- Beyond our normal twenty-year outlook period, we recently attempted a forecast of the CO2 [carbon dioxide] build-up. We assumed different growth rates at different times, but with an average growth rate in fossil fuel use of about one percent per year starting today, our estimate is that the doubling of atmospheric CO2 levels might occur sometime late in the 21st century. That includes the impact of a synfuels industry. Assuming the greenhouse effect occurs, rising CO2 concentrations may begin to induce climactic changes around the middle of the 21st century.
