"unless we pay our climate debt, and quickly, we may well find ourselves living in a world of climate rage. "Privately, we already hear the simmering resentment of diplomats whose countries bear the costs of our emissions," Senator John Kerry observed recently. "I can tell you from my own experience: It is real, and it is prevalent. It's not hard to see how this could crystallize into a virulent, dangerous, public anti-Americanism. That's a threat too. Remember: The very places least responsible for climate change and least equipped to deal with its impacts will be among the very worst affected." That, in a nutshell, is the argument for climate debt."
