At the end of the last century, Johnstown, Pennsylvania, was a booming coal-and-steel town filled with hardworking families striving for a piece of the nation's burgeoning industrial prosperity. In the mountains above Johnstown, an old earth dam had been hastily rebuilt to create a lake for an exclusive summer resort patronized by the tycoons of that same industrial prosperity, among them Andrew Carnegie, Henry Clay Frick, and Andrew Mellon.

The fascinating science and history of the air we breathe. It's invisible. It's ever present. Without it, you would die in minutes. And it has an epic story to tell. In Caesar's Last Breath, New York Times best-selling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it.

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.

The paths of the great American robber barons were paved with riches, and though ordinary citizens paid for them, they also profited.

At 01:23:40 on April 26th 1986, Alexander Akimov pressed the emergency shutdown button at Chernobyl's fourth nuclear reactor.

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.

The year is 1925. It is sixty degrees below zero. The wind sweeps tons of snow over the deep-frozen Alaskan landscape. The nearest railhead is seven hundred miles away. Airplanes cannot fly. The way to Nome is blocked by a treacherous frozen sound, an icebound port, and mountains to the west. But there is a diphtheria epidemic in Nome. The children need serum from the outside world if they are to survive. Their only hope is a few chosen Eskimo drivers and their teams of dogs.

The dust storms that terrorized the High Plains in the darkest years of the Depression were like nothing ever seen before or since. Following a dozen families and their communities through the rise and fall of the region, Timothy Egan tells of their desperate attempts to carry on through blinding black dust blizzards, crop failure, and the death of loved ones. Brilliantly capturing the terrifying drama of catastrophe, he does equal justice to the human characters who become his heroes.

On the morning of May 20, 1927, a little-known pilot named Charles Lindbergh waited to take off from Roosevelt Field on Long Island. He was determined to claim the $25,000 Orteig Prize promised to the first pilot to fly nonstop from New York to Paris - a contest that had already claimed six men's lives. Just 25 years old, Lindbergh had never before flown over water. Yet 33 hours later, his single-engine monoplane, The Spirit of St. Louis, touched down in Paris.

Reed Timmer is one of the most successful and most extreme storm chasers in the world. His is a job that requires science and bravado, knowledge and instinct just to survive, never mind excel. It's a job some people would kill for. But most prefer to let Timmer take the risks while they watch from the safety of their homes. Reed Timmer is a star of Storm Chasers, one of the Discovery Channel's top-rated shows. Into the Storm is Timmer's dramatic account of his extraordinary profession.

For months in early 1980, scientists, journalists, and ordinary people listened anxiously to rumblings in the long quiescent volcano Mount St. Helens. Still, when a massive explosion took the top off the mountain, no one was prepared. Fifty-seven people died, including newlywed logger John Killian (for years afterward, his father searched for him in the ash), scientist Dave Johnston, and celebrated local curmudgeon Harry Truman. The lives of many others were forever changed.

Reissued on the 10th anniversary of its publication, this classic work on our environmental crisis features a new introduction by the author, reviewing both the progress and ground lost in the fight to save the Earth. This impassioned plea for radical and life-renewing change is today still considered a groundbreaking work in environmental studies. McKibben's argument that the survival of the globe is dependent on a fundamental, philosophical shift in the way we relate to nature is more relevant than ever.

On the night of September 20, 1938, the news on the radio was full of Hitler's pending invasion of Czechoslovakia. Severe weather wasn't mentioned; only light rain was forecast for the following day. In a matter of hours, however, a hurricane of unprecedented force would tear through one of the wealthiest and most populated stretches of coastline in America, obliterating communities from Long Island to Providence, destroying entire fishing fleets from Montauk to Narragansett Bay.

A gripping narrative history of the 1889 Johnstown Flood - the deadliest flood in US history - from New York Times best-selling author, NBC host, and legendary weather authority Al Roker. May 1889: After a deluge of rainfall swelled the Little Conemaugh River, panicked engineers watched helplessly as swiftly rising waters threatened to breach the South Fork Dam in central Pennsylvania. Though they telegraphed neighboring towns, warning of the impending danger, residents, used to false alarms, remained in their homes. At 3:10 p.m., the dam gave way....
