There's a curious irony at the heart of climate change. We, that is, the rich countries, have largely caused the problem. But we aren't the one who are going to suffer the most because of it.
In fact, one of the main reasons we are as rich as we are is because we have burnt the most fossil fuels. Britain, for example, was the home of the largely-coal-powered Industrial revolution, and because we got an early lead on burning coal, we are not only relatively well off, we also lead the world in historical emissions. In total, throughout history, the British have emitted more carbon per head of population than anyone else.
