- A world of independently operating, self-reliant nations.
- Continuously increasing population.
- Regionally oriented economic development.

This projection is included (nr. 8 in Table 1) in the investigation by Kjellström et al. (2011). There, average temperature and precipitation changes in Scandinavia (from 1961-1990 to 2011-2040, 2041-2070 and 2071-2100) in all 16 projections were compared (Fig. 10). Generally, the future increases in temperature and precipitation are linearly related, where a weak temperature increase corresponds to a weak precipitation increase, and vice versa. Below, “increase” corresponds to both temperature and precipitation; “small” means that the increase is among the smaller ones of all 16 projections considered, “medium” that the increase is among the middle ones, and “large” that the increase is among the larger ones, for the period considered.
As compared with all 16 projections considered, the increase in projection ECHAM5_A2_1 is:
