Poster presented at Our Common Future under Climate Change, July 2015 The breadth of user communities and technical information providers poses many new challenges. Precise technical language is clearly needed to provide full and accurate documentation of the methods and technologies used to collect and process data. The challenges of conveying complex information is compounded by the complex and evolving state of our knowledge. There is a steady flow of events, technical innovations, and scientific advances which continually update our knowledge and expectations. CLIPC is developing a knowledge organisation framework, exploiting standards such as the “Simple Knowledge Organisation System (SKOS)”, to provide a seamless access to climate information.
