Astrophysicist Adam Frank traces the question of alien life and intelligence from the ancient Greeks to the leading thinkers of our own time, and shows how we as a civilization can only hope to survive climate change if we recognize what science has recently discovered: that we are just one of ten billion trillion planets in the Universe, and it’s highly likely that many of those planets hosted technologically advanced alien civilizations. What’s more, each of those civilizations must have faced the same challenge of civilization-driven climate change.Written with great clarity and conviction, Light of the Stars builds on the inspiring work of pioneering scientists such as Frank Drake and Carl Sagan, whose work at the dawn of the space age began building the new science of astrobiology; Jack James, the Texas-born engineer who drove NASA’s first planetary missions to success; Vladimir Vernadsky, the Russian geochemist who first envisioned the Earth’s biosphere; and James Lovelock and Lynn Margulis, who invented Gaia theory. Frank recounts the perilous journey NASA undertook across millions of miles of deep space to get its probes to Venus and Mars, yielding our first view of the cosmic laws of planets and climate that changed our understanding of our place in the universe.Thrilling science at the grandest of scales, Light of the Stars explores what may be the largest question of all: What can the likely presence of life on other worlds tell us about our own fate?

    His conclusions are stark: the ice caps are melting. Following the hottest summer on record, sea ice in September 2016 was the thinnest in recorded history. There is now the probability that within a few years, the North Pole will be ice-free for the first time in 10,000 years, entering what some call the "Arctic death spiral." As sea ice, as well as land ice on Greenland and Antarctica, continues to melt, the rise in sea levels will devastate coastal communities across the world. The collapse of summer ice in the Arctic will release large amounts of methane currently trapped by offshore permafrost. Methane has twenty-three times greater greenhouse warming effect per molecule than CO2; an ice-free arctic summer will therefore have an albedo effect nearly equivalent to that of the last thirty years. A sobering but urgent and engaging book, A Farewell to Ice shows us ice's role on our planet, its history, and the true dimensions of the current global crisis, offering readers concrete advice about what they can do and what must be done.

    (We can!)

    In an age of extinction and pandemics, our relationship with the other species on our planet has become unsustainable. What if we took animals' experiences seriously - how would we eat, think and live differently? Henry Mance sets out on a personal quest to see if there is a fairer way to live alongside other species. He goes to work in an abattoir and on a farm to investigate the reality of eating meat and dairy. He explores our dilemmas around hunting wild animals, over-fishing the seas, visiting zoos, saving wild spaces and owning pets. He meets the chefs, farmers, activists, philosophers, scientists and tech visionaries who are redefining how we think about animals. This is not a book about what animals can do for us, but what we can do for animals.

    Back in Sydney his partner Ellie waits for the results of her latest round of IVF treatment.That result, when it comes, will change both their lives and propel them into a future neither could have predicted. In a collapsing England Adam will battle to survive an apocalyptic storm. Against a backdrop of growing civil unrest at home, Ellie will discover a strange affinity with beekeeping. In the aftermath of a pandemic, a young man finds solace in building virtual recreations of the dead. And new connections will be formed from the most unlikely beginnings.Clade is the story of one family in a radically changing world, a place of loss and wonder where the extraordinary mingles with the everyday. Haunting, lyrical and unexpectedly hopeful, it is the work of a writer in command of the major themes of our time.

    Now, Haskell brings his powers of observation to the biological networks that surround all species, including humans. Haskell repeatedly visits a dozen trees around the world, exploring the trees connections with webs of fungi, bacterial communities, cooperative and destructive animals, and other plants. An Amazonian ceibo tree reveals the rich ecological turmoil of the tropical forest, along with threats from expanding oil fields. Thousands of miles away, the roots of a balsam fir in Canada survive in poor soil only with the help of fungal partners. These links are nearly two billion years old: the fir s roots cling to rocks containing fossils of the first networked cells. By unearthing charcoal left by Ice Age humans and petrified redwoods in the Rocky Mountains, Haskell shows how the Earth s climate has emerged from exchanges among trees, soil communities, and the atmosphere. Now humans have transformed these networks, powering our societies with wood, tending some forests, but destroying others. Haskell also attends to trees in places where humans seem to have subdued nature a pear tree on a Manhattan sidewalk, an olive tree in Jerusalem, a Japanese bonsai demonstrating that wildness permeates every location. Every living being is not only sustained by biological connections, but is made from these relationships. Haskell shows that this networked view of life enriches our understanding of biology, human nature, and ethics. When we listen to trees, nature s great connectors, we learn how to inhabit the relationships that give life its source, substance, and beauty."

    The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.

