For example, scientists now say the unprecedented heat and wildfires across the northern hemisphere in 2018 “could not have occurred without human-induced climate change”. The deluge delivered in the US by Hurricane Harvey in 2017 was made three times more likely by climate change. Natural variability would cause some extreme weather, even without global heating, but our impacts on the climate make such extremes more likely. Carbon Brief analysed more than 230 studies and found 95% of heatwaves were made more likely or worse by climate change. With the ‘rapidly accelerating’ likelihood of 40C temperatures in UK, it is now undeniable that global heating is causing more extreme weather.
