LE BOURGET, France – The latest news from the U.N. climate conference in Paris, which runs through Dec. 11.

11:40 a.m.

The head of the World Food Program is warning that hunger linked to climate change may worsen mass migrations, and is hoping for an ambitious international accord to slow global warming.

Ertharin Cousin told The Associated Press that people "will move if they don't have enough to eat." Speaking Wednesday at the climate talks in Paris, she says "food insecurity anywhere is a security challenge everywhere."

Cousin says the U.N. food agency cannot fulfill its promises to eradicate hunger without a global climate accord, and investment in preventive measures such as drought-resistant seeds and water-conserving agriculture.

Man-made global warming is causing worsening droughts and floods that are threatening traditional food sources, she said — especially in the poorest countries, where hunger is already a top problem.
