School Library Journal-Rezension
Gr 7 Up-What makes this program unique is its use of a time line of 650 million years of climate change that reviews facts and theories about global warming. Graphics, special effects, and on-location filming complement the scientists who explain the Earth's cycles of warming and cooling throughout history. Various theories are offered, but there is no doubt that carbon dioxide emissions are heatingthe atmosphere and human activity is changing Earth's weather cycles. Study of ice cores reveal a history of the Earth's past weather and form the basis for predicting rising temperatures and melting polar ice caps that will eventually drown island nations and inundate coastlines of others. The film concludes by asking: "Can humans adapt?" Can something be done to stop mass extinctions and decrease carbon emissions? Can the people of the world cooperate? The DVD is divided into chapters that facilitate classroom use. Quick editing and lack of scientific jargon will hold the attention of students.-Patricia Ann Owens, Wabash Valley College, Mt.

Library Journal-Rezension
Viewers not well versed in the issues currently under debate and proven regarding global warming may find this film a bit over the top. The producers have clearly bought into the idea that planet Earth is getter warmer as we continue to emit greenhouse gases that trap heat in the atmosphere. While the DVD illustrates how we are destroying our planet, there is little discussion of how the governments of the world can stop this calamity. On the other hand, there are those who would argue that "global warming" is not a global problem at all. This documentary may be a good starting point for the novice exploring the origins and ever-changing state of the impact of global warming, but, to elucidate the problem fully, the History Channel could have produced a more informative DVD focusing on what countries are or are not doing to address this controversial issue. An optional purchase for the environmental crowd.-LaRoi Lawton, Lib. & Learning Resources, Bronx Community Coll., CUNY (c) Copyright 2010.
