Reading climate changes in an Ice Age map
Long before the age of automobiles, long before the invention of the wheel, natural events caused atmospheric carbon dioxide levels to climb dramtically at the end of the last Ice Age. Uncovering reasons for that increase may help researchers better predict the climatic impact of the present carbon dioxide build-up caused by human activities.
