Book Description
The cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? On 13 March 1989, six million people in Canada went without electricity for many hours: a large explosion on the sun was discovered as the cause of this blackout. Such explosions occur above sunspots, dark features on the surface of the Sun that have been observed through telescopes since the time of Galileo. The number of sunspots has been found to wax and wane over a period of 11 years. Although this cycle was discovered less than two centuries ago, it is becoming increasingly important for us as human society becomes more dependent on technology. For nearly a century after its discovery, the cause of the sunspot cycle remained completely shrouded in mystery. The 1908 discovery of strong magnetic fields in sunspots made it clear that the 11-year cycle is the magnetic cycle of the sun. It is only during the last few decades that major developments in plasma physics have at last given us the clue to the origins of the cycle and how the large explosions affecting the earth arise. Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.

Book Description
Black Nature is the first anthology to focus on nature writing by African American poets, a genre that until now has not commonly been counted as one in which African American poets have participated. Black poets have a long tradition of incorporating treatments of the natural world into their work, but it is often read as political, historical, or protest poetry--anything but nature poetry. This is particularly true when the definition of what constitutes nature writing is limited to work about the pastoral or the wild. Camille T. Dungy has selected 180 poems from 93 poets that provide unique perspectives on American social and literary history to broaden our concept of nature poetry and African American poetics. This collection features major writers such as Phillis Wheatley, Rita Dove, Yusef Komunyakaa, Gwendolyn Brooks, Sterling Brown, Robert Hayden, Wanda Coleman, Natasha Trethewey, and Melvin B. Tolson as well as newer talents such as Douglas Kearney, Major Jackson, and Janice Harrington. Included are poets writing out of slavery, Reconstruction, the Harlem Renaissance, the Black Arts Movement, and late twentieth- and early twenty-first-century African American poetic movements. Black Nature brings to the fore a neglected and vital means of considering poetry by African Americans and nature-related poetry as a whole. A Friends Fund Publication.

Book Description
Reissued on the tenth anniversary of its publication, this classic work on our environmental crisis features a new introduction by the author, reviewing both the progress and ground lost in the fight to save the earth. This impassioned plea for radical and life-renewing change is today still considered a groundbreaking work in environmental studies. McKibben's argument that the survival of the globe is dependent on a fundamental, philosophical shift in the way we relate to nature is more relevant than ever. McKibben writes of our earth's environmental cataclysm, addressing such core issues as the greenhouse effect, acid rain, and the depletion of the ozone layer. His new introduction addresses some of the latest environmental issues that have risen during the 1990s. The book also includes an invaluable new appendix of facts and figures that surveys the progress of the environmental movement. More than simply a handbook for survival or a doomsday catalog of scientific prediction, this classic, soulful lament on Nature is required reading for nature enthusiasts, activists, and concerned citizens alike.
