A cool look at hydroclimatic risk

The climate crisis assertions are revisited through scrutiny of global and regional hydrological data. Atmospheric water vapor, precipitation, and evaporation show natural variability, inconsistent with the rises suggested by IPCC models. Mediterranean and Greek records indicate no systematic occurrences of rainfall extremes, and an overall absence of monotonic rainfall trends. The presence of multi-scale natural fluctuations is emphasized and tools like the climacogram and K-moments are introduced as essential for robust risk analysis. Case studies in Greece on water management in drought conditions and design rainfall at the country level support adaptive stochastics-based strategies over deterministic-model-based ones. The study calls for a rational, evidence-based reassessment of climate narratives and risk management.
