Alanna Mitchell

The mystery of Earth's invisible, life-supporting power Alanna Mitchell's globe-trotting history of the science of electromagnetism and the Earth's magnetic field--right up to the latest indications that the North and South Poles may soon reverse, with apocalyptic results--will soon change the way you think about our planet. Award-winning journalist Alanna Mitchell's science storytelling introduce intriguing characters--from the thirteenth-century French investigations into magnetism and the Victorian-era discover that electricity and magnetism emerge from the same fundamental force to the latest research. No one has ever told so eloquently how the Earth itself came to be seen as a magnet, spinning in space with two poles, and that those poles have dramatically reversed many time, often coinciding with mass extinctions. The most recent reversal was 780,000 years ago. Mitchell explores indications that the Earth's magnetic force field is decaying faster than previously thought. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other disturbances, wipe out much and possible all of our electromagnetic technology. Navigation for all kinds of animals is disrupted without a stable, magnetic North Pole. But can you imagine no satellites, no Internet, no smartphones--maybe no power grids at all? Alanna Mitchell offers a beautifully crafted narrative history of surprising ideas and science, illuminating invisible parts of our own planet that are constantly changing around us.

The Electromagnetic Force That Created the Modern World--and Could Destroy It

The Spinning Magnet

Globally the oceans cover 71 per cent of the planet's surface and contain 90 per cent of the mass of life on Earth. While tremendous attention and money have been invested in saving the ecosystems of our land animals and plants, the gradual deterioration of ocean life has been happening in secret. Scientists are just beginning to piece together the growing crisis beneath the waves and its implications for future life on this planet. Seasick is the first book to take the scattered pieces of this scientific puzzle and bring them into a cohesive story. It will change the way people understand the global ocean and its importance to all life on earth.

The Hidden Ecological Crisis of the Global Ocean

Seasick

North is north and south is south. Or is it' Without electromagnetism, life on Earth would not be possible. The quest to understand it began with the idea that the magnet was a physical embodiment of the heavens, possessing as it did its own North and South poles. Could the discovery that, every once in a long while, the Earth 's magnetic poles switch places, significantly weakening the field 's protective power, be its end' It 's never happened in the history of humankind, but it has happened many times before and it will happen again - Alanna Mitchell travels the world to unveil the history of this enigmatic force, introducing the enchanting figures whose investigations into magnetism began in the thirteenth century and revealing how later scientists made their pivotal discoveries. The Spinning Magnet is a warning of a future where solar radiation storms wipe out power grids and electronic communications, but it is also a beautifully crafted narrative of one of the most powerful forces in the universe.

The Force That Created the Modern World and Could Destroy It

All life — whether on land or in the sea — depends on the oceans for two things: • Oxygen. Most of Earth’s oxygen is produced by phytoplankton in the sea. These humble, one-celled organisms, rather than the spectacular rain forests, are the true lungs of the planet. • Climate control. Our climate is regulated by the ocean’s currents, winds, and water-cycle activity. Sea Sick is the first book to examine the current state of the world’s oceans — the great unexamined ecological crisis of the planet — and the fact that we are altering everything about them; temperature, salinity, acidity, ice cover, volume, circulation, and, of course, the life within them. Alanna Mitchell joins the crews of leading scientists in nine of the global ocean’s hotspots to see firsthand what is really happening around the world. Whether it’s the impact of coral reef bleaching, the puzzle of the oxygen-less dead zones such as the one in the Gulf of Mexico, or the shocking implications of the changing Ph balance of the sea, Mitchell explains the science behind the story to create an engaging, accessible yet authoritative account.

The Global Ocean in Crisis

Sea Sick

John Geiger

The greatest mystery in all of exploration is the fate of the 1845–1848 British Arctic Expedition commanded by Sir John Franklin. All 129 crewmen died, and the two ships seemingly vanished without a trace. The expedition's destruction was a mass disaster spread over two years. With the vessels beset and abandoned, the crew confronted a horrific ordeal. They suffered from lead poisoning, were stricken with scurvy and, ultimately, resorted to cannibalism in their final days. The mysterious fate of the ships, HMS Erebus and HMS Terror, has captured the public's imagination for seventeen decades. Now, one of Franklin's lost ships has been found. During the summer of 2014, the Victoria Strait Expedition, the largest effort to find the ships since the 1850s, was led by Parks Canada in partnership with the Arctic Research Foundation, The Royal Canadian Geographical Society, and other public and private partners. The expedition used world-leading technology in underwater exploration and succeeded in a major find—the discovery of Erebus. News of the discovery made headlines around the world. In this fully illustrated account, readers will learn about the exciting expedition, challenging search and the ship's discovery. Featuring the first images of the Erebus, this stunning book weaves together a story of historical mystery and modern adventure.

The Historic Discovery of HMS Erebus

Franklin's Lost Ship

Many times through deep history Earth’s magnetic poles have switched places, leaving our planet’s protective shield weaker and life vulnerable to devastating solar storms. The last time it happened was 780,000 years ago, long before humans emerged, but it won’t be long until it happens again. And when it does, will it send us back to the Stone Age? The Spinning Magnet is a fascinating insight into what may lie ahead. From the pivotal discoveries of Victorian scientists to the possibility of solar radiation wiping out power grids, and the secrets of electromagnetism, Alanna Mitchell reveals the truth behind one of the most powerful forces in the universe.

The Force That Created the Modern World – and Could Destroy It

We have long lorded over the ocean. But only recently have we become aware of the myriad life-forms beneath its waves. We now know that this delicate ecosystem is our life-support system; it regulates the earth’s temperatures and climate and comprises 99 percent of living space on earth. So when we change the chemistry of the whole ocean system, as we are now, life as we know it is threatened. In Seasick, veteran science journalist Alanna Mitchell dives beneath the surface of the world’s oceans to give readers a sense of how this watery realm can be managed and preserved, and with it life on earth. Each chapter features a different group of researchers who introduce readers to the importance of ocean currents, the building of coral structures, or the effects of acidification. With Mitchell at the helm, readers submerge 3,000 feet to gather sea sponges that may contribute to cancer care, see firsthand the lava lamp–like dead zone covering 17,000 square kilometers in the Gulf of Mexico, and witness the simultaneous spawning of corals under a full moon in Panama. The first book to look at the planetary environmental crisis through the lens of the global ocean, Seasick takes the reader on an emotional journey through a hidden realm of the planet and urges conservation and reverence for the fount from which all life on earth sprang.
