Scientists at the Swiss Federal Institute of Technology in Zurich modelled the probability of extreme weather events being caused by human activity . They found humans are to blame for the worst heatwaves and floods today . The scientists used a computer model that predicted how much more heat would be needed if global warming was not curbed, with temperatures rising up to five degrees above pre-industrial levels by 2100. Experts warn storms will grow more common as global temperatures rise .
