"Grantham – who occupies a legendary place in the world of finance for predicting all the major stock market bubbles of recent decades (and doing very well in the process) – had decided, after 15 years of low-key environmental philanthropy, to, as he puts it, "walk the walk". From where he stands, this bubble, the "carbon bubble", is the biggest he's seen. "We're already in a bad place. The worst accidents are [only] 20, 30, 40 years from now." Such apocalyptic talk is often the preserve of deep-green doom-mongers – the kind of talk that has led many to reject environmentalism. But Grantham insists he's guided "by the facts alone".
