On October 1, 2015, the SS El Faro, a cargo ship tall as a hundred-story building that made a regular run between Jacksonville, Florida, and Puerto Rico, delivering everything from razor blades to new Chevrolet cars, disappeared in Hurricane Joaquin, a category 4 storm. The ship, her hundreds of shipping containers, and her entire crew sank to the bottom of the ocean, three miles down. The sinking was the greatest seagoing US merchant marine shipping disaster since World War II.

In early May of 2005, Captain Tom Tighe and first mate, Loch Reidy, of the sailboat Almeisan welcomed three new crew members, two men and a woman, for a five-day voyage from Connecticut to Bermuda. While Tighe and Reidy had made the journey countless times, the rest of the crew were paying passengers learning about offshore sailing—and looking for adventure. Four days into their voyage, they got adventure but nothing that they had expected or had any training to handle.

Bill Ayers was born into privilege and is today a highly respected educator and community activist. In the late 1960s he was a founder of the militant activist group the Weather Underground. Living on the run, stealing explosives, and hiding from the law, Ayers was involved in the defining moments of his generation: the Days of Rage, SDS, the Black Panthers - and the explosion that killed his beloved comrade, Diana Oughton.

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.

The weather is the foundation of our daily lives. It’s a staple of small talk, the app on our smartphones, and often the first thing we check each morning. Yet behind these quotidian interactions is one of the most expansive machines human beings have ever constructed - a triumph of science, technology, and global cooperation. But what is this "weather machine" and who created it?

What’s in a cloud? Did you know that water vapor is invisible and actually lighter than dry air? What separates a tropical storm from a winter blizzard? And what exactly is El Niño? Elliot Rappaport, a professional captain of traditional sailing ships, has spent three decades at sea, where understanding weather is crucial to the safety of vessels and their crews. In Reading the Glass, he offers a sailor’s-eye view of the moving parts of our atmosphere and unveils the larger patterns it holds: global winds, storms, air masses, jet streams, and the longer arc of our climate.

Every applicable government agency and almost all mainstream media outlets claim that chemtrails are merely a "conspiracy theory". They say that the lines in the sky are harmless condensation trails and that jet aircrafts have always produced emissions that can linger in the sky for hours as they spread out and form a hazy cloud-cover. They say that anybody who asserts that aircraft are routinely spraying us with toxic materials is crazy. If this is so, then why are we consistently seeing anomalously high levels of toxins in rainwater samples as well as in ambient air samples?

Traditional values abound in these hilarious stories from Appalachia: friendship, family, orderliness, humor, and delight in an especially inventive practical joke. In "Rainy Weather", a hound dog with more heart than sense wins everyone's admiration. "Uncle Frank Learns to Speak Polish" finds Davis' famous Uncle Frank making the most of a little foreign language. And, in "Uncle Frank Clean Up the Post Office", cleanliness is next to godliness, and it's also next to hilarity.

Weather affects us almost every day. When it's raining, we can't play outside. Sometimes weather is even more important. Sometimes weather shapes history.

Her only hope is Lewis, the most powerful warden known. Unfortunately, he's stolen not one but three bottles of Djinn-making him the most wanted man on earth. Still, she's racing hard to find him-before the bad weather closes in fast.

Weather includes all the conditions in the air around us. Snow, rain, sleet, and hail are all forms of weather. So is the temperature of the air and the amount of moisture in it. Learn all about weather, including how and why it changes from place to place and time to time.

Hail the size of golf balls drops from the sky. Strong winds send cars sailing through the air as if they were small toys. Most people look for cover when severe weather threatens. But storm chasers do the opposite - they look for the storms! Find out why these daredevils take the risk, what they’ve learned about severe weather, and the gear they use to stay safe.

April 27, 2011, marked the climax of a superstorm that saw a record 358 tornadoes rip through 21 states in 3 days, 7 hours, and 18 minutes. It was the deadliest day of the biggest tornado outbreak in recorded history, which saw 348 people killed, entire neighborhoods erased, and $11 billion in damage. But from the terrible destruction emerged everyday heroes, neighbors, and strangers who rescued each other from hell on earth.

Oklahomans have long been known for their fatalism and grit, but even old-timers are troubled by the twisters that are devastating the state with increasing frequency. On May 20, 2013, the worst tornado on record landed a direct hit on the small town of Moore, destroying two schools while the children cowered inside.

1816 was a remarkable year - mostly for the fact that there was no summer. As a result of a volcanic eruption at Mount Tambora in Indonesia, weather patterns were disrupted worldwide for months, allowing for excessive rain, frost, and snowfall through much of the Northeastern US and Europe in the summer of 1816.

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.
