland, in the winter (see Figure 8a and 8b) and in northeast
Iceland in the summer, especially east of Akureyri in the RCP8.5 scenario (see Figures 8c
and d). The latter trend is most clearly seen during summer and in cases with the RCM RCA4
with RCP8.5.

approximately centred around Iceland: the outer domain with
43 42 grid points spaced at 27 km (1134 1107 km), the intermediate domain with 9590 grid
points spaced at 9 km, and the inner domain with 196 148 grid points spaced at 3 km. The
northwest corner of the outer domain covers a part of the southeast coastal region of Greenland.
Otherwise, the only landmass included in the model domain

seimic network, fewer then the previous week when they counted around 620 in total. The most seismic activity was measured on the Tjörnes fracture zone with around 90 events located in the Eyjafjarðaráll north of Eyjafjörður, where the largest event of the week was detected, M4.2 on April 18th at 7:59 am. It was felt in the town of Siglufjörður. Quite more activity was detected in Vatnajökull

currents in its outer core. At the surface, about 90% of the field can be described by a simple dipole field tilting about 10° from the rotation axis. The currents in the Earth's core are slowly varying causing slow changes of the magnetic field, typically on timescales of years and ages.
A flow of charged particles from the sun, called the solar wind, hits steadily the magnetic field and bends

Simplest case: change in mean climate,
with no change in the magnitude of variability
If variability changes as well, the two tails of the distribution
(e.g., warm and cold) will be affected differently.
