More than 140 world leaders are gathering in the French capital of Paris for crucial talks aimed at securing a long-term deal to slow man-made global warming.
The UN climate conference -- which runs from November 30 to December 11 -- is under extra-high security after extremists killed 130 people around Paris earlier this month.
Negotiators from 196 countries are seeking an accord that reduces man-made emissions to limit rising sea levels and increasingly extreme weather that is already threatening populations around the world.
UN Secretary-General Ban Ki-moon is meeting French President Francois Hollande on November 29 to discuss the talks, and U.S. President Barack Obama is among scores of other leaders arriving for the conference.
