Extreme event attribution

In general, extreme event attribution, also known as attribution science, evaluates relative contributions of multiple causes of an event, and assigns statistical confidence to that evaluation. Most often, the term is applied to the science of identifying and quantifying the role that human-caused climate change plays in the frequency, intensity, duration, and impacts of individual extreme weather events. Attribution science aims to determine the degree to which such events can be explained by or linked to human-caused global warming, and are not simply due to random climate variability or natural weather patterns.
