When a devastating heat wave, hurricane, flood or wildfire strikes, people often want to know: How much did human-caused climate change influence this event, if at all? For many years, scientists could answer that question only in general terms. They knew that human-caused climate change was increasing the frequency or intensity of some kinds of extreme weather, but determining its influence on a particular event was much more difficult.
