The coming hunger: Record food prices put world 'in danger', says UN - World Politics, World - The Independent

Mr Abbassian said the UN agency is concerned by the unpredictability of weather activity, which many experts link to climate change. He said: "There is still room for prices to go up much higher, if for example the dry conditions in Argentina tend to become a drought, and if we start having problems with winterkill in the northern hemisphere for the wheat crops."

One concern, especially in Ukraine and Russia, is that the cold winter, following disastrous droughts and summer fires, will have damaged the seeds for next year's crops, leading to an even more acute crisis than seen last year.
