An argument that we have a moral duty to explore other planets and solar systems--because human life on Earth has an expiration date. Inevitably, life on Earth will come to an end, whether by climate disaster, cataclysmic war, or the death of the sun in a few billion years. To avoid extinction, we will have to find a new home planet, perhaps even a new solar system, to inhabit. In this provocative and fascinating book, Christopher Mason argues that we have a moral duty to do just that. As the only species aware that life on Earth has an expiration date, we have a responsibility to act as the shepherd of life-forms--not only for our species but for all species on which we depend and for those still to come (by accidental or designed evolution). Mason argues that the same capacity for ingenuity that has enabled us to build rockets and land on other planets can be applied to redesigning biology so that we can sustainably inhabit those planets. And he lays out a 500-year plan for undertaking the massively ambitious project of reengineering human genetics for life on other worlds. As they are today, our frail human bodies could never survive travel to another habitable planet. Mason describes the toll that long-term space travel took on astronaut Scott Kelly, who returned from a year on the International Space Station with changes to his blood, bones, and genes. Mason proposes a ten-phase, 500-year program that would engineer the genome so that humans can tolerate the extreme environments of outer space--with the ultimate goal of achieving human settlement of new solar systems. He lays out a roadmap of which solar systems to visit first, and merges biotechnology, philosophy, and genetics to offer an unparalleled vision of the universe to come.

Why a warmer climate may be humanity’s longest-lasting legacy The human impact on Earth's climate is often treated as a hundred-year issue lasting as far into the future as 2100, the year in which most climate projections cease. In The Long Thaw, David Archer, one of the world’s leading climatologists, reveals the hard truth that these changes in climate will be "locked in," essentially forever. If you think that global warming means slightly hotter weather and a modest rise in sea levels that will persist only so long as fossil fuels hold out (or until we decide to stop burning them), think again. In The Long Thaw, David Archer predicts that if we continue to emit carbon dioxide we may eventually cancel the next ice age and raise the oceans by 50 meters. A human-driven, planet-wide thaw has already begun, and will continue to impact Earth’s climate and sea level for hundreds of thousands of years. The great ice sheets in Antarctica and Greenland may take more than a century to melt, and the overall change in sea level will be one hundred times what is forecast for 2100. By comparing the global warming projection for the next century to natural climate changes of the distant past, and then looking into the future far beyond the usual scientific and political horizon of the year 2100, Archer reveals the hard truths of the long-term climate forecast. Archer shows how just a few centuries of fossil-fuel use will cause not only a climate storm that will last a few hundred years, but dramatic climate changes that will last thousands. Carbon dioxide emitted today will be a problem for millennia. For the first time, humans have become major players in shaping the long-term climate. In fact, a planetwide thaw driven by humans has already begun. But despite the seriousness of the situation, Archer argues that it is still not too late to avert dangerous climate change--if humans can find a way to cooperate as never before. Revealing why carbon dioxide may be an even worse gamble in the long run than in the short, this compelling and critically important book brings the best long-term climate science to a general audience for the first time. With a new preface that discusses recent advances in climate science, and the impact on global warming and climate change, The Long Thaw shows that it is still not too late to avert dangerous climate change—if we can find a way to cooperate as never before.

A penetrating take on how our planet would respond without the relentless pressure of the human presence

The instant New York Times bestseller and companion book to the PBS series. “Absolutely brilliant . . . A necessary and moving work.” —Eddie S. Glaude, Jr., author of Begin Again “Engaging. . . . In Gates’s telling, the Black church shines bright even as the nation itself moves uncertainly through the gloaming, seeking justice on earth—as it is in heaven.” —Jon Meacham, New York Times Book Review From the New York Times bestselling author of Stony the Road and one of our most important voices on the African American experience comes a powerful new history of the Black church as a foundation of Black life and a driving force in the larger freedom struggle in America. For the young Henry Louis Gates, Jr., growing up in a small, residentially segregated West Virginia town, the church was a center of gravity—an intimate place where voices rose up in song and neighbors gathered to celebrate life's blessings and offer comfort amid its trials and tribulations. In this tender and expansive reckoning with the meaning of the Black Church in America, Gates takes us on a journey spanning more than five centuries, from the intersection of Christianity and the transatlantic slave trade to today’s political landscape. At road’s end, and after Gates’s distinctive meditation on the churches of his childhood, we emerge with a new understanding of the importance of African American religion to the larger national narrative—as a center of resistance to slavery and white supremacy, as a magnet for political mobilization, as an incubator of musical and oratorical talent that would transform the culture, and as a crucible for working through the Black community’s most critical personal and social issues. In a country that has historically afforded its citizens from the African diaspora tragically few safe spaces, the Black Church has always been more than a sanctuary. This fact was never lost on white supremacists: from the earliest days of slavery, when enslaved people were allowed to worship at all, their meetinghouses were subject to surveillance and destruction. Long after slavery’s formal eradication, church burnings and bombings by anti-Black racists continued, a hallmark of the violent effort to suppress the African American struggle for equality. The past often isn’t even past—Dylann Roof committed his slaughter in the Mother Emanuel AME Church 193 years after it was first burned down by white citizens of Charleston, South Carolina, following a thwarted slave rebellion. But as Gates brilliantly shows, the Black church has never been only one thing. Its story lies at the heart of the Black political struggle, and it has produced many of the Black community’s most notable leaders. At the same time, some churches and denominations have eschewed political engagement and exemplified practices of exclusion and intolerance that have caused polarization and pain. Those tensions remain today, as a rising generation demands freedom and dignity for all within and beyond their communities, regardless of race, sex, or gender. Still, as a source of faith and refuge, spiritual sustenance and struggle against society’s darkest forces, the Black Church has been central, as this enthralling history makes vividly clear.

A Kirkus Reviews Best Nonfiction of 2011 title A bold, far-reaching look at how our actions will decide the planet's future for millennia to come. Imagine a planet where North American and Eurasian navies are squaring off over shipping lanes through an acidified, ice-free Arctic. Centuries later, their northern descendants retreat southward as the recovering sea freezes over again. And later still, future nations plan how to avert an approaching Ice Age... by burning what remains of our fossil fuels. These are just a few of the events that are likely to befall Earth and human civilization in the next 100,000 years. And it will be the choices we make in this century that will affect that future more than those of any previous generation. We are living at the dawn of the Age of Humans; the only question is how long that age will last. Few of us have yet asked, "What happens after global warming?" Drawing upon the latest, groundbreaking works of a handful of climate visionaries, Curt Stager's Deep Future helps us look beyond 2100 a.d. to the next hundred millennia of life on Earth.
