pared with similar beginning and end years. Consequently, for the 2004–50 period, the average
RCM warming rates of 0.29 K per decade over the ocean, and 0.35 K per decade over the land are
somewhat larger than for the reduced IPCC ensemble mean.
Additionally, the tabulated values of SAT differences between the 1961–90 control period and

This is also the case with
cyclones in all three sectors. Cyclones in the eastern or western sector are also strongly affected
by the presence of central cyclones. In both sectors, cyclones tend to move east, unless there are
cyclones in the neighbouring sector, in which case pressure tendencies are reversed.

Future improvements should be made in the light of applications within a larger toolbox of scenario

samples of citizens in its Member States, and specifically on topics related to the
environment (Special Eurobarometers (EB) in 1992, 1995, 2002; and a Flash EB
in 2002). These have included
