French foreign affairs minister says that a U.N. conference on climate in Paris at the end of the year will also be a "conference for peace," given the threat to the world's security from global warming.

Government officials from several African and island nations gathered in Paris Wednesday to discuss the implications of climate change for defense.

"Climate and international security are closely linked," French Foreign Minister Laurent Fabius said. Major droughts, floods and famines lead people to forced migration and "increase the risk of conflicts," he said.

Transition to renewable energy will help ease power struggles over the control of oil and natural gas resources, Fabius added.

France is preparing to host a major U.N. conference on climate from Nov. 30 to Dec. 11.
