  1. A comparison of these quantities is made between the observational dataset MEDATLAS-II (MEDAR-Group 2002) for the period 1945–2002 and both historical simulations, HIS and HIS-F, for the period 1961–1990. The difference between modelled quantities in scenario simulations (2070–2099) and the respective historical simulation (1961–1990) is displayed. The statistical significance is estimated using a t test, “n.s.” means that the value is not significant
