Adaptation and Mitigation Ways to Address Climate Change
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
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
A clever colleague once said "Mitigation helps us avoid the unmanageable, while adaptation helps us manage the unavoidable."
Mitigation Adaptation
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/
