For computer simulation models to usefully inform climate risk management, uncertainties in model projections must be explored and characterized. Because doing so requires running the model many ti...

Mission-oriented climate change research is often unverifiable. Therefore, many stakeholders look to peer-reviewed climate change research for trustworthy information about deeply uncertain and impactful phenomena. This is because peer-review signals that research has been vetted for scientific standards like reproducibility and replicability. Here we evaluate the transparency of research methodologies in mission-oriented computational climate research. We find that only five percent of our sample meets the minimal standard of fully open data and code required for reproducibility and replicability. The widespread (...) lack of minimal openness standards in peer-reviewed climate change research jeopardizes scientific credibility and risks poor societal outcomes as we manage growing climate risks. The scientific community can and must do better. We, the authors, outline necessary openness standards that we commit to as researchers, reviewers, and readers. We invite you to join us. (shrink)

Accelerating global climate change drives new climate risks. People around the world are researching, designing, and implementing strategies to manage these risks. Identifying and implementing sound climate risk management strategies poses nontrivial challenges including (a) linking the required disciplines, (b) identifying relevant values and objectives, (c) identifying and quantifying important uncertainties, (d) resolving interactions between decision levers and the system dynamics, (e) quantifying the trade-offs between diverse values under deep and dynamic uncertainties, (f) communicating to inform decisions, and (g) learning (...) from the decision-making needs to inform research design. Here we review these challenges and avenues to overcome them. ▪ People and institutions are confronted with emerging and dynamic climate risks. ▪ Stakeholder values are central to defining the decision problem. ▪ Mission-oriented basic research helps to improve the design of climate risk management strategies.
