By Newsbreak Producer Matthew Veeran - Climate scientists are now using powerful computer simulations to prove a direct link between human activity and specific extreme weather disasters. By comparing current weather data against a digital model of an unpolluted Earth, researchers can pinpoint exactly how much worse or more likely a specific flood or heatwave was made by global warming. This breakthrough now provides undeniable proof that is already being used in global courtrooms to hold major corporate polluters legally accountable.
