In the Arctic, the summer ice is melting, making it hard for polar bears to survive. Why is the world getting warmer? The heat of the sun is trapped by the "greenhouse" gases that surround Earth--carbon dioxide, methane, nitrous oxide, and water vapor.

Editorial Reviews
From School Library Journal
Grade 1–4—Two children sail in a red research vessel through the pages of this clear and simple explanation of global warming. Colorful, cartoon drawings show the youngsters rescuing a mother polar bear and her two cubs by hauling them onto their boat. Then, beginning with an explanation of the sun's effect on the Earth's atmosphere, they pursue the reasons that the Arctic ice is melting. Without oversimplifying, Wells makes the large concepts of the Greenhouse Effect and the sources of CO2 understandable for young children. He doesn't shy away from the frightening possible effects of warming: floods, drought, and an increase in storm intensity, but he ends with a reassuring list of behaviors that readers can do on their own or discuss with adults. An excellent introduction to the topic for primary-grade children.—Ellen Heath, Easton Area Public Library, Easton, PA

Polar Bear book rocked!,
Amazon Verified Purchase(What's this?)
This review is from: Polar Bear, Why Is Your World Melting? (Paperback)
I wasn't sure if this book would serve its purposes for my class based on the online preview. But when I actually opened the book and used it for my English Class to add to a unit based on Global Warming, it was perfect!
