Examines how deserts are formed and how they are constantly changing, what animals and plants live there, ways in which humans live in and change deserts.

The little-known history of how the Sahara was transformed from a green and fertile land into the largest hot desert in the world The Sahara is the largest hot desert in the world, equal in size to China or the United States. Yet, this arid expanse was once a verdant, pleasant land, fed by rivers and lakes. The Sahara sustained abundant plant and animal life, such as Nile perch, turtles, crocodiles, and hippos, and attracted prehistoric hunters and herders. What transformed this land of lakes into a sea of sands? When the Sahara Was Green describes the remarkable history of Earth’s greatest desert—including why its climate changed, the impact this had on human populations, and how scientists uncovered the evidence for these extraordinary events. From the Sahara’s origins as savanna woodland and grassland to its current arid incarnation, Martin Williams takes us on a vivid journey through time. He describes how the desert’s ancient rocks were first fashioned, how dinosaurs roamed freely across the land, and how it was later covered in tall trees. Along the way, Williams addresses many questions: Why was the Sahara previously much wetter, and will it be so again? Did humans contribute to its desertification? What was the impact of extreme climatic episodes—such as prolonged droughts—upon the Sahara’s geology, ecology, and inhabitants? Williams also shows how plants, animals, and humans have adapted to the Sahara and what lessons we might learn for living in harmony with the harshest, driest conditions in an ever-changing global environment. A valuable look at how an iconic region has changed over millions of years, When the Sahara Was Green reveals the desert’s surprising past to reflect on its present, as well as its possible future.

Part of an eight-volume set for students, this book examines the past, present, and future of Earth's climate.

I love it. Earle understands the big climate picture and paints it with exceptional clarity. — JAMES HANSEN, director, Climate Science, Awareness and Solutions, Columbia University Earth Institute What's natural, what's caused by humans, and why climate change is a disaster for all A Brief History of the Earth's Climate is an accessible myth-busting guide to the natural evolution of the Earth's climate over 4.6 billion years, and how and why human-caused global warming and climate change is different and much more dangerous. Richly illustrated chapters cover the major historical climate change processes including evolution of the sun, plate motions and continental collisions, volcanic eruptions, changes to major ocean currents, Earth's orbital variations, sunspot variations, and short-term ocean current cycles. As well as recent human-induced climate change and an overview of the implications of the COVID pandemic for climate change. Content includes: Understanding natural geological processes that shaped the climate How human impacts are now rapidly changing the climate Tipping points and the unfolding climate crisis What we can do to limit the damage to the planet and ecosystems Countering climate myths peddled by climate change science deniers. A Brief History of the Earth's Climate is essential reading for everyone who is looking to understand what drives climate change, counter skeptics and deniers, and take action on the climate emergency.

From the oceans to continental heartlands, human activities have altered the physical characteristics of Earth's surface. With Earth's population projected to peak at 8 to 12 billion people by 2050 and the additional stress of climate change, it is more important than ever to understand how and where these changes are happening. Innovation in the geographical sciences has the potential to advance knowledge of place-based environmental change, sustainability, and the impacts of a rapidly changing economy and society. Understanding the Changing Planet outlines eleven strategic directions to focus research and leverage new technologies to harness the potential that the geographical sciences offer.

Hotter and dryer than most parts of the world, the Middle East could soon see climate change exacerbate food and water shortages, aggravate social inequalities, and drive displacement and political destabilization. And as renewable energy eclipses fossil fuels, oil rich countries in the Middle East will see their wealth diminish. Amidst these imminent risks is a call to action for regional leaders. Could countries such as Saudi Arabia, Kuwait, and the United Arab Emirates harness the region's immense potential for solar energy and emerge as vanguards of global climate action? The Power of Deserts surveys regional climate models and identifies the potential impact on socioeconomic disparities, population movement, and political instability. Offering more than warning and fear, however, the book highlights a potentially brighter future--a recent shift across the Middle East toward renewable energy. With his deep knowledge of the region and knack for presenting scientific data with clarity, Dan Rabinowitz makes a sober yet surprisingly optimistic investigation of opportunity arising from a looming crisis.

Plants have profoundly moulded the Earth's climate and the evolutionary trajectory of life. Far from being 'silent witnesses to the passage of time', plants are dynamic components of our world, shaping the environment throughout history as much as that environment has shaped them. In The Emerald Planet, David Beerling puts plants centre stage, revealing the crucial role they have played in driving global changes in the environment, in recording hidden facets of Earth's history, and in helping us to predict its future. His account draws together evidence from fossil plants, from experiments with their living counterparts, and from computer models of the 'Earth System', to illuminate the history of our planet and its biodiversity. This new approach reveals how plummeting carbon dioxide levels removed a barrier to the evolution of the leaf; how plants played a starring role in pushing oxygen levels upwards, allowing spectacular giant insects to thrive in the Carboniferous; and it strengthens fascinating and contentious fossil evidence for an ancient hole in the ozone layer. Along the way, Beerling introduces a lively cast of pioneering scientists from Victorian times onwards whose discoveries provided the crucial background to these and the other puzzles. This understanding of our planet's past sheds a sobering light on our own climate-changing activities, and offers clues to what our climatic and ecological futures might look like. There could be no more important time to take a close look at plants, and to understand the history of the world through the stories they tell. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.
