In this, our final episode, we look back at the highs and lows of the past five months. Have the Guardian's original campaign targets, the Wellcome Trust and the Gates Foundation, budged on divestment? Will it push political action at the climate summit in Paris, just six months away? Does the incoming new editor-in-chief Kath Viner even want to continue? As Alan Rusbridger packs his office the team gather one last time to pick over the bones of the project and work out whether they managed to move the needle on climate change.
