Book Description
An insider's look at the science of near-Earth comets and asteroids Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects—its history, applications, and ongoing quest to find near-Earth objects before they find us. In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One such asteroid is thought to have plunged into our planet sixty-five million years ago, triggering a global catastrophe that killed off the dinosaurs. Yeomans provides an up-to-date and accessible guide for understanding the threats posed by near-Earth objects, and also explains how early collisions with them delivered the ingredients that made life on Earth possible. He shows how later impacts spurred evolution, allowing only the most adaptable species to thrive—in fact, we humans may owe our very existence to objects that struck our planet. Yeomans takes readers behind the scenes of today’s efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.

Book Description
Four people are born every second of every day. Conservative estimates suggest that there will be 10 billion people on Earth by 2050. That is billions more than the natural resources of our planet can sustain without big changes in how we use and manage them. So what happens when vast population growth endangers the world’s food supplies? Or our water? Our energy needs, climate, or environment? Or the planet’s biodiversity? What happens if some or all of these become critical at once? Just what is our future? In Tipping Point for Planet Earth, world-renowned scientists Anthony Barnosky and Elizabeth Hadly explain the growing threats to humanity as the planet edges toward resource wars for remaining space, food, oil, and water. And as they show, these wars are not the nightmares of a dystopian future, but are already happening today. Finally, they ask: at what point will inaction lead to the break-up of the intricate workings of the global society? The planet is in danger now, but the solutions, as Barnosky and Hadly show, are still available. We still have the chance to avoid the tipping point and to make the future better. But this window of opportunity will shut within ten to twenty years. Tipping Point for Planet Earth is the wake-up call we need.

Book Description
This is a novel about people who find themselves in the middle of a horrific conflict and how they survive. Their choices affect their families, the people they love, and the course of their lives. Their stories start before the events in Sudan touch them, following them through challenges and triumphs, as they rebuild their lives. What they have in common with the rest of us is that their journeys are about finding out what kind of people they are: Should they try to draw strength from their anger or should they let it go? Is it better to stick with what you know or find the courage to change?

Book Description
Presents a realistic, workable plan for defusing a potentially lethal threat from a rogue asteroid or comet. The explosion of a large meteor over Chelyabinsk, Siberia, in February 2013 is just the latest reminder that planet Earth is vulnerable to damaging and potentially catastrophic collisions with space debris of various kinds. In this informative and forward-looking book, veteran aerospace writer William E. Burrows explains what we can do in the future to avoid far more serious impacts from "Near-Earth Objects" (NEOs), as they are called in the planetary defense community. The good news is that humanity is now equipped with the advanced technology necessary to devise a long-term strategy to protect the planet. Burrows outlines the following key features of an effective planetary defense strategy- * A powerful space surveillance system capable of spotting a serious threat from space at least a year in advance * A space craft "nudge" that would throw a collision-course asteroid off target long before it poses the threat of imminent impact * A weapons system to be used as a last-ditch method to blast an NEO should all else fail. The author notes the many benefits for world stability and increasing international cooperation resulting from a united worldwide effort to protect the planet. Combining realism with an optimistic can-do attitude, Burrows shows that humanity is capable of overcoming a potentially calamitous situation.

Book Description
A “poignant [and] powerful” novel about a 1920s Midwestern community in the aftermath of a devastating tornado (The New Yorker). In March 1925, the worst tornado in the nation’s history will descend without warning on the small town of Marah, Illinois. By nightfall, hundreds will be homeless and hundreds more will lie in the streets, dead or grievously injured. Only one man, Paul Graves, will still have everything he started the day with—his family, his home, and his business, all miraculously intact. This “absolutely gorgeous” novel follows Paul Graves and his young family in the year after the storm as they struggle to comprehend their own fate and that of their devastated town (The New York Times). They watch helplessly as Marah tries to resurrect itself from the ruins and as their friends and neighbors begin to wonder how one family, and only one, could be exempt from terrible misfortune. As the town begins to recover, the family miscalculates the growing resentment and hostility around them with tragic results, in an “extraordinarily moving” portrayal of survivor’s guilt and the frenzy of bereavement following a disaster (Financial Times). “All the big themes are here—chance, fate, loyalty, revenge, guilt, jealousy . . . Inspired by actual events surrounding the 1925 Tri-State tornado, the worst in U.S. history, Southwood’s poignantly penetrating examination of the psychic cost of survival is breathtaking in its depth of understanding.” —Booklist (starred review) “What’s most exciting about Southwood’s debut is her prose, which is reminiscent of Willa Cather’s in its ability to condense the large, ineffable melancholy of the plains into razor-sharp images.” —The Daily Beast
