Heatwave made ’twice as likely by climate change’

The unprecedented temperatures seen over Summer 2018 are a sign of things to come  - and a direct result of climate change, according to new Oxford University research. In the newly published report, researchers from the  Environmental Change Institute (ECI) at the School of Geography and Environment, Oxford University , who worked in collaboration with the World Weather Attribution network (WWA) , reveal that climate change more than doubled the likelihood of the European heatwave, which could come to be known as regular summer temperatures. Dr Friederike Otto, Deputy Director of the ECI at the University of Oxford, said: 'What was once regarded as unusually warm weather will become commonplace - in some cases, it already has.' The research compares current temperatures with historical records at seven weather stations in northern Europe - two in Finland, one each in Denmark, the Irish Republic, the Netherlands, Norway and Sweden. These stations were selected because current temperature data could be accessed in real time, and they possess digitised records extending back to the early 1900s. The scientists also used computer models to assess the impact of man-made climate change. For each year in the historical record, the team looked at the hottest consecutive three-day period. For 2018, it was the hottest three days of the year so far - either observed or in the - short-term forecast.
