By 2030, experts predict two-thirds of people living on this planet will not have enough water, a situation expected to result in the deaths of millions and an unprecedented rise in military conflicts. Can we as individuals hope to reverse these dire predictions? Award-winning author and water activist Florencia Ramirez believes we can if our conservation efforts focus on the 70 percent of freshwater flowing to the fields and ranches that grow our food. Eat Less Water takes the listener on a journey to meet America's food producers growing food with less water.

For almost 500 years, human beings have been finding ways to circle the Earth - by sail, steam, or liquid fuel; by cycling, driving, flying, going into orbit, even by using their own bodily power. The story begins with the first centuries of circumnavigation, when few survived the attempt: In 1519, Ferdinand Magellan left Spain with five ships and 270 men, but only one ship and 35 men returned, not including Magellan, who died in the Philippines. Starting with these dangerous voyages, Joyce Chaplin takes us on a trip of our own as we travel with Francis Drake, William Dampier, Louis-Antoine de Bougainville, and James Cook.

Tropische Wälder in der Antarktis. Ein Wasserfall von unvorstellbarer Größe, der das trockene Mittelmeerbecken mit Leben füllt. Eine Python, die in der kenianischen Savanne frühe Verwandte des Menschen auf Bäume jagt. Die Vergangenheit ist lebendig – und sie hinterlässt Spuren. Der Paläontologe Thomas Halliday entziffert sie origineller denn je. Anschaulich lässt er verlorene Welten wiederaufleben, erklärt, wie Ökosysteme entstehen und verschwinden, wie alte Spezies durch neue verdrängt werden, wie Lebewesen wandern, sich anpassen und entwickeln.

As scientific and observational evidence on global warming piles up every day, questions of economic policy in this central environmental topic have taken center stage. But as author and prominent Yale economist William Nordhaus observes, the issues involved in understanding global warming and slowing its harmful effects are complex and cross disciplinary boundaries. For example, ecologists see global warming as a threat to ecosystems, utilities as a debit to their balance sheets, and farmers as a hazard to their livelihoods.

Frank Ledwidge offers a sweeping look at the history of air warfare, introducing the major battles, crises, and controversies where air power has taken center stage and exploring the changes in technology and air power capabilities over time. Considering whether bombing has ever been truly effective, he discusses whether wars can be won from the air and concludes by analyzing whether there is a future for manned air power, or if it is inevitable that drones will dominate 21st-century war in the air.

Every week, Heatmap News Executive Editor Robinson Meyer and Princeton University Professor and energy systems expert Jesse Jenkins make sense of the biggest shift of our time -- navigating the energy transition away from fossil fuels. Drawing on their years of experience reporting on and researching climate change and decarbonization, Meyer and Jenkins unpack the most important issues of the week and how the impacts of climate change and efforts to address it are transforming our economy, politics, and society at large.

"Our Choice gathers in one place all of the most effective solutions that are available now and that, together, will solve this crisis. It is meant to depoliticize the issue as much as possible and inspire readers to take action - not only on an individual basis but as participants in the political processes by which every country, and the world as a whole, makes the choice that now confronts us." (Al Gore, from the Introduction)

At stake in the "Science Wars" that have raged in academe and in the media is nothing less than the standing of science in our culture. One side argues that science is a "social construct," that it does not discover facts about the world, but rather constructs artifacts disguised as objective truths. This view threatens the authority of science and rejects science's claims to objectivity, rationality, and disinterested inquiry. Drawing Out Leviathan examines this argument in the light of some major debates about dinosaurs.

Ever since we first started discovering dinosaurs in the early 1800s, our obsession for uncovering everything about these creatures has been insatiable. Each generation has made huge strides in trying to better our understanding of these animals, and in the past 20 years, we have made more discoveries than in the previous 200. There have been extraordinary advances in palaeontological methods, and ever more dinosaur fossils promise a landslide of new data and huge leaps forward in our understanding of these incredible animals.

Are you worried about the effects of climate change on our environment? Want to help but don't know where to start? Environmental activist Natalie Fee's new handbook to green living will help you to make small lifestyle changes that will make a big difference to our planet.

This is an audiobook for those who want to understand better how the waters surrounding us affect our daily lives, how it imperceptibly but crucially shapes our actions and has shaped our landscape for millennia. It's for anyone who knows and loves our coast and who wants to understand, discover, surf or sail it better. Inspired by his own witnessing of the power of the sea through travelling around Britain's coastline in a panel van with his young family, William Thomson tells the story of the cycles of the sea.

The Lee Weather Team hosts a fast-paced weekly podcast that tackles hot topics (and cold!) plus what’s trending in meteorology, science and climate. The show isn't limited to hard science as our hosts and guests tug at your emotions from stories out in the elements. The Lee Weather team features Matt Holiner of Lee Enterprises' Midwest group in Chicago, Kirsten Lang of the Tulsa World in Oklahoma, Joe Martucci of the Press of Atlantic City, N.J., and Sean Sublette of the Richmond Times-Dispatch in Virginia.

The Brilliant Abyss tells the story of our relationship with the deep sea – how we imagine, explore and exploit it. It captures the golden age of discovery we are currently in and looks back at the history of how we got here, while also looking forward to the unfolding new environmental disasters that are taking place miles beneath the waves, far beyond the public gaze.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

The Arctic Treeline - the northern limit of the boreal forest that encircles the globe in an almost unbroken green ring - is the second largest biome on our planet. At this little-known frontline of climate change, the trees have been creeping towards the pole for 50 years already. Six of the tree species that populate these forests (larch, spruce, mountain ash, downy birch, balsam poplar and Scots pine) form the central protagonists of Ben Rawlence's story.

In Waves, Fredric Raichlen traces the evolution of waves, from their generation in the deep ocean to their effects on the coast. He explains, in a way that is readily understandable to nonscientists, both the science of waves themselves and the technology that can be used to protect us against their more extreme forms, including hurricanes and tsunamis.

The sixth "mass extinction event" in the history of planet Earth is currently under way, with over two hundred species dying off every day. The cause of this seismic event is also the source of the single biggest threat to human life: our own inventions. But for all our talk about sea levels and biotechnology, do we really know what our future will actually look like? Will our immune systems be attacked by so-called super bugs, always evolving, and more easily spread than ever? Will the disappearance of numerous species cripple the biosphere?

Otros mundos devuelve a la vida dieciséis ecosistemas de un pasado inimaginablemente remoto y nos muestra continentes en movimiento, arrecifes de cristal, hongos de tres metros de altura, pingüinos gigantes, reptiles emplumados y muchas otras criaturas asombrosas de un atractivo casi mitológico. A medida que viajamos hacia atrás en el tiempo, redescubrimos nuestro propio hogar de formas irreconocibles, y nos sobrecogen los ecosistemas que se transforman y los devastadores escenarios que han causado el fin de incontables especies.

We have released the genie from the bottle: climate change is coming, and there's no stopping it. The question, according to Matthew Kahn, is not how were going to avoid a hotter future but how were going to adapt to it. In Climatopolis, Kahn, one of the worlds foremost experts on the economics of the environment, argues that cities and regions will adapt to rising temperatures over time, slowly transforming our everyday lives.
