Assigning historic responsibility for extreme weather events

World Weather Attribution, Nature Climate Change
- The team applied two different statistical methodologies to assign contributions of individual countries’ emissions to an extreme weather event, using the example of the Argentinian heatwave of 2013/14
- A previously published attribution study found that anthropogenic climate change overall made the event approximately five times more likely
- This new analysis shows that when accounting for all historic emissions from 1850 onwards large emitters like the U.S. and the EU made the event approximately 28% and 37%, respectively, more likely
