Challenges and opportunities toward improved data-guided handling of global climate model ensembles for regional climate change assessments

نویسنده

چکیده

Global climate models (GCMs) are important tools for addressing climate change questions at a global scale. Recent research has attempted to combine outputs from multiple GCMs to quantify uncertainty in regional climate change, which may ultimately inform regional stakeholders and policy-makers. Using a case study, we illustrate a potential path toward improvement in an existing Bayesian formulation, which may ultimately result in more physically meaningful GCM combination and hence add value to decision-making. This area of research is still nascent and may benefit from innovations in the computational data sciences.

Challenges in combining projections from multiple climate models

Recent coordinated efforts, in which numerous general circulation climate models have been run for a common set of experiments, have produced large datasets of projections of future climate for various scenarios. Those multimodel ensembles sample initial conditions, parameters, and structural uncertainties in the model design, and they have prompted a variety of approaches to quantifying uncert...
