Global Warming by Seymour Simon What exactly is global warming? What can you do to save the environment? Award-winning science writer, Seymour Simon, has written another outstanding volume in the Smithsonian series. Since the end of the last ice age, 11,000 years ago, the Earth has become warmer. In recent decades, there has been a dramatic rise in temperature. Why is the climate changing? Global warming is happening because of the greenhouse effect: heat is being trapped near the ground by carbon dioxide, water vapor, and greenhouse gases in the atmosphere. People cause global warming by cutting down trees, driving cars and trucks, and burning coal and oil. There is thirty percent more carbon dioxide in the atmosphere than 150 years ago and every year the Arctic Ocean ice shrinks in size and depth. Glaciers and mountain snows are rapidly melting. At the end of this book, the author provides guidelines for what nations, families, and individuals can do on a daily basis to halt rapid global warming. In this informative and well-written book, Seymour Simon takes readers on a journey through the root causes of global warming and provides practical tips for how young people can make a difference in the world.
