Tom Steyer plans spring memoir-manifesto on climate

Tom Steyer — the hedge fund billionaire and former presidential candidate — will be out May 28 with a new book that's part business book, part climate manifesto and part memoir.

Why it matters: Steyer argues that our "surest path to winning the climate war is developing and investing in cleaner tech" that's "Cheaper, Faster, Better" — the book's title.
