© Crown copyright Met OfficeHow can JULES contribute to currentIPCC and next CCRA?• Both IPCC and CCRA take a fragmented, sectorfocussedapproach• Often the user-focussed impacts work done quickly tocustomer timescales not scientific ones!• Need for a robust, scientifically-proven tool that can beeasily and rapidly applied• Individual sectors (food, water, energy, etc) generallyexamined independently of each other (so inconsistent)• Real world more integrated• Physical interdependencies• Socio-economic interdependencies• As a process-based model of terrestrial systems, JULEScan be a framework for accounting for physicalinterdependencies• Very little work done on detection and attribution ofimpacts
