What are the economic implications of the US President's withdrawal from the global climate change deal? And why do many big oil companies and some Republicans oppose his move?

Presenter Ed Butler gets the views of former president of the Shell Oil Company John Hofmeister, the former head of George W Bush's Environmental Protection Agency Christine Todd Whitman, and the Greenpeace senior climate advisor Charlie Kronick.

Plus actress and model Lily Cole explains why she is backing the Project Literacy Lab plan.
