Face the Facts  Radio 4, 12.30pm  John Waite explains why Northern Ireland Water made so many of its customers suffer over Christmas and into the New Year. If you recall, after the big December freeze the sudden thaw burst water pipes serving thousands of people who were, as we heard in their own words on news bulletins throughout the period, left without running water for up to and even over a week. Bottled water and standpipes were provided but what Waite uncovers is why the provider was so unprepared for a disaster on such a scale. There's also the question of who now pays the bill.  In Denial: Climate on the Couch  Radio 4, 9.00pm  Jolyon Jenkins (so many and various are this man's programmes on Radio 4 any regular listener is bound to wonder when he sleeps) on why, given all the warnings we get about climate change and its effects, so many people seem so unconcerned. People are finding apparently reasonable arguments to justify travelling on planes, not recycling, not listening. This isn't about people who deny climate change. It's about the climate of opinion. The direr the warning, the less its effect. Fear and guilt don't alter habits. He finds out what does.
