- Intervention Earth : life-saving ideas from the world's climate engineers / by Dyer, Gwynne,author.;
Includes bibliographical references and index.Historian, journalist, and author Gwynne Dyer tracks down the world's top climate engineers to discuss the extraordinary measures we must contemplate to counter the irreversible effects of climate change. The global climate emergency is now an alarming fact of life. Much as we still need to get emissions under control, many are thinking that it's all too little, too late. As scientists, politicians and concerned citizens scramble for solutions to the catastrophic effects of a warming world, is it time to be exploring the controversial topic of geoengineering? For decades, discerning readers have turned to journalist and historian Gwynne Dyer for his unparalleled acumen in serving up hard geopolitical truths. 'Intervention Earth' is built around Dyer's interviews with sixty climate scientists from around the globe, including the leading figures in the geoengineering field. One of the most interesting topics: the pros and cons of Solar Radiation Management, a possible planetary Hail Mary that is rife with political risks. But 'Intervention Earth' is about more than technological mega-projects. Dyer devotes ample space to the many innovative ideas on offer, but there is no get-out-of-jail-free card. We will need a whole portfolio of techniques and technologies-and a lot of hard, thankless work-to keep the planet hospitable for humanity. What's more, many of the technologies that can help us avoid the worst outcomes require years of investment and development before they can be successfully deployed. Global cooperation will be key in implementing the life-saving strategies outlined in the book. 'Intervention Earth' offers a probing, eye-opening look at the problems we face, and the innovations that just might keep us ahead of encroaching disaster and carry us to a safe harbour.- Subjects: Climate change mitigation.; Environmental engineering.; Solar radiation.;

- The spinning magnet : the force that created the modern world and could destroy it / by Mitchell, Alanna,author.;
Includes bibliographical references and index."The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization. Award-winning science journalist Alanna Mitchell tells in The Spinning Magnet the fascinating history of one of the four fundamental physical forces in the universe, electro-magnetism. From investigations into magnetism in 13th century feudal France and the realization six hundred years later in the Victorian era that electricity and magnetism were essentially the same, to the discovery that the earth was itself a magnet, spinning in space with two poles and that those poles aperiodically reverse, this is an utterly engrossing narrative history of ideas and science that readers of Stephen Greenblatt and Sam Kean will love. But the recent finding that the Earth's magnetic force field is decaying ten times faster than previously thought, portending an imminent pole reversal, ultimately gives this story a spine tingling urgency. When the poles switch, a process that takes many years, the Earth is unprotected from solar radiation storms that would, among other things, wipe out all electromagnetic technology. No satellites, no internet, no smart phones--maybe no power grid at all. Such potentially cataclysmic solar storms are not unusual. The last one occurred in 2012 and we avoided returning to the dark ages only because the part of the sun that erupted happened to be facing away from the Earth. One leading US researcher is already drawing maps of the parts of the planet that would likely become uninhabitable."--- Subjects: Geomagnetism.; Magnetic pole.; Electromagnetism.; Civilization, Modern;
