Children's Literature - Suzanna E. Henshon
Why are polar bears in trouble? Why is the Arctic Ocean becoming warmer? The Arctic Ocean is very cold and covered with floating ice, but it is just the right temperature for polar bears who live on the ice and hunt seals. Every year, the Arctic temperature slowly rises, and more and more ice melts. It is harder for Polar bears to survive and thrive with ice floes few and far in between. In order to be a healthy planet, the earth must maintain equilibrium; the average temperature must stay around 59 degrees Fahrenheit, and the main greenhouse gases must stay at a healthy level. At this point in time, there are too many greenhouse gases in the air, and the air is becoming too warm. Most of the carbon dioxide comes from factories and machines that burn fossil fuels like coal and oil. People are using more and more electricity, causing carbon dioxide to go into the air. Every day millions of people use oil when they drive cars, fly planes, and sail in ships. So how important is Arctic ice, and why does it matter that we work to save it? Arctic ice helps regulate weather all over the world. In this fun book, children can see the link between ice floes, the greenhouse effect, and a myriad of problems that could have long-lasting consequences. The author provides examples of what parents and children can do on a regular basis to conserve energy (and save the Arctic ice) so that Polar bears will be around for many years to come.

Gr 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

Kirkus Reviews
A worthy title that uses polar bears and the melting of the Arctic ice as a springboard for an explanation of global warming pitched well to preschool audiences. Simple language and vivid imagery serve to communicate a difficult subject, effectively making the connection between the burning of fossil fuels and the warming of the atmosphere. Wells's text flows evenly through his explanations back to the reason why the Arctic ice matters to all of us, not just polar bears. How can readers help? A list of child-accessible solutions concludes the presentation. Clear diagrams and illustrations, with a trio of personable polar bears (a mother and two cubs) accompanying two children around the world, move the text along nicely. Some pack quite a punch: A stack of the 700 million cars in the world, three to a layer, stretches from Earth to the moon. A fine addition to early science collections.
