Additional Details ------------------------------ Product description: What's coming next-global warming? global cooling? Is man and his use of fossil fuels responsible for the temperature rise observed in the first half of the 20th century? Is it possible to look back in time and see if similar or even greater warming periods as well as extreme cold have occurred in the past? Do the ice core records taken from the vast storehouses of snow and ice in Greenland and Antarctica hold the secrets that can answer these important questions? In Secrets in Polar Ice the authors use data provided by the ice cores along with historical records to reveal the impact that changing climates have had on the rise and fall of nations. The impact of climate change related to famines and the outbreak of pandemic plagues is also shown.
