At 01:23:40 on April 26th 1986, Alexander Akimov pressed the emergency shutdown button at Chernobyl's fourth nuclear reactor. It was an act that forced the permanent evacuation of a city, killed thousands, and crippled the Soviet Union. The event spawned decades of conflicting, exaggerated, and inaccurate stories.

When we talk about human history, we often focus on great leaders, population forces, and decisive wars. But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the southeast United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea.

The millions of people around the world who loved What If? still have questions, and those questions are getting stranger. Thank goodness xkcd creator Randall Munroe is here to help. Planning to ride a fire pole from the Moon back to Earth? The hardest part is sticking the landing. Hoping to cool the atmosphere by opening everyone’s freezer door at the same time? Maybe it’s time for a brief introduction to thermodynamics. Want to know what would happen if you rode a helicopter blade, made a lava lamp out of lava, or jumped on an erupting geyser? Okay, if you insist.

The history of the Great Warming of a half millennium ago suggests that we may yet be underestimating the power of climate change to disrupt our lives todayand our vulnerability to drought, writes Fagan, is the silent elephant in the room.

With the constant threat of oil shortages facing us and wanting to educate herself about possible alternatives, Gwyneth Cravens skeptically sets out to find for herself the truth about nuclear energy. Her conclusion: It is a totally viable and practical solution to global warming. She enlists the help of Rip Anderson, a leading scientist in the field of risk assessment, and with his tutelage, she travels the country, visiting uranium mines, enrichment centers, reactors, and waste sites.

Some 73,000 years ago, the Mount Toba supervolcano in toda's Indonesia erupted, releasing the energy of a million tons of explosives. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop for a decade. In this book, Donald R. Prothero presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide.

From Joseph Romm, Chief Science Advisor for National Geographic's Years of Living Dangerously series and one of Rolling Stone's "100 people who are changing America," Climate Change offers user-friendly, scientifically rigorous answers to the most difficult (and commonly politicized) questions surrounding what climatologist Lonnie Thompson has deemed "a clear and present danger to civilization."

The lives of millions will be changed after it breaks, and yet so few people understand it, or even realize it runs through their backyard. Dvorak reveals the San Andreas Fault's fascinating history - and its volatile future. It is a prominent geological feature that is almost impossible to see unless you know where to look. Hundreds of thousands of people drive across it every day. The San Andreas Fault is everywhere - and primed for a colossal quake. For decades scientists have warned that such a sudden shifting of the Earth's crust is inevitable.

From Hiroshima to Chernobyl, Fukushima to the growing legacy of lethal radioactive waste, humanity's struggle to conquer atomic energy is rife with secrecy, deceit, human error, blatant disregard for life, short-sighted politics, and fear. Fallout is an eye-opening odyssey through the first eight decades of this struggle and the radioactive landscapes it has left behind. We are, Pearce finds, forever torn between technological hubris and all-too-human terror about what we have created.

Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate following. Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent of the speed of light? How fast can you hit a speed bump while driving and live? If there were a robot apocalypse, how long would humanity last?

For any task you might want to do, there's a right way, a wrong way, and a way so monumentally complex, excessive, and inadvisable that no one would ever try it. How To is a guide to the third kind of approach. It's full of highly impractical advice for everything from landing a plane to digging a hole.

An "epoch-defining book" (The Guardian) and "this generation’s Silent Spring" (The Washington Post), The Uninhabitable Earth is both a travelogue of the near future and a meditation on how that future will look to those living through it - the ways that warming promises to transform global politics, the meaning of technology and nature in the modern world, the sustainability of capitalism and the trajectory of human progress. The Uninhabitable Earth is also an impassioned call to action.

Our world has ended five times: It has been broiled, frozen, poison gassed, smothered, and pelted by asteroids. In The Ends of the World, Peter Brannen dives into deep time, exploring Earth's past dead ends, and in the process offers us a glimpse of our possible future. Many scientists now believe that the climate shifts of the 21st century have analogs in these five extinctions.

The legendary annihilation in 1883 of the volcano-island of Krakatoa - the name has since become a byword for a cataclysmic disaster - was followed by an immense tsunami that killed nearly 40,000 people. Beyond the purely physical horrors of an event that has only very recently been properly understood, the eruption changed the world in more ways than could possibly be imagined. Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light.

