'Astonishing ... beautiful, compelling and terrifying' Observer

'Wadhams' writing sparkles ... a lyrical sense of wonder at the natural world ... essential reading ... may be the best reader-friendly account of the greenhouse effect available to date' John Burnside, New Statesman

Ice is beautiful and complex. It regulates our planet's temperature. And it is vanishing - fast. Peter Wadhams, the world's leading expert on sea ice, draws on his lifetime's research in the Arctic region to illuminate what is happening, what it means for the future, and what can be done.

'This most experienced and rational scientist states what so many other researchers privately fear but cannot publicly say' John Vidal, Guardian

'Wadhams brings huge expertise to his subject - and he is an excellent writer' Martin Rees

'Utterly extraordinary' Jonathon Porritt
