Today we review a geophysical history of the earth from the days when carbon and biological life were not present, through the evolution of the biosphere over 4 Billion years and photosynthesis to the advent of animal and plant life some 460 million years ago, modern humans 195, 000 years ago to the farming of land 10,000 years ago and the build-up of carbon dioxide in the atmosphere and the beginning of a new geological epoch, the Anthropocene. This history not only puts the significance of global climate change into context but it also shows the ways that man has literally changed the world.
