Guardian and Observer charity telethon: call our writers to donate

Katharine Viner, Owen Jones and George Monbiot will be among those picking up the phones

Want to talk about the climate crisis with George Monbiot or discuss tumultuous recent political events with Polly Toynbee, Owen Jones or Marina Hyde? Or talk food and drink with Felicity Cloake, beauty with Sali Hughes, or movies with Peter Bradshaw?

A team of Guardian and Observer journalists will be taking calls and donations at our annual charity telethon this Saturday. The cause is the climate emergency and we're raising money for four charities that plant and protect trees, forests and woodlands.
