Climate-smart agriculture: Food security in a warmer and more extreme world

  1. 1.               Climate-­‐smart  agriculture:   Food  security  in  a  warmer  and  more   extreme  world   Supported  by   Led  by   Strategic  partner  
  2. 2. 1.  Warmer and more extreme? 2.  Rising to the challenges? 3.  Linking knowledge and action?
  3. 3. Global  surface   temperature   change  (oC)   Why  the   bother  about   warming?   1       0.8       0.6       0.4       0.2   2003        2006        2009        2012  
  4. 4. Global  surface  temperature  change  (oC)   How  “SkepJcs”  View  Global  Warming

  8. 8. Young scientists may retire before global climate models are good enough for agriculture “Substantial increases in the reliability of projections from General Circulation Models (GCMs) are not expected any time soon” Richard Washington, University of Oxford GCM errors were often larger than 2 °C for temperature and 20 % for precipitation
