The idea for a Dutch climate case came from the book Revolution Justified of the Dutch lawyer Roger Cox, who is also one of the lawyers representing Urgenda. His call to involve the judiciary in averting the climate crisis was published in the Guardian on 14 November 2012. In March 2014 Roger Cox gave a presentation on the climate case at a TEDx conference, shown below. In May 2014 Roger Cox gave a lecture at the legal faculty of the University of Oslo, Norway: it is available here.
