This third edition of the textbook Environmental Physics will be thoroughly revised keeping in mind the importance of sustainable energy and climate change. As fossil fuels and nuclear power will be with us for many years to come, the physical and environmental aspects of these ways of energy conversion are given ample attention as well as atmospheric and soil physics, with the reader being introduced to the physics that is required to understand, analyse and prevent environmental problems. The text utilises examples from diverse areas, such as the more established issues of climate change through to areas of increasing importance, such as sound pollution. Environmental issues are rarely confined by political boundaries, and accordingly, this book attempts to take a global perspective, placing political concerns in a scientific context. Whilst the rigor and methodology has been maintained in the Second Edition there has been a greater integration of physics with the natural environment throughout the text.
