“…An optimistic model ("Panel Climate Model" -PCM, Washington and al., 2000), a pessimistic model ("Canadian General Circulation Model" -CGCM, Boer and al., 2000) and an intermediate model ("Centre for Climate Research Studies Model"-CCRS, Emori and al., 1999). Focusing on the African and European continents, there emerges from these models a rise in temperature in 2100 ranging from 2.3° (PCM, Africa) to 6.2° (CGCM, Africa) compared to the preindustrial level.…”
