That works out at $143 billion every year, since 2000 according to scientists at Victoria University of Wellington in New Zealand. They analysed 185 extreme weather events from 2000 to 2019 using an approach called ‘extreme event attribution’. It looks at the influence of CO2 emissions on extreme weather events, helping scientists to work out how much of the associated cost was climate-related. They found that human-made climate change was behind 53% of the damage.
