Naomi Klein is by all accounts a wonderful person – warm, low-key, modest, committed and enormously hard-working. She also looks terrific in a crisp white shirt, which is what she wore for a recent photo shoot for Vogue. Not that there’s anything wrong with that. Vogue is interested in fashionable intellectuals, and right now there’s no intellectual more fashionable than Ms. Klein. She told Vogue that her new book, This Changes Everything, is “a book about climate change for people who don’t read books about climate change.”
