What signals should we look for? Looking for early warning signs takes more than a keen eye. Collaborating with the Norwegian University of Science and Technology in Trondheim and the University of Southampton in the United Kingdom, Ole Jonny Klakegg, Terry Williams, Derek Walker, Bjørn Andersen, and Ole Morten Magnussen have expanded on their research of governance frameworks and guidelines as well as provided interviews with experts and case studies from Australia, Norway, and the United Kingdom.
