Williams's book offers a wonderful insight into how climate can transform the landscape across long stretches of time, as well as how delicately balanced are the ecosystems on which we depend. ---PD Smith, Guardian This vivid historical survey by Earth scientist Martin Williams is the result of a lifetime's work. ---Andrew Robinson, Nature When the Sahara Was Green covers the cyclical, gradual desiccation of the Sahara, the changing of its biomes, the nature of its current occupants, and even the question of its future. It's formidably researched . . . but so warmly, approachably written that learning was never so pleasant. ---Steve Donoghue, Open Letters Review A highly accessible book, relatively brief, and filled with interesting facts about geological history. ---Nicole Barbaro, Bookmarked
