How scientists are modelling an 'alternative universe' to understand climate change's impact on extreme weather

"Is climate change to blame?" “You're really comparing how the event looked in the present day with how it looked in the counterfactual, in that world where we didn't see industrialisation, we didn't have climate change.” Dr Hope said in order to do that, climate models used different inputs of external factors, inclduing different levels of greenhouse gases and variations of aerosols that are emitted when burning fossil fuels. but it's perhaps a little way away from being talked about.” Climate change appears to be contributing to the increasing number of extreme weather events. “You see an extreme event now, what does that event look like if climate change hadn't ever occurred, but also what would it look like in 20 or 30 years time?,” Dr Hope said. “But I think a lot of it is around helping people visualise what climate change means in things that they've recently experienced.” Attribution science is developing to understand the impacts climate change is having on extreme events.
