" Our Choice will change the way we read books. And quite possibly change the world. In this interactive app, Al Gore surveys the causes of global warming and presents groundbreaking insights and solutions already under study and underway that can help stop the unfolding disaster of global warming. Our Choice melds the vice president's narrative with photography, interactive graphics, animations, and more than an hour of engrossing documentary footage. A new, groundbreaking multi-touch interface allows you to experience that content seamlessly. Pick up and explore anything you see in the book; zoom out to the visual table of contents and quickly browse though the chapters; reach in and explore data-rich interactive graphics. "
"Our climate is changing. The planet is warming faster than at any time in the last 10,000 years. Global average temperatures have risen by 0.8ºC since the late 19th century, and 0.2ºC per decade over the past 25 years. Man-made greenhouse gas emissions have caused, and continue to cause, most of the observed temperature rise since the mid 20th century. Millions of tonnes of greenhouse gases are produced every day by human activity. These constant emissions into the Earth's atmosphere continue to drive global warming. "
