Assessment of Red Sea temperatures in CMIP5 models for present and future climate

By the end of the century (2080–2100), the averaged surface temperature would increase with respect to present conditions 1.6˚C±0.4˚C˚C and 3.3˚C±0.7˚C (ensemble mean ±> spread) under scenarios RCP4.5 and RCP8.5, respectively (Fig 9). Temperature vertical profiles All GCMs that have been evaluated project a rather uniform warming across the basin at dif- ferent depths. Under scenario RCP8.5 they project more intense warming in the upper layers, with anomalies in the period 2080–2100 above 3˚C with respect to present values, while decreasing to 2.2˚C at 300 m (S4 Fig). This difference in the rate of warming between the two Fig 8. Projected SST (in ˚C) for the period 2080–2100 under RCP 8.5 scenario (top), and RCP 4.5 scenario (bottom).
