The use of scenarios as the basis for combined assessment of climate change mitigation and adaptation. Global Environmental Change 21: 575-591.
This paper summarizes the results of several analyses that investigate the global impacts on various determinants of human well-being, including malaria, agricultural productivity, water stress, sea level rise, and heating and cooling demand through 2100 under a “no climate change” scenario and two “policy” scenarios. The first policy scenario, which serves as the “baseline,” assumes no climate change policies and would increase the global mean temperature by 4 °C above the pre-industrial level by 2100. The second is a Mitigation scenario which would stabilize greenhouse gas concentrations at around 450 ppm CO2-equivalent leading to a 2 °C increase in 2100. Its aim is to assess the effects of an aggressive mitigation policy on the global impacts of climate change. (more…)
