Climate Change Mercenaries
Meet the climate change mercenaries - people trying to make a profit out of global warming.
Presenter Justin Rowlatt travels to Greenland where Prime Minister Aleqa Hammond hopes the retreating ice will create business opportunities - such as the successful gold prospecting by Joshua Hughes, chief geologist of Nuna Minerals.
We hear from Christian Bonfils, managing director of Nordic Bulk Carriers, about the opening up the fabled North West shipping passage across the Arctic.
Justin encounters some profitable creepy crawlies - the flies being reared by South African farmer Jason Drew to provide a valuable source of protein, and the sterile mosquitos bred by Hadyn Parry, head of Oxitech, to combat dengue fever.
And it's not just insect farming. Greg Smirin of Climate Corporation explains his firm's weather forecasting services and why they have just got together with agriculturual behemoth Monsanto.
And Justin hears from a pair of winemakers - geologist Prof Richard Selley and general manager Chris White of Denbies wine - about the future for British viticulture.
