Key Question for Today Key Question for Today Key Question for Today What are the energy technology implications of stabilizing climate—not just CO 2 concentrations? � Interactions with uncertainty in biogeochemical parameterization; � Interactions with uncertainty in technology developments. Inspired by the work of Richels, Manne and Wigley. 4
