Madeleine Finlay hears from the biodiversity and environment reporter Patrick Greenfield, who is reporting for the Guardian from Cop28 in Dubai. He describes the rollercoaster first week of highs and lows, which included an important agreement on loss and damage and a tetchy press conference from the summit president, Sultan Al Jaber. He also sets out what is still on the table as the second week of negotiations gets under way • This episode was amended on 7 December to reflect the fact that Sheikh Ahmed did not want to be interviewed.
