Billions of dollars are spent on advertising in US presidential election years. We ask Shannon Bond of the Financial Times in New York how much of that money is well-targeted. Also in the programme, Warren Buffett has compared fears about climate change to the hype around the Millennium Bug. We get reaction from Andrew Simms of the London-based think tank the New Weather Institute. We have a special report from the 主播大秀's Laurence Knight on how the element tantalum fuels corruption in Africa. And with the global hop harvest down 40 per cent last year, brewer Darius Darwell from North Brewing tells us what impact it might have on the price of beer.
