Mumbai was hit, earlier this month, by what was described as the heaviest downpour to afflict the Indian city since 2005. The resultant flooding delayed trains and planes and spurred the city’s administrator’s to declare a holiday. The floods coincided with a heatwave in Europe, which scientists from the World Weather Attribution group said had been made about 4°C hotter than would have been the case in the absence of climate change, attributed to human activity.
