United Nations Climate Change Conference

World leaders launched an ambitious attempt on Monday to hold back the earth's rising temperatures, with French President Francois Hollande saying the world was at "breaking point" in the fight against global warming.

They arrived at United Nations climate change talks in Paris accompanied by high expectations and armed with promises to act. After decades of struggling negotiations and the failure of a summit in Copenhagen six years ago, some form of landmark agreement appears all but assured by mid-December. (Reuters)