    The ice sheet that covers it is 700 miles wide and 1,500 miles long, and is composed of nearly three quadrillion tons of ice. For the last 150 years, explorers and scientists have sought to understand Greenland--at first hoping that it would serve as a gateway to the North Pole, and later coming to realize that it contained essential information about our climate. Locked within this vast and frozen white desert are some of the most profound secrets about our planet and its future. Greenland's ice doesn't just tell us where we've been. More urgently, it tells us where we're headed.In The Ice at the End of the World, Jon Gertner explains how Greenland has evolved from one of earth's last frontiers to its largest scientific laboratory. The history of Greenland's ice begins with the explorers who arrived here at the turn of the twentieth century--first on foot, then on skis, then on crude, motorized sleds--and embarked on grueling expeditions that took as long as a year and often ended in frostbitten tragedy. Their original goal was simple: to conquer Greenland's seemingly infinite interior. Yet their efforts eventually gave way to scientists who built lonely encampments out on the ice and began drilling--one mile, two miles down. Their aim was to pull up ice cores that could reveal the deepest mysteries of earth's past, going back hundreds of thousands of years.Today, scientists from all over the world are deploying every technological tool available to uncover the secrets of this frozen island before it's too late. As Greenland's ice melts and runs off into the sea, it not only threatens to affect hundreds of millions of people who live in coastal areas. It will also have drastic effects on ocean currents, weather systems, economies, and migration patterns.Gertner chronicles the unfathomable hardships, amazing discoveries, and scientific achievements of the Arctic's explorers and researchers with a transporting, deeply intelligent style--and a keen sense of what this work means for the rest of us. The melting ice sheet in Greenland is, in a way, an analog for time. It contains the past. It reflects the present. It can also tell us how much time we might have left.

    Ben Rawlence's 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. Only the hardest species survive at these latitudes including the ice-loving Dahurian larch of Siberia, the antiseptic Spruce that purifies our atmosphere, the Downy birch conquering Scandinavia, the healing Balsam poplar that Native Americans use as a cure-all and the noble Scots Pine that lives longer when surrounded by its family.It is a journey of wonder and awe at the incredible creativity and resilience of these species and the mysterious workings of the forest upon which we rely for the air we breathe. 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.

    Most conservationists and environmentalists share this view. But what if the traditional view of ecology is wrong—what if true environmentalists should be applauding the invaders? In The New Wild, Pearce goes on a journey across six continents to rediscover what conservation in the twenty-first century should be about. Pearce explores ecosystems from remote Pacific islands to the United Kingdom, from San Francisco Bay to the Great Lakes, as he digs into questionable estimates of the cost of invader species and reveals the outdated intellectual sources of our ideas about the balance of nature. Pearce acknowledges that there are horror stories about alien species disrupting ecosystems, but most of the time, the tens of thousands of introduced species usually swiftly die out or settle down and become model eco-citizens. The case for keeping out alien species, he finds, looks increasingly flawed. As Pearce argues, mainstream environmentalists are right that we need a rewilding of the earth, but they are wrong if they imagine that we can achieve that by reengineering ecosystems. Humans have changed the planet too much, and nature never goes backward. But a growing group of scientists is taking a fresh look at how species interact in the wild. According to these new ecologists, we should applaud the dynamism of alien species and the novel ecosystems they create. In an era of climate change and widespread ecological damage, it is absolutely crucial that we find ways to help nature regenerate. Embracing the new ecology, Pearce shows us, is our best chance. To be an environmentalist in the twenty-first century means celebrating nature’s wildness and capacity for change.

    But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

    Although it is impossible to predict exactly when the most dramatic effects of global warming will be felt, Emanuel argues that we can be confident that we face real dangers.

    Behind that groundbreaking thought experiment was his hope that we would be inspired to find a way to add humans back to this vision of a restored, healthy planet-only in harmony, not mortal combat, with the rest of nature.But with a million more of us every 4 1/2 days on a planet that’s not getting any bigger, and with our exhaust overheating the atmosphere and altering the chemistry of the oceans, prospects for a sustainable human future seem ever more in doubt. For this long awaited follow-up book, Weisman traveled to more than 20 countries to ask what experts agreed were probably the most important questions on Earth — and also the hardest: How many humans can the planet hold without capsizing? How robust must the Earth’s ecosystem be to assure our continued existence? Can we know which other species are essential to our survival? And, how might we actually arrive at a stable, optimum population, and design an economy to allow genuine prosperity without endless growth?Weisman visits an extraordinary range of the world’s cultures, religions, nationalities, tribes, and political systems to learn what in their beliefs, histories, liturgies, or current circumstances might suggest that sometimes it’s in their own best interest to limit their growth. The result is a landmark work of reporting: devastating, urgent, and, ultimately, deeply hopeful.By vividly detailing the burgeoning effects of our cumulative presence, Countdown reveals what may be the fastest, most acceptable, practical, and affordable way of returning our planet and our presence on it to balance. Weisman again shows that he is one of the most provocative journalists at work today, with a book whose message is so compelling that it will change how we see our lives and our destiny.

    It is a true existential crisis. Those alive today will decide the fate of humanity. Meanwhile, the leaders of the most powerful state in human history are dedicating themselves with passion to destroying the prospects for organized human life. At the same time, there is a solution at hand, which is the Green New Deal. Putting meat on the bones of the Green New Deal starts with a single simple idea: we have to absolutely stop burning fossil fuels to produce energy within the next 30 years at most; and we have to do this in a way that also supports rising living standards and expanding opportunities for working people and the poor throughout the world. This version of a Green New Deal program is, in fact, entirely realistic in terms of its purely economic and technical features. The real question is whether it is politically feasible. Chomsky and Pollin examine how we can build the political force to make a global Green New Deal a reality.
