The truth about the climate crisis is an inconvenient one that means we are going to have to change the way we live our lives. Our climate crisis may at times appear to be happening slowly, but in fact it has become a true planetary emergency and we must recognise that we are facing a crisis. So why is it that some leaders seem not to hear the clarion warnings? Are they resisting the truth because they know that the moment they acknowledge it, they will face a moral imperative to act? Is it simply more convenient to ignore the warnings? Perhaps, but inconvenient truths do not go away just because they are not seen, rather, their significance grows. Al Gore, former Vice President of the United States, has been a passionate advocate of action to halt climate change for many years. In "An Inconvenient Truth" Gore writes about the urgent need to solve the problems of climate change, presenting comprehensive facts and information on all aspects of global warming in a direct, thoughtful and compelling way,using explanatory diagrams and dramatic photos to clarify and highlight key issues.The book has been described in the "New York Times" as one which could ''push awareness of global warming to a real tipping point''. The documentary film of the same name, based on the book, premiered at this year''s Sundance Festival to great acclaim.

The truth about the climate crisis is an inconvenient one that means we are going to have to change the way we live our lives - and this affects young people above all. Our climate crisis may at times appear to be happening slowly, but in fact it has become a true planetary emergency and we need to understand that we are facing a crisis. Al Gore, former Vice President of the United States, has been a passionate advocate of action to halt climate change for many years. In this young adult edition of "An Inconvenient Truth", adapted from his acclaimed book and film, he writes about the urgent need to solve the problems of climate change, presenting facts and information on all aspects of global warming in a direct, thoughtful and compelling way, using explanatory diagrams and dramatic photos to clarify and highlight key issues. For this young adult edition, the text has been edited down from 320 to 192 pages, with younger readership in mind, so sections aimed specifically at adults (e.g. insurance implications, investing in energy and political material)and the text) will be omitted in favour of clear text, appropriate photographs and easily understandable graphs.The overall aim is to gear the content to the people who will in fact be dealing with global warming for the rest of their lives.

It is suitable for a two-semester course at the beginning graduate level, requiring as a prerequisite a knowledge of point set topology and basic algebra. Although categories and functors are introduced early in the text, excessive generality is avoided, and the author explains the geometric or analytic origins of abstract concepts as they are introduced, making this book of great value to the student.

This impressive author team brings the wealth of advances in conservation genetics into the new edition of this introductory text, including new chapters on Population Genomics and Genetic Issues in Introduced and Invasive Species. They continue the strong learning features for students - main points in the margin, chapter summaries, vital support with the mathematics, and further reading - and now guide the reader to software and databases. Many new references reflect the expansion of this field. With examples from mammals, birds, reptiles, fish, amphibians, plants and invertebrates, this is an ideal introduction to conservation genetics for a broad audience. The text tackles the quantitative aspects of conservation genetics, and has a host of pedagogy to support students learning the numerical side of the subject.
