first forecast hour, model simulations tend towards the values at the end of the previous run, but
especially in the interior of the island, some significant differences remain.

For 2-m air temperature and 10-m wind speed, this is illustrated in Figure 5, based on average
diurnal cycles, calculated separately for grid points

The final conference of the CES project "Future Climate and Renewable Energy - Impacts, Risks and Adaptation" was held in Oslo from 31 May to 2 June. The conference was organised around five themes:
Past and present changes in climate

that; (1) ambiguity exists in defining operational targets for the different
management goals to be achieved, (2) conflicts of interests require participatory goal setting
and a clear recognition of uncertainties in this process, and finally (3) the system to be
managed is subject to change due to environmental and socio-economic developments,
calling for a flexible adaptation of the management

and Jylhä, 2007) and extreme precipitations are expected to in-
crease (Beniston et al., 2007). On the other hand, temperature in-
creases of 2–6 C by the end of the century are estimated to
decrease the snow accumulation by 40–70% by the same period

Group 1 – Scenarios
Objective
To build scenarios for use in a 20 years planning process aiming at design of a climate change
adaptation plan.
Tasks – questions to be answered
1. Knowledge gathering – climate change effects
o Which knowledge is needed regarding climate effects and the involved uncertainties? What

The Wind Energy group
http://www.os.is/ces
Focus in the CES project is on conditions for production of electricity from wind energy in the Nordic
area and how they might change due to global warming during the next decades. This relates both to
the production potential and especially design conditions for wind farms and their sensitivity to
