text: Four countries show ensemble-mean HCVI values at 2°C global warming that are higher 
  than any seen in the baseline climate; these are Oman, Bangladesh, Mauritania and Yemen. 
  The implication of such HCVI values is that climate change at 2°C is projected to cause levels 
  of vulnerability to food insecurity that are greater than any seen in the present day. For 
  individual ensemble members, the number of countries with ‘unprecedented’ HCVI values at 
  2°C varies from three to seven. Conversely, many countries in the baseline climate have levels 
  of vulnerability to food insecurity that are greater than those expected in other countries under 
  2°C global warming. This suggests that other factors are already posing greater risk for food 
  insecurity than 2°C climate change is expected to cause in other countries, so the increased risk 
  from climate change should not overshadow the need to reduce vulnerability to food insecurity 
  arising from non-climatic factors. There is scope to reduce vulnerability to food insecurity by 
  addressing various socio-economic issues in such counties. 
  
  increased run-off over 
  approximately half of the land surface (ﬁgure 9) and the majority of the major river basins 
  assessed (ﬁgure 10), but with large regional uncertainties including the possibility of decreased 
  ﬂows in many basins. The ensemble-mean change in mean streamﬂow shows an increase of 
  between 5 and 25% over most of the Northern Hemisphere land surface, with some regions seeing 
  an increase of over 50% at 2°C global warming. Notable exceptions to this are western Europe and 
  southcentral USA, which see less than a 5% change in run-off, and the already very dry region of 
  the Sahara Desert where the existing very small run-off become even smaller.
