Book excerpt: The Controversy of Climate Change is intended to dispel the myth that climate change is caused by human activities adding vast amounts of greenhouse gases to the atmosphere. The book outlines the reasons the myth exists and continues to be propagated as well as provides the reader with a sound understanding of the earth's atmosphere and each layer's composition; insight into types and amounts of the various greenhouse gases and what they actually do; an initial introduction about the true cause of global climate change and a rudimentary understanding of the forces involved; and a calming conclusion-that we should not worry about it.
