This book, which contains 17 chapters, presents an expert synthesis of greenhouse gas (GHG) sink science and how this applies to the past, current and future changes in climate. It also explores how the sinks may respond to increased GHG emissions and global temperatures, and whether they can be protected and even enhanced to help mitigate climatic change. The sinks discussed in this book are the planet's storage areas, where GHGs are locked away from the atmosphere and thus prevented from contributing to global warming. This book is a valuable resource for students, researchers and practitioners in conservation, ecology and environmental studies.

In 2017 the Royal Society and Royal Academy of Engineering were asked by the UK Government to consider scientific and engineering views on greenhouse gas removal. This report draws on a breadth of expertise including that of the Fellowships of the two academies to identify the range of available greenhouse gas removal methods, the factors that will affect their use and consider how they may be deployed together to meet climate targets, both in the UK and globally.

THE ARTICLE EXAMINES THE CURRENT--OFTEN HYSTERICAL--CLAIMS ABOUT GLOBAL WARMING, THE "GREENHOUSE EFFECT." IT CONCLUDES THAT THE THREAT OF GLOBAL WARMING IS SIGNIFICANTLY EXAGGERATED AND POSSIBLY DUE TO OTHER FACTORS THAN INCREASED "GREENHOUSE GASSES" IN THE ATMOSPHERE. HOWEVER, THE POSSIBILITY OF THE DEVASTATING CONSEQUENCES OF GLOBAL TEMPERATURE RISE DO JUSTIFY U.S. MEASURES TO REDUCE THE AMOUNT OF CO2 ADDED TO THE ATMOSPHERE.
