The document describes a 'hazard synthesis' method developed by World Weather Attribution to combine different lines of evidence into a single number representing the influence of climate change on an extreme event's intensity and likelihood. It notes that while this approach is more realistic than using models or observations in isolation, it faces limitations when events would have been impossible in a cooler world or when climate models contradict basic physics, such as the Clausius-Clapeyron relationship. The author emphasizes that human expertise and experience are necessary to evaluate these results, as automated or AI-driven analysis cannot yet account for model deficiencies or data discrepancies.
