Disappointment River is a dual historical narrative and travel memoir that at once transports listeners back to the heroic age of North American exploration and places them in a still rugged but increasingly fragile Arctic wilderness in the process of profound alteration by the dual forces of energy extraction and climate change.

An ardent steward of the land, fearless traveler, and unrivaled observer of nature and culture, Barry Lopez died after a long illness on Christmas Day 2020. The previous summer, a wildfire had consumed much of what was dear to him in his home place and the community around it—a tragic reminder of the climate change of which he’d long warned.

A lifelong acolyte of the natural world, Annie Proulx brings her witness and research to the subject of wetlands and the vitally important role they play in preserving the environment—by storing the carbon emissions that accelerate climate change. Fens, bogs, swamps, and marine estuaries are crucial to the earth’s survival, and in four illuminating parts, Proulx documents their systemic destruction in pursuit of profit. Proulx describes the fens of 16th-century England, Canada’s Hudson Bay lowlands, Russia’s Great Vasyugan Mire, and America’s Okeefenokee National Wildlife Refuge.

Some 40 million miles of roadways encircle the earth, yet we tend to regard them only as infrastructure for human convenience. While roads are so ubiquitous they're practically invisible to us, wild animals experience them as entirely alien forces of death and disruption. In Crossings, environmental journalist Ben Goldfarb travels throughout the United States and around the world to investigate how roads have transformed our planet. A million animals are killed by cars each day in the US alone, but as the new science of road ecology shows, the harms of highways extend far beyond roadkill.

The stories we usually tell ourselves about climate change tend to focus on the damage inflicted on human societies by big storms, severe droughts, and rising sea levels. But the most powerful impacts are being and will be felt by the natural world and its myriad species, which are already in the midst of the sixth great extinction. Rising temperatures are fracturing ecosystems that took millions of years to evolve, disrupting the life forms they sustain--and in many cases driving them towards extinction. The natural Eden that humanity inherited is quickly slipping away.

Five stunningly large forests remain on Earth. These megaforests are vital to preserving global biodiversity, thousands of cultures, and a stable climate, as John W. Reid and Thomas E. Lovejoy argue in Ever Green. Megaforests serve an essential role in decarbonizing the atmosphere, and saving them is the most immediate and affordable large-scale solution to our planet's most formidable ongoing crisis. Reid and Lovejoy offer practical solutions to address the biggest challenges these forests face, from vastly expanding protected areas to supporting Indigenous forest stewards.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

Picture yourself in the Cretaceous period. It’s a sunny afternoon in the Hell Creek of ancient Montana 66 million years ago. A Triceratops horridus ambles along the edge of the forest. In a matter of hours, everything here will be wiped away. Lush verdure will be replaced with fire. Tyrannosaurus rex will be toppled from their throne, along with every other species of non-avian dinosaur no matter their size, diet, or disposition. They just don’t know it yet.

The past is past, but it does leave clues, and Thomas Halliday has used cutting-edge science to decipher them more completely than ever before. In Otherlands, Halliday makes sixteen fossil sites burst to life.

From ants scurrying under leaf litter to bees able to fly higher than Mount Kilimanjaro, insects are everywhere. Three out of every four of our planet's known animal species are insects. In The Insect Crisis, Oliver Milman dives into the torrent of recent evidence that suggests this kaleidoscopic group of creatures is suffering the greatest existential crisis in its remarkable 400-million-year history.

Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites listeners to explore and learn from the elegantly simple lives of mosses.

From tuberculosis to bird flu and HIV to coronavirus, these infectious diseases share a common origin story: Human interaction with animals. Otherwise known as zoonotic diseases for their passage from animals to humans, these pathogens - both pre-existing ones and those newly identified - emerge and re-emerge throughout history, sparking epidemics and pandemics that have resulted in millions of deaths around the world. How did these diseases come about? And what - if anything - can we do to stop them and their fatal march into our countries, our homes, and our bodies?

How do trees live? Do they feel pain or have awareness of their surroundings? Research is now suggesting trees are capable of much more than we have ever known. In The Hidden Life of Trees, forester Peter Wohlleben puts groundbreaking scientific discoveries into a language everyone can relate to.

As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.
