Zhengzhou, a central Chinese city, with 10,000,000 inhabitants has been paralysed by record-breaking floods and more rain in one day than it usually gets in a year. So how the climate crisis be tackled? We get analysis from Micheal Mann, distinguished professor of atmospheric science at Penn State University and the author of The New Climate War. Also in the programme, UNESCO has decided to strip Liverpool of World Heritage status, saying new developments resulted in a "serious deterioration" of the historic site. But do these titles mean that much to a city’s prospects or prosperity? We get analysis from Liam Thorp of the Liverpool Echo newspaper. And Peter Jankovskis brings us the latest news from the financial markets.
