Removing carbon dioxide from the atmosphere is becoming technologically feasible, but will it ever be commercially viable at the scale needed to halt climate change?Ed Butler speaks to Louise Charles of Swiss-based Climeworks - one of the companies that claims it is already turning a profit from the direct capture of carbon from the air. They're selling the CO2 to greenhouses. But what the world really needs to do to stop global warming is bury the stuff in the ground, and who is willing to pay money for that? Ed asks Princeton ecology professor Stephen Pacala, and Gideon Henderson, professor of earth sciences at Oxford University.Producer: Laurence Knight(Picture: A Reykjavik Energy employee stands next to a carbon capture unit designed by the Swiss company Climeworks; Credit: Melanie Stetson Freeman/The Christian Science Monitor via Getty Images)

With the threat of climate change looming, and growing ambivalence about whether the world can meet its stringent carbon emissions reduction targets to limit global warming, many people are searching for new solutions. But some people think they’ve already cracked it, as well as the solution to world hunger, simply by growing plants in salt-water. Dr. Dennis Bushnell, NASA's Chief Scientist, explains the potential he sees in the salt-water loving plants, known as halophytes. We'll also hear from two scientists, Dr. Dionysia Lyra and Dr. RK Singh who are working to make that potential a reality, at the Centre for Biosaline Agriculture in Dubai.Producer: Laurence Knight(Picture: Low chenopod shrub, Samphire (Salicornia europaea), a kind of halophyte.

Did China steal the plans for much of its military hardware, like the J20 jet, from Western defence firms? And what has the US been doing to counter Chinese hacking?Ed Butler speaks to Garrett Graff, a journalist for Wired magazine who has been following the twists and turns in US-China cyber relations over the past few years, including a hacking truce secured by President Obama, that broke down after he left the Oval Office. Plus Ian Bremmer, president of the risk consultancy Eurasia Group, explains why he fears that we are seeing a widening split in the tech economy between China and the West, and that this may be paving the way to a more dangerous real-world conflict.(Picture: A J-20 jet performs at Zhuhai Air Show in China; Credit: STR/AFP/Getty Images)
