It's 2050 and at the United Nations in New York, the leaders of the world gather for a make-or-break climate summit. A raft of unprecedented binding measures to precipitate greater climate action globally are under discussion and the world is waiting for the outcome... Mark Little and Carla O'Brien present Tomorrow Tonight a scripted, docu-drama set 27 years in the future guiding viewers through the breaking news moments on a seismic night, as climate change pushes the planet to a moment of crisis. From a studio in Dublin, an impressive panel of experts and augmented-reality graphic explainers decipher a range of complex issues for the audience. Meanwhile a team of roving reporters link live by satellite to the studio, offering analysis and immediate reactions from multiple locations around the world, as they piece together the comprehensive global picture. Throughout the programme we hear about the catastrophic effects of global warming and sea level rise on ordinary families at home and abroad, analyse the global climate refugee crisis that has hit home on Irish shores and meet the Chief Prosecutor of the International Court of Climate Crime as she holds business leaders and politicians alike to account for past actions of denial and delay. The programme will also report on the good news, including the Irish rural economy that has innovated and thrived despite the decline of traditional dairy and livestock farming. And, in Brazil we see a revitalised Amazon rainforest whose fate was placed in the hand of indigenous leaders in the late 2030s.
