French President Francois Hollande, addressing the Commonwealth summit in Malta as head of the climate conference's host nation, called for humanity to unite in the fight against global warming.
"Man is the worst enemy of man. We can see it with terrorism," said Hollande, who spoke after leading ceremonies in Paris to mourn the victims of the November 13 terror attacks in the French capital.

"This is virtually the last political milestone before we meet in Paris," he noted.
