“Sky Alert! What Happens When Satellites Fail” explores for the first time what our modern world would be like if we were suddenly to lose most, if not all, of our space assets. The author demonstrates humankind’s dependence on space satellites and show what might happen to various aspects of our economy, defense, and daily lives if they were suddenly destroyed. The book opens with a consideration of how our space assets might be lost in the first place: through orbital debris, war, and solar storms. The author then looks at what would happen if our satellites were lost, including the effect on weather forecasting, and the Global Positioning System, explaining GPS in detail and its importance to the military, including spy satellites and military reconnaissance, commerce, civilians, communications and remote sensing – both resource monitoring and locating and environmental monitoring and science. The effects of losing such assets as the International Space Station as well as such research satellites as the Hubble Space Telescope or the Chandra X-Ray Observatory are also considered. Part III of the book looks at how we can protect our satellites, preparing for the worst, reducing the growth and amount of orbital debris, preventing acts of war in space and hardening against space radiation. The book ends on an optimistic note: most spacefaring nations are now working together to develop new technologies to reduce the threat posed by orbital debris and in-space nuclear detonations and treaties exist to limit the development and use of weapons in space. Finally, it is hoped that it will not be long before we will be able to better predict and take precautions against solar storms. The global economy has now become so dependent upon satellites that their loss would be devastating – to the economy, to national security, and potentially, to the day-to-day survival of those who live in the world’s most advanced economies.

At present, the intensification of global climate and environmental change has led to frequent occurrence of natural hazards. Various types of natural hazards always overlap and interact, or occur in a chain reaction, with a wide range of impacts and a long period of time, resulting in serious disaster losses. Typically, major earthquakes and geological hazards, extreme meteorological hazards, large-scale floods and droughts, marine disasters, and forest and grassland fires, as well as their compound and chained hazards are among the key factors affecting human life safety and world economic development. To better our understanding of disaster prevention, mitigation, and relief, it is thus pivotal to facilitate advanced perception, intelligent early warning, accurate prevention, and efficient rescue of natural hazards. This Research Topic aims to collect both Original Research and Review articles addressing the state-of-the-art advances of theories and methodologies in all types of natural hazards. Studies underlining the compound and chained relationship between different hazards are in particular welcomed. Potential themes include, but are not limited to: • Mechanisms of formation, evolution, and disaster process of multiple natural hazards as well as their compound and chained natural hazards • Model and scenario development regarding whole process control, chain breaking of key nodes, and precise prevention of major natural hazard chains • Methods and applications on detection, identification, database establishment, and spatiotemporal evolution law analysis of natural hazard sources • Technologies on intelligent early warning and refined risk assessment of compound and chained natural hazards. • Rescue equipment and investigation of post-disaster community reconstruction

A fascinating look at one of the greatest conservation success stories of the modern era: the wildly popular, unique, and thrilling raptor, the Osprey. Ospreys are one of the few bird species that are found throughout the world. From forests in Hokkaido to rivers in Oregon and islands off Australia, Ospreys steal the show as nature lovers easily watch them build their massive nests and tend to their young. The fact that the Osprey is one of the few large birds that can hover adds to its mystique, and to watch it plunge into the water, emerging with a fish clutched in its talons, is truly a sight one will remember. As widespread as Ospreys are, not long ago they were under threat of extinction. During the 1950s and '60s, scientists tied the decline of Osprey populations to the heavy use of DDT and other human pollutants. In the 1980s, Ospreys began a slow recovery due to the efforts of conservationists and through the resilience of the adaptable raptors themselves. Today they are again considered common in most parts of the world, although some populations remain threatened. In this gorgeously illustrated book, Alan F. Poole, one of America's premier Osprey experts, has written a lyrical exposé of these majestic creatures, describing their daily habits and exploring their relationship with the environment. Ospreys celebrates the species' miraculous recovery from contaminants and hunters, chronicles their spectacular long-distance migrations, and unveils their vital role in bringing life to coastal habitats. Few other birds have such a hold on the human imagination. This book shows us why.
