In the tradition of Elizabeth Kolbert and Barry Lopez, a powerful, poetic and deeply absorbing account of the “lung” at the top of the world.For the last fifty years, the trees of the boreal forest have been moving north. The Treeline takes us along this critical frontier of our warming planet from Norway to Siberia, Alaska to Greenland, to meet the scientists, residents and trees confronting huge geological changes. Blending reportage with the latest science, The Treeline is a story of what might soon be the last forest left and what that means for the future of all life on earth.A Macmillan Audio production from St. Martin's Press
