Scientific synthesis: fitness for purpose of current IAM approaches

Scientific synthesis: fitness for purpose of current IAM approaches (including inter-model comparison from users’ perspectives):This deliverable is the publicly disseminated output of Task 4.1, reporting findings of questionnaire- and interview-based ‘market research’ on IAM users, with particular focus on target users in governance contexts beyond national climate policy-making (exploring what they use IAMs for and why, clarifying issues such as trust, confidence and uncertainties in relation to model scope / boundaries). To better understand the suitability, strengths and limitations of current IAM approaches in satisfying the information needs and requests of their users, this deliverable also consists of a structured appraisal of current approaches, including selected case studies relevant to the human world / biophysical Earth IAM developments in WP1 and WP2. This deliverable informs Task 4.4 and the workshops convened in WP5, and is relevant to D3.3’s reporting of simple IAMs and their uncertainties.
