The ability to link extreme weather events to climate change has emerged as one of the most significant scientific advancements of the 21st century.This breakthrough has reshaped public discourse and legal frameworks regarding climate impacts, emphasizing the urgent need for action to mitigate these effects.In the early 2000s, climate scientists Myles Allen and Peter Stott began exploring the connection between climate change and extreme weather events.Their pivotal research, published in 2004, demonstrated that human activities had at least doubled the risk of the 2003 European heatwave, marking the inception of a new field known as attribution science.
