I review the evidence of natural climate change as given by the Greenland ice core data of the past 120,000 years and the Antarctica ice core data of the past 900,000 years. These data show that the atmospheric carbon dioxide concentration never exceeded 300 ppm (parts per million by volume) during the 650,000 years which preceded AD 1900. Only around 1900 did the concentration reach 300 ppm. Afterwards it increased continuously until the present value of over 400 ppm, where since AD 2000 it increases by 2 ppm per year. I predict that within the next one hundred years the global temperature will increase by further 3.6°C only because of the carbon dioxide concentration that is already at present in the atmosphere.
