Presentation Transcript

  1. Adaptation and Mitigation Ways to Address Climate Change

  2. What is Mitigation? • To prevent the worsening of destruction • To decrease force or intensity. To lower risk. • Earthquake mitigation • Build buildings to withstand shaking better • Flood mitigation • Build dams to hold back overflowing rivers • Climate change mitigation • Reduce carbon dioxide emissions

  3. What is Adaptation? • Reacting or changing to fit the new circumstance • Coping with impacts that cannot be avoided Examples: • farmers planting different crops for different seasons • wildlife migrating to more suitable habitats as the seasons change. • Building levees against sea level rise

  4. A clever colleague once said "Mitigation helps us avoid the unmanageable, while adaptation helps us manage the unavoidable."  

  5. Mitigation Adaptation

  6. Halting emissions growth is not enough Change in world temperatures World C emissions Continued growth and flat emissions scenario are taken from the IIASA GGI database (A2r and B2, respectively). Stabilization case is adapted from the B2 480 ppm scenario. http://www.iiasa.ac.at/web-apps/ggi/GgiDb/
