_ back here at imperial college london, i am with dr fredi 0tto again, she leads the world weather attribution groupt we have seen, extreme weather wise, in the summer of the northern hemisphere this year? so what stood out for me this year were the wildfires. we have seen many, many heatwaves simultaneously in past years, 2018 for example, also 2019. but this year that has been combined with a drought, and in many cases, that led to wildfires on a scale that i have not really seen in europe. i know, as a weather presenter, meteorologist, that covering these stories, i get comments sent to me, people saying, "it's just summer, it gets hot in summer, you're taking the fun out of summer." do you get comments like that, do they get you down? yes, i do get comments like that, and people sent me lists of past heatwaves as if that would prove that climate change doesn't exist — because no—one says that we never had heatwaves without climate change. in the uk it is always, "oh, but it was hot in 1976," which is true, of course there are heatwaves without climate change. but with climate change we see many

world, whose aim is to deliver rapid analysis of extreme weather and how much more likely it is because of climate change. well, with me now is dr freddie 0tto, who leads the world weather attribution groupmost important question is what did you learn about the link between that uk heatwave and climate change? i think the main results from that study were that this heatwave would have been four degrees cooler, if it would've happened at the beginning of the industrial revolution — or in other words, a heatwave like this has been made at least ten times more likely because of human—induced climate change. so, basically, we would not have seen a heatwave like this if it wasn't for climate change. how are you able to do an analysis and come up with the results so quickly? because i can remember the time when it would take months, even sometimes years, to find the link between climate change and extreme weather. and yet this, your study, came out a week after the uk heatwave. so, how so quick? all our methods are peer—reviewed, so we are not actually doing something new scientifically, we just apply methods that have been tested many times to a new event. and the other thing — and that's pro
