“The negotiations in Warsaw represent an important step in the negotiation process towards a climate agreement by 2015,” lead author Elmar Kriegler from PIK says. “While there are legitimate doubts about whether the Durban Platform negotiations can deliver on their promise, our analysis shows the importance of meaningful reductions in global emissions by 2020 to keep the 2 degree target within reach.” The later emissions get cut, the greater the necessary reduction rates to avoid more than 2 degrees warming, and hence the greater the impact on energy prices and economic growth.
“Even a delay of just 10 years of a climate agreement coming into effect would raise the economic challenges substantially, if emissions reduction efforts remained at their currently moderate level,” Kriegler says. The results are part of the comprehensive LIMITS project (Low Climate lmpact Scenarios and the lmplications of Required Tight Emission Control Strategies) on the implementation of 2 degree strategies in the major economies and will be published in a special issue of the journal Climate Change Economics. The scientists investigated a set of different outcomes of the Durban Platform negotiations process and their implications for reaching the 2 degree target with seven integrated assessment and energy-economy models to ensure the robustness of results....
