09:30 Why New Zealand co-founder of Tesla Motors believes electrifying trucks is more important than getting commuters into electric cars.

Ian Wright is a New Zealander engineer who co-founded Tesla Motors with Elon Musk in 2003. But he left after a year to focus on creating a super-fast electric car, which he did, and in recent years has turned his attention to electrifying trucks. His company Wrightspeed, based in Califorina has coverted medium to heavy trucks for Fed Ex and is now applying its technology to heavy-duty rubbish trucks.

McKenzie Funk is an author and journalist who has been investigating the ways people are responding to the effects of climate change. His latest book, The Wreck of the Kulluk details how Royal Dutch Shell tried and failed to begin drilling for oil in the Beaufort sea in the Arctic in 2012. Melting sea ice has made the area more accessible, but the exploratory drilling rig, the Kulluk, was battered by storms and its crew had to be rescued. Shell however, is planning to return to the remote Chukchi sea off Northwestern Alaska, and has been granted conditional approval by the US government to begin exploratory drilling.
