The climatic effects of rising CO 2 levels will become increasingly significantin the future. Consumption of estimated reserves of fossil fuels in the next two or three centuries will add far more CO 2 to the atmosphere than has been emitted to date unless ambitious conservation efforts or technological innovations reduce the influx. Atmospheric CO 2 concentrations will increase to levels at least twice and possibly four times the highest amounts measured in the last 800,000 years spanned by ice-core records. This warming will overwhelm natural variations in climate and cause climatic and environmental changes unprecedented in human experience. Atmospheric CO 2 levels will eventually decrease as the ocean slowly absorbs much of the excess carbon, but this process will acidify the oceans. After the main pulse of fossil-fuel emissions has passed, atmosphericCO 2 values will decrease back toward preindustrial levels, but enough CO 2 willremain in the atmosphere to prevent future glaciations for tens of thousands of years.
