Prince Charles has urged world leaders to "think of your grandchildren, as I think of mine" as he demanded greater action to tackle climate change.
"On an increasingly crowded planet humanity faces many threats but none is greater than climate change," the royal told the UN conference in Paris.
Charles called on leaders gathered to take immediate action to tackle rising temperatures, which he said magnify "every hazard and tension of our existence".
"It threatens our ability to feed ourselves, to remain healthy and safe from extreme weather, to manage the natural resources that support our economies, and (impacts the) humanitarian disaster of mass migration and increasing conflict," he said.
Charles, who began his keynote speech with a tribute in French to the victims of the Paris attacks, added: "I can only urge you to think of your grandchildren, as I think of mine, and of those billions of people without a voice."
