Info

AR4 spatial pattern that suggests more severe drying of up to 20% in the south, and less drying in the north (between 5 and 10% reductions). This suggests that rainfall impacts as modelled by Midgley et al. (2005) may tend towards the conservative in the south, and be less conservative for the north-west and northern coastal regions. Temperature increases modelled by Midgley et al. (2005) agree well with those projected by the IPCC AR4 for 2100, of around 4°C. One key feature of Namibia’s climate is the coastal fog system, which is known to be key for several elements of biodiversity, but there are unfortunately currently no credible projections of change for this system. 96 USAID/NAMIBIA ENVIRONMENTAL THREATS AND OPPORTUNITIES ASSESSMENT
