Global warming - Sally Morgan

Global Warming looks at the causes of climate change and its profound effect for life on Earth. It shows how historical clues, such as ice cores, are evidence that temperature fluctuation is not a new phenomenon, and how the causes of our current changing climate are a result of human activity. Learn about dramatic heat waves, coral bleaching, El Nio events, and how methane and CFCs affect the atmosphere. Consider the uses of renewable and alternative energy sources, from powering cars and homes with photovoltaic cells, to erecting vast wind farms and nuclear power stations.
