Decision support tools and decision-analytic methods are available and are being applied for managing climate risks in varied contexts, including where deep uncertainty is present . These tools and methods have been shown to support deliberative processes where stakeholders jointly consider factors such as the rate and magnitude of change and their uncertainties, associated impacts and timescales of adaptation needed along multiple pathways and scenarios of future risks . However, comparative evidence on the relative utility of different analytical methods in their use by decision makers for managing climate risks is an important gap . Nevertheless, robust decision-making, using pathway analyses to determine 'no regrets' options among trade-offs, has been shown to be a useful starting point under deep uncertainty . Methods for analysing options differ across geo- political scales, with modelling studies being a particularly prominent method across scales from community and urban to regional and national  .
