The coupling of optimal economic growth and climate dynamics

摘要: In this paper, we study optimal economic growth programs coupled with climate change dynamics. The is based on models derived from MERGE, a well established integrated assessment model (IAM). We discuss first the introduction in MERGE of set “tolerable window” constraints which limit both temperature and rate change. These constraints, obtained ensemble simulations performed Bern 2.5-D model, allow us to identity domain intended preserve Atlantic thermohaline circulation. Next, report experiments where two-way coupling realized between module an intermediate complexity “3-D-” (C-GOLDSTEIN) computes changes mean temperature. achieved through implementation advanced “oracle optimization technique” permits integration information coming during search for path. Both cost-effectiveness cost-benefit analysis modes are explored combined “meta-model” refer as GOLDMERGE. Some perspectives future implementations these approaches context “collaborative” or “community” modules comparison different approaches.
