When a 1.4°C Rise Becomes a Massive Risk: How Standard Deviation Drives Heatwave Impacts

A June 2024 heatwave in Western Europe exposed how a modest 1.4 °C temperature increase can dramatically amplify extreme‑value probabilities, especially nighttime lows, because risk is governed by the ratio of temperature shifts to natural variability rather than absolute degrees, challenging traditional stationary design standards.
