Trace gases are those that are present in the atmosphere at relatively low concentrations. Small changes in their concentrations can have profound implications for major atmospheric fluxes, and thereore, can be used as indicators in studies of global change, global biogeochemical cycling and global warming. This new how-to guide will detail the concepts and techniques involved in the detection and measurement of trace gases, and the impact they have on ecological studies. Introductory chapters look at the role of trace gases in global cycles, while later chapters go on to consider techniques for the measurement of gases in various environments and at a range of scales. A how-to guide for measuring atmospheric trace gases.Techniques described are of value in addressing current concerns over global climate change.

In this new collection of short stories, from the author of Watch City and Sometimes Things Go Horribly Wrong, a variety of complex characters encounter desperate choices and life-changing decisions. A college student must decide whether to join his family in an apocalyptic suicide pact, or attempt to survive a potentially endless winter. A cancer patient undergoing radical experimental treatment is given the choice between saving his own life, and the life of a complete stranger. A substitute high school teacher decides to break protocol, and teach his students what life in the real world really entails. The stories of The Last Three Hours will submerge readers in the implications of decisions both large and small, choices both life-altering and life-affirming. What would you do with only one lifetime? With only a few years to live? With only a few hours?
