BP rising shares, climate change, Iran sanctions

In the podcast this week: Why are BP shares up? And on another positive note for BP, comments made by prominent UK scientists last week in Bonn suggest that the oil spill in the Gulf is not environmentally as bad as first thought. Also in the show: we look at climate change and the opening of the Green Investment Bank in the UK; plus Iran and the continuing battle over sanctions.
With Ed Crooks, Carola Hoyos, Javier Blas and Fiona Harvey.
