The ability to link extreme weather events directly to climate change represents one of the most significant advancements in climate science this century.Pioneering work by scientists like Myles Allen and Peter Stott has laid the groundwork for a new field of research that quantifies the influence of human activities on specific weather events, fundamentally changing our understanding of climate impacts.In 2003, physicist Myles Allen experienced severe flooding in Oxford, UK, which prompted him to question why meteorologists were hesitant to attribute such events to climate change.Around the same time, Peter Stott found himself trapped in a deadly heatwave in Italy, which further fueled his desire to explore the connection between climate change and extreme weather events.Together, they utilized climate models to simulate two scenarios: one reflecting the climate of 2003 and another without human-induced warming.Their groundbreaking 2004 paper in Nature concluded that human activities had at least doubled the risk of the heatwave occurring, marking a pivotal moment in climate science.
