The Next 500 Years

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.

Extrapolates scientific fact to speculate on the offerings of the next millenium, including colonization of the Moon and Mars by private industry and the storage of human personalities on computer disk for retrieval after death

Most books about the environment build on dire threats warning of the possible extinction of humanity. Alan Weisman avoids frightening off readers by disarmingly wiping out our species in the first few pages of this remarkable book. He then continues with an astounding depiction of how Earth will fare once we’re no longer around. The World Without Us is a one-of-a-kind book that sweeps through time from the moment of humanity’s future extinction to millions of years into the future. Drawing on interviews with experts and on real examples of places in the world that have already been abandoned by humans—Chernobyl, the Korean DMZ and an ancient Polish forest—Weisman shows both the shocking impact we’ve had on our planet and how impermanent our footprint actually is.

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.

In this extraordinary book, paleoclimatologist Curt Stager shows how what we do to the environment in the next one hundred years will affect not just the next few centuries but the next 100,000 years of human existence. Most of us have accepted that our planet is warming and that humans have played the key role in causing climate change. Yet few of us realize the magnitude of what’s happening. In Deep Future, Curt Stager draws on the planet’s geological history to provide a view of where we may be headed long term. On the bright side, we have already put off the next ice age. But whether we will barrel ahead on a polluting path to a totally ice-free Arctic, miles of submerged coasts or an acidified ocean still remains to be decided. And that decision is ours to make. Deep Future adds a new dimension to the debate—one that will change how we think about what we are doing to our planet.

Fifty years ago, the National Academy of Engineering (NAE) was founded by the stroke of a pen when the National Academy of Sciences Council approved the NAE's articles of organization. Making a World of Difference commemorates the NAE anniversary with a collection of essays that highlight the prodigious changes in people's lives that have been created by engineering over the past half century and consider how the future will be similarly shaped. Over the past 50 years, engineering has transformed our lives literally every day, and it will continue to do so going forward, utilizing new capabilities, creating new applications, and providing ever-expanding services to people. The essays of Making a World of Difference discuss the seamless integration of engineering into both our society and our daily lives, and present a vision of what engineering may deliver in the next half century.

NATIONAL BESTSELLER NEW YORK TIMES BESTSELLER Destined to become a modern classic in the vein of Guns, Germs, and Steel, Sapiens is a lively, groundbreaking history of humankind told from a unique perspective. 100,000 years ago, at least six species of human inhabited the earth. Today there is just one. Us. Homo Sapiens. How did our species succeed in the battle for dominance? Why did our foraging ancestors come together to create cities and kingdoms? How did we come to believe in gods, nations, and human rights; to trust money, books, and laws; and to be enslaved by bureaucracy, timetables, and consumerism? And what will our world be like in the millennia to come? In Sapiens, Dr. Yuval Noah Harari spans the whole of human history, from the very first humans to walk the earth to the radical -- and sometimes devastating -- breakthroughs of the Cognitive, Agricultural, and Scientific Revolutions. Drawing on insights from biology, anthropology, palaeontology, and economics, he explores how the currents of history have shaped our human societies, the animals and plants around us, and even our personalities. Have we become happier as history has unfolded? Can we ever free our behaviour from the heritage of our ancestors? And what, if anything, can we do to influence the course of the centuries to come? Bold, wide-ranging and provocative, Sapiens challenges everything we thought we knew about being human: our thoughts, our actions, our power...and our future.
