science π Climate change blame for extreme weather has limits
World Weather Attribution (WWA) previously linked climate change to an intense South Asian heatwave, making it three times more likely and up to 1Β°C warmer. The science uses computer models comparing pre-industrial to current CO2 levels over 420 ppm. However, experts question if single event attribution is always scientifically possible and confident. Challenges include model limitations, natural variability, and data gaps for local events. Confidence in attribution is higher for long-duration events like heatwaves than for short ones. π‘οΈ
