Our flood defences aren’t fit for the climate we have now

This week’s political fuss over whether the floods in Yorkshire constitute a ‘national emergency’ misses the point. It is too easy to declare an emergency for political purposes, to give the impression that the government is taking an issue seriously. It’s quite obvious that the scenes we have seen this week represent an emergency — the question is whether, once the helicopter visits and photo opportunities have ceased, all is forgotten and the political world moves on to the next emergency.
