22 June 2015, The Carbon Brief, Climate change attribution studies are asking the wrong questions, study says. Scientists are calling for a rethink in the way we seek to understand how climate change affects extreme weather. The latest in so-called attribution studies is to study each individual event by itself, looking for how climate change may have made it stronger or more likely. But a new paper says the methods used in many of these studies underestimate the influence of climate change, and suggests a new approach to identify the “true likelihood of human influence”.
One of the first studies to attribute a single extreme weather event to climate change was published just over a decade ago. Researchers showed that climate change had doubled the chances of the record heatwave Europe experienced in 2003. In the years that followed, many more studies have aimed to provide answers on how climate change is affecting our most brutal weather. But while scientists have been able to attribute events caused by temperature extremes, linking other extreme events like storms and heavy rainfall events has proved more difficult, says a new paper in Nature Climate Change.