AI expert Yorick Wilks takes a journey through the history of artificial intelligence up to the present day, examining its origins, controversies, and achievements, as well as looking into just how it works. He also considers the future, assessing whether these technologies could menace our way of life and how we are all likely to benefit from AI applications in the years to come.

We live at the bottom of an ocean of air - 5,200 million million tons, to be exact. It sounds like a lot, but Earth’s atmosphere is smeared onto its surface in an alarmingly thin layer - 99 percent contained within 18 miles. Yet, within this fragile margin lies a magnificent realm - at once gorgeous, terrifying, capricious, and elusive. With his keen eye for identifying and uniting seemingly unrelated events, Chris Dewdney reveals to us the invisible rivers in the sky that affect how our weather works and the structure of clouds and storms and seasons, the rollercoaster of climate.

Laki is Iceland's largest volcano - and its most fearsome. Its eruption in 1783 is one of history's great untold natural disasters. Spewing out sun-blocking ash and then a poisonous fog for eight long months, the effects of the eruption lingered across the world for years. It caused the deaths of people as far away as the Nile and created catastrophic conditions throughout Europe.

After nearly a decade overseas as a war reporter, the acclaimed journalist Dahr Jamail returned to America to renew his passion for mountaineering, only to find that the slopes he had once climbed have been irrevocably changed by climate disruption. In response, Jamail embarks on a journey to the geographical front lines of this crisis - from Alaska to Australia’s Great Barrier Reef, via the Amazon rainforest - in order to discover the consequences to nature and to humans of the loss of ice.

Kenneth C. Davis, author of Don't Know Much About® History, Don't Know Much About the Civil War and Don't Know Much About the Bible, turns his inimitable wit and wide-ranging knowledge to the subject of geography, and proves once and for all that there is a lot more to it than labeling countries on a map. From often amusing perceptions people have had through the ages about the world and the universe to the changing map of today, Davis shows how geography is really a great crossroad of many fields: biology, meteorology, astronomy, history, economics, and even politics.

With A Furious Sky, Eric Jay Dolin has created a vivid, sprawling account of our encounters with hurricanes, from the nameless storms that threatened Columbus's New World voyages to the destruction wrought in Puerto Rico by Hurricane Maria. Weaving a story of shipwrecks and devastated cities, of heroism and folly, Dolin introduces a rich cast of unlikely heroes and puts us in the middle of the most devastating storms of the past, none worse than the Galveston Hurricane of 1900, which killed at least 6,000 people, the highest toll of any natural disaster in American history.

Dust swirled round die planet for years, causing temperatures to plummet and sunsets to turn vivid with lurid and unsettling displays of light.

From the pioneers of Los Alamos who got up close and personal with the cores of atomic bombs, to the hapless engineers in Soviet fuel-processing plants who unwittingly mixed up a disaster in a bucket, and from the terrifying impact of a tsunami at Fukushima to the mystery of the recent Russian incident, Meltdown explores the past and future of this extraordinary and potentially lethal source of infinite power

When Indonesia's Mount Tambora erupted in 1815, it unleashed the most destructive wave of extreme weather the world has witnessed in thousands of years. The volcano's massive sulfate dust cloud enveloped the Earth, cooling temperatures and disrupting major weather systems for more than three years. Amid devastating storms, drought, and floods, communities worldwide endured famine, disease, and civil unrest on a catastrophic scale.

The fascinating, often surprising story of how a simple black rock altered the course of history. Yet the mundane mineral that built our global economy, and even today powers our electrical plants, has also caused death, disease, and environmental destruction. In this remarkable book, Barbara Freese takes us on a rich historical journey that begins three hundred million years ago and spans the globe.

Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

In The Vanishing Face of Gaia, British scientist James Lovelock predicts global warming will lead to a Hot Epoch. Lovelock is best known for formulating the controversial Gaia theory in the 1970s, with Ruth Margulis of the University of Massachusetts, which states that organisms interact with and regulate Earth's surface and atmosphere. We ignore this interaction at our peril.
