With this book, the author, former Vice President Al Gore brings together leading-edge research from top scientists around the world; photographs, charts, and other illustrations; and personal anecdotes and observations to document the fast pace and wide scope of global warming. He presents, with alarming clarity and conclusiveness - and with humor, too—that the fact of global warming is not in question and that its consequences for the world we live in will be disastrous if left unchecked.
