Presidents and prime ministers, secretaries and kings are in Egypt for the United Nations annual climate change negotiations. And when world leaders talk about climate change, they evoke one group more than any other: children.
The plight of future generations, and the need to protect today's children from a future made unlivable by global warming, is at the moral heart of international climate negotiations. The United Nations estimates about a billion children are at extremely high risk because of climate change, whether that's because of rising seas, heavy rain, drought or deadly heat waves.
