How might the world as we know it end? In this illustrated guide, How Stuff Works author Marshall Brain explores myriad doomsday scenarios and the science behind them. What if the unimaginable happens? A nuclear bomb detonates over a major city, for example, or a deadly virus infects millions around the world. There are other disasters we don’t even have to imagine because they’ve already occurred, like violent hurricanes or cataclysmic tsunamis that have caused horrific loss of life and damage. In The Doomsday Book, Marshall Brain explains how everything finally ends—the decimation of nations and cities, of civilization, of humanity, of all life on Earth. Brain takes a deep dive into a wide range of doomsday narratives, including manmade events such as an electromagnetic pulse attack, a deadly pandemic, and nuclear warfare; devastating natural phenomena, such as an eruption from a super-volcano, the collapse of the Gulf Stream, or lethal solar flares; and science-fiction scenarios where robots take over or aliens invade. Each compelling chapter provides a detailed description of the situation, the science behind it, and ways to prevent or prepare for its occurrence. With fun graphics and eye-catching photographs at every turn, The Doomsday Book will be the last book you’ll ever have to read about the last days on Earth. Scenarios include: - Asteroid Strike: a massive asteroid could obliterate life—just as it might have killed the dinosaurs. - Gray Goo: self-replicating nanobots engulf the planet. - Grid Attack: an attack on our power grid shuts down the internet, affecting airports, banks, computers, food delivery, medical devices, and the entire economic system. - Gulf Stream collapse: the shutdown of this important ocean current causes temperatures to plummet. - Ocean acidification: if the oceans’ pH levels shift due to a rise in carbon dioxide, all marine life could die.

An astounding tale of a dangerous quest, a talking dog, and fragmented fairy tales in an eerie post-climate collapse future. A long time ago, the Vanderchucks fled the growing climate disaster and followed their neighbours into the Underground. Jesse Vanderchuck thought it was the end. Of the world. Of life. Eventually, Jesse’s little sister, Olivia, ran away and Jesse started picking through trash heaps in Toronto’s abandoned subway tunnels. Day in, day out. Now, years later, Jesse meets a talking dog. Fighting illness and the hostile world aboveground, Jesse and Doggo embark on a fool’s errand to find Olivia — or die trying. Along the way, Jesse spins a series of fairy tales from threads of memories, weaving together the past, present, and future into stories of brave girls, of cunning lads, of love in the face of wickedness, and of hope in the midst of despair.

What is the relationship between general practitioners (GPs) and hospital consultants in the United Kingdom? How does government health policy impact upon GPs and hospital consultants? What influence does the medical profession have upon policy makers in the United Kingdom? The medical profession occupies a dominant position within the British health care system and as such is able to influence the development and implementation of health policy. The main division within the medical profession lies between general practitioners and hospital consultants. This book provides a comprehensive analysis of British health policy over the past twenty-five years. Drawing on data from case studies, it provides empirical evidence of the impact of recent health policies upon the National Health Service (in general) and the medical profession (in particular). The case studies provide an analysis of the impact of the 1991 NHS reforms, as well as examining the ongoing influence of the post 1999 NHS reforms upon these intraprofessional relations. What emerges is that the relationship between GPs and hospital consultants is transforming from a collegial to a more managerial relationship. This book sheds light on the resulting development of intraprofessional relations between GPs and hospital consultants within the NHS. Restructuring the Medical Profession is key reading for undergraduate and postgraduate students, researchers and professionals in the fields of social policy and health policy. It is also of interest to health service practitioners, health service researchers and health policy makers.
