she was shocked by the results come on as an x. team it's of and if you look at extreme heat waves in summer they might be six degrees celsius above normal but not twenty degrees seventy two and logical terms it was a really really strain event extremis i guess so has built a computer network to process the huge volume of data her climate models involve it allows her to calculate how much climate changes increase the probability of an extreme weather event like here in the arctic. and does it get this in the in file in this case or result. showed that without climate change this kind of weather event would have been practically impossible this was the greatest increase in probability that we've seen to date on average human induced climate change made it three hundred times more probable shine and. conversely we need a link auto and her team can also prove
