Even as climate change dominates the headlines, many of us still think about it in the future tense—we imagine that as global warming worsens over the coming decades, millions of people will scatter around the world, fleeing famine and rising seas. What we often don’t realize is that the consequences of climate change are already visible, right here in the United States. In communities across the country, climate disasters are pushing thousands of people away from their homes.

Susan Casey is our premiere chronicler of the aquatic world. For The Underworld she traversed the globe, joining scientists and explorers on dives to the deepest places on the planet, interviewing the marine geologists, marine biologists, and oceanographers who are searching for knowledge in this vast unseen realm. She takes us on a fascinating journey through the history of deep-sea exploration, from the myths and legends of the ancient world to storied shipwrecks we can now reach on the bottom.

In May 2016, Fort McMurray, the hub of Canada’s oil industry and America’s biggest foreign supplier, was overrun by wildfire. The multi-billion-dollar disaster melted vehicles, turned entire neighborhoods into firebombs, and drove 88,000 people from their homes in a single afternoon. Through the lens of this apocalyptic conflagration—the wildfire equivalent of Hurricane Katrina—John Vaillant warns that this was not a unique event, but a shocking preview of what we must prepare for in a hotter, more flammable world.

When Elon Musk was a kid in South Africa, he was regularly beaten by bullies. One day a group pushed him down some concrete steps and kicked him until his face was a swollen ball of flesh. He was in the hospital for a week. But the physical scars were minor compared to the emotional ones inflicted by his father, an engineer, rogue, and charismatic fantasist.

The world is waking up to a new reality: wildfires are now seasonal in California, the Northeast is getting less and less snow each winter, and the ice sheets in the Arctic and Antarctica are melting fast. Heat is the first order threat that drives all other impacts of the climate crisis. And as the temperature rises, it is revealing fault lines in our governments, our politics, our economy, and our values. The basic science is not complicated: Stop burning fossil fuels tomorrow, and the global temperature will stop rising tomorrow.

Five oceans—the Atlantic, the Pacific, the Indian, the Arctic, and the Southern—cover approximately 70 percent of the earth. Yet we know little about what lies beneath them. By the early 2020s, less than twenty-five percent of the ocean’s floor has been charted, most close to shorelines, and over three quarters of the ocean lies in in what is called the Deep Sea, depths below a thousand meters.

What if Atlantis wasn't a myth but an early precursor to a new age of great flooding? Across the globe, scientists and civilians alike are noticing rapidly rising sea levels and higher and higher tides pushing more water directly into the places we live, from our most vibrant, historic cities to our last remaining traditional coastal villages. With each crack in the great ice sheets of the Arctic and Antarctica and each tick upward of Earth's thermometer, we are moving closer to the brink of broad disaster.

We are approaching a critical threshold in the history of our species. Everything is about to change. Soon you will live surrounded by AIs. They will organize your life, operate your business, and run core government services. You will live in a world of DNA printers and quantum computers, engineered pathogens and autonomous weapons, robot assistants and abundant energy.

What if you woke up one morning and found you’d acquired another self—a double who was almost you and yet not you at all? What if that double shared many of your preoccupations but, in a twisted, upside-down way, furthered the very causes you’d devoted your life to fighting against? Not long ago, the celebrated activist and public intellectual Naomi Klein had just such an experience—she was confronted with a doppelganger whose views she found abhorrent but whose name and public persona were sufficiently similar to her own that many people got confused about who was who.

In 1956, the New York Times prophesied that once global warming really kicked in, we could see parrots in the Antarctic. In 2010, when science deniers had control of the climate story, Senator James Inhofe and his family built an igloo on the Washington Mall and plunked a sign on top: AL GORE'S NEW HOME: HONK IF YOU LOVE CLIMATE CHANGE. In The Parrot and the Igloo, bestselling author David Lipsky tells the astonishing story of how we moved from one extreme (the correct one) to the other.

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.

How much of our daily caloric intake comes from ingesting substances that, technically speaking, do not meet traditional definitions of “food”? Chances are, if you’re eating something that came wrapped in plastic and contains a funky ingredient you don’t have in your kitchen, it's most likely—almost definitely—ultra-processed food, or UPF.

Bestselling Hollywood biographer and film historian Scott Eyman tells the story of Charlie Chaplin’s fall from grace. In the aftermath of World War II, Chaplin was criticized for being politically liberal and internationalist in outlook. He had never become a US citizen, something that would be held against him as xenophobia set in when the postwar Red Scare took hold. In Charlie Chaplin vs. America, Scott Eyman explores the life and times of the movie genius who brought us such masterpieces as City Lights and Modern Times.

In the 1950s, an obsessive firearms designer named Eugene Stoner invented the AR-15 rifle in a California garage. High-minded and patriotic, Stoner sought to devise a lightweight, easy-to-use weapon that could replace the M1s touted by soldiers in World War II. What he did create was a lethal handheld icon of the American century.

For millennia, owls have captivated and intrigued us. Our fascination with these mysterious birds was first documented more than thirty thousand years ago in the Chauvet Cave paintings in southern France. With their forward gaze and quiet flight, owls are often a symbol of wisdom, knowledge, and foresight. But what does an owl really know? And what do we really know about owls? Jennifer Ackerman illuminates the rich biology and natural history of these birds and reveals remarkable new scientific discoveries about their brains and behavior.
