Artists sign petition
Artists are doing their bit for the planet as politicians and environmental campaigners prepare to converge on Paris for COP21, the United Nations conference on climate change (30 November-11 December). Olafur Eliasson, Yoko Ono, Cornelia Parker and Gavin Turk are among more than 300 signatories of an open letter to Christiana Figueres, the UN’s climate chief, and Laurent Fabius, the French foreign minister and president of the COP21.
