I would like to indicate that the global warming does not evenly distributed across the entire world. There is much more spatial variability due to some local variables such as teleconnections and atmospheric circulation. For instance, the behaviour of maximum temperature along the Mediterranean shows different evolution between the North (increasing) and the South (decreasing) of the Mediterranean basin. For instance, the behaviour of the annual maximum trend in Libya (an average of -0.06 °c decade-1) comes in general agreement with areas located in the same latitudes ( – 0.22 °c decade-1 ) in Egypt . However, this behaviour contrasts to the observations in the north and east of the Mediterranean basin, e.g. Italy (Brunetti et al. 2000 and 2006), the Iberian Peninsula (Brunet et al., 2005), Greece (Philandras et al. 2008) and the Balkans (Gajic-Capka and Zaninovic, 1997; Unkašević et al., 2005).
