Editorial statement
The paper advances hazard and risk science by developing a cross-hazard framework for systematically identifying, separating, quantifying, and communicating multiple sources of uncertainty, centred on the novel concept of a “complete forecast.” The paper can be a highlight paper because it bridges traditionally fragmented disciplinary approaches to uncertainty and offers a broadly applicable foundation for more transparent model evaluation, risk communication, and uncertainty-informed decision-making.
Short summary
Natural systems are complex and uncertain, making probabilistic forecasts essential. Representing and communicating all uncertainties is challenging but vital for risk management. A multidisciplinary review identified common challenges across hazards and proposes a shared framework based on a clear hierarchy of uncertainties, complete forecasts, rigorous model evaluation, and effective communication to support decision-making.
